From f1db881f650901bc861994d89f66798a7dc35210 Mon Sep 17 00:00:00 2001 From: Alex Oliveira <4482374+aroff@users.noreply.github.com> Date: Tue, 7 Jul 2026 22:13:58 +0000 Subject: [PATCH 1/8] docs: codebase audit + skill-management specs (design-only) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the design artifacts from the audit + grilling + verification sessions. No implementation yet; these define the work and the decisions behind it. Specs: - specs/002-codebase-issues-audit.md — 38 verified findings (SEC-1..12, BUG-1..15, PARTIAL-1..11) with recommended approaches + interim workarounds; includes a verification pass (SEC-10 refuted, BUG-6 downgraded, BUG-10 escalated) and a coverage pass over previously unaudited modules (git.rs, hot_reload.rs, events/, build_cache.rs, skillopt/*). - specs/003-browser-skill-management.md — browser-based local skill manager (create/edit/add-from-source/delete/upgrade), editable-only edit rule, rides WRITE-GATE. ADRs: - 0003 — serve is read-only by default; mutations behind --enable-write; fastskill is not a security boundary (shared-deploy auth is external). - 0004 — a bare version constraint is an exact pin, not caret; preserve via normalization in the semver::VersionReq migration.

The +audit in [spec 002](../../specs/002-codebase-issues-audit.md) found these routes carry **no in-app +authentication** (SEC-1, SEC-2). + +`fastskill serve` is **local-first and single-user by default**: an operator runs it on their own +machine for a web UI / REST view over their own skills. A **deployed mode** (container behind an +edge proxy) is supported but *secondary*, and is scoped as a **single-purpose appliance** — one +instance per trust domain (one team / one purpose), **not** a shared multi-user platform. +"Single-tenant" here means *one trust domain per instance*, not "all humans are equal": any caller +that legitimately reaches an instance is authorized to do whatever that instance permits. + +We decide two things: + +1. **FastSkill is not a security boundary and will not become one.** It handles no tokens, no + identity, no per-user authorization. In shared/enterprise deployments, request authentication + and authorization are enforced **entirely externally** — by a sidecar or reverse proxy that + fronts the port. FastSkill is a lightweight tool; owning auth would contradict that. If a future + requirement needs multiple distinct users with *different* permissions against one instance, + that is a different product and this ADR does not cover it. + +2. **`serve` is read-only by default; mutation is opt-in via `--enable-write`.** With no flag, only + read endpoints are mounted (list/get skills, `search`, `resolve`, `status`, dashboard, registry + browse, manifest reads). `--enable-write` enables **all** state-changing operations in one + switch: create/update/delete skill, `/skills/upgrade`, manifest writes, `/reindex`, and + `/registry/refresh`. The rule is "anything that is not a pure read is gated" — reindex and + refresh are folded in because they are side-effecting (disk, network, embedding-API cost), even + though they are not destructive in the delete sense. Gated routes return **403** with a plain + message directing the operator to restart with `--enable-write`. + +We explicitly **rejected** gating on the *network* (an `--insecure` flag or a non-loopback bind +check). Binding a non-loopback address is the *normal, required* configuration behind a sidecar — +flagging it as "insecure" cries wolf on the correct setup and says nothing about the real risk. The +real risk is not *where* you bind but *what an arbitrary caller can do once connected*, so the +guard belongs on the capability, not the address. The default bind stays `localhost`; binding +elsewhere needs no special flag. + +## Scope + +This ADR covers the **exposure model** of mutating operations. It does not discharge the rest of +the audit. The content-handling and logic findings (SEC-3 zip bomb, SEC-4 symlink deref, SEC-5/6 +traversal, SEC-7 dashboard XSS, SEC-8 weak content scan, and all correctness bugs) are orthogonal — +they trigger for a legitimate caller, and most run in the **CLI** with no server involved. They are +fixed independently. + +The write-gate principle applies to **any** surface that mutates state, not just HTTP. The MCP +server (`fastskill mcp`, kept separate from `serve` by design) currently exposes **no** mutating +tools (`ToolCallingService` returns an empty tool list — see spec 002 PARTIAL-4), so there is no +gate to build there today; if it ever exposes writes, the same read-only-by-default rule applies. + +## Consequences + +- **SEC-1 and SEC-2 are downgraded.** Destructive endpoints are not mounted unless the operator + passes `--enable-write`. Reaching them unauthenticated now requires the operator to have *both* + enabled writes *and* exposed the port with no fronting sidecar — a deliberate double opt-out, not + a silent default. This is an in-app, verifiable control and needs no token machinery. +- **A read-only exposed instance still discloses skill data** (and is subject to SEC-7 dashboard + XSS). That residual is the operator's call when they expose the port; it is not a mutation risk. +- The `--enable-write` default-read-only behavior is a **breaking change** to the current `serve` + surface (today all routes are always mounted) and must be documented in the serve reference, + which currently only says "use a reverse proxy." +- No `FASTSKILL_API_TOKEN`, no `--insecure`, no bind-address policing — the app stays thin. + +## Considered alternatives + +- *In-app auth (identity + per-user authZ)* — rejected: fastskill is single-tenant tooling; + duplicates what the edge proxy already does and adds session/secret-management surface. +- *Optional shared-secret token as an in-app backstop* — considered and rejected: even an optional + token drags token handling into a tool whose whole value is being lightweight. Shared-deployment + security is the sidecar's job. +- *Gate on the network (`--insecure` / refuse non-loopback)* — rejected: binding non-loopback is + the correct behavior behind a sidecar, so a "danger" flag on it is a false signal; it also fails + to protect a non-loopback bind that *is* legitimately fronted. Gating the capability is both + safer and more honest. +- *Two-tier write flags (ordinary writes vs. destructive delete/upgrade)* — rejected: a permission + matrix is more surface than a lightweight tool warrants; one boolean the operator can reason + about is better. diff --git a/docs/adr/0004-bare-version-is-exact.md b/docs/adr/0004-bare-version-is-exact.md new file mode 100644 index 0000000..336120f --- /dev/null +++ b/docs/adr/0004-bare-version-is-exact.md @@ -0,0 +1,37 @@ +# A bare version constraint means an exact pin, not caret + +## Status + +accepted + +## Context & decision + +A Manifest dependency's **version constraint** filters which candidate versions may be selected +during resolution (`resolver.rs`, `constraint.satisfies(candidate)`).

The builder chain +(`server.rs:343-355`) adds CORS, compression, and a fallback but never an authentication +middleware. Handler bodies carry empty `// Check permissions (write access required)` comments +(`skills.rs:73,102,142`) that were never implemented. + +**Failure scenario:** any client that can reach the port can call +`DELETE /api/v1/skills/{id}`, which runs `tokio::fs::remove_dir_all` on the skill directory +(`skills.rs:~223`), or rewrite `skill-project.toml` through the manifest endpoints. Default bind +is `localhost` (safe), but `--host 0.0.0.0` (`commands/serve.rs:36`) is fully supported and +exposes all of this to the network with zero credentials. + +**Deployment context:** **as-is this is Critical** — in the current code every destructive route is +mounted with no auth, so a fresh `serve` (or any deploy before WRITE-GATE lands) is fully exposed. +Per [ADR-0003](../docs/adr/0003-serve-trust-boundary-and-edge-auth.md), fastskill is deliberately not +a security boundary; shared-deployment auth is an external sidecar's job. Once WRITE-GATE ships, +destructive routes are unmounted-by-default and this drops to **Low/Medium**, with residual +**Critical** only when the operator enables writes *and* exposes the port with no fronting sidecar. + +**Recommended approach:** implement **WRITE-GATE** (see the dedicated section below for the concrete +route-split + flag-threading plan); do **not** add in-app tokens or bind policing. Independently, +remove the misleading empty `// Check permissions` comments so the code doesn't imply an auth check +that will never exist. + +**Interim workaround:** run `serve` on `localhost` (the default) and never expose the port without an +authenticating reverse proxy in front; don't enable CORS `allowed_origins` for untrusted sites. + +--- + +### SEC-2 — Unauthenticated remote trigger of `fastskill update` subprocess — **Critical (as-is)** → **Low/Medium** once WRITE-GATE ships (route unmounted by default; residual Critical only if writes enabled *and* port exposed without a sidecar) + +**Where:** `crates/fastskill-core/src/http/handlers/skills.rs:241-282`. + +`upgrade_skills` shells out to the server's own binary: +`Command::new(current_exe).arg("update").arg(id)`, where `id` is the request-body `skillId` +filtered only for empty/`"all"` (`skills.rs:246-248`).

