Conciseness

The body is lean and assumes Claude's competence; it explains only the custom system specifics Claude could not know (the Deeplake mount, edge types, build behavior) and every line earns its place with no padded concept explanations.

Actionability

The path cheat sheet provides copy-paste-ready `cat` commands covering every common query type (query, find, show, neighborhood, impact, path, layers, tour), fully executable with no pseudocode.

Workflow Clarity

A clear 5-step numbered workflow sequences broad exploration → locate → relationships → flow/impact → read source, and the Anti-patterns section supplies validation guidance (staleness checks, "Incoming (0) is not dead code") appropriate for this read-only skill.

Progressive Disclosure

A single well-organized file with clear section headers and no nested references; all query paths are documented inline at one level, which is appropriate given there are no bundle files to split out.

Specificity

The description names one concrete action ("Query the local code graph") and lists several specific queryable objects (functions, classes, calls, imports), which lists several specific capabilities but is essentially a single action with minor coverage gaps rather than multiple distinct actions.

Completeness

It explicitly answers both what ("Query the local code graph...") and when ("Use when the user asks structural questions about the codebase") with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

It includes four natural quoted phrasings a user would actually say ("what calls X?", "what does Y import?", "where is Z defined?", "what is the architecture / which subsystems exist?"), giving comprehensive coverage of natural trigger terms.

Distinctiveness Conflict Risk

It carves a clear niche (AST-derived code graph via Deeplake mount for structural questions) with distinct triggers, but classic phrasings like "where is Z defined" overlap somewhat with general grep/code-search skills, so minor overlap risk remains.
