feat(config): dual-read .dz/ui-debugger/ui-debugger-mcp.json before the root file (#64) - #65
Conversation
…ot file (#64) A repo that consolidated its agent config under .dz/ could not boot the tool. The two-candidate resolution now lives in ONE place — src/config/load.ts — exported as CONFIG_CANDIDATES plus resolveConfigPath(cwd): - loadConfig / loadWorkspaceDir / configFingerprint (content, not path) all resolve through it: .dz/ first, root .ui-debugger-mcp.json as legacy fallback. - init writes the starter config at .dz/... when a .dz/ dir already exists, else at root; only-if-absent applies to whichever candidate is found. - both present -> .dz/ wins and the tool prints ONE line naming the ignored root file (init: stdout; server boot: stderr — stdout is the stdio MCP JSON-RPC channel and must stay machine-only). - a bad .dz/ copy is a ConfigError exactly as a bad root copy is; root is NOT read in that case. Schema untouched. .mcp.json snippet printing unchanged. Tests written first (red on the parent commit): candidate order, .dz-first reads, both-present notice, only-if-absent, bad-.dz-errors-without-root, and the fingerprint keying on the resolved .dz/ copy. One existing expectation updated: look.test.ts pinned the literal ".ui-debugger-mcp.json" inside visionUnavailableMessage; the message now says "the project config" since a single root filename is no longer the whole truth. Same intent (names where the vision model is set), new truthful wording — flagged here rather than smuggled in silently. Docs left true: docs/idea/config.md (Resolution order + init + config sections), src/cli/help.ts, README.md, CLAUDE.md, CONTRIBUTING.md, docs/idea/architecture.md, docs/idea/models.md, docs/reference.md.

Check that .dz is a directory before selecting the nested write path.
If .dz is a regular file and neither config exists, this returns .dz/ui-debugger/ui-debugger-mcp.json. Initialization cannot create that parent path and fails instead of using the root config. Replace this existence check with a directory check. Add a test for a file named .dz.

Issue #64 scoped the dual-read to src/config/load.ts (one place) plus its callers (init, fingerprint, main's one-line notice) and six named docs. The bare reword of every ".ui-debugger-mcp.json" mention across adapters, agent belt, mcp tool descriptions, services and two unnamed docs was a mechanical sweep that made the PR unreviewable — reverted 12 files: src/adapters/factory.ts, src/adapters/browser/launch.ts, src/agent/belt/look.ts + look.test.ts, src/mcp/tools/output.ts, src/mcp/tools/start-debug.ts, src/config/schema.ts ("schema untouched"), src/services/debug-service.ts, src/services/login.ts, src/services/session-builder.ts, docs/idea/models.md, docs/reference.md Untouched red-CI note: the session-builder auth-e2e timeout is a pre-existing flake (main run 31235917066 failed its sibling at 30009ms before this branch existed; 10/10 green on origin/main locally) — no test or timeout changes made here.

Live test PASS — 2026-09-02. status: PASS |
## What Bumps the package to 1.9.0 across all four places that carry the version (`package.json`, `server.json` top-level + `packages[0]`, and the exported `VERSION` in `src/index.ts`), and adds the 1.9.0 CHANGELOG entry covering everything merged since v1.8.0. ## Why v1.8.0 (2026-07-31) is still `dist-tags.latest` on npm and knows only `CONFIG_FILENAME = '.ui-debugger-mcp.json'` — it throws when that file is absent. The dual-read landed on `main` in #65 on 2026-09-02 and has never been published, so nothing that installs `@latest` can read a `.dz/` config. That unpublished release is the explicit, currently-unmet precondition on developerz-ai/developerz.ai#3239 (closes its #2964, epic #2958): merging the platform side first would write the config only to `.dz/`, which 1.8.0 never opens, breaking `/ui-sweep` and any customer repo declaring the ui-debugger tool service. Cutting this release is what unblocks that merge. ## Changes - `package.json` 1.8.0 -> 1.9.0 - `server.json` — both `version` fields (top-level and `packages[0].version`), which PUBLISHING.md requires be bumped alongside package.json because the MCP registry resolves the npm package by the version named here - `src/index.ts` `VERSION` 1.8.0 -> 1.9.0 — caught by the repo's own "VERSION matches package.json" test, which failed until this line moved - `CHANGELOG.md` — 1.9.0 entry: the `.dz/` dual-read (#65), the `ActResult.navigated` full-document-load signal (#62), and the biome absolute-path prune fix (#63) Minor, not patch: the dual-read is a backwards-compatible feature — the root file still resolves, and `.dz/` only wins where it exists. ## Verification Run on the branch, after `bun install --frozen-lockfile`: - `bun run lint` — 157 files checked, clean - `bun run typecheck` — clean - `bun run build` — clean - `bun test` — 1171 pass / 10 skip / 0 fail (1181 across 75 files) - `node -e "JSON.parse(...)"` on both `server.json` and `package.json` The one failure this change had to fix was found by the gate, not by reading: `bun test` reported `(fail) VERSION matches package.json` until `src/index.ts` was bumped. No test was modified. ## Post-merge Publishing is a human step and deliberately not automated here: cut a GitHub Release `v1.9.0` (or Actions -> release -> Run workflow). `release.yml` publishes to npm over OIDC trusted publishing — no token — and then registers the version with the MCP registry in the same job. Confirm `npm view @developerz.ai/ui-debugger-mcp dist-tags` reads 1.9.0 and that the published `src/config/load.ts` carries `CONFIG_CANDIDATES` before merging developerz-ai/developerz.ai#3239. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01NCugazR85MEY7B2KVpcf7F <!-- codesmith:footer --> --- <a href="https://app.blacksmith.sh/developerz-ai/codesmith/ui-debugger-mcp/pr/67"><picture><source media="(prefers-color-scheme: dark)" srcset="https://pr-comments-assets.blacksmith.sh/codesmith/view-with-codesmith-dark-v2.svg"><source media="(prefers-color-scheme: light)" srcset="https://pr-comments-assets.blacksmith.sh/codesmith/view-with-codesmith-light-v2.svg"><img alt="View with [code]smith" src="https://pr-comments-assets.blacksmith.sh/codesmith/view-with-codesmith-dark-v2.svg"></picture></a> <a href="https://backend.blacksmith.sh/track/enable-autofix?expires=1791198246&installation_model_id=11168&pr_number=67&repository=developerz-ai%2Fui-debugger-mcp&return_to=https%3A%2F%2Fgithub.com%2Fdeveloperz-ai%2Fui-debugger-mcp%2Fpull%2F67&signature=70dd7a36b08defa560625a6fb01d9e59c327f1ece4c12e43c40d7bdbb6fddaca"><picture><source media="(prefers-color-scheme: dark)" srcset="https://pr-comments-assets.blacksmith.sh/codesmith/autofix-with-codesmith-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://pr-comments-assets.blacksmith.sh/codesmith/autofix-with-codesmith-light.svg"><img alt="Autofix with [code]smith" src="https://pr-comments-assets.blacksmith.sh/codesmith/autofix-with-codesmith-dark.svg"></picture></a> <sup>Need help on this PR?

What
The tool now resolves its per-repo config from
.dz/ui-debugger/ui-debugger-mcp.jsonBEFORE falling back to the root.ui-debugger-mcp.json, so a repo that consolidated its agent config under.dz/boots the tool unchanged. The two-candidate resolution lives in ONE place:src/config/load.tsexportsCONFIG_CANDIDATESplus aresolveConfigPath(cwd)helper.Why
The
.dz/migration (parent developerz-ai/developerz.ai#2958, platform side #2964) moves per-repo agent config under.dz/; until this change such a repo had to keep a duplicate root config or the tool failed with "config not found". Nothing else in the migration depends on this, but every migrated repo hits it.Changes
src/config/load.ts— the one home for the order:CONFIG_CANDIDATES = ['.dz/ui-debugger/ui-debugger-mcp.json', CONFIG_FILENAME],resolveConfigPath(cwd)(first candidate file that exists; when none exists, the preferred write target:.dz/…if a.dz/dir is present, else root), andignoredRootConfig(cwd)(the both-exist notice).loadConfig/loadWorkspaceDirresolve through it; error messages name the actual file that failed, and the not-found error names both candidates.src/cli/init.ts—configPathcalls the helper: writes the starter config at.dz/…when a.dz/dir exists, else root; only-if-absent applies to whichever candidate is found; theworkspaceread (existingWorkspace) uses the same resolution. When both exist, init prints ONE notice naming the ignored root file.src/main.ts— server boot prints the same one-line notice on stderr (stdout is the stdio MCP JSON-RPC channel; verified 0 bytes on stdout with both configs present).src/config/fingerprint.ts— the drift fingerprint resolves throughresolveConfigPathand keys on content (identical bytes at either location are the same config; editing a shadowed root copy is not drift).login.ts,session-builder.ts,browser/launch.ts,debug-service.tsdrift message,look.tsvision-unavailable message, MCP tool descriptions).docs/idea/config.md(incl. the "Resolution order" section),src/cli/help.ts,README.md,CLAUDE.md,CONTRIBUTING.md,docs/idea/architecture.md, plusdocs/idea/models.mdanddocs/reference.mdwhich carried the same stale location claims.Schema untouched — this changes WHERE config is read from, nothing else.

src/agent/belt/look.test.tspinned the literal.ui-debugger-mcp.jsoninsidevisionUnavailableMessage; the message now says "the project config" because a single root filename is no longer the whole truth. Same assertion intent (names where the vision model is set) — updated with the code in the same commit so every commit stays green, flagged here rather than smuggled in.Verification
Tests written first and confirmed red on the parent commit (
SyntaxError: Export named 'CONFIG_CANDIDATES' not found, 5 fail), then green after the change. Full gate, all green:New coverage:
