Conciseness

The append-only rule is restated across the Row Schema ('Permanent id, assigned once, never reused or renumbered'), workflow step 4 ('Never insert out of # order, never renumber existing rows'), resolve step 3 ('Never delete the row, never touch any column but Status/Date/Decision'), the Mindset section, and two full Anti-Pattern blocks; the .context/ citation prohibition likewise appears in both workflow step 3 and Anti-Pattern 4. Mostly efficient, but this cross-section repetition and the Mindset section's philosophical rationale ('An unenforced rule that's actually followed is worth more here than an enforced one that invites working around it') could be tightened. Not 4: the repetition spans multiple full sections, beyond 'minor instances'; not 2: each section is individually purposeful and nothing explains concepts Claude already knows.

Actionability

Fully concrete, executable guidance: 'Read the current last row's # in docs/RISK_REGISTER.md; the new row's # is that value + 1', copy-paste commands (scripts/validate-risk-register-append-only.sh, scripts/validate-risk-register-schema.sh) with expected output specified ('nothing printed, exit code 0'), a precise per-column Row Schema table, and a troubleshooting table mapping each failure mode to a specific fix. The common cases (add, resolve, pre-commit rejection) are all covered with concrete instructions.

Workflow Clarity

Both add and resolve workflows are numbered with explicit validation checkpoints ('Run both validation scripts and confirm each prints no error output and exits 0 before committing'; 'Re-run scripts/validate-risk-register-schema.sh and confirm it passes now that all three cells moved together'), plus a Definition of Done checklist and a Troubleshooting section providing fix-and-retry feedback loops for pre-commit rejections. This matches the top anchor's validate -> fix -> re-validate pattern exactly.

Progressive Disclosure

The body is a clear operational overview; both referenced files (references/relationship-to-sibling-conventions.md, references/unresolved-verification-case-study.md) exist, are one level deep, and are surfaced in a References table annotated with 'When to Use'. The row template and JSON schema are appropriately split into assets/templates/ and assets/schemas/, and both scripts referenced in the body exist in scripts/. Not 4: navigation is unambiguous and no content that belongs in a bundle file is inlined.

Specificity

'Maintain docs/RISK_REGISTER.md, the living, append-only list of every deferred item, interim shortcut, and open architecture decision' names a concrete artifact and the specific actions of filing ('a follow-up is filed'), resolving ('an existing entry is actually resolved'), and querying. Multiple specific concrete actions with comprehensive coverage for this skill's scope, in third-person voice. Not 4: the action coverage (add, resolve, distinguish, query) is comprehensive rather than having minor gaps.

Completeness

What: 'Maintain docs/RISK_REGISTER.md, the living, append-only list of every deferred item, interim shortcut, and open architecture decision.' When: 'Use when a shortcut is taken, a decision is postponed, a follow-up is filed, or an existing entry is actually resolved' -- plus an explicit DO-NOT-use clause with concrete trigger phrases. Both what and when are answered explicitly and concretely, exceeding the top anchor's structure.

Trigger Term Quality

Explicit trigger phrases a user would naturally say: 'add to risk register', 'log this as a risk', 'track this shortcut', 'this is a known gap', 'mark risk #N resolved', 'what's on the risk register', 'what's still open'. Covers both write-side and read-side phrasings with synonyms. Not 4: the trigger list leaves no common variation missing for this domain.

Distinctiveness Conflict Risk

'DO NOT use for accepted, finalized architecture decisions (use adr-capture instead), for session-local working notes that don't need to survive across the team (use context-file / the local scratch-notes directory instead), or for anything that must stay confidential' actively disambiguates the two nearest sibling skills with named redirects. A clear niche with distinct triggers and minimal conflict risk.