Independently — and this holds even for an authorized caller — in `upgrade_skills` +(`skills.rs:241-282`) validate `filter_id` before spawning: call +`state.service.skill_manager().list_skills()` (the handler already has `state`) and reject with +`HttpError::BadRequest` if the id is not a known dependency. Then build the command as +`cmd.arg("update"); cmd.arg("--"); cmd.arg(id);` so a validated id can never be read as a flag +(defense in depth; `Command` uses no shell). + +**Interim workaround:** run `serve` read-only (don't pass `--enable-write`) so the route is absent; +if writes are needed, keep the port behind an auth proxy that blocks `/skills/upgrade`. + +--- + +### SEC-3 — ZIP bomb / decompression DoS: no size, ratio, or entry-count limit — **High** + +**Where:** `crates/fastskill-core/src/storage/zip.rs:48` (loop) and `:134` +(`io::copy(&mut file, &mut outfile)`). + +`extract_to_dir` streams every entry to disk with **no** per-file uncompressed cap, total-size +cap, compression-ratio check, or entry-count cap. The two hooks meant to guard this are empty +stubs: `ZipHandler::validate_package` (`zip.rs:16`) and +`ZipValidator::validate_zip_package` (`validation/zip_validator.rs:20`) both `return Ok(())`. +The registry download path additionally buffers the entire archive into memory as a `Vec` +before writing (`add/sources.rs:~302`). + +**Failure scenario:** a 1 MB zip that inflates to hundreds of GB (or contains millions of tiny +entries) is fed via `fastskill add evil.zip` or a registry source → fills the disk / exhausts +inodes → host DoS. This is the only fully remote-triggerable filesystem issue. + +**Recommended approach:** add a **single fixed ceiling** (no config knob) enforced inside +`extract_to_dir`, grounded in a measurement of 1311 real skills (package size: p99 1.27 MB, max +5.66 MB; largest single file: max 4.0 MB; file count: max 316 — only one skill exceeds 5 MB, none +exceed 10 MB). Define constants sized comfortably above the whole real corpus while still bounding a +bomb: `MAX_TOTAL_UNCOMPRESSED = 50 MiB` (~9× the largest real skill), `MAX_ENTRY_UNCOMPRESSED = 10 MiB` +(~2.5× the largest real file), `MAX_ENTRIES = 10_000` (~30× the busiest real skill), `MAX_RATIO = 100`. +These are a **DoS ceiling** (protect the host), intentionally distinct from the content-validation +limits that define a *valid* skill (`MAX_CONTENT_SIZE = 512_000` in `context_resolver.rs`, the +`SKILL.md` cap in `file_structure.rs`) — cross-reference those so the two regimes read as related, not +contradictory. Reject before the loop if `archive.len() > MAX_ENTRIES`. Inside the loop, use +zip 0.6's `ZipFile::size()` / `compressed_size()`: reject if declared `size()` exceeds the +per-entry cap or `size()/compressed_size() > MAX_RATIO`. Because the declared `size()` can lie, +also enforce the real budget at the `io::copy` (zip.rs:134) — copy through a running counter (or +`Read::take(remaining_budget)`) and fail with `ServiceError::Validation` when the cumulative +uncompressed total would exceed `MAX_TOTAL_UNCOMPRESSED`. Wire the same entry-count/declared-size +pre-flight into the empty `ZipHandler::validate_package` and `ZipValidator::validate_zip_package` +stubs. Separately, cap the in-memory download in `download_registry_package` (`add/sources.rs:302`) +— `repo_client.download()` returns the whole archive as a `Vec` in RAM before writing, so +reject early if `zip_data.len()` exceeds a compressed-download cap (~50 MiB). + +**Interim workaround:** install only from trusted registries/repos; run installs in a container or +under a filesystem quota / `ulimit -f` so a decompression bomb cannot exhaust the disk. + +--- + +### SEC-4 — Symlinks in git/local skill installs are dereferenced (content exfiltration) — **Medium** + +**Where:** `crates/fastskill-cli/src/commands/add/install.rs:216-238` (`copy_dir_recursive`). + +`entry.file_type()` does not follow symlinks, so a symlinked file reports neither dir nor +regular-file and falls into the `else` branch, where `tokio::fs::copy` (`:232`) **follows** the +link and copies the target's contents. Git-clone and local-folder installs use this path with no +symlink rejection — unlike zip extraction, which does reject symlink entries. + +**Failure scenario:** a malicious git repo or local folder contains `creds -> /etc/passwd` (or +`-> ~/.ssh/id_rsa`); after install the victim's skill-storage copy holds the dereferenced secret +file contents, which can then be re-shared/published. Writes stay inside `dst` (only +`entry.file_name()` is joined), so this is content exfiltration, not an out-of-tree write. + +**Recommended approach:** in `copy_dir_recursive` (`add/install.rs:216-238`), the `entry.file_type()` +from `read_dir` does not follow symlinks, so test it — if `ty.is_symlink()` (or +`std::fs::symlink_metadata(&src_path)` reports a link), reject with +`CliError::Validation("refusing to copy symlink: …")` rather than letting it fall into the +`tokio::fs::copy` branch (which follows the link and copies the target's contents). This matches +the zip extractor's existing symlink-rejection stance. Apply the same guard to any sibling +copy-into-storage path. + +**Interim workaround:** scan untrusted skill directories with `find -type l` before +`fastskill add`, and install only from trusted sources. + +--- + +### SEC-5 — Unvalidated `subdir` from manifest escapes the clone directory — **Medium** + +**Where:** `crates/fastskill-cli/src/utils/install_utils.rs:108-119` +(`temp_dir.path().join(subdir)`); same shape at `add/sources.rs:196-208`. + +`subdir` from `SkillSource::Git { subdir }` is a `PathBuf` taken directly from the (untrusted, +shareable) `skill-project.toml` / lockfile and is `join`ed onto the clone temp dir with no +normalization or containment check. A `..`-laden value escapes the clone; the resulting path is +then passed to `validate_cloned_skill` + `copy_dir_recursive`. + +**Failure scenario:** a committed manifest with `subdir = "../../../../home/user/.ssh"` (or any +directory containing a `SKILL.md`) makes the installer read/copy files from outside the cloned +repo into skill storage. (The `subdir` parsed from a GitHub *tree URL* at `utils.rs:129` is safe +because `Url::parse` collapses `..`; the raw manifest field is the unprotected one.) + +**Recommended approach:** in both `clone_and_find_skill` (`install_utils.rs:108-119`) and +`clone_and_validate_skill` (`add/sources.rs:196-208`), route `subdir` through the existing +`security::path::validate_path_component` per component (or reuse `safe_join(clone_root, subdir)` +from `security/path.rs:155`, which already splits on `/` and validates each part). Reject absolute +paths and `..`. After joining, canonicalize and assert +`joined.canonicalize()?.starts_with(&temp_dir.canonicalize()?)` before the `.exists()` check, so a +`subdir` escaping the clone (via `..` or a symlink) is rejected with `CliError::InvalidSource`. + +**Interim workaround:** clone only from trusted git repos; do not accept untrusted `#subdir=` +fragments / `--subdir` values in manifests you install. + +--- + +### SEC-6 — Unvalidated registry `scope` used in storage path — **Medium** + +**Where:** `crates/fastskill-cli/src/commands/add/sources.rs:251-268` (`parse_registry_scope_id`) +and `:391-393` (`.join(&scope).join(...)`). + +The `scope` half of a `scope/id` registry reference comes from a raw `find('/')` split with no +`validate_path_component` (contrast `registry_index.rs:53-55`, which validates). It is then +`join`ed into the storage path. The skill-ID-mismatch guard (`:380`) constrains only the `id` +component, not `scope`. + +**Failure scenario:** `fastskill add "../evilskill"` → `scope = ".."`, `expected_id = "evilskill"`; +if the registry serves a skill whose validated id is `evilskill`, the storage dir becomes +`skill_storage_path.join("..").join("evilskill")`, writing one directory above the storage root. + +**Verification note:** confirmed, with a scope-narrowing correction — because `scope` is everything +*before the first `/`*, it is a single path segment and **cannot** contain a `/`, so the escape is +limited to exactly **one** parent level (e.g. `..`), not arbitrary-depth traversal. Still a real +out-of-root write; the fix is unchanged. + +**Recommended approach:** run `scope` through `security::path::validate_path_component` — the same +function used at `registry_index.rs:53-55` — either inside `parse_registry_scope_id` (returning +`CliError::Config` on failure) or immediately before the `.join(&scope)` at `add/sources.rs:391`. +This rejects `..`, `/`, `\`, and absolute components, so a crafted `scope` like `../../etc` cannot +redirect the install outside `skill_storage_path`. Validate `expected_id` the same way for symmetry. + +**Interim workaround:** configure only trusted `http-registry` repositories and install skills whose +`scope/id` you control. + +--- + +### SEC-7 — Stored/reflected XSS in the `/dashboard` HTML page — **High** + +**Where:** `crates/fastskill-core/src/http/handlers/status.rs:77` (route `/dashboard`, +`server.rs:294`). + +Skill `name` and `description` are interpolated into HTML via +`format!("
