Stand up the verify→repair loop in a repository that doesn't have one: a single discoverable command per rail — format, build, test — and a CI workflow that runs the same commands. This is the action-taking sibling of agent-ready-rails: rails audits and reports that the loop is missing (its load-bearing R1/R2 finding); this skill installs it. The evidence behind why this rail matters most is in that skill's grounding — a verify loop the agent cannot skip is the single highest-leverage change for agent success.

You execute from the target repo, not from this skill's directory, so a path written relative to this skill will not resolve. Resolve the base directory once and use it everywhere — including in any subagent prompt, which must receive the literal absolute path, never a relative form:
