OpenHands microagents (`.openhands/microagents/`) + +This is really **three sub-mechanisms** under one directory. I'll split where the model differs. + +### 1a. Repository microagent (`repo.md`) +- **Definition format:** Markdown; YAML frontmatter **optional**. If present, supports an `agent` field (defaults to `CodeActAgent`). No frontmatter → loaded as the repo agent with defaults. +- **Portable identity (a):** **No.** This is the *anti-persona* — it is entirely project-specific by design (repo purpose, setup commands, dir structure, CI checks, dev guidelines). It travels with the *repo*, not with a role. +- **Owned/managed files (b):** **No.** Purely informational context; it does not declare artifacts it writes nor restrict which files may be edited. (The closest thing: OpenHands *instructs the agent* to **create** an `AGENTS.md` at repo root — but `repo.md` itself isn't a file-ownership contract.) +- **Known/context files (c):** Implicit only — it *is* the curated context. No declared input globs. +- **Processes (d):** Soft — embeds setup/build/test conventions as prose, not a bound workflow engine. +- **Instantiation:** **Always loaded** into context for that repo; transient (prompt injection, not a standing addressable agent). +- **Closeness to our model:** Low — it's the project-pinned (b/c) half with **zero** portable identity. +- **Worth borrowing:** The "always-on, repo-resolved context file the agent both *reads and is told to maintain*" is a clean precedent for your *owns* + *knows* resolved-per-deployment. + +### 1b. Knowledge (keyword-triggered) microagents +- **Definition format:** Markdown + **required** YAML frontmatter. Confirmed fields: `name`, `description`, `triggers` (list of keywords). (V0 also documented a `type: knowledge` / `agent` field across versions.) +- **Portable identity (a):** **Yes — strongest match here.** These are explicitly "reusable across multiple projects," domain expertise (e.g. a `github`/`git` agent) that travels independent of any one repo. This is the "portable identity/knowledge" leg of your model. +- **Owned/managed files (b):** No. +- **Known/context files (c):** **No file-glob/fileMatch.** Verified: activation is **keyword-in-prompt only** — there is **no** filesystem/file-type-based conditional loading in the docs. (Some marketing copy claims "context-aware based on file types"; the primary docs do **not** support that — honest flag.) +- **Processes (d):** Encodes methods/SOPs as triggered prose. +- **Instantiation:** Transient, **lazy** — loaded only when a trigger keyword appears. Not addressable. +- **Closeness to our model:** Medium-high on (a)+(d); misses (b) and (c-as-glob). +- **Worth borrowing:** **Trigger-gated lazy loading** is exactly your "loaded transiently into a conversation/step." Borrow the `triggers:` frontmatter as a cheap activation gate — but note its weakness (keyword-only) and consider adding the file-glob *knows* dimension they lack. + +### 1c. Task microagents (`pr_review.md`, `bug_fix.md`, `feature.md`) +- Workflow templates (the *processes* leg). Documented as present but not formally schema'd as a distinct type. Maps to your (d). + +**V1 delta (Skills):** Same model, renamed. Canonical path `.agents/skills//SKILL.md` (+ optional `README.md`); user-level `~/.agents/skills/`; categories are **Permanent/Repository, Keyword-Triggered, Organization, Global**. "AgentSkills-style progressive disclosure." Public registry (`OpenHands/skills`, npm `@openhands/extensions`) gives a real **portable-persona distribution channel** — directly relevant to your "travels-with-it" leg. + +--- + +## 2. OpenDevin (lineage) + +Not a separate mechanism — **OpenDevin is the former name of OpenHands** (homage to Cognition's Devin; renamed early 2025; now All-Hands-AI). The microagents/skills system is OpenHands-era; surveying OpenDevin separately would be redundant. Honest note: I found **no** distinct "OpenDevin persona" artifact predating the OpenHands microagents design. + +--- + +## 3. OpenClaw (the "identity.md" recollection — **confirmed real**) + +Your operator's memory is accurate. OpenClaw uses a **bootstrap-file bundle** that is the closest whole-system analog to your persona model. + +- **Definition format:** A workspace dir (`~/.openclaw/workspace/`) of **plain Markdown** bootstrap files, injected into the system prompt's "Project Context" on the first turn of a session. Blank files skipped; missing files leave a marker; `openclaw setup` scaffolds defaults. Config in `openclaw.json` (`agents.defaults.workspace`, etc.). Skills are `SKILL.md` folders with YAML frontmatter (`name`, `description`), loaded **on-demand**. +- **Portable identity (a):** **Yes — and explicitly *factored*.** This is the standout: identity is split across files by concern — + - `IDENTITY.md` = **factual identity** (name, vibe, emoji; ~5–15 lines), + - `SOUL.md` = **persona/boundaries/tone** ("what you do / what you never do / how you communicate"), + - `AGENTS.md` = operating instructions/memory rules, + - `USER.md` = user profile, + - `TOOLS.md` = tool guidance, + - `BOOTSTRAP.md` = one-time first-run ritual (self-deletes). + Because it's all on-disk Markdown, copying the workspace ports the persona (portability is implied, not a first-class "travels-with-it-across-projects" abstraction — honest caveat). +- **Owned/managed files (b):** Partial — `MEMORY.md` + `memory/` daily logs are artifacts the agent **maintains**; `AGENTS.md` codifies memory/bill-tracking write rules. No formal "this persona may only edit X" restriction. +- **Known/context files (c):** The bootstrap bundle + `MEMORY.md` are declared, always-injected inputs. `HEARTBEAT.md` is the periodic checklist read on daemon wakeups. No glob/fileMatch inclusion. +- **Processes (d):** `AGENTS.md` (SOPs/safety rails, e.g. "always screenshot after filling a form"), `HEARTBEAT.md` (patrol checklist), `cron/jobs.json`, and `SKILL.md` skills. +- **Instantiation:** **Standing daemon** — one embedded agent per Gateway (`systemd`/`LaunchAgent`, `openclaw gateway`, default `ws://127.0.0.1:18789`), wakes on heartbeat (~30 min). **Addressable** via stable session IDs (JSONL sessions); supports mid-run queue modes (`/queue steer|followup|collect|interrupt`). +- **Closeness to our model:** **Highest of all surveyed.** It hits a (factored identity), partial b (maintained memory), c (declared context), d (SOPs + heartbeat + skills) — the main divergence from yours is **always-standing daemon** vs your **transient-by-default, standing-only-to-patrol**. (And OpenClaw's heartbeat = "patrol continuously" is precisely your standing-agent case.) +- **Worth borrowing:** The **multi-file identity factoring** — `IDENTITY.md` (terse facts) vs `SOUL.md` (persona/tone) vs `AGENTS.md` (operating rules) — is the single best idea to steal: it lets the *portable* core (identity+soul) stay clean while project/operational concerns live in separate, separately-resolved files.

