Conciseness

The body is operational throughout with no conceptual padding, but the "$roborev-review [commit] [--type security|design] [--panel <name>|none]" syntax is repeated three times (Usage, Instructions header, invocation line) and the IMPORTANT/guidelines meta-commentary could be trimmed. This fits anchor 4 ('minor instances of over-explanation that could be trimmed') rather than 3, since nothing explains concepts Claude already knows.

Actionability

Fully executable copy-paste commands are given for both cases ("roborev review --wait [...]" and the heredoc + "git rev-parse --verify --end-of-options \"$commit^{commit}\"" validation), with concrete error-recovery suggestions ("roborev status", "roborev init") and worked examples including job IDs. This matches the top anchor.

Workflow Clarity

Four clearly sequenced steps with an explicit validation checkpoint ("|| exit 1" ref check plus "Do not proceed") and error-path handling in step 3, matching anchor 4 ('clear sequence with most checkpoints present'). Not 5 because a validation failure simply aborts — there is no fix-and-retry feedback loop or checklist.

Progressive Disclosure

No bundle files exist and the ~130-line body is well organized under clear section headers with a 'See also' section for sibling skills, fitting anchor 4 ('good structure; most content is appropriately placed'). Not 5: the skill exceeds the under-50-line simple-skill exemption, and the Examples and Panels sections are inlined content that could live in reference files.

Specificity

"Use only when the user explicitly invokes $roborev-review" states no concrete capability at all — it never says the skill runs a code review, presents verdicts, or handles commits/panels. This matches the 'Entirely vague; no concrete actions' anchor; it cannot be a 2 because unlike 'Processes PDF files' it does not name even a minimal action or domain.

Completeness

The 'when' is explicit ("only when the user explicitly invokes $roborev-review") but the 'what' is entirely missing — the description never says what the skill does. This fits anchor 2 ('only when is present without what') and cannot be 3, which requires a clear 'what'.

Trigger Term Quality

The only trigger token is the literal "$roborev-review" invocation; natural phrases users would actually say ("code review", "review this commit", "security review") are absent. It is above a 1 because the invocation token is explicit and meaningful, but it lacks any synonyms or natural-language variants.

Distinctiveness Conflict Risk

Restricting activation to explicit invocation ("Use only when the user explicitly invokes $roborev-review") creates a distinct niche with minimal conflict risk — the skill cannot fire on generic requests. This matches the top anchor exactly.
