Conciseness

The ~27-line body is lean and assumes Claude's competence, with concrete tool calls and no padding or explanation of known concepts, matching the 'every token earns its place' anchor.

Actionability

Provides fully executable, copy-paste-ready tool calls with exact arguments (e.g., build_or_update_graph_tool(full_rebuild=True)) covering first build, full, and incremental cases, matching the 5 anchor.

Workflow Clarity

Steps are clearly sequenced with a state check and status report (ok/partial/error) as a checkpoint, but no explicit error-recovery feedback loop, fitting the 4 anchor rather than the validate-and-retry 5.

Progressive Disclosure

Under 50 lines with no need for external references and well-organized into Steps, When to Use, and Notes sections, satisfying the simple-skill exception for a 5.

Specificity

Names several concrete actions — 'Build or update the code review knowledge graph' and 'Run this first to initialize' — with only minor gaps in coverage, fitting the 'lists several specific actions' anchor rather than the comprehensive 5.

Completeness

Clearly states what ('Build or update the code review knowledge graph') and when ('Run this first to initialize, or let hooks keep it updated automatically'), but the trigger guidance could be more explicit, matching the 4 anchor rather than a concrete 'Use when...' 5.

Trigger Term Quality

Good keyword coverage ('code review knowledge graph', 'initialize', 'hooks') but missing common synonyms or file extensions, so it sits below the comprehensive 5 anchor.

Distinctiveness Conflict Risk

Targets a clear niche ('code review knowledge graph') with distinct triggers and minimal overlap risk with other skills, matching the 5 anchor.
