# id-document — generate/update the change documentation from the recorded plan step-report note (infra-delivery step 16) The `infra-delivery` step sequence (a documented procedure this skill family forms — no workflow engine or state-machine file ships) drives an infra change → merge. `id-document` is the **documentation step** (step 16). It is a **doc-output PROCEDURE skill** the generic agent runs to **generate or update the change documentation** a delivered IaC change requires — the **change-record (an ADR: what changed + why)**, the **blast-radius summary**, the **runbook**, the **rollback note**, and the **changelog** entry — **DERIVED from the recorded pre-merge plan step-report note + the plan summary** and **MATCHED to the surrounding repo's existing doc conventions** (where docs live, the changelog format, the ADR style). It reads the recorded plan observation **as DATA** and produces docs; it **NEVER** mutates infra, re-runs the plan, edits any verdict, or flips the workflow's `document` step. ## ADVISORY — not a gate, read-only, derived-from-recorded-evidence (the safety invariant) This skill is **ADVISORY**, **read-only**, and **derived-from-recorded-evidence**. It is a mistake-catcher **FOR** the trusted operator — it surfaces a missing change-record / stale runbook / absent rollback note / changelog-convention mismatch. It does **NOT gate, approve, merge, or block**; **the merge floor** (the adopter's branch protection + CI checks — see `docs/merge-floor.md
