# Verify Manifest Coverage ## Purpose Cross-check a Review artifact's declared `manifest_ids` against the actual diff it is reviewing. Catches scope creep at Review — before it reaches Ship — rather than discovering the mismatch after release. This is a power skill, not a lifecycle phase. It is gate-bound: it runs at every Review Exit Gate. ## Invocation Context Use this skill when: - Review is finalizing its findings and about to set `manifest_ids` in its own frontmatter - Review needs to confirm the diff it examined actually corresponds to the IDs it is claiming coverage for Do not invoke it before Review has an actual diff to compare against (i.e., not during Think or Plan). ## What To Load **Foundation** (confirm in context; load if not already present): - Root `AGENTS.md` - `workflow/router.md` - `workflow/lifecycle.md` - `workflow/rules.md` **Minimum for invocation**: - This file - `references/output-schema.md` **Before starting work**: - `references/coverage-comparison.md` — how to derive the diff's actual manifest coverage from the task artifact's `Changed Files` section - The task artifact's `Changed Files` section (each entry already carries manifest IDs per Build's own contract) - The review artifact's declared `manifest_ids` ## Inputs - The task artifact's `Changed Files` section (file → manifest IDs mapping from Build). - The review artifact's declared `manifest_ids` in frontmatter. - The actual diff (via `git diff` or the task artifact's file list)
