Description

Bring the resource-staleness workflow into a local maintainer canvas so resources can be inspected and acted on individually without publishing a report or changing GitHub state.

The board scans local meaningful Git history, groups skill and hook assets, and supports filtering and read-only working-tree file previews. Reviews propose concrete improvements; removal recommendations must explain which current native capability supersedes the resource rather than treating age as proof of obsolescence.

Item work is routed to isolated project child sessions, retaining and reusing each resource's child context. Reviews and preparation stay local. Publishing requires separate confirmation tied to the prepared staged-diff hash. Persistent local state and content fingerprints reject stale or cancelled results.

Type of Contribution

Additional Notes

This is a project-scoped maintainer customization under .github/extensions, not a marketplace plugin. It reuses the Open PR Board's token-protected loopback server. The scheduled staleness workflow is unchanged.

Validation:

node --experimental-vm-modules --test eng\resource-staleness-board.test.mjs: passed, 17 tests.
npm start: passed after npm ci --no-audit --no-fund restored missing dependencies; generated README and marketplace outputs remain unchanged. Existing external-plugin metadata warnings remain.
bash eng/fix-line-endings.sh: passed.
node --check .github\extensions\resource-staleness-board\extension.mjs: passed.
node --check .github\extensions\resource-staleness-board\public\app.js: passed.
git diff --cached --check: passed before committing.

The user has opened the board locally. Full child-session review/publication and extension-reload behavior have not been verified end to end. The existing open provider returned a missing POST /api/read_file route after the preview was added, consistent with an older provider process serving updated static assets; an extension reload is required to load the new server route.

Paid-service guidance is not applicable to this local maintainer customization.

What changed in this PR

Adds a project-scoped maintainer canvas for reviewing resource staleness locally, using reusable child sessions to prepare changes before separately confirmed publication. The scheduled staleness workflow remains unchanged.

Changes:

Inventories resources using meaningful Git history, grouped assets, and content fingerprints.
Adds filtering, read-only previews, persistent review state, and child-session work routing.
Documents operating boundaries and adds focused regression coverage.

File	Description
`eng/resource-staleness-board.test.mjs`	Covers inventory, persistence, work routing, HTTP endpoints, and previews.
`.github/extensions/resource-staleness-board/README.md`	Documents usage, history rules, child sessions, and publication boundaries.
`.github/extensions/resource-staleness-board/public/styles.css`	Styles the responsive board, previews, and confirmation dialog.
`.github/extensions/resource-staleness-board/public/index.html`	Defines filters, resource details, and publication confirmation.
`.github/extensions/resource-staleness-board/public/app.js`	Handles filtering, previews, live updates, and work requests.
`.github/extensions/resource-staleness-board/lib/work.mjs`	Builds child-session assignments and publication instructions.
`.github/extensions/resource-staleness-board/lib/state.mjs`	Persists reviews, work tokens, and prepared changes under a file lock.
`.github/extensions/resource-staleness-board/lib/preview.mjs`	Provides size-limited working-tree previews and binary detection.
`.github/extensions/resource-staleness-board/lib/inventory.mjs`	Groups resources, analyzes Git history, and fingerprints content.
`.github/extensions/resource-staleness-board/extension.mjs`	Registers canvas actions and connects scanning, persistence, and HTTP serving.

Regarding submission status comment #5251 (comment): Partially accepted. Fixed the codespell failure without weakening validation, and local spelling, build, line-ending normalization, and all 30 regression tests pass; the new push will rerun CI, while the required maintainer approval remains outstanding.

aaronpowell · 2026-10-23T04:38:12Z

Regarding contributor reputation comment #5251 (comment): Acknowledged as an informational maintainer-review requirement; no code change is appropriate. The contributor workflow passed with Profile MEDIUM and Credential audit NONE, and the human review remains outstanding.
