77%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: the Server Action is complete and executable, the security model and pitfalls sections are specific and correct, and the verification checklist provides genuine feedback loops. The main weaknesses are token weight from inlined peripheral material (Supabase helpers, the trade-off essay) that would be better placed in reference files or trimmed.
Suggestions
Move the two Supabase client helper implementations into a references/ file (or trim to a note pointing at the starter-kit pattern) — they are peripheral glue code, not portal logic.
Compress the portal-vs-custom comparison table and 'Should you use the portal at all?' prose into a short decision summary with a pointer, reclaiming a large share of the body's token budget.
Extract the per-URL API detail (e.g. the view_subscription / direct-POST workaround, the 25-ID limit rules) into a compact reference table so the main body stays a lean overview.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly efficient and skill-specific, but the two full Supabase client helper implementations, the lengthy portal-vs-custom comparison table, and extended prose around known concepts (e.g. service-role/RLS behavior) could be tightened or externalized. This fits "mostly efficient but includes some unnecessary explanation or could be tightened" rather than the minor-trimmings-only bar for a 4. | 3 / 5 |
Actionability | Provides a complete, copy-paste-ready Server Action with imports, typed error handling for both ApiError and the no-customer case, a working client component, env var configuration, and Supabase helpers — covering the common cases end to end. Fully executable with no gaps. | 5 / 5 |
Workflow Clarity | The sequence (prerequisites → session semantics → full action → security model → pitfalls → verification) is clear, with an explicit 6-step "Verify the integration" checklist covering success, uniqueness-per-click, unauthenticated, no-customer, and ownership-escalation cases. Not a destructive or batch operation, so the validation cap does not apply. | 5 / 5 |
Progressive Disclosure | Sections are well-organized with clear headers and outbound links to Paddle docs, but this is a ~240-line single file with no bundle files; content that would sit better in references (Supabase helpers, the portal-vs-custom comparison, the view_subscription API detail) is inlined. Fits anchor 3 ("some structure... content that should be separate is inline"); the under-50-line simple-skill exception does not apply. | 3 / 5 |
