73%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 strong, highly executable skill: complete Server Action code with auth/ownership checks, a full undo path, a clear event-timeline explanation, and an unusually thorough verification checklist. Its weaknesses are moderate redundancy between the pitfalls section and inline code comments, inlined Supabase boilerplate, and a fully single-file layout with no reference split.
Suggestions
Trim the "Common pitfalls" bullets that restate the inline code comments (effectiveFrom default, revalidatePath, slim DTO) — the table and numbered comments already carry that guidance.
Move the Supabase helper implementations to a reference file (e.g., references/supabase-helpers.md), keeping a one-line pointer in SKILL.md since they match the Paddle starter kit and are likely already present in the user's project.
Make `undoCancelSubscription` fully self-contained (inline the auth and ownership checks) or at least reference a named shared helper, so the second action is copy-paste ready like the first.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient and rich in domain knowledge Claude doesn't have (effectiveFrom semantics, the 30-minute lock, the webhook event timeline, paused-subscription 400 behavior), but noticeably tighten-able: the "Common pitfalls" bullets re-explain what the inline code comments already state ("Defaulting to `effectiveFrom: 'immediately'`", "Missing `revalidatePath`", "Returning the raw `Subscription`"), and ~45 lines of Supabase helper boilerplate are fully inlined. Matches the 'mostly efficient but includes some unnecessary explanation or could be tightened' anchor rather than the minor-trim score of 4. | 3 / 5 |
Actionability | The full `cancelSubscription` Server Action is complete, executable code with imports, an error-code map, and a slim DTO; verification steps state expected outputs ("Return `{ success: true, status: 'active', scheduledChange: '<some date>' }`"). Minor gaps keep it from a 5: `undoCancelSubscription` elides steps ("1–2. Run the same auth and ownership checks as cancelSubscription") rather than including them, and `getPaddleInstance` is imported but never defined here. Well above the pseudocode level of a 3. | 4 / 5 |
Workflow Clarity | The action is sequenced with explicit numbered steps ("1. Authenticate. Reject anonymous requests..." through "6. Turn Paddle API errors into a message the UI can show; rethrow anything else"), error recovery is built in via `CANCEL_ERRORS` mapping plus rethrow of non-ApiError failures, and "Verify the integration" is a 7-step checklist including negative tests ("Try the action while logged out (or with a forged `subscriptionId`)") and expected webhook outcomes. Validation checkpoints are explicit and comprehensive, fitting the score-5 anchor; the destructive-operation cap does not apply since undo and verification are provided. | 5 / 5 |
Progressive Disclosure | No bundle files exist (references/, scripts/, assets/ are absent), and the ~250-line body is a single well-sectioned file with clear headers and well-signaled external links (sibling skills, Paddle docs, the starter-kit reference implementation). Structure and navigation are good — matching 'good structure; most content is appropriately placed; references mostly clear' — but the score-5 'content appropriately split' anchor isn't met: nothing is split out, and material like the Supabase helpers or pitfalls could live in a reference file. | 4 / 5 |