  • {} - {}
    • ", name, desc)` with no escaping. + +**Failure scenario:** a skill whose name/description contains `` (installable +through the unauthenticated manifest/upgrade path in SEC-1/2, or from any marketplace source) +executes JavaScript in the browser of anyone viewing `/dashboard`. + +**Recommended approach:** HTML-escape `name` and `description` before interpolation in +`status::root` (`status.rs:77`). Simplest is a small helper escaping `& < > " '`, applied in the +`.map(...)` closure; or pull in an escaping templating crate (`askama`) / `html-escape` and render +through it. Because the dashboard is an **always-on read route** (served even in read-only mode), +this is the highest-exposure item in the set and must be fixed regardless of WRITE-GATE. + +**Interim workaround:** don't expose `/dashboard` publicly (front it with an auth proxy); vet skill +`name`/`description` for HTML/script content before adding. + +--- + +### SEC-8 — Weak, trivially bypassed content-safety scanning — **Medium** + +**Where:** `crates/fastskill-core/src/validation/content_safety.rs:36-41`. + +The dangerous-pattern check is naive `content.contains(pattern)` against literals like +`"import os"`, `"exec("`, `"sudo"`, `"rm -rf"`. It is trivially bypassed (`exec (` with a space, +`from os import`, `import os` with a double space, any base64/obfuscation) and simultaneously +prone to false positives (any legitimate Python skill importing `os`/`subprocess`, or a +description mentioning "sudo" gets flagged **Critical**). + +**Failure scenario:** a malicious skill evades detection with whitespace variation while a benign +skill is rejected — the check provides little real security and harms usability. + +**Recommended approach:** reframe as **advisory** — downgrade the `contains()` matches in +`add_dangerous_pattern_errors` (`content_safety.rs:36-41`) from `ErrorSeverity::Critical` to a +warning (`with_warning`), so they inform without blocking, and document that this is a heuristic, +not a sandbox. If genuine detection is wanted, tokenize per language instead of substring-matching +— only scan files whose extension marks them as scripts, and match at token boundaries (e.g. +`(?m)^\s*import\s+subprocess\b`, `\bsubprocess\.(Popen|call|run)\b`) rather than bare `contains`. + +**Behavior change (call out in the PR):** this loosens installs — a skill that trips the pattern +list *fails validation today* and will *install with a warning* after the fix. That is intended (the +gate stopped nothing and blocked legitimate shell-automation skills), but it is a change in +observable behavior, not a silent refactor. + +**Required docs deliverable:** state plainly in the security/validation docs that **fastskill does +not vet skill safety** — the pattern scan is an advisory signal, not a sandbox, and untrusted skills +must be run in a sandboxed/containerized environment. Downgrading the severity without this note +would silently weaken a guarantee users may believe they have. + +**Interim workaround:** treat all third-party skills as untrusted code — review scripts manually and +run skills in a sandboxed/containerized environment rather than relying on this validator. + +--- + +### SEC-9 — Predictable shared temp-file paths (local race / symlink) — **Low** + +**Where:** `crates/fastskill-core/src/http/handlers/registry.rs:126` +(`temp_dir().join("fastskill-sources-temp.toml")`) and +`crates/fastskill-core/src/core/repository/client.rs:129` +(`temp_dir().join("fastskill-repo-{name}")`). + +Fixed, world-readable temp paths reused across requests/instances. A local user who pre-creates +or symlinks these paths can influence source resolution or cause cross-request interference. + +**Recommended approach:** replace both fixed paths with unique per-operation dirs via `tempfile` +(already a dependency). At `registry.rs:126` use `tempfile::Builder::new().prefix("fastskill-sources-") +.tempdir()?` and build the sources file inside it, keeping the `TempDir` alive for the manager's +lifetime; likewise at `repository/client.rs:129` swap the predictable `fastskill-repo-{name}` path +for a `TempDir`. This also removes the cross-run collision/race. + +**Interim workaround:** run on a single-user host, or set `TMPDIR` to a private `0700` per-user dir +so the predictable filenames can't be pre-created or read by others. + +--- + +### SEC-10 — CORS `allow_credentials(true)` with an unguarded origin list — **REFUTED (verification pass)** → config-hygiene nit only + +**Where:** `crates/fastskill-core/src/http/server.rs:116-121`. + +Original claim: `.allow_credentials(true)` with no guard against a `"*"` entry in `allowed_origins` is +an exploitable CORS foot-gun. **Verification refuted the exploitability.** It is factually true that +nothing rejects `"*"`, but the dangerous tower-http combination is `AllowOrigin::any()` + credentials +(which *panics at construction*), and that variant is never used here. A literal `"*"` string placed +in an `AllowOrigin::list` is compared as an *exact* origin value — it only matches a request whose +`Origin` header is literally `*` (browsers never send that), so it does **not** reflect arbitrary +origins. A misconfigured `allowed_origins = ["*"]` yields non-functional CORS (browsers reject `*` + +credentials), not a credentialed cross-origin bypass. + +**Disposition:** not a vulnerability. At most, optionally reject/warn on a `"*"` entry as config +hygiene so the misconfiguration fails loudly instead of silently not working. No security fix needed. + +--- + +### SEC-11 — `git clone` runs with no `--` and no protocol allowlist (transport RCE / local-file access) — **High** *(coverage pass: storage/git.rs)* + +**Where:** `crates/fastskill-core/src/storage/git.rs:342-388` (`clone_repository`). + +The clone argv is built as `["clone","--depth=1","--quiet",(--branch,ref)?,"--single-branch", +"--no-tags", url, dest]` — **no `--` end-of-options separator** and **no restriction on git transport +protocols** (no `-c protocol.ext.allow=never` / `-c protocol.file.allow=never` / `GIT_ALLOW_PROTOCOL`). +`clone_repository` is a **public, exported** fastskill-core API that does zero URL validation itself. + +**Failure scenario:** a caller (or a registry/marketplace-sourced skill URL) passing +`ext::sh -c ''` gets **arbitrary command execution** during clone; `file:///…` gives local-path +read/exfil. **Mitigation nuance:** the CLI funnels URLs through `parse_git_url` → `Url::parse` +(`utils.rs:106`), which rejects the space-containing `ext::` form and re-serializes so the URL can't +start with `-` — so the *CLI* path is largely shielded, but **library consumers and `file://` are +not**. Also (Low, same file): the full URL and raw git stderr are logged/emitted (`git.rs:364,395`), +leaking any `user:token@host` credentials embedded in a URL. + +**Recommended approach:** in `clone_repository` itself (not just callers), insert `--` before the +positional `url`/`dest`, and pass `-c protocol.ext.allow=never -c protocol.file.allow=never` (plus an +allowlist of `https`/`ssh`/`git` as desired). Redact credentials from the logged URL. Do this in the +core function so it holds regardless of caller. + +**Interim workaround:** only clone from trusted `https`/`ssh` URLs; never pass a user-supplied string +to `clone_repository` from library code without your own scheme validation. + +--- + +### SEC-12 — `git checkout` flag injection from a URL-derived branch/ref — **Medium** *(coverage pass: storage/git.rs)* + +**Where:** `crates/fastskill-core/src/storage/git.rs:438-462` (`checkout_branch_or_tag`). + +`let args = vec!["checkout", ref_name];` puts `ref_name` as a positional with **no `--`**. `ref_name` +is `branch.or(tag)`, and `branch` can derive from an attacker-controllable GitHub tree-URL path +segment (`utils.rs:127`, `path_segments[3]`) — e.g. `github.com/o/r/tree/--foo`. A ref beginning with +`-` is parsed by git as a flag (flag injection into `git checkout`). + +**Failure scenario:** a crafted tree URL yields a `--`-prefixed ref that git interprets as an option +rather than a branch name. **Recommended approach:** `vec!