CI Speedup

Find the stage where changes wait between push and deploy, fix that stage with numbers, and write down what changed and when to look again.

• IS: measuring where changes wait from push to deploy; a pipeline's critical path; check placement per lane and the required-check set; merge queue sizing or the post-merge design; main-health detection, attribution and revert; the agentic merge loop that reverts, re-lands and repairs without a human; flake policy; deploy throughput; cost per merged change; the ledger.
• IS NOT:
  • one PR's red build, conflict or single rerun (pr-babysitter)
  • package releases (autoship)
  • which checks exist, enforcing a rule, hook wiring, protected paths, or the sandbox rules for an unattended agent job (codebase-architecture); this skill owns the merge controller that dispatches those jobs and decides revert, merge and deploy
  • pruning tests (test-audit)
  • reviewing a workflow diff (tidy)
  • repositories with no pipeline yet (scaffold-cli, scaffold-nextjs)
  • how many agents to run, or writing the repository's merge-risk policy (this skill reads that policy; it does not author it)

The Model

The objective is X = changes merged and deployed per hour, held inside three budgets and one hard limit:
