Conciseness

Nearly all content is project-specific convention Claude cannot know (row schema, append-only rules, .context/ prohibition, validator semantics) with no padding explaining known concepts, but the append-only and .context/ rules are restated across Prerequisites, Workflow, Anti-Patterns and Troubleshooting, and the Mindset section carries philosophical prose ('An unenforced rule that's actually followed is worth more here...') that could be trimmed — efficient with minor over-explanation, not the lean top anchor.

Actionability

Fully executable guidance throughout: exact file paths, copy-paste commands ('scripts/validate-risk-register-append-only.sh', 'scripts/validate-risk-register-schema.sh') with expected output and exit codes on success and failure, a fully specified column table with enums and date formats, and a troubleshooting table mapping each error to a specific fix.

Workflow Clarity

Both add and resolve workflows are numbered with explicit validation steps ('Run both validation scripts and confirm each prints no error output and exits 0 before committing'), a Definition of Done checklist, and error-recovery feedback loops in Troubleshooting ('fix and re-run before committing', 'update validate-risk-register-schema.sh's expected_fields') — a clear match to the top anchor.

Progressive Disclosure

The body is a well-organized overview with a References table giving topic, path, and 'When to Use' for two one-level-deep reference files (both verified to exist in the bundle), plus correctly placed template/schema/script assets; not below 5 because no content that belongs in a separate file is inlined and no reference is nested.

Specificity

Names the concrete artifact ('docs/RISK_REGISTER.md, the living, append-only list of every deferred item, interim shortcut, and open architecture decision') and the add/resolve operations, but the operations are conveyed through use-conditions and trigger phrases rather than stated as explicit capability actions, leaving a minor coverage gap versus the comprehensive anchor.

Completeness

Explicitly answers what ('Maintain docs/RISK_REGISTER.md, the living, append-only list...'), when ('Use when a shortcut is taken, a decision is postponed, a follow-up is filed, or an existing entry is actually resolved'), when not (three DO-NOT clauses), and includes concrete trigger phrases — a clear match to the top anchor.

Trigger Term Quality

An explicit Triggers list gives natural phrases a user would actually say ('add to risk register', 'log this as a risk', 'track this shortcut', 'this is a known gap', 'mark risk #N resolved', 'what's still open') plus synonyms for both querying and mutating the register; not below 5 since no common variation is missing, and not above because 5 is the scale maximum.

Distinctiveness Conflict Risk

Clear niche with explicit routing away from the nearest neighbors ('use adr-capture instead', 'use context-file / the local scratch-notes directory instead') and distinct, register-specific triggers; minimal conflict risk.
