Conciseness

The body is mostly efficient — no concept explanations, no library tours — but several bullets restate standard review judgment Claude already applies ("Is the code easy to understand at a glance?", "Are functions/classes/modules small, cohesive, and well-factored?") and the Risk & Impact section overlaps the Maintainability section. This fits anchor 3 (could be tightened) rather than anchor 4 (only minor trims) or anchor 2 (no padded sections or unnecessary explanations).

Actionability

Guidance is mostly executable for an instruction-only skill: concrete deliverables ("structured review", "specific, actionable improvements", a ready-to-commit verdict) and exact commands ("tuicr -w", "tuicr review list --repo .", "tuicr review comments --session <slug> --repo ."). Minor gaps — no command for obtaining the pending diff and no pointer to where project rules live (e.g., CLAUDE.md) — keep it at anchor 4 rather than 5.

Workflow Clarity

As a simple single-purpose skill the flow is coherent: evaluation criteria grouped into four labeled areas, then explicit deliverables, with the conditional tuicr path clearly subordinated ("the TUI and its saved comments do not replace that work"). It sits at anchor 4 rather than 5 because the sequence from "pending, uncommitted changes" to output (inspect diff → evaluate → report) is implicit, with no explicit starting step. No destructive or batch operations are involved, so the validation cap does not apply.

Progressive Disclosure

The body is under 50 lines, needs no external references, and is organized into clearly labeled sections (Task, Deliverables, Optional interactive review) with no inlined content that belongs in separate files. Per the rubric's simple-skill guideline this earns anchor 5.

Specificity

The description names the domain and one concrete action — "Review pending changes for tests, maintainability, and project rules" — but relies on a single verb with three focus areas rather than listing several distinct actions, matching anchor 3. It is not anchor 4 because anchor-4 examples enumerate multiple specific actions (e.g., extracts, fills, converts), while this offers one review action.

Completeness

Both parts are explicit: the what ("Review pending changes for tests, maintainability, and project rules") and a concrete when-clause listing multiple trigger phrases. This matches anchor 5's requirement to clearly and explicitly answer both what AND when; anchor 4 applies when the when-clause could be more explicit, which is not the case here.

Trigger Term Quality

"Use when the user asks for code review, review pending changes, or alignment with maintainability and project rules" includes the natural phrases users would say ("code review", "review pending changes"), giving good keyword coverage. It falls short of anchor 5 because common synonyms like "diff", "uncommitted changes", or "pre-commit review" are missing.

Distinctiveness Conflict Risk

The XP framing (tests, maintainability, project rules, pending changes) carves out a mostly distinct niche with minor overlap risk against a general code-review skill. It is not anchor 5 because "code review" is a broad trigger that a generic review skill would also claim; it is clearly more specific than anchor 3's "Works with document files".