I surveyed `chatdev1.0` as primary. Everything below is from primary source files; where a fetch summary gave a shaky count I say so rather than assert it. + +--- + +## MetaGPT + +**Definition format.** Python class. Each role subclasses `Role` (a Pydantic `BaseModel`); newer ones subclass `RoleZero` (which subclasses `Role`). Identity is **class attributes**; behavior is wired in `__init__` via method calls. E.g. `ProductManager(RoleZero)` sets `name="Alice"`, `profile="Product Manager"`, `goal="Create a Product Requirement Document..."`, `constraints="utilize the same language as the user requirements..."`. + +**Portable identity (your `a`).** Strong and explicit. `Role` defines `name`, `profile`, `goal`, `constraints`, `desc` — all **project-agnostic strings** baked into the class, injected into the LLM system prompt. They carry zero project specifics (no paths, no IDs); the same class drops into any run. This is close to your "portable identity that travels with the persona." + +**Owned/managed files (your `b`).** Yes, but **indirectly** — ownership is expressed as *which Action a role runs*, and the Action writes to a **fixed, project-relative path constant** in `const.py`, resolved under the active `ProjectRepo` (the deployment root). So: +- ProductManager → `WritePRD` → `PRDS_FILE_REPO = "docs/prd"` +- Architect → `WriteDesign` → `SYSTEM_DESIGN_FILE_REPO = "docs/system_design"` (+ `resources/data_api_design`, `resources/seq_flow`) +- ProjectManager → `WriteTasks` → `TASK_FILE_REPO = "docs/task"` +- Engineer → `WriteCode` → source tree via `self.repo.srcs.save()`; summaries to `docs/code_summary` +- QAEngineer → `WriteTest`/`RunCode`/`DebugError` → `tests/`, `test_outputs/` + +The role doesn't *declare* "I own `docs/prd`" in its own body — the binding is `role → action → path-constant`, paths globally defined and re-rooted per deployment via `ProjectRepo`. Functionally equivalent to your "owns project-relative artifacts, resolved per deployment," but the declaration is split across three files, not co-located on the persona. + +**Known/context files (your `c`).** Expressed as **action-level subscriptions, not file inputs.** A role calls `self._watch([...Action types...])`; it then consumes the *messages those actions emitted* (each `Message` carries `cause_by`). Architect `_watch({WritePRD})`; Engineer `_watch({WriteTasks, SummarizeCode, WriteCode, WriteCodeReview, FixBug, WriteCodePlanAndChange})`. So "knows" = "the upstream artifacts named by the actions I watch," dereferenced through the shared repo — typed by *producing action*, not by literal path. + +**Processes (your `d`).** This is MetaGPT's thesis: **SOP encoded as prompts.** Each role's method is a sequence of `Action` objects (`set_actions([...])`), and reaction strategy is declared (`rc.react_mode`: `REACT` think-act loop, `BY_ORDER` sequential, or `PLAN_AND_ACT`). The PM runs `[PrepareDocuments, WritePRD]` `BY_ORDER`. The Action subclass holds the structured prompt + an output schema (`WritePRD` demands Product Goals, User Stories, Competitive Analysis, Requirement Pool). The paper frames the whole system as "SOPs encoded as prompt sequences," with two parts: *role specialization* + *workflow across agents*. + +**Instantiation.** **Standing and addressable** within a run. Roles are long-lived objects hired into a `Team`/`Environment` (`company.hire([ProductManager(), Architect(), ProjectManager(), Engineer()])`), each with a personal message buffer, addressed via `name`/`addresses` routing tags. They idle until a watched message arrives, then react. Handoff = publish a message tagged by `cause_by`; the downstream role's `_watch` picks it up — a **typed pub/sub over a shared file repo**, not direct calls. This differs from your "loaded transiently, becomes standing only to gate/patrol" — MetaGPT roles are standing by default for the whole job. + +**Closeness to your model:** High — clean separation of portable identity (class attrs) from per-deployment artifacts (path-constants × `ProjectRepo`), with explicit owns/knows/process. +**Worth borrowing:** The `role → action → path-constant`-rooted-at-deployment indirection (your "owns, resolved per deployment") and **typed artifact handoff via `cause_by` + `_watch`** instead of free-form chat — directly models your owns/knows as a producer/consumer graph. + +--- + +## ChatDev (classic "chat chain", branch `chatdev1.0`) + +**Definition format.** **JSON config, not code.** Three decoupled files under `CompanyConfig//`: `RoleConfig.json` (who), `PhaseConfig.json` (how, per step), `ChatChainConfig.json` (order). Agents are instantiated by the engine (`chatdev/role_play` via the CAMEL `RolePlaying` substrate) from these configs — you customize a "company" by editing JSON, no subclassing. + +**Portable identity (your `a`).** Present but **thin and prompt-only.** `RoleConfig.json` maps each role name → an **array of prompt strings** (the role's "inception" system prompt). The default ships 9 roles: Chief Executive Officer, Chief Product Officer, Counselor, Chief Technology Officer, Chief Human Resource Officer, Programmer, Code Reviewer, Software Test Engineer, Chief Creative Officer. Example (CEO) literally: `["{chatdev_prompt}", "You are Chief Executive Officer. Now, we are both working at ChatDev...", "Your main responsibilities include being an active decision-maker...", "Here is a new customer's task: {task}.", ...]`. It *is* portable (project enters only via `{task}`/`{modality}` placeholders), but identity = a static prompt blob with **no goal/constraints schema, no knowledge beyond the prose**. Weaker and less structured than your "core role/knowledge" or MetaGPT's typed fields. + +**Owned/managed files (your `b`).** **Not declared per role.** Roles don't own artifacts. Artifacts (code, manual, requirements, env doc) accumulate in a shared mutable blackboard — `ChatEnv` (`chatdev/chat_env.py`) — and are flushed to a single project directory. No `architect → architecture.md` style ownership binding exists; *phases* mutate shared state, roles don't hold files. This is the **biggest divergence** from your model: ChatDev has no per-persona owned-artifact concept. + +**Known/context files (your `c`).** **Not declared.** A phase reads from and writes to the shared `ChatEnv` (whole prior code/requirements/designs in scope as prompt context); there's no per-role declared input set. "Knowledge" is whatever the phase prompt template injects via placeholders (`{task}`, `{description}`, `{modality}`, `{language}`, `{ideas}`, `{gui}`, `{codes}`, `{unimplemented_file}`). + +**Processes (your `d`).** **The strongest, most explicit part — but it lives on the *phase/chain*, not the persona.** Process is a two-level pipeline: +- `ChatChainConfig.json` → ordered `chain`: `DemandAnalysis → LanguageChoose → Coding → CodeCompleteAll → CodeReview → Test → EnvironmentDoc → Manual`. Each entry has `phaseType` (`SimplePhase` = one dialogue, or `ComposedPhase` = looped, e.g. `CodeReview` cycleNum 3, `Test` cycleNum 3, `CodeCompleteAll` cycleNum 10), `max_turn_step`, `need_reflect`. +- `PhaseConfig.json` → each phase binds **exactly two roles** (`assistant_role_name`, `user_role_name`) + a `phase_prompt` template. E.g. `Coding`: assistant `Programmer`, user `Chief Technology Officer`. The SOP is the *sequence of two-agent role-plays*, not a method attached to any one agent. + +**Instantiation.** **Transient and pairwise.** No standing addressable roster — for each phase the engine spins up a CTO↔Programmer (etc.) `RolePlaying` dialogue, runs ≤`max_turn_step` turns (optionally a `Counselor`↔`CEO` *reflection* sub-chat), writes results to `ChatEnv`, and tears the pairing down. Roles are summoned per phase. Handoff is **implicit via shared `ChatEnv` state** advanced by the chain — not messages, not typed subscriptions. This is *closer* to your "loaded transiently" intuition than MetaGPT, but there's no "becomes standing to gate/patrol" path at all. + +**Closeness to your model:** Moderate-low — excellent declarative *process* (chain/phase) and portable-ish prompt identity, but **no owns/knows per persona** (artifacts live on a shared blackboard) and roles are transient phase-pairings. +**Worth borrowing:** The **3-file split (identity / step-method / ordering)** and especially the **`ComposedPhase` loop primitive** (`cycleNum`, reflection) — a clean, data-driven way to express your "processes" and the "gate work / patrol continuously" iterative-review modes without code. + +--- + +## Cross-cutting read for your design + +- **Identity (`a`):** Both keep identity project-agnostic and prompt-injected. MetaGPT's *typed* fields (`profile`/`goal`/`constraints`) are the better template for "portable identity + core knowledge" than ChatDev's prose blob. +- **Owns (`b`):** Only MetaGPT has anything like it, and it's **emergent** (`role → action → path-constant`, re-rooted by `ProjectRepo`) rather than a first-class `owns:` declaration on the persona. **Neither system has your clean "persona declares the project-relative artifacts it maintains."