Conciseness

The body is efficient: every section carries non-obvious operational information (sandbox escalation, remote-ref recovery, panel synthesis semantics) and there is no explanation of concepts Claude already knows. Minor trimmable padding exists — the "These instructions are guidelines, not a rigid script" paragraph and some redundancy between the Usage synopsis, the header of Instructions, and the Examples — so it sits just below the 'lean and efficient; every token earns its place' anchor.

Actionability

The skill provides copy-paste-ready executable commands: the exact default invocation `roborev review --branch --wait`, a complete 30-line executable bash snippet for base-branch validation with a real recovery path, and worked examples covering the default and base+type cases. This matches the 'fully executable; copy-paste ready; specific examples cover the common cases' anchor; not 4 because there are no meaningful gaps in the guidance.

Workflow Clarity

The four-step workflow has an explicit validation checkpoint ("If validation fails, inform the user the ref is invalid and report the git error. Do not proceed."), error-recovery feedback loops for command failures (suggest `roborev status`, `roborev init`, re-run), and clear conditional handling for panels and next steps. This matches the anchor 'clear sequence with explicit validation steps; feedback loops for error recovery'; not 4 because both validation and recovery are fully present.

Progressive Disclosure

No bundle files exist and the body is organized with clear, well-ordered sections plus a See-also list, so navigation is easy. However, the ~30-line inline base-branch bash snippet is exactly the kind of content a scripts/ or references/ file could hold out of the main flow, so structure is good but not optimal — matching 'good structure; most content is appropriately placed; minor organization gaps' rather than the ideal split.

Specificity

The description ("Use only when the user explicitly invokes /roborev-review-branch") states a concrete trigger condition but names no capability of the skill — what "roborev-review-branch" actually does (request a code review of branch commits) is entirely absent. It is not score 1 because the language is precise rather than abstract fluff, but it cannot reach 3 because no concrete action is described.

Completeness

Only the 'when' is present ("Use only when the user explicitly invokes...") with no 'what' — the description never says the skill requests a code review for commits on the current branch. This matches the anchor 'only when is present without what' exactly; it is not 1 because the 'when' clause is explicit and unambiguous, and not 3 because the 'what' is missing rather than weakly implied.

Trigger Term Quality

The single trigger term "/roborev-review-branch" is the exact literal command a user would type for explicit invocation, which is the right trigger for this guard-style skill. However, no natural synonyms or supporting keywords are present ("code review", "review this branch", "review commits"), matching the anchor for 'some relevant keywords but missing common variations'.

Distinctiveness Conflict Risk

By restricting invocation to the literal command "/roborev-review-branch", the description has minimal conflict risk — it cannot fire on generic review requests that should use native behavior or sibling skills. The exact-command trigger is the clearest possible niche delimiter, matching the 'clear niche with distinct triggers; minimal conflict risk' anchor.
