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, actionable skill: the full Server Action is nearly copy-paste ready, the workflow has explicit validation and a real verification checklist, and the security model is unusually well articulated. The main costs are token weight from boilerplate Supabase code and triple-stated security points, plus one undefined import (`getPaddleInstance`).
Suggestions
Define or stub `getPaddleInstance()` (the one imported helper the skill never shows) so the full action is truly copy-paste ready.
Trim the Supabase `createServerClient` boilerplate to a short note plus a link to the starter kit — Claude already knows the @supabase/ssr cookie pattern — and drop the trivial client-button component.
State the core security invariants once (Security model) and let the code comments and pitfalls reference them instead of restating "return only the URL" and "customerId from auth, not input" in all three places.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The Paddle-specific core (URL structure, the 25-subscription-ID limit, pitfalls, verification) is tight and earns its tokens — fitting anchor 3 rather than anchor 2 because most sections are lean — but the ~47 lines of boilerplate Supabase helper code, the trivial client button component, and the "return only the URL / never trust a client-supplied customerId" point stated three times (code comments, Security model, and Common pitfalls) are padding that could be trimmed. | 3 / 5 |
Actionability | "The full Server Action" is executable with imports, auth check, DB lookup, error handling, and a client component, plus prerequisites and env vars — but `getPaddleInstance` is imported from `@/utils/paddle/get-paddle-instance` and never defined anywhere in the skill, a minor gap that breaks full copy-paste readiness (anchor 5). | 4 / 5 |
Workflow Clarity | The sequence (prerequisites → Supabase helpers → how portal sessions work → full action → security model → pitfalls → verification) is clearly ordered, the action has numbered steps with an explicit error-recovery loop (ApiError → user-facing message, rethrow anything else), and "Verify the integration" is a 6-item checklist covering negative paths (logged out, no customer, cross-customer minting, URL uniqueness per click). | 5 / 5 |
Progressive Disclosure | Sections are well-organized with clear headers and external doc links are clearly signaled, but there are no bundle files at all: the long portal-vs-custom trade-off table and the Supabase helper code could live in reference files, and sibling-skill mentions (`subscription-cancel`, `subscription-update`, `subscription-sync`) are backticked prose names without paths — good structure with minor organization gaps (anchor 4). | 4 / 5 |