** That's a genuine gap your model fills — worth making first-class. +- **Knows (`c`):** Neither declares file inputs literally. MetaGPT types inputs by *producing action* (`_watch` + `cause_by`); ChatDev gives whole shared state. MetaGPT's typed-producer approach is the more borrowable basis for declared inputs. +- **Processes (`d`):** MetaGPT binds method **to the persona** (`set_actions` + `react_mode`); ChatDev binds it **to the pipeline** (chain + phase JSON). Your "processes it applies" leans MetaGPT-shaped (per-persona), but ChatDev's externalized chain is the better model if you want the *workflow* to be reconfigurable independent of personas. +- **Instantiation (`b`/standing-vs-transient):** Your "transient by default, standing only to gate/patrol" matches **neither** cleanly — MetaGPT roles are standing-for-the-run; ChatDev roles are transient phase-pairings with no standing mode. Your hybrid (transient load + promotable to addressable gatekeeper/patrol) is novel relative to both. + +**Honesty notes:** PhaseConfig key count came back ambiguous (12 vs 13 in fetch summaries) — I report only the chain-level phase order, which I verified directly, and don't assert an exact PhaseConfig key count. Concrete-role file contents (PM/Architect/Engineer) are verified from source; the QA role's exact attrs I inferred from the established `_watch`/`set_actions` pattern + action filenames rather than a full file read, so treat QA specifics as pattern-level, not line-verified. diff --git a/specs/tk-oe8o0/research/survey-3-crewai-autogen-langgraph.md b/specs/tk-oe8o0/research/survey-3-crewai-autogen-langgraph.md new file mode 100644 index 0000000..0426cb1 --- /dev/null +++ b/specs/tk-oe8o0/research/survey-3-crewai-autogen-langgraph.md @@ -0,0 +1,64 @@ +--- +name: Prior-art survey 3 — CrewAI, AutoGen & LangGraph +description: Full primary-source survey — CrewAI's Agent/Task identity-vs-output split, AutoGen's system_message vs description two-field identity, and LangGraph's reducers as artifact-ownership contracts.

The Agent is defined independently of any task and composed into a crew by reference — the closest analog to your "portable identity" of the three. +- **Owned/managed files:** **No — and this is the key finding.** Output ownership lives on the **`Task`**, not the Agent: `output_file`, `output_json`, `output_pydantic`, `create_directory`, `markdown`, `guardrail`. The Task binds a worker via its `agent` field. So "who I am" and "what I emit" are split across two objects. +- **Known/context files:** Partially at the Agent level via `knowledge_sources` (declared readable knowledge) + `embedder`/RAG tools. Task-to-task inputs are declared on the Task via `context` (list of upstream Tasks), not on the Agent. +- **Processes:** Indirect. The Agent does not enumerate its methods; `Task`s reference the Agent, and the crew's `process` (sequential/hierarchical) drives execution. +- **Instantiation:** Mostly transient/composed, but addressable: `Agent.kickoff()` lets an agent run directly without a task/crew, and `memory` gives it persistence within a crew. Not a long-lived network-addressable service. +- **Closeness to our model:** Closest overall — explicit reusable role identity, declared knowledge inputs, transient-by-default with a direct-invoke escape hatch. +- **Worth borrowing:** The **identity/output split** (persona = portable role; *owns* artifacts declared elsewhere and resolved per deployment) — CrewAI independently arrived at exactly your (a)-vs-(b) separation by putting `output_file` on Task, not Agent. + +--- + +## Microsoft AutoGen — `ConversableAgent` / `AssistantAgent` + +- **Definition format:** Python class instantiation. `ConversableAgent(name=..., system_message=..., description=..., llm_config=...)`; `AssistantAgent`/`UserProxyAgent` are subclasses with preset defaults. (v0.4 AgentChat: same shape, `model_client` replaces `llm_config`.) +- **Portable identity:** **Yes, but prose-only.** Identity is the free-text `system_message` ("You are a helpful AI Assistant." by default). It is reusable and task-independent, but unstructured — no role/goal/backstory decomposition. Notably AutoGen splits identity into **two fields**: `system_message` (steers the model) and `description` (a short capability blurb other agents/the `GroupChatManager` read to decide *when to call this agent*). That description field is a clean analog to a persona's externally-advertised, addressable interface. +- **Owned/managed files:** **No.** No owned-output declaration. Code-execution agents reference a `work_dir`, but that's executor config, not an agent-level artifact contract. +- **Known/context files:** **No declared file inputs.** Context enters as conversation history (`chat_messages`/carryover), not as declared context files. +- **Processes:** Strong, but conversational rather than artifact-based. Behavior binds via `register_reply` (trigger→reply-fn), `initiate_chat`, and team/`GroupChat` membership. v0.4 adds `handoffs` and `run()`/`run_stream()`. +- **Instantiation:** **Standing and addressable** — the most "agent-like." Instances are stateful (`chat_messages`, `send`/`receive`, `on_messages`, `save_state`/`load_state`, `on_reset`), uniquely named, and referenced by name in multi-agent chats. +- **Closeness to our model:** Captures (a) identity and the standing/addressable end-state well; weak on (b)/(c) — no declared owned/known *files*, only message state. +- **Worth borrowing:** The **two-field identity** — separate the model-facing self-description from the **externally-advertised `description` used for routing/selection.** Maps directly onto "loaded transiently … becomes addressable to gate work": the `description` is what a coordinator reads to decide whether to stand the persona up. + +--- + +## LangGraph — nodes + typed `State` + +- **Definition format:** Graph-centric. `StateGraph(StateSchema)` with nodes added via `add_node(name, fn)`; nodes are plain functions `(state, config) -> partial-state-update`. State is a `TypedDict`/dataclass/Pydantic schema. +- **Portable identity:** **No, at the core layer.** Docs are explicit: "Nodes: Functions that encode the logic of your agents" — there is no agent/role identity object; `StateGraph` is parameterized by *state schema only*. Identity exists only as a named function inside one graph. **The prebuilt layer adds it:** `create_react_agent(model, tools, prompt=..., name=...)` (now deprecated → `langchain.agents.create_agent` with middleware) produces a reusable, named, portable agent that can itself be embedded as a node/subgraph in a larger graph. So portability is opt-in via the prebuilt factory, absent in raw LangGraph. +- **Owned/managed files:** **No file ownership; field-level *state* ownership instead.** This is LangGraph's distinctive contribution: each State key declares a **reducer** via `Annotated[type, reducer]` (e.g. `add_messages`) governing how concurrent writes merge (default = overwrite/last-write-wins). Ownership is by merge-rule, not by file path. +- **Known/context files:** No declared file inputs. Nodes implicitly read the shared `State`; docs note nodes "do not declare which keys they read or write" — read/write sets are implicit. **Subgraphs** can keep **private channels** outside the parent I/O schema (a "knows internally vs exposes" boundary), with a streaming-leak caveat. +- **Processes:** The graph *is* the process — edges/`Command(goto=...)