Review of accessibility-scanner and alt-text-plugin repos and their branches

[Copilot]

Review of the full workspace — both github/accessibility-scanner (core engine) and github/accessibility-scanner-alt-text-plugin (this repo) — including their branches, with a summary of each. This is a read-only review; no files were changed.

github/accessibility-scanner — core engine

• GitHub Action (@v3) that scans for a11y barriers, files issues, and assigns Copilot for AI fixes. TypeScript/ESM, Vitest, MIT, public preview.
• Sub-actions under .github/actions/: find, fix, file, auth, gh-cache; composite entrypoint in action.yml.
• Dynamic plugin system (PLUGINS.md): loads .github/scanner-plugins/*, each exporting a name + default (page, addFinding) function; selectable via the scans input.
• Release lines main/v1/v2/v3. Active branches/PRs: #242 npm plugin loading, #241 AccessLint scan engine, #224 ignore_https_errors, #223 SPA networkidle wait, plus smockle/*, lw/*, and copilot/fix-github-actions-workflow* housekeeping.

github/accessibility-scanner-alt-text-plugin — this repo

• npm-distributed plugin (@github/accessibility-scanner-alt-text-plugin v1.0.0) flagging low-quality alt text, complementing Axe's image-alt.
• index.ts exports name = 'alt-text-scan' + default altTextScan({page, addFinding}), matching the scanner's plugin contract; config loaded once from .github/scanner-plugins/alt-text-scan/config.json.
• Pipeline: src/extract.ts (filters decorative/hidden/non-img) → src/rules/* → src/findings.ts. Rules: missing, vague, filename, repeated, placeholder.
• Active branches/PRs: Add repository field to fix provenance validation on publish #49 repository field for npm provenance (unblocks v1.0.0 republish), Implement copilot quality alt #38 model-backed alt-text-quality rule, taarikashenafi/* rule features, and github-advanced-security/security-review-code-scanning* runs.

How they fit together

The scanner hosts the engine and issue/fix workflow; the alt-text plugin plugs in via scans. Integration is in flight now — scanner #242 (npm plugin loading) pairs with plugin #49 (provenance fix) and the v1.0.0 release. Both share conventions: TypeScript/ESM, Vitest, ESLint + @github/prettier-config, Node ^22.13 || ^24 || ^26, MIT, and a common addFinding model.
