Scope Update

This PR now includes concrete implementation work through Phases 3-6, not just Phase 1 audit planning.

Completed in this branch

Phase 1-2 (already completed)

  • Full skills audit and prioritization
  • Trimmed all skill descriptions to spec target
  • Validator now reports 0 errors and 0 warnings for skill metadata checks

Phase 3 (implemented)

  • Enhanced scripts/validate-agents.js with:
    • --validate-urls
    • --validate-wcag
    • --skip-url-checks
  • Added markdown link checks (local + optional remote)
  • Added WCAG reference/version validation
  • Updated .github/workflows/validate-agents.yml to run strict Phase 3 checks in CI

Phase 4 (implemented)

  • Added supply-chain scripts:
    • scripts/generate-skills-manifest.js
    • scripts/generate-skills-sbom.js
    • scripts/sign-skills-manifest.js
    • scripts/check-skills-artifacts.js
  • Added workflow:
    • .github/workflows/skills-supply-chain.yml
  • Added policy:
    • .github/SECURITY-SKILLS.md
  • Added ignore rule for generated artifacts:
    • .gitignore (artifacts/)

Phase 5 (implemented)

  • Added CLI readiness workflow:
    • .github/workflows/skills-cli-readiness.yml
  • Added operations guide:
    • docs/guides/GITHUB-SKILLS-CLI-READINESS.md
  • Updated README.md with links to rollout guides and workflows

Phase 6 (implemented)

  • Added cross-platform release-readiness matrix workflow:
    • .github/workflows/skills-release-readiness.yml
  • Added release-readiness guide:
    • docs/guides/SKILLS-RELEASE-READINESS-TEST-PLAN.md
  • Kept repository-wide release consistency check advisory in this workflow to avoid blocking on existing repo-level version drift

Local validation run

Executed locally:

  • node scripts/validate-agents.js --strict --validate-wcag --validate-urls --skip-url-checks
  • node scripts/generate-skills-manifest.js
  • node scripts/generate-skills-sbom.js
  • node scripts/sign-skills-manifest.js
  • node scripts/check-skills-artifacts.js

Result:

  • Errors: 0
  • Warnings: 0
  • Info: 25 (future gh.repository metadata notices)

Notes

  • Remote URL checks are supported and can be enabled with --validate-urls (without --skip-url-checks) when network access is desired.
  • Signing is best-effort on PR/feature contexts and enforceable on protected branch contexts via workflow env/secret policy.

accesswatch and others added 12 commits March 28, 2026 09:14
Agent updates, MCP server enhancements, vscode-extension scaffolding,
documentation, and new tool modules. Work in progress.

Modified: 50 files | New: 11 files
- Rename 'A11y Agent Team' to 'Accessibility Agents' across all scripts
- Add auto-detection of installed tools (Node, Git, VS Code, Claude, etc.)
- Replace 8 individual Y/N prompts with 3-step wizard (Scope, Role, Confirm)
- Role presets: Developer, Reviewer, Content author, Full, Custom
- CLI flags bypass wizard for backwards compatibility
- Scheduled task renamed with backward-compat unregister of old name
- LaunchAgent plist renamed with backward-compat bootout of old plist
- Common detection functions in Installer.Common.ps1 and installer-common.sh
…heck, and getting started tips

- Smart scope default: auto-detect .git directory, pre-select Project or Global
- --role flag: skip wizard with developer/reviewer/author/full/custom
- --config flag: load team config JSON for unattended installs
- Default on every prompt: pressing Enter always picks a sensible choice
- Post-install health check: verify installed files with PASS/WARN summary
- Role-tailored Getting Started tips: show relevant commands for chosen role
… guard, config validation, elapsed time

install.ps1 and install.sh now support:
- --help / -Help: full usage text with all flags documented
- --version / -Version: show git commit hash and tag
- --force / -Force: overwrite existing files and bypass idempotent guard
- --quiet / -Quiet: suppress banner and informational output
- --verbose (bash): extra diagnostic output
- Idempotent guard: skip install if already up to date (use --force to override)
- Config validation: warn on unknown keys in team config JSON
- Elapsed time: display total install duration
- Enriched summary JSON: version, elapsedSeconds, healthCheck fields
- PowerShell version check: hard block below 5.1, soft warn below 7
- Bash version check: warn if bash < 4

Also adds ruff.toml to limit Ruff LSP scanning to Python directories.
Replace [x]/[ ] checkbox format with a simple dash list of tools that
are actually installed. Fixes PowerShell array-flattening bug where
nested @() arrays were iterated as individual elements, producing
garbled single-character names and raw True/False values.
Ports the complete Codex CLI support from install.sh:
- Copies AGENTS.md, config.toml, and roles/*.toml files
- Supports both project (.codex/) and global (~/.codex/) install
- Merge-ConfigFile preserves user content in AGENTS.md and config.toml
- Adds Codex to post-install summary with paths displayed
- Adds codex to InstallSummary.installed and .destinations JSON
- Manifest entries for config, roles, and scope tracking
- install.ps1: add chat.agentFilesLocations to exclude .claude/agents/ from Copilot picker
- install.ps1/install.sh: deploy .claude/AGENTS.md team workflow config
- update.ps1: add Codex CLI update section (AGENTS.md, config.toml, roles)
- update.ps1/update.sh: add .claude/AGENTS.md and Gemini extension update
- uninstall.ps1: enhance Remove-OurSection with toml marker support
- uninstall.ps1: expand Codex cleanup (config.toml, manifest paths, roles)
- uninstall.ps1: add Codex entries to fallback manifest builder
- docs/deployment-layout.md: comprehensive file placement guide for all 6 tools
- docs/getting-started.md: cross-reference to deployment layout doc
- update.ps1: add Repair-PriorInstall with 6 repair items (R1-R6)
  R1: patch chat.agentFilesLocations in VS Code settings.json
  R2: deploy missing .claude/AGENTS.md
  R3: migrate legacy marker strings to a11y-agent-team
  R4: reconcile manifest for Codex and Claude entries
  R5: remove stale files no longer in current repo
  R6: migrate legacy central store ~/.accessibility-agents/
- docs/deployment-layout.md: add VS Code Settings Changes appendix
  with full rationale, platform paths, verification, and revert steps
- docs/configuration.md: add Agent Discovery Settings section and
  duplicate agents troubleshooting entry
- docs/troubleshooting.md: add Duplicate Agents in Picker symptom
- docs/getting-started.md: cross-reference to settings documentation
…detection

After choco installs verapdf or java, the installer session PATH is stale
so Get-Command verapdf/java returns null even though the binary is present.

- Use env:ChocolateyInstall (set by Chocolatey itself) instead of hardcoded
  ProgramData path -- short-circuits cleanly when Choco is not installed
- Add session PATH refresh after winget install Java and choco install verapdf
- Add same Chocolatey fallback probe in Show-PdfDeepValidationReadiness,
  Show-McpCapabilityReadiness, and the end-of-install inline check
- Remove stale Restart your terminal messages now that in-session refresh works
