shepherd

name shepherd description Use when asked to shepherd, babysit, monitor, or poll open pull requests or merge requests, including triaging review feedback, CI failures, and routine follow-up. disable-model-invocation true Shepherd Core principle Keep an authorized PR or MR moving with evidence, not noise: poll, act on new actionable items, batch each target's local fixes into one push, then resolve addressed threads. After a code-related CI failure, use full local verification as the repair loop and CI only as confirmation. Never merge without explicit authority. Do not start persistent polling for a one-off inspection, no open targets, or an action requiring human judgment; report the state and stop. Procedure Detect the platform with git remote get-url origin : use gh for GitHub and glab for GitLab. If it is ambiguous or unavailable, stop and ask. Establish targets and a handled-ID snapshot. Every external comment, review, or thread absent from that snapshot is new, including pre-session feedback. After each poll record feedback IDs, CI state, and this controller's comments. Before repeated polling, use one lowest-cost read-only evidence helper when available. Give it targets and the snapshot; require new feedback IDs, body, location, review state, non-manual CI state, failed jobs, and log references. It never mutates. Keep triage, repairs, replies, pushes, resolution, retries, and merging with the authorized controller. Poll with the platform CLI using provider commands , then compare complete review, comment, and CI state with the snapshot. Inspect failed logs only when needed. Do not reprocess old feedback or post a status-only update. Triage new evidence before remote mutation. Fix clear requests and narrow formatting, lint, compile, or test failures; answer clear questions in-thread. Escalate architectural or contradictory feedback, unfamiliar failures, non-obvious fixes, and out-of-scope conflicts. GitLab manual jobs are non-blocking unless instructed otherwise. Handle each target in its own head checkout and batch every known actionable item. Until a code-related CI failure, validate proportionately. After one, inspect its evidence, run every locally available CI-equivalent check, fix all failures, and rerun the full local suite before one repair push. Report exact checks unavailable locally instead of using CI as an iterative test runner. Reply after an addressed change or answer; resolve its thread only after the reply and required push succeed. Do not combine heads, push after every comment, resolve a local-only fix, or comment when nothing changed. Recheck CI after the verified repair push; return to step 6 on another code-related failure. Retry a suspected flaky GitLab job once without code changes; report a second failure. Poll pending checks every 2–5 minutes, active repair every 30–60 seconds, and after three or more unchanged cycles every 10+ minutes. Two unchanged cycles remain on the normal 2–5 minute cadence. Merge only when requirements and CI are green, conflicts are absent, and the user granted explicit or standing merge authority. Do not infer authority from approval. Finish or escalate Continue until the user stops monitoring, every target is merged or closed, or an escalation is needed. Report the target, current CI/review state, actions taken, and the next required human decision. Escalate immediately for ambiguous platform/target selection, an unresolved conflict, material human judgment, conflicting reviewer direction, or a failure that remains after three repair cycles.
