Línea de trabajo

Lee .github/workflows/shared/control.md y localiza el paso “Resolve CAO GitHub read scope”. Combina sus tres redirecciones de GITHUB_OUTPUT en una sola redirección agrupada; después, compila los workflows y comprueba que se hayan resuelto las apariciones repetidas de SC2129 y que los archivos de bloqueo generados sigan siendo producidos por el compilador.

Descripción

cao-evolution cao-evolution:compiler-security

gh aw compile of all 70 workflow sources (70 generated lock files) in githubnext/gh-aw-cao failed (exit code 1) under the full validation/lint/container/security-scanner suite. One target-owned actionable finding remains: a shellcheck style warning (SC2129) repeated 59 times, all tracing to the same shared Resolve CAO GitHub read scope step in .github/workflows/shared/control.md. All other findings — 345 compiler expression errors for undefined daily_ai_credits_* activation outputs, 80 SC1003 shellcheck hits in the generated "Execute Pi CLI" step, 3 Runner-Guard findings (RGS-005/012/019) in compiler-generated router and hosted-health scaffolding, and 1,252 Grant license-policy violations plus multiple High/Critical Grype CVEs in 9 upstream container images (alpine, ghcr.io/github/gh-aw-firewall/*, ghcr.io/github/gh-aw-mcpg, ghcr.io/github/gh-aw-node, github-mcp-server, node:lts-alpine) — are compiler-generated or upstream-image findings with no corresponding editable target source, so they are kept only as bounded context. Grant license-policy evidence is available (.grant.yaml present). Highest-severity target-owned finding: Low (shellcheck style, SC2129).

Action: Assign this issue to Copilot using Agent prompt below; review its pull request and merge only after rerunning the full compiler and security scan confirms that the target-owned actionable findings are resolved.

Agent prompt
  1. Assign this issue to Copilot.
  2. Configure its MCP client to launch gh aw mcp-server over stdio from the target repository, then give it the prompt below. Require the server's fix and compile tools; never allow direct edits to generated .lock.yml files.
  3. Review the resulting pull request and rerun the same full compiler and security scan before merge. Require the target-owned actionable findings to be resolved; separately retained upstream-owned or unavailable evidence does not authorize target changes. If a target-owned finding needs human action, require the agent to stop and explain it.

Agent prompt

Fix only the target-owned actionable gh-aw compiler and security findings identified in this issue. Change only .github/workflows/*.md sources and directly related target-owned files; never edit generated .lock.yml files. Specifically: in .github/workflows/shared/control.md, combine the three sequential echo "owner=$owner" >> "$GITHUB_OUTPUT" / echo "repository=$repository" >> "$GITHUB_OUTPUT" / echo "full_name=$owner/$repository" >> "$GITHUB_OUTPUT" lines in the "Resolve CAO GitHub read scope" step into a single { ...; } >> "$GITHUB_OUTPUT" block to resolve shellcheck SC2129. Use the gh-aw MCP server's fix and compile tools, rerunning compilation with strict validation, model checks, actionlint, shellcheck, yamllint, zizmor, poutine, runner-guard, grant, grype, and syft until the target-owned findings are resolved. Review generated lock-file diffs and preserve existing behavior. Do not add or change .grant.yaml unless a separately reviewed target license-policy decision already requires it. Do not rebuild, modify, or make dependency decisions for upstream images or components; leave upstream-owned context (compiler-generated daily_ai_credits_* activation outputs, SC1003 in "Execute Pi CLI" scaffolding, RGS-005/012/019 findings in compiler-generated files, and all Grant/Grype container-image findings) unchanged and stop with a concise ownership explanation if the remaining finding cannot be fixed safely in this repository.
