Activation Contract
Load when the frontmatter trigger terms apply to a defect workflow.
This skill guides public collaboration. It does not grant issue approval, label, review, exception, or merge authority.
Hard Rules
- Check the user-owned RDD kill switch first. When disabled, do not start receipt reviews or fabricate approval; follow ordinary policy and report
disabled/unmanaged. - Require an approved issue (
status:approved) and clean currentmainreproduction before implementation. Audit existing PRs for supersession or conflict; stop or narrow stale claims. - Group by causal authority invariant. Use one issue and one PR or explicit chain per independent invariant and rollback boundary. Split independent causes; never merge a superseded or conflicting authority line.
- Inventory every operator flow claimed by the issue or PR, including entry, mode, environment, expectation, and negative controls. Require one truthful black-box bench journey per CLI or lifecycle flow, or actual runtime E2E proof when the core bench cannot represent it. Synthetic proxy coverage never proves another runtime.
- Use CodeGraph-first impact mapping, a dedicated worktree, and behavior-first tests. Run source-mutating normalization before candidate freeze.
- Forecast authored changes before edits. The hard limit is 400 additions plus deletions; above it, STOP for a chain or explicit maintainer-approved exception.
- Only when RDD is enabled, bind the review candidate identity, lineage, correction, and recovery records exactly. Keep bounded review defects in one correction transaction; ordinary repository policy decides delivery.
- Require independent read-only candidate validation before publication. Validation cannot edit source or authority; findings require a new candidate.
- Keep communication humane and evidence-based. Repository labels and workflow metadata are maintainer-owned, never evidence of contributor blame.
Decision Gates
| Condition | Action |
|---|---|
| RDD disabled | Ordinary policy; disabled/unmanaged; no receipt or approval claim. |
| Issue gate or reproduction fails | Wait, stop, or narrow with evidence. |
| Invariant or rollback is independent | Separate issue and authoritative PR line. |
| Core bench fits / does not fit | Bench journey / actual runtime E2E; never proxy. |
| Forecast exceeds 400 lines | Chain or approved exception before edits. |
Execution Steps
- Check mode, approval, PR conflicts, and current-main reproduction.
- Name invariant and rollback; isolate the worktree; CodeGraph-map code, tests, evidence, docs, distribution, and registration.
- Inventory flows and controls; add failing tests and the smallest correction.
- Normalize, enforce budget, run tests, and record each flow's exact candidate, command, scenario, and result.
- Freeze, validate read-only, and give the verdict, evidence, and one humane next action.
Output Contract
Return rddmode, issuepr, causalinvariant, operatorflows, journeyruntimeevidence, changedlinebudget, tests, rollback, and unresolvedauthoritydecisions.
Identify approved and superseded/conflicting authority lines; every flow, negative control, and candidate-bound proof; additions plus deletions and chain/exception; test results; independent rollback; and unresolved maintainer decisions.
