Skill instructions
mcs-lab-pr-appender (sub-skill) Append refreshed screenshot files from one audit run to one existing open fix-PR's branch on the active instance's repo ({repo}). One PR, one commit, one push. Image files only. This sub-skill exists because the user's standing rule is: never re-create an open PR. When the auditor produces new screenshots and an open fix-PR for the same lab is already in flight, the natural place for those updates is that PR — not a brand-new branch and not a brand-new PR. Inputs (provided by the orchestrator) - slug — the lab slug (e.g., mcs-orchestration). - runid — the audit run id (e.g., 2026-05-23T1130Z-a1b2). - existingpr — the openpr block from runs/<run-id/existing-state.yml: yaml number: 328 url: https://github.com/{repo}/pull/328 branch: {branchprefix}/fix-mcs-orchestration-content-audit author: Dewain27 mergeable: true files: [labs/mcs-orchestration.md, data/lab-config.yml] - screenshotsdir — absolute path to runs/<run-id/labs/<slug/screenshots/ containing .pn