["checkout", "--", ref_name]`. +**Interim workaround:** don't install from untrusted GitHub tree URLs. + +--- + +**Confirmed NOT vulnerable** (checked and cleared, recorded to prevent re-investigation): +`serve_index_file` path traversal is properly mitigated (`registry.rs` canonicalize + +`starts_with`); no SSRF — all outbound fetches use server-side config URLs, never request bodies; +TLS verification is on everywhere (no `danger_accept_invalid_*`); auth tokens/API keys are only +placed in outbound `Authorization` headers and are not logged; `SkillId::new` rejects `/` and +non-`[alnum-_]` chars, blocking id-based traversal; `git clone` URLs pass through `Url::parse`, +preventing argument-injection via `-`/`ext::`. + +--- + +### WRITE-GATE — read-only `serve` by default; mutations behind `--enable-write` (from ADR-0003) + +This is the single in-app control the security model relies on. It is not a "found vulnerability" +but the app-side commitment that downgrades SEC-1/SEC-2. Deliberately **no** tokens and **no** +bind/network policing — the gate is on the capability. + +**Where:** `crates/fastskill-cli/src/commands/serve.rs` (add `--enable-write` flag); +`crates/fastskill-core/src/http/server.rs:228-299` (conditionally mount mutating routes); +handlers behind it in `skills.rs`, `manifest.rs`, `reindex.rs`, `registry.rs`. + +**Behavior:** +- Default (`fastskill serve`): mount **read** routes only — list/get skills, `POST /search`, + `POST /resolve`, `/status`, dashboard, registry browse, manifest reads. +- `--enable-write`: additionally mount **all** state-changing routes in one switch — + `POST /skills` (create), `PUT`/`DELETE /skills/{id}` (update/delete), `/skills/upgrade`, manifest + writes (`POST/PUT/DELETE`), `/reindex`, `/registry/refresh`. Rule: "not a pure read → gated" + (reindex/refresh included because they are side-effecting: disk, network, embedding-API cost). + `create`/`update` are gated here per PARTIAL-1 (now implement, not remove). +- Gated routes when write is disabled return **403** with a plain message pointing at + `--enable-write` (discoverable, not a mystery 404). +- Default bind stays `localhost`; binding non-loopback needs no special flag (it is the correct + configuration behind a sidecar). + +**Recommended implementation:** add an `enable-write` `ArgSpec` (`ArgKind::Flag`, default `false`) to +`ServeArgs::command_spec()` + a field in `from_arg_value_map`, thread it through `execute_serve` → +`FastSkillServer` (store on the struct, leave `AppState` untouched) → `serve()`. Split the existing +route builders into read vs write sets; in `serve()` only `.merge()` the write set when the flag is +on. Concretely the **read** set is `list_skills`/`get_skill`, `manifest::get_project`, +`list_manifest_skills`, `search`, `resolve`, `status`, the GET registry + index routes, and the +dashboard/UI fallback; the **write** set is `POST /skills` (create), `PUT`/`DELETE /skills/{id}`, +`/skills/upgrade`, `/reindex` + `/reindex/{id}`, `/registry/refresh`, and the manifest +`add`/`update`/`remove` mutators (`create`/`update` implemented + gated per PARTIAL-1). **Always** +register the write paths and wrap them in an +`axum::middleware::from_fn` (or `from_fn_with_state`) that, when the flag is off, short-circuits with +`(StatusCode::FORBIDDEN, Json(ApiResponse::error("write operations disabled; start server with --enable-write")))`. +Do **not** use conditional `.merge()` to drop the routes — that yields a bare 404/405 and defeats the +discoverability the 403 exists for (see Behavior above). The write paths appearing in the route table +even when disabled (returning 403) is intentional and more honest, not a leak. + +**Note:** this is a **breaking change** to the current `serve` surface (today all routes are always +mounted). Update `webdocs/cli-reference/serve-command.mdx`, whose "Authentication Model" section +currently only says "use a reverse proxy" and shows `--host 0.0.0.0` with no mention of write-gating. + +--- + +## 2. Correctness bugs + +### BUG-1 — Version-bump wipes `[metadata].id` and `[tool]` sections (data loss) — **High** + +**Where:** `crates/fastskill-core/src/core/version_bump.rs:82-124`. + +`update_skill_version` deserializes into a local `SkillProjectToml`/`SkillProjectMetadata` that +declares only `version/name/description/author/tags/capabilities/download_url` — **no `id`** and +no `[tool]` — then re-serializes the truncated struct back over the file. Unknown TOML fields are +dropped on the round-trip. + +**Failure scenario:** after `fastskill version bump`, the skill's required `[metadata].id` and any +`[tool.fastskill]` config (eval settings, `skills_directory`, etc.) are gone; the skill then fails +`validate_for_context` for a missing id. Silent data loss. + +**Recommended approach:** replace the deserialize-into-partial-struct → `toml::to_string_pretty` +round-trip with `toml_edit`. Parse `content` into a `toml_edit::DocumentMut`, set only +`doc["metadata"]["version"] = value(new_version.to_string())` (creating the `metadata` table if +absent), and write the document back. This preserves `id`, `[tool]`, comments, and formatting — +strictly cleaner than the serde-`flatten` alternative, which still silently drops any field not +enumerated and forces you to mirror the whole schema. Keep the "file doesn't exist" branch as-is. + +**Interim workaround:** hand-edit the `version` field instead of running `version bump`; or after a +bump, manually re-add the lost `id` and `[tool]` section. + +--- + +### BUG-2 — Caret constraint ignores the semver 0.x rule — **High** + +**Where:** `crates/fastskill-core/src/core/version.rs:163-168`. + +`Caret` is satisfied when `ver >= base && ver.major == base.major`. Semver treats `^0.2.3` as +`>=0.2.3, <0.3.0` and `^0.0.3` as exactly `0.0.3`. The 0.x special-case is missing. + +**Failure scenario:** `foo@^0.2.3` wrongly accepts `0.9.0` — a breaking pre-1.0 change — pulling +an incompatible skill. (Verified: `0.9.0` satisfies because both have major `0`.) + +**Recommended approach (covers BUG-2, BUG-3, BUG-4, BUG-5 — one fix):** delete the hand-rolled +`VersionConstraint` enum, `parse`, and `satisfies`, and back the type with the already-present +`semver` crate. Store a `VersionReq`; implement `parse` as `VersionReq::parse(constraint)` (mapping +errors to `VersionError::InvalidConstraint`) and `satisfies` as +`Ok(req.matches(&Version::parse(version)?))`. `VersionReq` handles all four defects correctly: +caret 0.x (`^0.2.3` → `>=0.2.3,<0.3.0`), strict `<` upper bounds, bare single `<`/`>`, and +two-component `^1.2`/`~1.2` — and it is exactly what `get_latest_version` already uses. + +**⚠ Migration risk (must preserve) — see [ADR-0004](../docs/adr/0004-bare-version-is-exact.md):** +the current parser treats a bare `"1.2.3"` as **Exact** (equality), and per ADR-0004 that is the +intended product semantics (a bare version is an exact pin, not a range). But +`VersionReq::parse("1.2.3")` applies Cargo caret semantics (`>=1.2.3,<2.0.0`), so the migration +**must** normalize a bare `MAJOR.MINOR.PATCH` (no operator, no comma) to `=MAJOR.MINOR.PATCH` before +handing it to `VersionReq::parse` — and that normalization must not be "cleaned up" later (removing +it silently widens every committed bare pin). Also preserve: empty/`"*"` → `VersionReq::STAR`, comma +ranges, and `>=`/`<=`/`<`/`>`/`^`/`~` (all native). Keep the existing `VersionError` variants so +`?`-sites still compile. Add regression tests for bare-pin equality (ADR-0004) and `^0.x`. + +**Interim workaround:** use only the forms the current parser handles correctly — exact `1.2.3`, +`>=x`, `<=x`, or explicit two-sided ranges like `>=1.0.0,<=1.9.9`; avoid `^` on `0.x`, bare `<`/`>`, +and two-component `^1.2`. + +--- + +### BUG-3 — Range upper bound `<` is treated as `<=` — **High** + +**Where:** `crates/fastskill-core/src/core/version.rs:112-116` (parse) and `:200-207` (`satisfies`). + +A strict `<` upper bound is stored as a bare `Range.max` string with no inclusive/exclusive flag, +and `satisfies` always applies `ver <= max` (`version.rs:207`). + +**Failure scenario:** `>=1.0.0,<2.0.0` incorrectly reports `2.0.0` as satisfying. (Verified.) + +**Recommended approach:** subsumed by the unified `semver::VersionReq` fix under **BUG-2** (a real +`VersionReq` distinguishes `<` from `<=` natively). **Interim workaround:** spell the upper bound as +`<=` with the exact predecessor version. + +--- + +### BUG-4 — Bare strict `<` / `>` single constraints fail to parse — **Medium** + +**Where:** `crates/fastskill-core/src/core/version.rs` `parse` (~`:100-147`). + +`<2.0.0` or `>1.0.0` (no comma) match none of the `^ ~ >= <=` branches, fall through to +`VersionReq::parse` (which succeeds), but the resulting `req_str` matches none of the +re-conversion prefixes, so `parse` returns `InvalidConstraint` (`version.rs:147`). + +**Failure scenario:** `fastskill add foo@>1.0.0` errors out as an invalid constraint. + +**Recommended approach:** subsumed by the unified `semver::VersionReq` fix under **BUG-2** (bare +`<`/`>` parse natively). **Interim workaround:** rephrase as a two-sided comma range, e.g. +`>=1.0.1,<=9.9.9` instead of `>1.0.0`. + +--- + +### BUG-5 — Two-component caret/tilde constraints always error at match time — **Medium** + +**Where:** `crates/fastskill-core/src/core/version.rs:132-143` (parse) and `:164,171` (satisfies). + +`^1.2` / `~1.2` are stored as `Caret("1.2")` / `Tilde("1.2")`, but `satisfies` then calls +`Version::parse("1.2")`, which fails (needs three components), yielding `ParseError` on every +check. + +**Failure scenario:** the common constraint `^1.2` never matches anything and surfaces a parse +error. + +**Recommended approach:** subsumed by the unified `semver::VersionReq` fix under **BUG-2** +(`^1.2`/`~1.2` are valid `VersionReq` inputs). **Interim workaround:** write the third component, +e.g. `^1.2.0`. + +--- + +### BUG-6 — `topological_sort` can underflow/panic on duplicate `add_skill` — **Low (latent — not currently reachable)** *(was Medium; downgraded in verification)* + +**Where:** `crates/fastskill-core/src/core/dependencies.rs:82-93` (`add_skill`) and `:212` +(Kahn loop `*degree -= 1`). + +`add_skill` overwrites the forward graph but **appends** to `reverse_graph`, so re-adding an +existing skill leaves duplicate reverse edges while `in_degree` is computed from the deduped +forward graph. The decrement can then run more times than the initial degree, underflowing +`usize` (debug panic / release wrap). + +**Failure scenario:** rebuilding a graph entry for an existing skill panics during install-order +computation. + +**Verification note (reachability corrected):** the code defect is real, but the "panics during +install-order computation" scenario is **not currently reachable** — `DependencyGraph::build_graph` +has **no production callers**, `add_skill` is only called by `build_graph` and by unit tests (none of +which add a duplicate id), and the `topological_sort` used in production is a *different* struct +(`DependencyResolver`, see PARTIAL-8). So this is a latent defect that only bites a future caller that +passes a duplicate `skill_id`. Fix it (cheap) as hardening, but it is not an active bug — hence the +downgrade to Low. (`DependencyGraph` being entirely unused in production is itself worth a dead-code +review.) + +**Recommended approach:** in `add_skill`, before the forward-graph `insert` overwrites an existing +entry, remove `skill_id` from each old dependency's `reverse_graph[dep]` vec, then insert and +rebuild the reverse edges (de-duping per target). As defense, change `*degree -= 1` (dependencies.rs:212) +to `*degree = degree.saturating_sub(1)` so a stray duplicate edge can't panic via usize underflow. + +**Interim workaround:** build the graph once via `DependencyGraph::build_graph` from a de-duplicated +skill list; never call `add_skill` twice for the same id. + +--- + +### BUG-7 — Git-diff skill detection uses naive string prefix — **Medium** + +**Where:** `crates/fastskill-core/src/core/change_detection.rs:42,47`. + +`path_str.starts_with(&skills_dir_str)` is a raw string prefix; the `.or_else` fallback strips the +prefix without the trailing `/`. With `skills_dir = "skills"`, a changed file under +`skills-extra/foo` passes and is parsed as skill id `-extra`. On Windows, backslash-vs-slash means +the prefix never matches at all. + +**Failure scenario:** unrelated sibling directories sharing a prefix get flagged as changed +skills. + +**Recommended approach:** use `Path::new(path_str).strip_prefix(skills_dir)` (which strips on whole +path components, not raw bytes) and take the first remaining `Component` as the skill id, skipping +the line when `strip_prefix` returns `Err`. This also removes the fragile manual `/`-trimming +`.or_else` chain. + +**Interim workaround:** avoid sibling directories that share the skills-dir name as a prefix (e.g. no +`skills-archive/` next to `skills/`). + +--- + +### BUG-8 — Atomic-write truncate-on-open races ahead of the advisory lock (corruption) — **Medium** + +**Where:** `crates/fastskill-core/src/utils.rs:36-64` (the shared `atomic_write` helper). + +**Corrected mechanism (an earlier draft of this finding described it wrongly):** `tmp_path` is +*deterministic* (`path + ".tmp"`), shared by all writers to the same target, and +`try_lock_exclusive` *does* mutually exclude — so "the lock is on an unstable path" is **not** the +bug. The real defect is that `OpenOptions::truncate(true).open(&tmp_path)` truncates the tmp file +**at open time, before the lock is checked**. fs2 advisory locks are cooperative, so a second writer +arriving while the first holds the lock still truncates the first writer's tmp (via its own +`open(truncate)`) — and with `unlock()` happening *before* `fs::rename()` (utils.rs:61 then :64), +the first writer can then rename a truncated/empty file over the target. + +**Failure scenario:** two processes running `save_to_file` on the same `skills.lock` concurrently: +writer B's `open(truncate)` blows away writer A's synced tmp between A's `sync_all` and A's `rename`, +so A publishes an empty/corrupt lock. + +**Recommended approach:** drop the advisory lock and use a **per-writer unique tmp** (random suffix) ++ atomic rename — the standard robust pattern (`tempfile::NamedTempFile::persist`). Each writer owns +its tmp, so no writer can truncate another's; `fs::rename` (atomic on POSIX) then publishes a +*complete* file. This yields clean **last-writer-wins** semantics — correct for a byte-level writer, +since the file is always some writer's full content, never truncated. Do **not** try to fix the +existing lock: getting fs2 flock right (lock before open, no truncate-race, hold across rename, +cross-platform) is fiddly and buys only a fail-fast "another writer active" error, which is of +dubious value. If true concurrent-writer coordination is ever needed (e.g. two `install` runs), put +a project-level lock around the whole resolve+write, not inside `atomic_write`. + +**Interim workaround:** serialize `fastskill` invocations that mutate the same lock/registry file; +don't run two writers against the same target concurrently. + +--- + +### BUG-9 — Reconciliation ignores the project version constraint — **Low** + +**Where:** `crates/fastskill-core/src/core/reconciliation.rs:83,95-105`. + +A skill present in the project but absent from the lock is unconditionally `Ok`, and the +`project_deps` constraint is never evaluated; `missing` entries always emit `version: None` +despite the constraint being available. + +**Failure scenario:** an installed skill that violates its declared project constraint reconciles +as `Ok`. + +**Recommended approach:** in the `is_in_project` branch of `build_reconciliation_report`, when a +constraint string is present (`project_deps.get(&skill_id)`), parse it and call `.satisfies(&skill.version)` +(using the BUG-2 `VersionReq`-backed type); if it doesn't satisfy, mark +`ReconciliationStatus::Mismatch` and record a `VersionMismatch`. Keep the lock-equality check as an +additional signal, but let the constraint check drive `Mismatch`. + +**Interim workaround:** keep `skills.lock` regenerated in sync with the project constraints, and +manually verify installed versions against declared ranges. + +--- + +### BUG-10 — String version sort picks the wrong version — **Medium** *(was Low; escalated in verification)* + +**Where:** `crates/fastskill-core/src/core/registry/client.rs:154-164` (`get_versions`, `// TODO: Use +semver`) **and — found in verification — `crates/fastskill-cli/src/commands/add/sources.rs:271-294` +(`resolve_registry_version`).** + +Reverse **string** comparison orders multi-digit versions wrong (`"1.9.0"` sorts newer than +`"1.10.0"`). `get_versions` alone would be display-only (`get_latest_version` re-sorts with `semver`). +**But verification found a second site that is *not* cosmetic:** `resolve_registry_version` does its +own `sorted.sort()` (lexical) then `.last()` to choose the version **to install** — so with versions +`1.9.0` and `1.10.0` present it installs `1.9.0`, the wrong one. That is a functional resolution bug, +which is why this is Medium, not Low. + +**Recommended approach:** fix **both** sites to sort by `semver::Version` (mirroring +`get_latest_version`), e.g. `sort_by(|a, b| Version::parse(b).ok().cmp(&Version::parse(a).ok()))`, +unparseable strings lowest; remove the stale `TODO`. **Interim workaround:** pin the exact version in +the manifest (per ADR-0004, a bare version is an exact match) so resolution doesn't rank a candidate +set. + +--- + +### BUG-11 — Directory-only zip entries written as empty files — **Low (cosmetic)** + +**Where:** `crates/fastskill-core/src/storage/zip.rs:88`. + +`normalized_entry_name.ends_with("/")` is always `false` after `PathBuf` normalization (no +trailing-slash component), so the directory branch (`:99-107`) is dead and directory-only entries +are created as empty files. No security impact. + +**Recommended approach:** determine directory-ness from the source before normalizing — use the zip +crate's `ZipFile::is_dir()`, or check the raw `entry_name.ends_with('/')` captured at zip.rs:53, and +bind that into `path_is_directory` instead of testing the normalized `PathBuf`. **Interim workaround:** +re-package archives so directories are implied by file paths (no standalone dir entries); parent dirs +are still created when files are written. + +--- + +### BUG-12 — Structured `CloneFailed` error is dead code; clone failures lose URL context — **Low** *(coverage pass: storage/git.rs)* + +**Where:** `crates/fastskill-core/src/storage/git.rs:390-398`. + +`execute_git_command_with_retry` already returns `Err` on any non-zero exit (git.rs:254/272), so on +the `Ok` path `output.exit_code` is always 0. The `if output.exit_code != 0 { return +Err(CloneFailed{url,stderr}) }` block is therefore **unreachable**, and the structured +`CloneFailed{url,stderr}` error is never produced — clone failures surface as the generic +`"Git command failed: {stderr}"`, losing the URL/structured context. (Related Low: the git-version +cache only stores `Ok`, so a too-old/parse-fail git re-runs `git --version` on every clone — +git.rs:86-136.) + +**Recommended approach:** drop the dead exit-code branch and instead map the `Err` from +`execute_git_command_with_retry` into `CloneFailed{url,stderr}` so the structured error actually fires. + +--- + +### BUG-13 — Event history keeps the *oldest* events and silently drops all new ones — **Medium** *(coverage pass: events/event_bus.rs)* + +**Where:** `crates/fastskill-core/src/events/event_bus.rs:165-170`. + +The history buffer does `history.push(event)` then `if history.len() > max { history.truncate(max) }`. +`Vec::truncate(n)` retains the **first** `n` elements — so once history reaches `max_history_size` +(100), every subsequent push is immediately discarded (the just-appended newest entry is the one +thrown away). `get_event_history()` returns the first 100 events ever published and never reflects +recent activity. + +**Failure scenario:** after 100 events, any `optimize`/debug tooling reading history sees a +permanently frozen, stale snapshot. **Recommended approach:** use a `VecDeque` with +`pop_front()` when over capacity (or `history.remove(0)`) — a real ring buffer that drops the oldest. + +--- + +### BUG-14 — Event dispatch holds a read-lock across every handler `await` (deadlock / serialization) — **Medium (suspected)** *(coverage pass: events/event_bus.rs)* + +**Where:** `crates/fastskill-core/src/events/event_bus.rs:189-215` (`notify_handlers`). + +`notify_handlers` holds `handlers.read().await` for the whole loop while awaiting each +`handler.handle_event(...).await`. Tokio's `RwLock` is write-preferring and non-reentrant, so a +handler body that calls `register_handler`/`unregister_handler` (which take `write().await`) — or a +concurrent registration queued while a long handler awaits — **stalls/deadlocks**. It also serializes +all handler execution under a lock held across arbitrary user async code. + +**Failure scenario:** a custom `EventHandler` that (re)subscribes in response to an event deadlocks the +bus. **Recommended approach:** clone the handler list (they are `Arc`s) under a short read-lock, drop +the guard, then await the handlers outside the lock.

The *add-from-source* part ("same source types in the browser": +local/git/zip-url/registry) maps to the **install** path — a separate UI action from +create-from-scratch. Recorded here as the decision to build; the design lives in that spec. + +**Interim workaround:** manage skills via the CLI (`fastskill add`/`update`) until the UI ships. + +--- + +### PARTIAL-2 — `eval run` flags `--no-fail`, `--trials`, `--ci`, `--threshold` are unreachable — **High** + +**Where:** `crates/fastskill-cli/src/commands/eval/run.rs:56-67,85-159,224-227`. + +`RunArgs` documents these four flags and the execute logic fully uses them (`:290-304,564-568,645`), +but `command_spec()` registers none of them and `from_arg_value_map` hardcodes +`no_fail:false, trials:None, ci:false, threshold:None`. They cannot be passed from the CLI, so +CI-mode gating and per-run trial/threshold overrides are dead. (`eval score` registers `--no-fail` +correctly, confirming the omission is accidental.) + +**Decision: IMPLEMENT (wire through).** Add each `ArgSpec` in `command_spec()` (`Flag` for +`no-fail`/`ci`, `Option` `U32`/`F64` for `trials`/`threshold`) and read them in `from_arg_value_map` +— `eval score` (`score.rs:75-83,114`) already demonstrates the exact pattern for `no-fail`. +Low-risk; the consuming logic already exists. + +**Interim workaround:** none — the flags are unreachable from the CLI until wired (scripts must rely +on defaults). + +--- + +### PARTIAL-3 — ZIP-URL install is unimplemented but the repo type is configurable — **Medium** + +**Where:** `crates/fastskill-cli/src/utils/install_utils.rs:293-303`. + +`install_from_zip_url` returns `CliError::Config("ZIP URL installation not yet implemented")`, +yet `RepositoryType::ZipUrl` is fully parseable and config-convertible (`config.rs:64,80-82`). A +user can configure a `zip_url` repository that then fails only at install time. + +**Decision: IMPLEMENT (product decision — wanted capability).** Note the scope: `zip-url` is a +**remote HTTP source** — a URL hosting skill zip archives (+ a `marketplace.json` catalog), e.g. a +GitHub release asset / S3 / CDN. It is distinct from the `local` source type (a local folder as a +repository), which already works. `RepositoryType::ZipUrl` is first-class everywhere else — the +sources manager already loads `marketplace.json` from a ZipUrl (`manager.rs:161`) — so only the +*install* leg is missing; rejecting the type at parse time would break discovery. Have +`install_from_zip_url` download the archive and route it through the existing safe extractor +(`storage/zip.rs` + `zip_validator.rs`, with the SEC-3 size caps). + +**Interim workaround:** install ZipUrl skills out-of-band — download and unzip manually into the +skills dir, or use a `git`/`local` source instead. + +--- + +### PARTIAL-4 — Tool-calling subsystem always reports zero tools — **Medium** + +**Where:** `crates/fastskill-core/src/core/tool_calling.rs:26-45`. + +`ToolCallingServiceImpl::get_available_tools` always returns `Ok(vec![])`; `ToolResult` / +`AvailableTool` and the trait are scaffolding (`// Add other fields/methods as needed`). The +entire subsystem is a placeholder. + +**Decision: REMOVE (dead surface).** Confirmed orphaned: the only references are a crate-doc example +(`lib.rs:44`), the `Service::tool_service()` accessor (`service.rs:427`), and the re-exports +(`lib.rs:75`, `core/mod.rs:110`) — **no code consumes `get_available_tools()`**. It is **not** the MCP +seam: fastskill has no MCP server of its own (no `ServerCapabilities`/`tools/call` anywhere); the +`mcp` command is cli-framework's built-in, which exposes registered *commands* as tools, not this +`ToolCallingService`. So removing it does not touch the `mcp` capability in CONTEXT.md. **Removal +scope:** delete `core/tool_calling.rs`, the `tool_service()` accessor, both re-exports, and the +crate-doc example. Reintroduce behind a concrete spec if skills-as-tools is ever actually built. +**Interim workaround:** n/a (no user-visible behavior today). + +--- + +### PARTIAL-5 — Runtime "discovery" is a hardcoded list, not real detection — **Medium** + +**Where:** `crates/fastskill-cli/src/runtime_selector.rs:51,58-64`. + +`RUNNABLE_AGENTS` is a static `["codex","claude","gemini","opencode","agent","aikit"]`. `--all` +returns this constant regardless of what is installed, despite docs claiming "runtimes discovered +by aikit." The `EmptyRuntimeSet` error branch (`:78-84`) is therefore dead (the list is never +empty). + +**Decision: IMPLEMENT real detection.** aikit-sdk already ships the discovery API this needs — +`get_installed_agents() -> Vec` (probes each binary via `is_agent_available` → `--version`). +The code is already structured for it: `resolve_with_discovery` takes a discovery closure, and only +the public `resolve_runtime_selection` hardcodes `RUNNABLE_AGENTS`. Swap that closure to call +`get_installed_agents()`, which makes `--all` reflect what's installed and makes the `EmptyRuntimeSet` +branch reachable; the `mock_runtimes`/`mock_empty` test seams stay intact. + +**Interim workaround:** pass explicit runtime ids (e.g. `--runtime claude`) instead of `--all` so you +only target agents you know are installed. + +--- + +### PARTIAL-6 — `reindex` HTTP endpoints are no-ops returning mock responses — **Medium** + +**Where:** `crates/fastskill-core/src/http/handlers/reindex.rs:13-47`. + +`POST /reindex` and `POST /reindex/{id}` return mock success without doing anything. Currently +harmless, but they lie to callers (`reindex_all` reports `total_processed: 0`; `reindex_skill` +reports a fake `success_count: 1`). + +**Decision: IMPLEMENT, write-gated.** The real path exists and is proven: CLI +`commands::reindex::execute_reindex(service, ReindexArgs{…})`, already used by +`utils/reindex_utils::maybe_auto_reindex`. Call it against `state.service` and return the true +counts. Reindex mutates the embedding index, so it sits behind `--enable-write` (WRITE-GATE); until +wired, return **501** rather than a mock **200**. **Interim workaround:** run `fastskill reindex` from +the CLI instead of the HTTP endpoint. + +--- + +### PARTIAL-7 — `eval` `--format grid` and `--format xml` silently fall back to table — **Low/Medium** + +**Where:** `eval/run.rs:601-641`, `eval/score.rs:122,260`, `eval/report.rs:108,124`, +`eval/validate.rs`. + +All four eval commands advertise and parse `--format table|json|grid|xml`, but their output code +only branches on `use_json`, so `grid`/`xml` produce identical plain-table output. (Grid/Xml ARE +implemented for `search`/`list`/`read`/`analyze`/`registry` via `output/mod.rs`; the eval +omission is a real gap.) + +**Decision: DROP the choices (reject `grid`/`xml` for eval) unless a formatter is actually written.** +Correction from the fix pass: the shared `output/mod.rs` formatters are **not** generic — they take +domain-specific row types (search/list/show results), none of which accept an eval `RunSummary`, so +"route eval through the shared formatter" is not free reuse; it requires writing eval-specific +grid/xml emitters. Cheapest honest fix: make `validate_format_args` reject `grid`/`xml` for eval and +drop them from the help text; implement eval grid/xml only if that output is genuinely wanted. + +**Interim workaround:** use `--format json` (fully implemented) for machine-readable eval output; +`table` for humans. + +--- + +### PARTIAL-8 — Dependency resolution / sort naming is misleading — **Low** + +**Where:** `crates/fastskill-core/src/core/resolver.rs:264-300`; +`dependency_resolver.rs:125-140,170-174`. + +`PackageResolver::resolve_dependencies_recursive` resolves only one level despite its name — it +never fetches resolved skills' transitive deps (real traversal lives in `DependencyResolver`). +`DependencyResolver::topological_sort` (`:170-174`) is a documented no-op passthrough relying on +BFS order. Cycle detection (`:125-140`) conflates diamonds with cycles, emitting a spurious +"Circular dependency detected" warning for shared deps (A→B, A→C, B→D, C→D). + +**Decision: RENAME + FIX the false warning (priority is the warning).** Rename +`resolve_dependencies_recursive` → `resolve_dependency_list` (or make it genuinely recurse). Replace +the global-`visited_skills` cycle heuristic with path-based detection: keep a separate in-progress / +ancestor set and only warn on a back-edge to an ancestor, so legitimate diamonds stop emitting +"Circular dependency detected." `topological_sort` (`:170-174`) is an admitted no-op — either delete +it or make it enforce the BFS ordering it claims. + +**Interim workaround:** ignore the spurious "circular dependency" warning when your graph has shared +(diamond) dependencies — resolution/dedup itself is correct; only the warning is wrong. + +--- + +### PARTIAL-9 — Misc unfinished spots — **Low** + +- `core/manifest.rs:579-580` (the `to_skill_entries` hardcode; `handlers/manifest.rs:205-206` is just + the `#[serde]` field) — **not a bug (correction):** a bare `"1.0.0"` version-string dependency + legitimately has no group/editable metadata, so `groups=[]`/`editable=false` is correct (the `Inline` + arm at :582-588 reads real values). *Approach:* keep the behavior, replace the `// TODO` with a + comment noting it's intentional. +- `config.rs:161-165` — `create_service_config`'s `_sources_path_override` is a dead parameter. + *Approach:* either wire it into the skills-dir precedence chain it documents, or remove it from the + signature and callers. (Low risk either way; removing is simplest.) +- `core/routing.rs:13,24,36,90,118` — **not scaffolding (correction):** `RoutingServiceImpl::find_relevant_skills` + is fully implemented; the cited lines are only stale `// Add other fields/methods as needed` + comments. *Approach:* delete the stale comments. (The relevance heuristic itself is a separate, + deliberate design choice, not an unfinished stub.) +- `validation/standard_validator.rs:203-227` — directory-structure validation false-positives on any + description mentioning "scripts"/"references". *Approach:* replace the `description.contains(...)` + heuristic with parsing the frontmatter's actual referenced paths, or drop the check rather than + emit spurious `InvalidDirectoryStructure` errors. + +--- + +### PARTIAL-10 — Hot-reload is a silent no-op that lies when enabled — **High** *(coverage pass: storage/hot_reload.rs)* + +**Where:** `crates/fastskill-core/src/storage/hot_reload.rs` (whole file); wired at +`core/service.rs:344-380`. + +The entire hot-reload subsystem is a non-functional stub: `enable_hot_reloading` ignores its `_paths` +argument and returns `Ok(())`, `disable_hot_reloading` is a no-op, and the `notify` crate (declared as +the optional `hot-reload` feature dep) is **never imported or used**. But it is wired into service +init: when a user sets `config.hot_reload.enabled = true`, the service calls `enable_hot_reloading`, +which returns `Ok(())` — so the user believes hot reload is active and skill edits will be picked up, +while **nothing is watched and no reindex ever fires**. Silently inert, no warning. + +**Decision: IMPLEMENT (product decision — keep the feature).** Build the `notify` watcher: watch the +skills directory, debounce filesystem events, and drive the existing `execute_reindex` path so a +running `serve` picks up skill edits live (no restart / manual reindex). This is a local-dev +convenience for the `serve` loop. Because it triggers reindex (a write-gated operation), it should +only auto-fire when writes are enabled (WRITE-GATE), or be understood as a local-only capability. Until +the watcher is wired, `enable_hot_reloading` must **not** silently return `Ok(())` — return an +error / warn — so a user who enables it isn't misled that it works. + +**Interim workaround:** don't set `hot_reload.enabled = true` (it does nothing); re-run `fastskill +reindex` manually after editing skills. + +--- + +### PARTIAL-11 — skillopt `inspect`/`status` swallow JSON parse errors (corrupt run reads as empty) — **Low** *(coverage pass: skillopt)* + +**Where:** `crates/fastskill-cli/src/commands/skillopt/inspect.rs:143-144` and `status.rs:119`. + +`inspect` does `serde_json::from_slice(...).unwrap_or(Value::Null)` and +`to_string_pretty(...).unwrap_or_default()`; `status` does +`from_slice(&history_bytes).unwrap_or_default()`. A corrupt `patch.json`/`gate_scores.json`/ +`history.json` renders as empty/`null` instead of reporting corruption — and `status` is *inconsistent* +(it correctly surfaces `OPTIMIZE_RUN_DIR_CORRUPT` for `runtime_state.json` at :112 but not for +`history.json`). + +**Decision: surface the error.** Map parse failures to the existing corrupt-run error path rather than +`unwrap_or_default`, so a truncated run reports corruption instead of a misleadingly empty view. +(`skillopt/config.rs` was checked and is clean — no parsed-but-unused options, no stubs.) + +--- + +## Suggested triage order + +The deployment decision (ADR-0003 — fastskill is not a security boundary; read-only by default) +means SEC-1/SEC-2 no longer lead; the WRITE-GATE that downgrades them does, followed by the +content/logic issues the exposure model does nothing for. + +1. **WRITE-GATE** — read-only `serve` by default + `--enable-write`.

Do first. +2. **SEC-11, SEC-12** — `git clone`/`checkout` argument + protocol hardening (add `--`, disable + `ext`/`file` transports). SEC-11 is `ext::` RCE for any library consumer of `clone_repository`; the + CLI is partially shielded but the core fix is cheap and belongs in the function itself. +3. **SEC-3** — the only fully remote-triggerable filesystem DoS; unaffected by the exposure model; + the guard hooks already exist as empty stubs. +4. **BUG-1, BUG-2, BUG-3, BUG-10** — silent data loss and wrong dependency resolution in normal use + (BUG-10 now installs the *wrong version* via string sort, not just mis-displays it). +5. **SEC-4, SEC-5, SEC-6, SEC-7, SEC-8** — install-path content handling and dashboard XSS; all + orthogonal to who is calling, so the exposure model does not cover them. +6. **BUG-13/BUG-14** (event bus: frozen history, lock-across-await deadlock) if the event bus is on a + live path for you. **PARTIAL-10** (hot-reload) until its watcher is built must at least fail loudly + instead of silently returning `Ok(())`. +7. **Feature work** decided during triage (own specs, not bug-fixes): **PARTIAL-1** (browser skill + create/edit, `editable`-only, write-gated), **PARTIAL-3** (install from remote zip-url), + **PARTIAL-10** (hot-reload watcher → reindex). **Remove** decided: **PARTIAL-4** (`tool_calling` + stub) and **BUG-6**'s unused `DependencyGraph`. **PARTIAL-6** (reindex endpoints) → implement + (write-gated) or honest `501`. Remaining Low bugs as capacity allows. + +Out of scope by decision (ADR-0003): in-app authentication, API tokens, and bind-address policing. +Shared-deployment request auth is an external sidecar/proxy concern, not fastskill's. + +--- + +## Method note + +Findings come from a targeted read of the security- and logic-critical modules (zip/path/fs, +HTTP server + handlers, network clients, version/lock/resolve/reconcile logic, CLI/eval/skillopt), +cross-checked against `grep` sweeps for `todo!/unimplemented!/not implemented/placeholder/FIXME` +and `unwrap()/expect()`.

