82%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-engineered router skill: executable code sketches, concrete security rules with real examples, and crisp decision tables for sub-skill routing. The main costs are minor redundancy and deep generation-persistence/credential detail inlined at overview level rather than left to the sub-skills it already routes to.
Suggestions
Merge or deduplicate the two `log` bullets in the Secure persistence section — they overlap and both constrain the same input lane.
Move the byte-storage detail (storageKey callback, blobKey backfill, fetch caps, snapshot transactions) into the build-*-adapter / artifact-store sub-skills and keep only the routing pointer plus the one-line authorization rule at overview level.
Add a short feedback-loop note under the conformance testkit rule (e.g., 'fix the failing contract and re-run until green before shipping the adapter') to complete the validation cycle.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense with library-specific rules Claude could not know ("Default blob key is `artifacts/<runId>/<artifactId>`", "404, not 403, so valid ids aren't confirmed") and never explains known concepts — SSRF, path traversal, and envelope encryption are used as shorthand, not taught. It misses the 5 anchor on small redundancy: the two overlapping `log` bullets in Secure persistence, and "A replayable stream is not a saved conversation. A saved conversation is not a live stream." restating the layer table. | 4 / 5 |
Actionability | The minimal end-to-end sketch is complete, executable code for both server route and client hook, and guidance comes with concrete values throughout: a worked `storageKey` callback payload, a real predicate example (`allowInputUrl: ({ url }) => url.hostname.endsWith('.cdn.example.com')`), and decision tables that route to a specific adapter recipe per stack. No pseudocode filler. | 5 / 5 |
Workflow Clarity | "Recommended production stack" gives a numbered 1–4 sequence, "Run the conformance testkit against any adapter you write" is an explicit validation checkpoint, and the routing tables make the navigate-to-sub-skill workflow unambiguous. Not 5: there is no inline feedback loop (e.g., what to do when the testkit fails) and the implementation order across sub-skills is implied rather than sequenced. | 4 / 5 |
Progressive Disclosure | No bundle files exist under this skill (no references/, scripts/, or assets/), and all pointers go one level deep to sibling skill files, clearly signaled via "Need to... / Read" and "The app runs... / Read" routing tables — good navigation. Not 5: substantial deep material (byte-storage security, CredentialStore rules, sandbox snapshot transactions) is inlined in this overview where sub-skills likely repeat it. | 4 / 5 |