`/conditional routing are first-class; the workflow is the primary artifact, agents secondary. +- **Instantiation:** Nodes are named and addressable as graph members (`add_edge("a","b")`) but execution is transient per super-step; no standing service. Persistence is the *graph's* checkpointer, not a per-agent identity. +- **Closeness to our model:** Furthest from a persona model at its core (workflow-first, identity-thin), yet it uniquely formalizes **artifact ownership semantics** that your *owns* clause leaves implicit. +- **Worth borrowing:** **Reducers as ownership contracts** — when two personas touch the same owned artifact, a declared merge function (append / last-write / custom) resolves contention deterministically. Also the **subgraph private-channel** pattern for *knows*-internal vs externally-visible context. + +--- + +## Cross-cutting takeaways for your model + +1. **Identity-vs-output split is validated prior art, not a quirk:** CrewAI puts identity on `Agent` and outputs on `Task` — independent confirmation of your (a) portable-identity / (b) owns separation. Borrow it: keep the persona's *owns* as references resolved per deployment, not baked into identity. +2. **Two-tier identity for the transient→addressable transition:** AutoGen's `system_message` (self) + `description` (advertised, routing-facing) is the cleanest match to "transiently loaded, becomes addressable to gate work." A coordinator reads the `description`-equivalent to decide when to stand the persona up. +3. **No surveyed system declares *known/context input files* on the role** the way your *knows* clause does — closest is CrewAI's `knowledge_sources` (agent-level) and Task `context` (task-level). This is a genuine gap your model fills; it's a differentiator, not a missing-homework item. +4. **Ownership semantics are under-specified everywhere except LangGraph.** If personas can co-write artifacts, adopt LangGraph-style per-artifact reducers to make *owns* contention deterministic. diff --git a/specs/tk-oe8o0/research/survey-4-roo-cline-cursor-aider.md b/specs/tk-oe8o0/research/survey-4-roo-cline-cursor-aider.md new file mode 100644 index 0000000..a256e02 --- /dev/null +++ b/specs/tk-oe8o0/research/survey-4-roo-cline-cursor-aider.md @@ -0,0 +1,92 @@ +--- +name: Prior-art survey 4 — Roo Code, Cline, Cursor & Aider +description: Full primary-source survey — Roo Code custom modes' fileRegex edit-fence, Cline rules, Cursor's four-mode rule activation taxonomy (always / glob-auto / description-requested / manual), and Aider's read-only vs editable file split.

Global rules in `~/Documents/Cline/Rules`; workspace rules take precedence on conflict. Also ingests Cursor/Windsurf rules and `AGENTS.md`. +- **Portable identity.** Partial. Global-vs-workspace split gives portability of *instructions*, but there is **no named role/persona object** — rules are ambient guidance, not an identity you instantiate or switch to. (Cline's separate Plan/Act distinction is a workflow phase, not a persona.) +- **Owned/managed files.** None. Docs show **no file-edit-restriction mechanism** within rules; rules cannot fence editable files. No write-manifest either. +- **Known/context files.** Conditional activation via YAML frontmatter `paths:` globs (e.g. `src/components/**`, `*.test.ts`) — a rule loads only when context files match. This is *input-gated activation* (closest to your *knows*), but it scopes *when the rule applies*, not *what the persona reads*. +- **Processes.** Method-as-prose in the rule body; toggleable on/off via the Rules panel (the "self-improving"/AI-editable angle). No structured workflow binding. +- **Instantiation.** Fully transient/ambient — text appended to the prompt; nothing standing or addressable. +- **Closeness:** Low–moderate — portable-vs-project and glob-gated activation only; no identity, no ownership. +- **Worth borrowing:** The runtime **toggle UI** for rules and AGENTS.md interop; the `paths:` glob is a lightweight precedent for declaring context relevance. + +## 3. Cursor — rules (`.cursor/rules/*.mdc`) + +- **Definition format.** `.mdc` = YAML frontmatter (`description`, `globs`, `alwaysApply`) + Markdown body, one file per rule under `.cursor/rules/` (nestable). Plain `.md` w/o frontmatter is ignored for conditional loading. Legacy: single-file `.cursorrules` (deprecated, still read). +- **Portable identity.** Partial. **User Rules** = global (across projects, Chat-only); **Project Rules** = per-repo. Like Cline, this is portable *instruction*, not a named/switchable persona object. +- **Owned/managed files — context only.** Primary doc states plainly: **"Rules provide context only — they do not restrict file editing."** No ownership/fence. The `globs` field looks ownership-like but only controls *auto-attachment of the rule*, not write permission. +- **Known/context files.** Strongest declarative *knows* of the four, via four activation types keyed on frontmatter: + - **Always** (`alwaysApply: true`) — every request; + - **Auto Attached** (`globs` set) — loads when a matching file is in context; + - **Agent Requested** (`description` set, `alwaysApply: false`) — model decides from the description; + - **Manual** (neither) — only via `@rule-name`. +- **Processes.** Method-as-prose in the body; no workflow binding. +- **Instantiation.** Transient/ambient; `@rule-name` makes a rule *referenceable* but not an agent. No standing/addressable persona. +- **Closeness:** Moderate on *knows* (rich glob/description/always taxonomy) and portable-vs-project; **zero on *owns*** by explicit design. +- **Worth borrowing:** The four-mode activation taxonomy (always / glob-auto / description-requested / manual) is the cleanest vocabulary for your *knows* loading semantics — adopt the naming directly. + +## 4. Aider — `CONVENTIONS.md` + read-only/editable split + +- **Definition format.** Convention = ordinary Markdown (`CONVENTIONS.md`, name conventional, not magic). Loaded via `/read-only CONVENTIONS.md`, `aider --read CONVENTIONS.md`, or `.aider.conf.yml` `read: [CONVENTIONS.md, ...]`. Verbatim recommendation: *"It's best to load the conventions file with `/read CONVENTIONS.md` or `aider --read CONVENTIONS.md`"* (so it's read-only + prompt-cached). +- **Portable identity.** Weak. A conventions file is portable project context, but there is **no role/persona/mode** at all — Aider has no named agent identity construct. +- **Owned/managed files — an inverted, per-session ownership.** Aider's core distinction is the one place your *owns* and *knows* both appear, as a runtime split of the chat file set: + - **Editable** files (`/add`) — the model may write them; + - **Read-only** files (`/read-only`, `--read`) — referenced, never edited. + This is effectively a *positive editable-set* (the inverse of Roo's negative regex fence): ownership is "which files I'm allowed to edit this session," chosen per session rather than declared on a persona. No glob/regex; it's an explicit file list. (Note an open request, `Aider-AI/aider#3425`, to separate read-only vs editable via `.aiderignore` — i.e. this is list-based, not pattern-based, today.) +- **Known/context files.** The read-only set *is* the declared read context; `.aider.conf.yml read:` makes it project-persistent. Matches your *knows* well, by explicit path. +- **Processes.** Conventions body carries method-as-prose; Aider's own architect/code modes are workflow phases, not personas. +- **Instantiation.** Per-session, transient; nothing standing/addressable. +- **Closeness:** Moderate on *owns*/*knows* (clean editable-vs-readable split, persistable), but no identity and no patterns. +- **Worth borrowing:** The **editable-set ⊕ read-only-set** framing — pairs naturally with Roo's regex fence: your "owns" could express *both* a positive write-manifest (Aider-style) and a negative edit-fence (Roo-style), and Aider shows read-only context should be **prompt-cached**. + +--- + +## Synthesis for your model + +- **Owns (edit-restriction):** Only **Roo Code** enforces it — regex fence on the `edit` capability with a typed `FileRestrictionError`. **Aider** offers the positive complement (per-session editable set). **Cursor explicitly does not restrict edits; Cline has no such mechanism.** Borrow Roo's regex-fence shape + Aider's positive editable-set; your "owns" can carry both a write-manifest and an edit-fence, which no single system does. +- **Knows (read context):** **Cursor's** four-type activation (always / glob-auto / description-requested / manual) is the richest declarative vocabulary; **Cline's** `paths:` and **Aider's** read-only set are simpler precedents. Borrow Cursor's taxonomy naming. +- **Portable identity + per-deployment override:** **Roo** is the only true match (global mode ⇄ project `.roomodes` override by `slug`); Cline/Cursor only split global-vs-project *instructions* with no identity object. +- **Instantiation (standing/addressable):** None run a persona as a standing daemon; **Roo's** switchable named modes (and Cursor's `@rule-name` reference) are the nearest "becomes addressable" precedents — your transient-load-then-promote-to-standing-agent design appears to be **net-new** relative to all four. +- **Processes:** Uniformly weak — all four encode method as prose in a role/rules body; none bind a persona to a structured workflow.

