81%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.
A well-crafted instruction-only skill: the red-green-red loop is precisely sequenced with explicit validation and feedback loops, the guidance is concrete with real commands and worked examples, and nothing pads the token budget. Remaining gaps are minor — some redundancy between the 'Workflow' and 'The loop' sections and placeholder commands in the revert snippet.
Suggestions
Merge the 'Workflow' section into 'The loop' — both describe the same evidence-preserving sequence, and stating it once would trim ~10 lines without losing information (conciseness).
Make the step-4 revert snippet more copy-paste ready by showing one concrete instantiation (e.g., a real test-runner command alongside the placeholder) so the pattern is executable as-is on a first read (actionability).
Consider moving the two extended real-world failure examples into a short references/ file, keeping only their one-line morals in SKILL.md, if the skill grows further (progressive_disclosure).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense with non-obvious, earned guidance (the revert trap, two real failure examples, the fallback-test-type table) and explains nothing Claude already knows. Minor trimming is possible — the 'Workflow' section (lines 19–27) substantially restates 'The loop', and the attribution/license footer is boilerplate — placing it at anchor 4 ('efficient; minor instances… that could be trimmed') rather than the fully lean anchor 5 or the noticeably padded anchor 3. | 4 / 5 |
Actionability | Concrete, near-executable guidance throughout: 'git log -S \'<the exact line>\'', a copy-paste bash backup/revert/restore block, a test-naming convention with a good/bad example, and a decision table for unreachable code paths. The central bash block still contains placeholder commands ('<run the specific test>'), so it is 'mostly executable… with minor gaps' (anchor 4) rather than fully copy-paste ready (anchor 5); for an instruction-only methodology skill with no fixed codebase the placeholders are justified. | 4 / 5 |
Workflow Clarity | A numbered 5-step loop with explicit ordering rules ('Do not skip 1, and never skip 4'), validation checkpoints at every phase, feedback loops ('If it does not fail, you have not reproduced the bug. Go back to step 1'; the step-4 revert-red check that labels a stayed-green test 'fake'), a recovery path for each failure mode, and a final full-suite check with instructions for contradicting tests. This matches anchor 5: clear sequence, explicit validation, feedback loops, and checklists. | 5 / 5 |
Progressive Disclosure | No bundle files exist and none are referenced; the single file (~159 lines) is organized into clearly headed sections (Overview, The loop, target picking, fallback table, Reporting, Anti-patterns). This is good structure with content appropriately placed (anchor 4), but the under-50-line simple-skill exception for a 5 does not apply, and the extended examples and fallback table could conceivably live in reference files if the skill grew. | 4 / 5 |
