+- **READMEs:** include the consumer contract: configuration, semantics, failures, limitations, extension points, and model-visible effects. Quote stable model-visible text owned by the package; link generated catalogs and cross-package owners. Keep durable gaps and maintainer traps, not ordinary cleanup inventories. Follow the [package README contract](../../../docs/cookbook/adding-a-package.md#4-write-the-package-readme).
 - **RFCs:** retain unique rationale, mechanisms, alternatives, consequences, shipped verification contracts, and named coverage gaps. Implemented RFCs state shipped reality in the present tense; remove planning checklists, not evidence of what pins the decision.
 - **Postmortems:** retain the incident sequence, evidence, causal chain, impact, and prevention. Remove repeated persuasion or implementation detail that does not establish causality.
 - **Skills and agent instructions:** state behavioral guardrails and explicit scope limitations such as “guidance, not a script/checklist.” Keep the workflow concise and link its source of truth.