Claude Code subagents + +- **Definition format:** One Markdown file per agent with YAML frontmatter; the Markdown body **is** the system prompt. Loaded at session start. Also definable transiently via `--agents ''` (same field set, `prompt` key replaces the body). +- **Portable identity:** Yes, strongly. The frontmatter `name` + `description` + body prompt are a self-contained role. Scope ladder: managed (org) > `--agents` (session) > `.claude/agents/` (project) > `~/.claude/agents/` (all your projects) > plugin `agents/` (lowest). User-scope and plugin distribution are the explicit portability paths ("Reuse configurations across projects"). Identity comes **only** from the `name` field, not the path. +- **Owned/managed files:** Not as a declared artifact list. The closest analog is `memory: user|project|local`, which grants a persistent dir (`~/.claude/agent-memory//`, etc.) the agent reads/curates across sessions (auto-injects first 200 lines of its `MEMORY.md`). That's owned *state*, not declared *outputs*. +- **Known/context files:** No glob/fileMatch inclusion. A non-fork subagent starts with a **fresh, isolated** context (system prompt + delegation message + CLAUDE.md hierarchy + git snapshot); it does not declare input file patterns. `skills:` can preload whole skills into context. Context-scoping is by isolation, not by declared globs. +- **Processes:** Bound via the prompt body plus `hooks` (`PreToolUse`/`PostToolUse`/`Stop`→`SubagentStop`) for lifecycle validation, and `skills:` for preloaded methods. No first-class "workflow" object. +- **Instantiation:** Transient by default — spawned per task via the Agent tool, runs in its own context window, returns only a summary. Tool grants: `tools` (allowlist) / `disallowedTools` (denylist), `Agent(type,…)` to gate which sub-subagents it may spawn, plus `permissionMode`, `model`, `maxTurns`, `mcpServers`, `effort`, `isolation: worktree`, `background`. **Addressable:** yes — `@agent-` / `@"name (agent)"`, natural-language naming, or session-wide via `--agent ` (the agent's prompt replaces the default system prompt). Resumable by agent ID. It becomes "standing" only as a background task or via `--agent`. +- **Closeness:** Very close to the *standing/addressable-agent* end of your model (gate-work + patrol), with portable identity — but weak on declared owns/knows. +- **Worth borrowing:** The scope-precedence ladder (managed > session > project > user > plugin) and `Agent(type,…)` spawn-gating are a clean, ready-made model for "portable identity + who-can-invoke-whom." + +## 2. Claude Code Skills + +- **Definition format:** A directory with `SKILL.md` (YAML frontmatter + Markdown body) as the entrypoint, optionally bundling `scripts/`, `references/`, `assets/`, templates. Follows the **Agent Skills open standard** (cross-tool). Only `name`/`description` are meaningful-required (Claude Code makes both optional, defaulting `name` to the dir). +- **Portable identity:** Yes — this is the system's whole point ("create once, use automatically," "package domain expertise"). Same scope ladder as subagents (enterprise > personal `~/.claude/skills/` > project `.claude/skills/` > plugin). API/claude.ai variants package as zip/`skill_id`. Caveat: skills **do not sync across surfaces** (Code/API/claude.ai managed separately). +- **Owned/managed files:** Bundles owned artifacts (scripts/templates/references) that travel **with** the persona — the strongest "owns its artifacts" story here — but these are inputs/tools it carries, not project-relative outputs it maintains. No declared write-targets. +- **Known/context files:** No glob/fileMatch *auto-inclusion*. Instead: **progressive disclosure** — L1 metadata (name+description, always in prompt, ~100 tok) → L2 `SKILL.md` body on trigger → L3 bundled files read on demand via bash. Plus **dynamic context injection**: `` !`` `` lines run and inline output before Claude sees the body (e.g. `!​`git diff HEAD``). Context is pulled by reference/command, not matched by file glob. +- **Processes:** This is the core — a skill *is* a packaged method/workflow (`context: fork` runs it in a subagent; `disable-model-invocation: true` makes it a deliberate `/command`). +- **Instantiation:** Transient and **non-addressable as an agent** — runs inline in the main conversation context (or a forked subagent). Tool grant: `allowed-tools: Read Grep` (space-separated; note the hyphenated spelling, distinct from subagents' comma `tools:`). Invoked by Claude automatically or by the user as `/skill-name`. Never "stands up" as an agent. +- **Closeness:** Closest to your *processes* + *portable identity* facets, and to the "loaded transiently" default — but deliberately the opposite of "standing/addressable." +- **Worth borrowing:** Progressive disclosure (3-level lazy load keyed off a cheap always-on description) + `!`cmd`` dynamic injection — directly model your *knows* facet as **pulled-on-demand** rather than glob-included, which scales context far better. + +## 3. Kiro steering files + +- **Definition format:** `.kiro/steering/*.md`, YAML frontmatter (triple-dash) carrying an `inclusion` mode. Three default foundational files: `product.md`, `tech.md`, `structure.md`. +- **Portable identity:** Weak. Files are workspace-specific (`.kiro/steering/`) or machine-global (`~/.kiro/steering/`); docs explicitly say they're "not inherently portable across projects." (And a known bug — issue #6171 — that global `~/.kiro/steering/` files don't inject regardless of mode.) These are *standards/context*, not an addressable role. +- **Owned/managed files:** None declared. Steering is read-only guidance Claude *consumes*; it doesn't declare artifacts it writes. +- **Known/context files:** **This is the standout match for your *knows* facet.** `inclusion` modes: + - `always` (default) — loaded into every interaction; + - `fileMatch` + `fileMatchPattern: ""` (single or array, e.g. `["**/*.ts","**/*.tsx"]`, `"app/api/**/*"`) — auto-included **only** when the active file matches the glob; + - `manual` — pulled on demand via `#steering-file-name` in chat. + + This is exactly declared, glob-scoped context inclusion. (Reported flaky for extension-only patterns — issue #1643.) +- **Processes:** Not in steering itself. The **spec workflow** (separate, `.kiro/specs/{feature}/`) is the process layer: `requirements.md` → `design.md` → `tasks.md`, a 3-phase requirements→design→tasks→implementation flow, with tasks grouped into dependency "waves." Steering supplies durable standards *to* that workflow. +- **Instantiation:** Not an agent at all — purely context/guidance documents; transient per-interaction, never standing or addressable. No tool grants. +- **Closeness:** The purest expression of your *knows* (project-relative, glob-scoped, conditional) — and `manual`/`#ref` mirrors your "transient until summoned." But it has no identity/owns/agent facets. +- **Worth borrowing:** Adopt `inclusion: {always | fileMatch + fileMatchPattern | manual}` near-verbatim for your *knows* declaration — it's the cleanest existing schema for "read this context only when working on matching files," and the `always`/`fileMatch`/`manual` triad maps onto portable-core vs. project-scoped vs. on-demand context. + +## 4. Amazon Q Developer (CLI custom agents) + +- **Definition format:** One **JSON** file per agent in `.amazonq/cli-agents/` (local) or a global location; precedence local > global > built-in default. Generated via `/agent generate`; run via `q chat --agent `. +- **Portable identity:** Yes — `name` + `description` + `prompt` define a reusable role, with local-vs-global scoping for cross-project reuse. Same two-tier (project/global) portability shape as the Claude systems. +- **Owned/managed files:** Not a declared output set. (`fs_write` capability + `toolsSettings.allowedPaths` bound *where* it may write, but it doesn't enumerate maintained artifacts.) +- **Known/context files:** **Yes, and closest to "declared inputs by glob."** `resources` is an array of `file://` URIs **with glob support**, e.g. (verbatim from issue #2510): + ```json + "resources": ["file://AmazonQ.md", "file://README.md", "file://.amazonq/rules/**/*.md"] + ``` + These are statically loaded into context. Beyond static `resources`, **context `hooks`** inject *dynamic* context (e.g. run `git status` and feed the output in) — combining Kiro's glob-inclusion idea with Skills' command-injection idea in one schema. +- **Processes:** Via `prompt` + `hooks` (dynamic context / lifecycle). No separate workflow object. +- **Instantiation:** Transient per `q chat --agent` session. Tool grants are the richest here: `tools` (e.g. `["*"]`), `allowedTools` (auto-trust allowlist — names like `fs_read`, `execute_bash`, MCP tool names), `toolAliases`, `mcpServers` (inline command/args/env), and **`toolsSettings`** with fine-grained `allowedPaths`/`deniedPaths` (fs tools) and `allowedCommands`/`deniedCommands` (bash). Invoked by name on the CLI; not a continuously-addressable standing agent. +- **Closeness:** The most complete single-artifact match to your model — identity (`prompt`) + knows (`resources` globs + `hooks`) + tool grants in one declaration — just JSON instead of frontmatter+body, and transient-only. +- **Worth borrowing:** Two ideas: (1) `resources: ["file://…/**/*.md"]` as an explicit *static-include* glob list, paired with (2) `toolsSettings` path/command allow-&-deny lists for capability scoping finer than a tool allowlist — together they let one persona declare *knows* and bounded *owns*-write-scope side by side. + +--- + +## Synthesis against your four facets + +| Facet | Best prior art | How it's expressed | +|---|---|---| +| **(a) portable identity** | CC subagents / Skills / Q agents | Reusable `name`+`description`+prompt(body or `prompt`); user/global scope + plugin packaging for cross-project travel. Scope-precedence ladder (managed > session > project > user > plugin) is the reusable pattern. | +| **(b) owns (writes/maintains)** | *Weakest across the board* | No system declares output artifacts. Nearest: CC subagent `memory:` (owned state dir), Skills' bundled `scripts/templates` (owned carried assets), Q `toolsSettings.allowedPaths` (bounded write scope). **Gap to fill yourself.** | +| **(c) knows (declared inputs)** | **Kiro steering** + **Q `resources`** | Kiro `inclusion: fileMatch`/`fileMatchPattern` glob = conditional context; Q `resources: file://…/**/*.md` = static glob include; Skills' progressive disclosure + `!`cmd`` = pulled-on-demand. Three viable models: glob-conditional, static-glob, lazy-pull. | +| **(d) processes** | **Skills** (+ Kiro specs) | A Skill *is* a packaged method; Kiro specs give a requirements→design→tasks workflow with dependency waves; hooks bind lifecycle steps. | +| **transient → standing/addressable** | **CC subagents** | Default transient (spawn-summarize-return); becomes standing via `--agent`/background; addressable via `@agent-` and resumable by ID. The only surveyed system that cleanly spans both. | + +**Bottom line for your design:** No single prior-art system covers all four facets. Subagents own the *identity + transient↔standing/addressable* axis; Skills own *processes + portable-packaging + lazy context*; Kiro steering owns *declared, glob-scoped knows*; Amazon Q is the densest single schema (identity + glob-resources + dynamic hooks + fine-grained tool/path scoping). The unowned territory is **(b) declared owned/maintained artifacts** — every system gives you write *capability* or *scope*, none lets a persona declare the project-relative artifacts it *maintains*. That's the novel slot your model adds, and worth designing deliberately rather than borrowing. diff --git a/specs/tk-ohrlc/README.md b/specs/tk-ohrlc/README.md new file mode 100644 index 0000000..479145b --- /dev/null +++ b/specs/tk-ohrlc/README.md @@ -0,0 +1,72 @@ +--- +name: Personas mechanics — investigation record (tk-ohrlc) +description: Work record for tk-ohrlc — the investigation that settles the four deferred "Mechanics" questions behind docs/personas.md (skill load paths, subagent skill loading, persona-process scoping, the assume-persona entry point), verified against current Claude Code docs.

It can invoke skills via the Skill tool, and — + key — its **`skills:` frontmatter preloads full skill bodies at startup**. That is the + primitive that makes "process-skills ride with the persona." +3. **Persona-process scoping.** No native per-agent *visibility* scoping of project + skills (every description sits in every session's context). Curate via: subagent + `skills:` preload, a disabled-by-default **plugin**, `disable-model-invocation` + (removes the description from context but blocks preload — a real exclusivity + constraint), or `skillOverrides` settings. `allowed-tools` scopes **capability, not + visibility** — don't conflate. +4. **Assume-persona entry point.** In-session: invoke the persona identity skill via its + `/` command (it persists for the session).

