78%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-architected skill body: it teaches one unifying four-primitive pattern, routes cleanly to three substantive per-gateway references, and includes concrete anti-patterns and a real CI snippet. Main improvement room is redundancy in companion-skill pointers and the absence of a single worked test example showing the shared pattern in code.
Suggestions
Consolidate the five mentions of payment-flow-test-author (steps 4-5, the anti-patterns table, and two References bullets) into one clearly worded pointer to avoid repeating the near-identical '(its payment-states reference)' phrasing.
Add one minimal executable test example in the body (e.g., a test driving an Adyen 'Refused' card and asserting the result code) to demonstrate the shared pattern end-to-end before delegating to references.
In the shared pattern, name the concrete command/API for firing each gateway's webhook simulator (or link the exact reference section) so step 3-4 verification is directly executable rather than only described.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Largely lean: compact tables, a tight CI YAML snippet, and no explanation of concepts Claude already knows (the Overview's four-primitive model is load-bearing framing, not padding). Not a 5 because the companion skill `payment-flow-test-author` is pointed to five times, twice with near-duplicate "(its payment-states reference)" phrasing (lines 56-58, 86, 108-110) — minor trimming is clearly available. | 4 / 5 |
Actionability | Mostly executable: a copy-paste GitHub Actions snippet with real secret names (ADYEN_TEST_API_KEY, PAYPAL_SANDBOX_CLIENT_ID, BT_SANDBOX_MERCHANT_ID), concrete signature schemes ("HMAC-SHA256 for Adyen, SHA256-with-RSA for PayPal, `bt_signature` parsing for Braintree"), and a fixes column in the anti-patterns table. Not a 5 because the core common case — an example test driving a documented outcome row — has no code sample in the body; the pattern is precisely described but never shown. | 4 / 5 |
Workflow Clarity | The "shared sandbox test pattern" is a clear 5-step sequence with validation requirements embedded as assertions ("asserting the gateway's own result-code vocabulary", "the suite must reject unsigned and wrong-secret payloads", "process-exactly-once is the contract"). Not a 5 because there are no feedback/recovery checkpoints and concrete per-step mechanics (e.g., firing the webhook simulator) are deferred to references, leaving minor gaps against the explicit-validation anchor. | 4 / 5 |
Progressive Disclosure | Exemplary structure: the body is a genuine overview (shared pattern, routing table, anti-patterns, limitations), and all per-gateway detail is one level deep in real, substantive files — references/adyen.md, references/paypal.md, references/braintree.md each verified to exist with executable content. The routing table labels each reference with a distinctive trait and the References section re-signals every path, making navigation trivial. No nesting beyond one level. | 5 / 5 |
