Conciseness

The body is lean and assumes Claude's competence (no concept explanations, every sentence adds non-obvious setup knowledge), but it embeds time-sensitive version numbers ("glab v1.94.0 or later", "v0.126.0 to v0.130.x") outside any deprecated/old-patterns section, and these partially duplicate the frontmatter compatibility field — a direct penalty trigger under the rubric's version-number guideline, so it cannot be a 5.

Actionability

All guidance is fully executable and copy-paste ready — "!`glab orbit skills get orbit`", "orbit skills get orbit" for the standalone binary, and "glab orbit skills get orbit <path>" for fetching referenced files — with concrete per-failure-mode actions (upgrade glab, upgrade the Orbit CLI to v0.131.0+, ask the user before installing).

Workflow Clarity

The load-then-verify flow has an explicit validation checkpoint ("If the block above is not a skill (it should begin with `---`)"), and enumerated error-recovery branches for each failure mode (manual rerun, standalone binary, version upgrade, ask-before-install) form a genuine feedback loop; no destructive or batch operations exist to trigger the validation cap.

Progressive Disclosure

This is a sub-50-line wrapper skill with no need for external references, and its sections are well organized; it even signals navigation into the loaded skill's bundle ("Links such as `references/recipes.md` ... Print them with `glab orbit skills get orbit <path>`"), which satisfies the simple-skill exception for a top score.

Specificity

The description lists several concrete actions — "search code and read it with callers and tests", "reads MRs, issues, and failed jobs with the code they cite", and "Graph queries answer relationship and aggregation questions" — which goes beyond the 1-2 actions of a score-3 anchor, but coverage has minor gaps (e.g., no concrete examples of what a search or graph query returns), so it falls short of the comprehensive coverage of a 5.

Completeness

The "what" is clearly stated, and "Skip it for writes that `glab` handles" provides explicit trigger guidance by defining the read/write boundary, so this is above the weakly-implied-when of a 3; however, there is no positive "Use when..." clause with concrete trigger phrases, keeping it below a 5.

Trigger Term Quality

Natural phrases users would say are present ("search code", "MRs", "issues", "failed jobs", "graph queries", "GitLab"), giving good keyword coverage, but common variations are missing — "merge requests" is only abbreviated, and terms like "knowledge graph", "call graph", or "callers of a function" never appear.

Distinctiveness Conflict Risk

The description occupies a clear niche tied to a specific tool ("Orbit (`glab orbit` or `orbit`)" with GitLab-specific triggers like MRs, failed jobs, and graph queries) and even disambiguates itself from plain `glab` write commands, so conflict risk is minimal.