Where the two disagreed, the +> primary-source page wins and the correction is called out inline. + +--- + +## Q1 — Where skill files actually load from (flat vs. nested discovery) + +**A skill is a directory, not a flat file.** Each skill is `/SKILL.md` +(a directory whose required entrypoint is `SKILL.md`); the directory may also hold +supporting files (scripts, references, templates) that load only when referenced. + +**Locations and precedence** ([skills §Where skills live](https://code.claude.com/docs/en/skills)): + +| Scope | Path | Visible in | +|---|---|---| +| Managed/enterprise | managed-settings location | all users on the machine | +| Personal | `~/.claude/skills//SKILL.md` | all your projects | +| Project | `.claude/skills//SKILL.md` | this project only | +| Plugin | `/skills//SKILL.md` | where the plugin is enabled | + +> Collision rule, quoted: *"When skills share the same name across levels, +> enterprise overrides personal, and personal overrides project. Plugin skills use a +> `plugin-name:skill-name` namespace, so they cannot conflict with other levels."* +> Note the counter-intuitive bit: **personal overrides project**. A skill also +> beats a same-named `.claude/commands/` command. + +**Flat WITHIN a `.claude/skills/`, but discovery spans MANY `.claude/skills/` +directories.** This is the precise answer to the flat-vs-nested question, and it is +the crux for the persona design: + +- Inside a single `skills/` directory, discovery is **one level deep**: + `skills//SKILL.md`. You **cannot** group as + `skills///SKILL.md` and have the inner skill discovered. +- But Claude Code discovers skills across **multiple** `.claude/skills/` directories + ([skills §Automatic discovery from parent and nested directories](https://code.claude.com/docs/en/skills)), + quoted: *"Project skills load from `.claude/skills/` in your starting directory and + in every parent directory up to the repository root… When you work with files in + subdirectories below your starting directory, Claude Code also discovers skills + from nested `.claude/skills/` directories on demand. For example, if you're editing + a file in `packages/frontend/`, Claude Code also looks for skills in + `packages/frontend/.claude/skills/`. This supports monorepo setups…"* +- `.claude/skills/` inside an `--add-dir`/`/add-dir` directory is also loaded + (an explicit exception — `permissions.additionalDirectories` does **not** load skills). +- A skill folder can become a one-folder plugin by adding `.claude-plugin/plugin.json` + — it then loads as `@skills-dir` and can bundle agents/hooks/MCP. + +**SKILL.md frontmatter** (current field set, [skills §frontmatter reference](https://code.claude.com/docs/en/skills)): +`name` (display only; the **directory name** is what you type to invoke), +`description` (drives auto-selection; combined `description`+`when_to_use` capped at +1,536 chars), `argument-hint`, `arguments`, `disable-model-invocation`, +`user-invocable`, `allowed-tools`, `disallowed-tools`, `model`, `effort`, +`context` (`fork`), `agent` (subagent type when `context: fork`), `paths` (globs +that gate auto-activation). Bundled scripts resolve via `${CLAUDE_SKILL_DIR}`. + +**Cost model:** in a regular session, **descriptions are always in context** so +Claude knows what exists; **the body loads only on invocation** and then persists for +the rest of the session (re-attached on compaction within a shared budget). This +matters for Q3. + +**Persona implication.** "A persona owns several process-skills grouped together" +cannot be expressed as nested skill dirs under one `.claude/skills/`. The three real +ways to express the grouping: +1. **Flat naming convention** — `architect`, `architect-review`, `architect-adr` + under one `.claude/skills/`. Simple; no isolation (see Q3). +2. **A plugin per persona** — `persona-architect/skills/{identity,review,adr}/SKILL.md`, + invoked `/persona-architect:review`. Gives grouping **and** namespacing **and** + on/off gating (see Q3). Cleanest for "ride with the persona." +3. **Package-scoped `.claude/skills/`** — only helps if personas map to monorepo + subtrees; not a natural fit for role-based personas. Noted for completeness. + +--- + +## Q2 — How a subagent consumes / loads a skill + +**Subagents are `.claude/agents/.md`** (also `~/.claude/agents/`, managed, and +plugin scopes). Unlike skills, **agent files are discovered recursively** — subfolders +like `agents/review/` are fine; identity comes only from the `name` frontmatter field, +and duplicate names within a scope are silently de-duplicated +([sub-agents](https://code.claude.com/docs/en/sub-agents)). + +**A subagent runs in its own fresh context window.** Its system prompt is the agent +file's markdown body only (plus minimal env like cwd) — *"Subagents receive only this +system prompt … not the full Claude Code system prompt."* It does **not** inherit the +parent's conversation history or the skills the parent already invoked. So skills do +**not** leak parent→child. + +**Two distinct ways a subagent gets a skill — this is the key finding:** + +1. **Preload at startup via the `skills:` frontmatter field** + ([sub-agents §Preload skills into subagents](https://code.claude.com/docs/en/sub-agents#preload-skills-into-subagents)), + quoted: *"Skills to preload into the subagent's context at startup. The full skill + content is injected, not just the description. Subagents can still invoke unlisted + project, user, and plugin skills through the Skill tool."* + ```yaml + --- + name: api-implementer + description: Implement API endpoints + skills: + - api-conventions + - error-handling-patterns + --- + Implement API endpoints. Follow the conventions from the preloaded skills. + ``` + The full SKILL.md **body** (not just the description) lands in the subagent's + context at spawn. **This is the primitive that makes "process-skills ride with the + persona" real.** + +2. **Invoke on demand via the Skill tool.** A subagent can discover and invoke any + project/user/plugin skill at runtime — *unless* `Skill` is omitted from its `tools` + allowlist or listed in `disallowedTools`. Per the docs, to preload you use the + `skills` field **rather than** listing `Skill` in `tools`; to forbid skill use + entirely, omit/deny `Skill`. + +**Important interaction (verified, and an easy trap):** *"You cannot preload skills +that set `disable-model-invocation: true`, since preloading draws from the same set of +skills Claude can invoke."* So the field that hides a skill from plain-worker context +(Q3) **also** makes it ineligible for `skills:` preload. The two levers are mutually +exclusive on the same skill — see Q3 for the consequence. + +**Inverse mechanism for completeness:** a *skill* with `context: fork` (+ `agent:`) +runs **its own content as the task** inside a forked subagent +([skills §Run skills in a subagent](https://code.claude.com/docs/en/skills)). That is +the opposite direction from `skills:` preload: `context: fork` pushes a skill *into* a +chosen agent; `skills:` pulls skills *into* an agent you defined. The docs note both +use the same underlying system. + +**Persona implication.** A persona realized as a **subagent** can carry exactly its +process-skills via `skills:` — they enter the persona's isolated context and never +touch a plain worker's context. A persona realized as a **plain in-session skill load** +(Q4) does not get this isolation; its process-skills are governed by normal in-context +discovery (Q3). + +--- + +## Q3 — Scoping process-skills to a persona (without bloating plain workers) + +**The bloat is real and the docs confirm the mechanism.** Every project/personal skill +in scope has its **description injected into every session's context** so Claude can +choose it; only the body is lazy. Descriptions share a **skill-listing budget** +(tunable via `skillListingBudgetFraction` / `SLASH_COMMAND_TOOL_CHAR_BUDGET`; each +entry capped 1,536 chars, tunable via `maxSkillDescriptionChars`). There is **no +native per-agent *visibility* scoping** of project/personal skills — a plain polecat +sees them all. So curation must come from one of these four levers: + +| Lever | What it does | Keeps it out of plain workers? | Catch | +|---|---|---|---| +| **`disable-model-invocation: true`** (skill frontmatter) | *"removes the skill from Claude's context entirely"* — description gone, body loads only on explicit `/name` | **Yes** (description not in context) | **Not auto-invocable and not `skills:`-preloadable.** Must be invoked by name. | +| **`skillOverrides`** (settings, `.claude/settings.local.json`) | per-skill `on` / `name-only` / `user-invocable-only` / `off`; the `/skills` menu writes it | Yes (`name-only` trims, `off` hides) | Local settings, not committed-with-the-skill; **does not affect plugin skills**. | +| **Plugin, disabled by default** | a disabled plugin's skills cost **zero** context; enable per-persona | **Yes** until enabled | Enable is **session-wide / all-or-nothing**; enabled plugin skills are globally visible and **not** affected by `skillOverrides`. | +| **Subagent `skills:` preload** (Q2) | process-skills enter the **persona-subagent's** isolated context only | **Yes** (never in main/plain context) | Persona must be a subagent; preloaded skill cannot be `disable-model-invocation`. | + +**Capability vs. visibility — do not conflate (a likely operator trap).