77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, highly actionable skill that covers a complex billing integration thoroughly — proration modes, replace semantics, preview-before-commit, payment failure handling, and security checks are all well-addressed with executable code. Its main weakness is verbosity: some sections repeat earlier guidance, and the monolithic structure could benefit from splitting detailed reference material (proration table, pitfalls) into separate files. The verification checklist is excellent and covers edge cases most skills miss.
Suggestions
Trim the 'Common pitfalls' section by removing items that directly restate guidance already given in earlier sections (e.g., proration mode selection, replace-not-append, ownership check) — or consolidate them into a compact checklist.
Consider extracting the proration mode tables and payment failure details into a referenced file (e.g., PRORATION.md) to keep the main skill focused on the action implementation and reduce inline length.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is thorough and mostly earns its length given the complexity of proration modes and edge cases, but several sections are verbose — e.g., the 'When to use this skill' intro paragraph, the lengthy 'Common pitfalls' section repeats guidance already covered in earlier sections, and some explanations (like what happens on payment failure) could be tightened. The tables are efficient, but surrounding prose could be leaner. | 2 / 3 |
Actionability | The skill provides a complete, copy-paste-ready Server Action with real imports and Supabase integration, executable preview code, explicit SDK parameter names (camelCase vs wire format noted), and concrete examples of both the default and admin-driven update calls. The code is production-shaped, not pseudocode. | 3 / 3 |
Workflow Clarity | The skill clearly sequences the workflow: auth → ownership check → (optional) preview → update → revalidate → return slim DTO. The 'Verify the integration' section provides an 8-step validation checklist covering happy path, payment failure, invalid inputs, and auth bypass. Feedback loops are explicit (preview before commit, retry on decline, validate newPriceId). | 3 / 3 |
Progressive Disclosure | The skill references related skills (subscription-sync, subscription-cancel) and links to external Paddle docs, which is good. However, with no bundle files, all content is inline in a single long document (~250+ lines). The proration tables, pitfalls list, and verification steps could benefit from being split into referenced files, and the document lacks a quick-start summary at the top that points to detailed sections. | 2 / 3 |
