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-structured, actionable skill body: a clear 7-step workflow with an end-to-end checklist, executable pytest patterns for each failure mode, and an appropriately used one-level-deep reference file. The main issues are cosmetic — verbatim prose duplicated between SKILL.md and the reference file, minor undefined fixtures in examples, and a messy References section.
Suggestions
De-duplicate the Step 4 and Step 6 prose against references/idempotency-patterns.md — keep a one-line summary in SKILL.md and let the reference file carry the full explanation and code.
Make the test examples self-contained: define the `charge` variable in the TTL test and briefly note that `endpoint`, `store`, and `charge_processor` are app-specific fixtures to be adapted.
Clean up the References section: move the `[aws-idem]:` link definition to the bottom of the file, use a normal markdown link instead of `[aws-idem][aws-idem]`, and keep each sibling-skill bullet on a single line.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient — tables, checklists, and test code are tight — but the Step 4 and Step 6 prose ("Some systems can't add idempotency keys...", "The hardest case: two requests with the same idempotency key arrive simultaneously") is duplicated nearly verbatim in references/idempotency-patterns.md, and the Stripe pattern recap partially re-explains what Claude already knows. Not 5: the cross-file duplication is avoidable token cost; not 3: padding is limited to a couple of spots rather than several sections. | 4 / 5 |
Actionability | Real, runnable pytest patterns with concrete assertions ("assert (status1, body1) == (status2, body2)", "assert charge_processor.execute.call_count == 1") cover every common case, and advanced code lives in the verified reference file. Not 5: examples are not fully self-contained — the TTL test uses an undefined `charge` variable and fixtures like `endpoint`/`store`/`charge_processor` are assumed without definition; not 3: this is executable code, not pseudocode. | 4 / 5 |
Workflow Clarity | Steps 1–7 form a clear sequence culminating in an explicit per-handler checklist ("1. ✅ Single-request happy path test ... 6. ✅ ... redelivery ... doesn't double-process"), with each step's test pattern carrying its own assertion-based checkpoint and the Anti-patterns table serving as error-recovery guidance. Not 4: validation checkpoints are explicit in the end-to-end recipe rather than merely present. | 5 / 5 |
Progressive Disclosure | "Full code + test: [references/idempotency-patterns.md](references/idempotency-patterns.md)" is a well-signaled, one-level-deep, verified reference at the point of use, and the core-key vs. advanced-concurrency split is appropriate. Not 5: the References section navigation is messy — the `[aws-idem]:` link definition sits mid-body (between Overview and When to use), sibling-skill bullets wrap mid-sentence, and `[aws-idem][aws-idem]` is an awkward link form; not 3: the file split and in-context signals themselves are well done. | 4 / 5 |