** +`allowed-tools` on a skill scopes **what the skill may do** (pre-approves tools while +active); it does **not** scope **who sees** the skill. Visibility is governed by +`disable-model-invocation` / `user-invocable` / `skillOverrides`, not `allowed-tools`. +(`user-invocable: false` only hides from the `/` menu — the description stays in +context and the Skill tool can still invoke it.) + +**The central tension for the persona model.** The epic's rule is *"a persona's +process-skills ride with the persona; a plain polecat stays minimal."* The docs give +two clean ways to honor it, and they pull in opposite directions on one field: + +- **Path A — Persona = subagent, process-skills preloaded.** Keep process-skills as + normal (model-invocable) project skills and `skills:`-preload them into the + persona-subagent. Isolation is automatic for the *persona's* context. **But** because + they remain normal project skills, their descriptions still sit in every plain + worker's context — so pair this with `skillOverrides: name-only|off` (local settings) + to suppress them from plain workers. Slightly clunky (settings-side, not + committed-with-skill), but fully documented. +- **Path B — Persona + process-skills as a disabled-by-default plugin.** Grouping + + namespacing + zero-cost-when-disabled, all in one unit; enable for the persona + context. **But** enabling is session-wide (no per-agent gate) and plugin skills + ignore `skillOverrides`. A persona-subagent shipped in the same plugin can preload + the plugin's skills. +- **Path C — `disable-model-invocation: true` on every process-skill.** Out of + everyone's context; invoked only by explicit `/name`. **But** then they are **not** + `skills:`-preloadable and **not** auto-selectable, so the persona's identity skill + must explicitly tell the agent to invoke each process-skill by name (`/`) at the right moment. + Maximum thrift, most manual. + +These are genuine trade-offs, which is why the epic routed them back for discussion. +A reasonable default to put in front of the operator: **Path A** when personas are run +as subagents inside Gas City (matches the existing agent model and the `skills:` +primitive), falling back to **Path B (plugin)** if/when personas need to be distributed +across rigs or toggled as a unit. Recommendation only — not a decision. + +**Local prior art worth flagging.** This rig already hit a sharp edge here: +agent-local skills are SourceDir-keyed, and the gc-toolkit importer overlay can +manufacture a colliding *phantom* agent (a compose error) when trying to scope a skill +to an imported agent (memory: *skill-scoping-imported-agents*). That is a Gas City +import-layer concern, **not** a documented Claude Code feature — so per-agent skill +scoping via the importer should be treated as unsupported/fragile, and the Path A/B/C +options above (native frontmatter + plugins) are the load-bearing mechanisms. + +--- + +## Q4 — The assume-persona entry point (load a persona-skill in plain claude) + +**In-session, two documented ways to load a skill**, both of which load the same +SKILL.md body and **persist for the rest of the session**: +1. **User invokes `/skill-name`** (the directory name is the command). +2. **Claude auto-selects** on `description` match — unless the skill is + `disable-model-invocation: true`. + +So the lightweight "assume persona X" in a plain session is simply +**`/persona-x`** (the persona's identity skill); its body — the always-on identity — then +rides the rest of the session. + +**There is no bare `claude --skill X` flag** to boot a fresh session already wearing a +skill. But there **is** a documented "boot-as-an-identity" path, which the first-pass +research under-reported: + +- **`--agent ` / the `agent` setting** runs a **subagent as the main session**. + That agent definition can: + - **`skills:`-preload** the persona's process-skills (Q2), and + - carry an **`initialPrompt`** — quoted: *"Auto-submitted as the first user turn when + this agent runs as the main session agent (via `--agent` or the `agent` setting). + Commands and skills are processed. Prepended to any user-provided prompt."* + So `initialPrompt` can invoke the persona identity skill via its `/persona-x` command (or seed the first + task) at boot. + +That combination — an agent definition whose body is (or loads) the persona identity, +whose `skills:` preloads the persona's processes, and whose `initialPrompt` kicks the +first turn — **is** the cleanest documented "assume-persona at startup" for Claude Code, +routed through an *agent* rather than a bare skill flag. It dovetails with Gas City's +existing agent model. + +**Other surfaces (documented, lesser fits):** +- **Headless `claude -p`:** include `/skill-name` in the prompt string to trigger it; + `--append-system-prompt` appends **raw text**, not a skill (bypasses the skill + machinery — usable to hardcode identity, but you lose skill packaging/versioning). +- **Agent SDK (supplementary, from the SDK skills page):** skills are + filesystem-discovered; `setting_sources` must include `user`/`project`; a `skills` + option selects which are available; invocation is model-driven — no programmatic + "force this skill at startup." Flagged as SDK-doc-sourced and less central to the + Gas City use case. + +**Persona implication.** Two entry points, pick per situation: +- **Switch within a live plain session** → invoke the persona identity skill (`/persona-x`). +- **Spawn an agent that *is* the persona** → an `.claude/agents/` definition (or the + `--agent` boot path) with `skills:` preloads + `initialPrompt`. This is the natural + home for the epic's "an AGENT = a persona instantiated as a standing/addressable + instance." + +--- + +## Synthesis — how the four answers wire into the persona model + +`docs/personas.md` asserts: *a persona IS a skill; a persona = tight always-on +IDENTITY + advisory OWNS + PROCESSES (each a skill); identity is portable; an AGENT = +a persona instantiated as a standing instance; curate skills per consumer, NOT global.* +The mechanics land as: + +- **"A persona is a skill" → yes, mechanically.** The identity is one `SKILL.md`; + invoke it by name (`/persona-x`) to wear it; it persists for the session. ✔ +- **"Processes are skills that ride with the persona" → use the subagent `skills:` + preload (Path A) or a per-persona plugin (Path B).** Native per-agent *visibility* + scoping of plain project skills does **not** exist, so "ride with the persona, not + global" is achieved by preload-into-the-persona-subagent and/or plugin gating, with + `skillOverrides` trimming any process-skills that must remain plain project skills. ✔ (with the Path-A/B/C trade-off for the operator) +- **"An AGENT = persona as a standing instance" → `.claude/agents/.md` with + `skills:` + `initialPrompt`, bootable via `--agent`.** ✔ +- **"References/knows fold INTO process-skills (self-contained)" → supported.** A skill + directory bundles its own reference files, lazy-loaded via `${CLAUDE_SKILL_DIR}`. ✔ +- **Grouping caveat to carry into the doc:** there is **no nested skill-dir grouping** + within one `.claude/skills/`; persona grouping is a **naming convention** or a + **plugin boundary**, not a directory tree. + +### Open questions to settle with the operator (before folding into docs/personas.md) +1. **Persona runtime form:** subagent-preload (Path A) vs. per-persona plugin (Path B) + vs. manual `disable-model-invocation` (Path C) — pick the default; they trade + isolation vs. distributability vs. thrift. +2. **Plain-worker thrift:** are we willing to manage `skillOverrides` in settings to + keep Path-A process-skills out of plain polecats, or does that push us to Path B? +3. **Distribution:** do we ever target >1 framework / cross-rig persona sharing? If yes, + Path B (plugin) earns its weight; if no, Path A is lighter. +4. **The `disable-model-invocation` ↔ preload exclusivity** is a hard constraint to + encode in whatever convention we adopt — a process-skill cannot be both "hidden from + plain context" and "preloaded into the persona-subagent." Decide per-skill class. + +## Uncertain / not documented +- **Per-agent skill *visibility* scoping** (a skill seen only by persona X, hidden from + all others, without plugins/settings) is **not** a documented native feature. The + closest primitives are `skills:` preload, plugin gating, and `skillOverrides`. +- **Precedence when the same skill name exists in both a root `.claude/skills/` and a + nested package `.claude/skills/`** is not spelled out (likely nearest-wins; untested). +- **`skillOverrides` interaction with subagent `skills:` preload** — whether a + `name-only`/`off` override suppresses a skill that a subagent then preloads — is not + documented; assume preload still injects the body (preload reads the skill set Claude + can invoke, and only `disable-model-invocation` is documented to block it). +- **SDK force-invoke at startup** — no documented API to start an SDK agent already + carrying a specific skill (only `setting_sources` + a `skills` selection); treat the + SDK section as supplementary. +- The **canonical docs host** served as `code.claude.com/docs/en/…` on 2026-06-14; + `docs.claude.com` mirrors it.