From dc0273c2e490b474da5479f069194d0ce73243c1 Mon Sep 17 00:00:00 2001 From: Alex Oliveira <4482374+aroff@users.noreply.github.com> Date: Tue, 7 Jul 2026 22:58:13 +0000 Subject: [PATCH 2/8] docs(spec-003): resolve O1-O5; reframe as source-oriented skill management Grilling settled spec 003's five open questions and corrected the model: the browser manages skills as install-units (install-from-source / update / remove), NOT form-based content authoring. A Skill is multi-file, so editing SKILL.md via a form is the wrong tool. - O1 (moot): no form create, so no id derivation. - O2: read-only SKILL.md view = escaped raw text, no Markdown->HTML in v1. - O3: lift add/install into fastskill-core (install_from_source), call in-process (no shell-out); update uses the already-core UpdateService. - O4 (moot): no create-from-form. - O5: update = re-fetch from source and overwrite (resembles `fastskill update`), versionless by default. Two resolution models documented: ref/source-based (local/git/zip, versionless) vs version-based (registry, ADR-0004). Version picker is a registry-only future refinement. Reconciled spec 002: PARTIAL-1 back to REMOVE (create_skill/update_skill were never the intended shape); WRITE-GATE write-set now POST /skills/install + POST /skills/update (was upgrade) + DELETE, dropping the form create/field-edit routes; triage order updated.

Rendering authored **Markdown `body`** additionally needs a - safe/ sanitizing renderer (no raw HTML passthrough). -- **Untrusted skills are still not vetted.** Adding from a git/registry/zip source runs the same - content that the CLI would install; per spec 002 SEC-8, fastskill does not sandbox skills. The UI - must not imply that browser-added skills are "safe." -- **No new network exposure.** This feature adds no auth of its own; it relies entirely on WRITE-GATE - + the external-sidecar model (ADR-0003). It does not change the trust boundary. +- **SEC-7 (XSS) is a prerequisite** — the UI renders skill-derived `name`/`description` and (read-only) + `SKILL.md`; all must be HTML-escaped. No raw-HTML Markdown rendering in v1. +- **Untrusted skills are not vetted** (SEC-8): installing from git/registry/zip runs the same content + the CLI would; the UI must not imply browser-installed skills are "safe." +- **Install lifted to core, not shelled out** (O3): avoids a request-body-to-subprocess path, + consistent with the SEC-2 hardening; the update route should likewise stop shelling out. +- **No new trust boundary** — relies entirely on WRITE-GATE + the external-sidecar model (ADR-0003). --- -## Open questions +## Resolved design decisions (from grilling) -- **O1 — id derivation** on create (slug vs explicit; collision handling). Recommend slug-from-name. -- **O2 — Markdown body renderer**: which sanitizing renderer for the `body` preview, and do we render - Markdown at all in v1 or store/edit raw text only? (Leaning raw-text edit + escaped preview in v1.) -- **O3 — Add-from-source endpoint shape**: reuse `POST /manifest/skills` + a follow-up install call, - or a single `POST /skills/install` that does add+resolve+install atomically? (Leaning the latter for - a clean UI action, but it overlaps existing manifest routes — needs a call.) -- **O4 — Resource files on create**: v1 is `SKILL.md`-only. Is a later "upload resources" flow wanted, - or do resource-bearing skills always come via add-from-source? (Assume the latter unless told.) +- **O1 — moot:** no form-based create, so no id-derivation problem; ids come from the source as today. +- **O2 — resolved:** read-only skill detail shows `SKILL.md` as escaped raw text; no Markdown→HTML in + v1 (sanitized renderer required if ever added). +- **O3 — resolved:** lift add/install into a `fastskill-core` service method; the handler calls it + in-process (no shell-out). Update uses the already-core `UpdateService`. +- **O4 — moot:** no create-from-form, so no "resources on create" question; multi-file skills arrive + whole via install-from-source. +- **O5 — resolved:** update = **re-fetch from source and overwrite**, versionless by default + (resembles `fastskill update`). Version selection is a registry-only future refinement, not v1. --- ## Implementation phases -1. **Prerequisites (spec 002):** WRITE-GATE, SEC-7 (XSS escape), and — for add-from-source — SEC-3/4/5/6/11/12 - and PARTIAL-3 (zip-url install). These are audit fixes, tracked in spec 002; this feature builds on them. -2. **Create + Edit endpoints** (`create_skill`/`update_skill`), editable-only constraint, proper status - codes; behind WRITE-GATE. -3. **UI: manage panel** — read-only-mode detection + banner; Create form; Edit form (editable skills - only); Delete/Upgrade already wired. -4. **UI: Add-from-source** — the four source types (needs O3 resolved). -5. **Hot-reload live refresh** (PARTIAL-10) — optional polish; the UI refetch-after-write works without it. +1. **Prerequisites (spec 002):** WRITE-GATE, SEC-7 (XSS escaping), the install-path hardening + (SEC-3/4/5/6/11/12), and PARTIAL-3 (zip-url install). Also **remove** the `create_skill`/`update_skill` + stubs (PARTIAL-1). +2. **Core install seam:** lift add/install into `fastskill-core` (`install_from_source`); refactor + `execute_add` to call it; refactor the update route to call `UpdateService` directly (drop shell-out). +3. **Endpoints:** `POST /skills/install`, `POST /skills/update` (+ keep `DELETE`), all write-gated with + structured results. +4. **UI:** read-only-mode detection + banner; an "Install skill" flow offering the four source types; + per-skill Update + Remove; read-only detail view (escaped `SKILL.md`). +5. **(v2, optional)** registry version picker; sanitized Markdown preview. --- ## Non-goals -- Multi-user authoring, per-user permissions, or any auth beyond WRITE-GATE + external sidecar (ADR-0003). -- Editing skills that are pinned to a remote source (blocked by the editable-only rule). -- Resource/multi-file authoring via `create` in v1 (use add-from-source). -- A REST-CRUD API contract for third-party integrations — this surface exists to back the local UI. +- Form-based skill authoring or `SKILL.md` field editing in the browser (skills are multi-file; author + in an editor, then install-from-source). +- A version picker for ref-based sources (there are no versions to pick). +- Multi-user authoring / per-user permissions / any auth beyond WRITE-GATE + external sidecar (ADR-0003). +- A general REST-CRUD API for third-party integrations — this surface backs the local UI.

HTTP / WRITE-GATE (http/server.rs, handlers/{skills,reindex,status,registry}, cli serve.rs, config.rs): - SEC-1/SEC-2 WRITE-GATE: serve is read-only by default; `--enable-write` opts in. Write routes always registered but wrapped in from_fn_with_state middleware returning 403 ("start server with --enable-write") when disabled. enable_write threaded serve.rs -> FastSkillServer -> AppState. - PARTIAL-1: removed the non-functional create_skill (POST /skills) and update_skill (PUT /skills/{id}) handlers + routes. - SEC-2 hardening: upgrade_skills validates skillId against known skills and passes `--` before the positional id. - SEC-7: HTML-escape skill name/description in the dashboard. - SEC-9: unique tempfile dir for the sources temp file. - SEC-10: reject "*" origin combined with allow_credentials. - PARTIAL-6: reindex endpoints return honest 501 (core can't reach the CLI reindex path) instead of a mock 200; write-gated. - PARTIAL-9: drop dead _sources_path_override param (+ call sites). install paths (add/sources.rs, install_utils.rs, registry/client.rs, repository/client.rs): - SEC-5: validate manifest `subdir` (reject ../absolute, contain in clone). - SEC-6: validate registry `scope` before joining into storage path. - SEC-9: unique tempfile dir for the repo clone. - BUG-10: sort versions by semver at both sites (get_versions + resolve_registry_version) — was installing the wrong version. - PARTIAL-3: implement install_from_zip_url (download + SEC-3-capped extract). removals: - PARTIAL-4: delete the inert tool_calling subsystem (module, re-exports, Service::tool_service, lib doc example).
