It extends the [independent review contract](review-execution-contract.md) +and applies the ownership rules in [Code Taste](code-taste.md). It is not a +repository-wide cleanup pass. + +Adapted from DeepSeek Harness's +[`dsh-find-simplifications`](https://github.com/deepseek-ai/deepseek-harness/tree/master/.agents/skills/dsh-find-simplifications), +with repository-specific Agent Notes, Node packages, and protected seams removed. + +## Prove consumers before calling code dead + +Start with the changed or newly expanded symbol, config key, event, hook, branch, +or wire string. Use `rg` for the exact name and its call forms, then read the call +sites. Classify every consumer: + +- **production:** runtime source, loaders, registries, entrypoints, generated + dispatch, plugins, examples used as smoke paths, or external/public contracts; +- **non-production:** tests, fixtures, snapshots, docs, comments, and type-only + references; +- **ambiguous:** reflection, dynamic import, string dispatch, serialization, + compatibility shims, scripts, and examples whose production role is unclear. + +No text match is not proof of no consumer. Check exported APIs, decorators, +registries, generated code, config/wire names, and public compatibility before +proposing deletion. A strong dead-code finding names the searched surface and +shows that only non-production consumers remain, or that the branch is +unreachable from every supported ingress. + +Reject the candidate when a production caller exists and deletion would be a +feature decision, when an explicit compatibility or design contract owns it, or +when removal only moves the same complexity elsewhere. + +## Audit defensive code by trust boundary + +For every copy, freeze, validator, fallback, catch-all, rollback, or callback +capture, record: + +1. where the value or failure originates; +2. whether the boundary is trusted and typed or external and untrusted; +3. who owns it after handoff; +4. the concrete failure the defense prevents; +5. whether another layer already enforces the same fact. + +Preserve validation and ownership transfer at parsers, user configuration, +queues, model/tool JSON, durable files, workers, processes, RPC/wire decoders, +and native-resource boundaries. Same-process typed calls usually borrow their +declared values; hostile-getter tests, mutation after a documented readonly +handoff, or broad exception swallowing do not alone justify a speculative +contract. + +Call code over-defensive only when the threatened behavior is unsupported or +already owned elsewhere and the duplicate defense has a concrete cost: extra +allocation, hidden fallback, inconsistent error semantics, public API growth, +state duplication, unreachable rollback, or dedicated tests for behavior no +consumer needs. + +## Collapse duplicated lifecycle facts carefully + +For asynchronous or resource-owning code, draw the owner and transition graph. +Map each sentinel, readiness promise, cancellation flag, terminal-result guard, +disposer, rollback list, and shutdown branch to the fact it protects. + +Merge mechanisms that mirror the same liveness, readiness, settlement, or +ownership fact. Preserve distinct machinery when it separately protects partial +allocation rollback, first-terminal-outcome arbitration, callback containment, +worker/process ownership, synchronous publication, or dispose-to-quiescence. + +## Report only actionable simplifications + +Every finding must bind to a changed `path:line` and include: + +- the exact candidate and why the current diff makes it relevant; +- production, non-production, and ambiguous consumer evidence; +- trust or lifecycle ownership evidence when defensive code is involved; +- the concrete maintenance, correctness, resource, or contract cost; +- the smallest safe `DELETE`, `DEFER`, `INLINE`, `MERGE`, or `MOVE` action; +- the behavior or compatibility that the action intentionally gives up. + +Do not report typo cleanup, subjective complexity, a one-off unused local, or +"this looks defensive" without call-site and boundary proof.
