Conciseness

The body is lean and assumes Claude's competence — it documents only the project-specific graph schema and gives terse operational directives with no filler — but the freshness-check prose in step 2 and the triple node-type enumeration could be trimmed slightly, matching anchor 4 rather than anchor 5's every-token-earns-its-place standard.

Actionability

Every step is executable: a copy-paste shell one-liner for resolving $UA_DIR, a complete copy-paste git validation block, exact JSON keys to Grep ("project", "layers", "tour"), the exact node types and fields to extract, and a named section template for the output guide — matching anchor 5 ("copy-paste ready code or commands").

Workflow Clarity

Eleven clearly sequenced steps with explicit validation checkpoints and error-recovery fallbacks: step 1 verifies knowledge-graph.json exists and tells the user to run /understand if not; step 2 resolves the graph commit, checks staleness with concrete diffs, and degrades gracefully when git metadata is missing or invalid — matching anchor 5.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent) and none are needed; the ~65-line body is cleanly organized into Graph Structure Reference, How to Read Efficiently, and Instructions, with all content appropriately inline for a skill of this size — matching the well-organized-structure criterion for anchor 5.

Specificity

"generate an onboarding guide for new team members joining a project" names the domain and one concrete action, which matches anchor 3, but the description is written in second person ("Use when you need to"), which the judging guidelines penalize by reducing the specificity score by 1. It does not reach anchor 4 since only a single action is listed.

Completeness

Both what ("generate an onboarding guide") and when ("Use when you need to...") are explicitly present, but the "when" clause largely restates the "what" instead of adding independent trigger scenarios, so it matches anchor 4 rather than anchor 5's concrete trigger phrases.

Trigger Term Quality

"onboarding guide", "new team members", and "joining a project" are natural phrases a user would say when they need this skill, matching anchor 4 ("good keyword coverage; a few natural terms missing"). It falls short of anchor 5 because variations like "onboard", "new hires", or "ramp up" are absent.

Distinctiveness Conflict Risk

"onboarding guide for new team members joining a project" is a clear niche with distinct triggers and minimal overlap with other skills, matching anchor 5; it is more specific than anchor 4's example of closely related formats sharing triggers.
