A lean, opinionated review checklist that assumes Claude's competence and encodes genuinely project-specific knowledge — no padding with concepts Claude already knows. Its main gap is procedural: the review workflow (order of operations, how to verify findings against the dependency rules, how to structure the report) is left implicit.
Suggestions
Add a short sequenced workflow — e.g. start from the diff, sweep the codebase through it as a lens, then verify each finding against the one-way rule before reporting — with an explicit checkpoint step.
Include one worked example of a well-formed finding (finding text + `file:line` + the concrete fix) so the output contract is unambiguous.
Trim the opening paragraph's ambition framing, which repeats what the description already says.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and mostly earns its tokens with project-specific judgments Claude couldn't know ("home → rigging → hull; only src/ crosses decks", "rigging/lib", "zine.md", PGlite). Not 5 because the opening paragraph ("Be ambitious. This is for a crew with a high craft bar and a willingness to invest — don't self-censor") largely restates the description's "Ambitious by design — for a crew with a high craft bar" framing. | 4 / 5 |
Actionability | Concrete, executable guidance throughout: "Every finding gets `file:line` and a concrete fix", "Propose early returns, guard clauses, lookup tables, or a named function", "Hoist it to a shared top-level utility… e.g. `rigging/lib`". Not 5 because there is no worked example of a well-formed finding or split, which for an instruction-only skill is the equivalent of the copy-paste-ready example the top anchor requires. | 4 / 5 |
Workflow Clarity | The content is organized as seven parallel review lenses plus project grain, not as a sequenced process — there is no explicit order (e.g. read the diff first, sweep the codebase, then report findings) and no checkpoints or verification step (e.g. confirming each proposed refactor is consistent with the one-way rule before reporting). This matches 'structure present but sequence/checkpoints implicit or missing'; not 4, because no sequence is stated at all, and not 2, because the Scope section does give directional guidance on how to use a diff as a lens. | 3 / 5 |
Progressive Disclosure | Clean one-level structure ("## What to look for", "## Skylark's grain", "## Scope") with everything appropriately inline for a ~60-line skill and no bundle files to reference. Not 5: it sits just past the 'under 50 lines, no external references needed' case, and the two concern sets (review lenses vs. Skylark's grain) offer a natural split point if the skill grows. | 4 / 5 |
