71%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-structured, mostly executable guide: a compact endpoint table, a working 402→payment→retry implementation with legacy fallback, and a quick validation path. Its main weaknesses are the two references to bundle files (references/endpoints.md, references/signer-setup.md) that are not present in the skill directory, which weakens both actionability and progressive disclosure, plus small redundancy between the examples and the Quick Test section.
Suggestions
Ship the referenced bundle files — include references/endpoints.md and references/signer-setup.md in the skill directory (or inline the minimal signer configuration) so the two body references and the undefined `signer` in the client-registration example resolve.
Add a payment-failure checkpoint: note how to detect and surface insufficient-USDC errors and, after a paid call, verify the PAYMENT-RESPONSE header (payer, tx hash) before treating the result as settled.
Trim the 'Quick Test' section or fold it into the examples block to remove the duplicated /treasury-curve and /riesgo-pais calls.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean — an endpoint table instead of prose, a complete fetchBT implementation, and no explanation of concepts Claude already knows; the 'How x402 Works' explanation is justified since x402 is a niche recent protocol. It falls short of anchor 5 only through minor redundancy: the 'Quick Test' section repeats fetchBT('/treasury-curve') and fetchBT('/riesgo-pais') calls already shown as examples above, and 'How x402 Works' partially restates what the code implements. | 4 / 5 |
Actionability | Concrete install command, working client registration code, and a fully executable fetchBT function with 402 handling and legacy X-PAYMENT fallback cover the common cases. It is not anchor 5 because the signer — the one piece a user cannot run without — is deferred to 'references/signer-setup.md', which does not exist in this bundle, leaving the main example with an undefined `signer` variable (though the interface contract {address, signTypedData} and the linked external docs partially compensate). | 4 / 5 |
Workflow Clarity | Setup is explicitly sequenced (1. Install, 2. Configure signer, 3. Register client), the fetch flow has a built-in feedback loop (402 → create payment → retry → legacy fallback retry), and the 'Quick Test' validates both the free and paid routes. It stops short of anchor 5 because there is no checkpoint for payment failure modes (e.g. insufficient USDC balance) and no verification of the PAYMENT-RESPONSE settlement metadata that the Notes section itself mentions. | 4 / 5 |
Progressive Disclosure | Section structure and signaling are good (clearly labeled endpoint overview, 'Endpoint reference in this skill: references/endpoints.md', 'See references/signer-setup.md'), but both referenced files are absent from the bundle — the references directory does not exist — so navigation to the signer setup and endpoint details dead-ends. This is worse than anchor 4's 'minor organization gaps'; a dangling reference breaks discovery, matching anchor 3's 'could be better organized' despite the in-skill structure itself being sound. | 3 / 5 |
