88%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a well-sequenced, highly actionable instruction skill with explicit verification and honest failure paths, held back only by minor redundancy and a monolithic single-file layout that inlines a large output template and a skill-relationship section. No bundle files exist, so all content lives in SKILL.md, which is acceptable but leaves small organization gains unclaimed.
Suggestions
State the default target file (DERIVATION_PACKAGE.md in project root) once — in the Constants section or Step 1 — and drop the repetitions in Step 7 to tighten conciseness.
Consolidate the Key Rules section with the Step 7 writing rules, since several rules ('mark approximations explicitly', honesty about gaps) are stated twice.
Consider moving the full 'Required File Structure' template into a references/ file linked from Step 7 to reduce inline length and improve progressive disclosure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly lean imperative lists with no explanation of concepts Claude already knows, but the default target file rule is stated three times (Constants, Step 1, Step 7) and Key Rules partially restates earlier writing rules, so minor trimming is possible. | 4 / 5 |
Actionability | For an instruction-only skill the guidance is fully executable: a fixed status enum, an 8-step procedure with explicit sub-actions, a copy-paste-ready output file template, defined output modes, and a specified chat response format. | 5 / 5 |
Workflow Clarity | Steps 1-8 are clearly sequenced and Step 8 is an explicit verification checklist (stable invariant object, labeled steps, stated boundaries) with a feedback loop: downgrade to a blocker report instead of forcing a clean story. | 5 / 5 |
Progressive Disclosure | Well-organized single-file skill with clear section headers; its one external reference (../lean-formalize/SKILL.md) is one level deep and clearly signaled. At ~280 lines with the full output template and the proof-writer relationship section inlined, some content could arguably be split out, so organization is good but not optimal. | 4 / 5 |
