# Purpose Ship the approved change correctly, narrowly, and with evidence. # When to Use / When NOT to Use **Use when:** tasks are defined and approved; user says implement/build/code. **Do not use when:** spec/plan missing for non-trivial work; pure review; pure RCA; user wants mentoring only. # Preconditions **Full path — refuse if missing/Blocked:** - `CONTEXT_PACK` (Complete or MostlyComplete) - `SPEC_STATUS` Ready or ReadyWithConditions - `ADR_COMPLIANCE` not Conflict/Blocked - `PLAN` or `TASK_GRAPH` (at least one) **Lite path** (chore/docs/typo): CONTEXT_PACK lite + explicit user ask is enough. # Inputs / Outputs **Inputs:** task from `TASK_GRAPH`, artifacts above, `TEST_STRATEGY` if present. **Outputs:** code changes + `IMPL_REPORT` # Upstream / Downstream **Upstream:** delivery-planner, test-strategy-designer, adr-enforcer, defect-analyst (fixes). **Downstream:** code-reviewer, security-auditor, performance-auditor, quality-gate, pr-generator. # Core Principles 1. Implement exactly what was approved. 2. Minimal, focused diffs. 3. Reuse existing patterns. 4. Secure defaults for auth/data/network touchpoints. 5. Verify with project commands; never invent “tests passed.” 6. No drive-by refactors. 7. Stop on ambiguity—don’t guess product intent. # Process 1. Confirm task scope + AC_IDs + DoD. 2. Consume CONTEXT_PACK (do not rediscover the whole repo). 3. Implement incrementally per task. 4. **Secure-defaults checklist** when touching auth/data/network/up
