85%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.
This is a strong, highly actionable skill body: executable code, explicit decision tables, and an unusually thorough verification checklist. Its weaknesses are the inlined Supabase boilerplate and the monolithic single-file structure, which keep conciseness and progressive_disclosure below the top anchors.
Suggestions
Move the @supabase/ssr helper code (src/utils/supabase/server.ts and server-internal.ts) into a references/ file and keep only a one-line pointer in SKILL.md — it is standard boilerplate peripheral to the plan-change task.
Split the deep-dive material (e.g. the onPaymentFailure variants, same-interval addon rules, and the webhook side-effects sequence) into a reference file, keeping SKILL.md as a decision-focused overview.
Trim redundant restatements across sections — e.g. the trialing/do_not_bill rule and the 'credit, never a card refund' point each appear three or more times.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly efficient and dense with genuinely non-obvious Paddle knowledge (proration mode constraints, status rules, error codes), but the ~45-line "Supabase helpers" section inlines standard @supabase/ssr boilerplate Claude already knows. This fits 'Efficient; minor instances of over-explanation that could be trimmed' rather than level 5's 'every token earns its place'. | 4 / 5 |
Actionability | The skill provides a fully executable copy-paste-ready Server Action, a previewUpdate snippet with explained response fields, an admin-driven variant, env-var setup, and an error-code-to-message map. It matches 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'. | 5 / 5 |
Workflow Clarity | The flow is clearly sequenced (choose prorationBillingMode → check subscription status → preview → commit) with an explicit 9-step 'Verify the integration' checklist covering failure paths (declining test card, forged subscriptionId, trialing, renewal lock, rate-limit retry). This matches 'Clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes'. | 5 / 5 |
Progressive Disclosure | The single 337-line SKILL.md has no bundle files at all; auxiliary content — the Supabase helper boilerplate, the full onPaymentFailure variants, and the webhook side-effects — is inlined rather than split into reference files. It fits 'Some structure but could be better organized; content that should be separate is inline', not level 4, which expects most content appropriately placed across files. | 3 / 5 |
