Audit CI

Produce a repeatable cold-CI profile, explain what controls wall-clock completion, and turn the evidence into prioritized, testable recommendations.

Required context

1. Read the repository AGENTS.md.
2. Read projects/internals/BUILD.md.
3. Inspect the current root ci:profile script and projects/internals/ci/ci-profile.js. Treat the script as the profiling source of truth.
4. Read a project's DEVELOPMENT.md before running project-specific commands when that file exists.

Do not copy profiling logic into this skill. Update the repository profiler when its behavior needs to change.

Choose the workflow

• Run a new profile when the user asks to rerun, benchmark current changes, refresh an audit, or verify an optimization.
• Analyze existing .metrics/ci-profile.{json,md} artifacts without rerunning when the user asks only for interpretation and the artifacts match the intended commit and worktree state.
• Create recommendations without implementing them unless the user also asks for the changes.
