+name: implement-data-code
+description: Improve SQL, Spark, ETL/ELT, CDC and pipeline implementation code while preserving data grain, keys, correctness and replay safety.
+---
+
+# Implement Data Code
+
+Use this skill only for its stated purpose. Follow the shared source-of-truth, permission and evidence rules in `../../references/workflow-contract.md`. Read `../../references/data-code-contracts.md` for detailed method when necessary.
+
+## Procedure
+1. Map source/output grain, keys, joins, null handling, ordering, schema and downstream consumers.
+2. Check duplicates, CDC merges, retry/idempotence, replay windows and late/deleted events.
+3. Implement minimal transformation or pipeline fix; avoid DISTINCT as a band-aid.
+4. Add representative quality and reconciliation tests including repeat/replay cases.
+5. Profile for tuning only after outputs are proven correct.
+For full data-platform incident programs, advise appropriate specialized scope rather than overstating this coding skill.
+
+## Handoff rule
+State actual artifacts or grounded code findings and validation status. Never invent file paths, executed tests, tool access, or completed subagent work. Keep output proportionate to the user request.
