The body is a highly actionable, executable reference with lean code-first sections, but it stumbles on workflow safety and structure: destructive/batch operations (multi-file remove, bucket creation, RLS policies) have no validation or feedback loops, and its progressive disclosure is undermined by a broken reference link and policy content inlined that duplicates the existing reference file.
Suggestions
Add validation checkpoints around destructive/batch operations: before `remove([...])` list files to confirm targets, check the returned error, and verify deletion afterward; similarly show verifying a bucket exists before INSERT and checking policy application with a test query.
Fix the References section: either create references/upload-patterns.md or remove the link, since the file is missing from the bundle.
Move the full 'Storage RLS Policies' SQL examples into the existing references/storage-policies.md and keep only one or two exemplar policies inline, trimming the near-duplicate 'Download as Blob'/'Download to Browser' pair to one section.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is almost entirely lean, executable snippets with one-line annotations ("upsert: true // Replace if exists", "// data is a Blob") and no padding explaining concepts Claude already knows, matching the 'efficient; minor instances that could be trimmed' anchor — e.g., 'Download as Blob' and 'Download to Browser' largely repeat each other, and the 'Enable RLS' section is only an empty SQL comment. | 4 / 5 |
Actionability | Every section provides copy-paste-ready executable JavaScript/SQL/TOML covering the common cases — uploads (basic, options, browser, base64), downloads, public/signed URLs, list with search, single/multiple delete, move/copy, transforms, RLS policies, plus concrete error-message branching ("The resource already exists", 'exceeded', 'mime type') — matching the 'fully executable; covers common cases' anchor. | 5 / 5 |
Workflow Clarity | The skill is reference-style with clearly organized task sections, but the destructive and batch operations lack validation or verification checkpoints: `remove([...])` deletes multiple files with no pre-check or post-verification, bucket creation and RLS policies apply with no confirm/rollback guidance, and error handling is shown only for uploads. Per the rubric cap, destructive/batch operations without validation cannot score above 3; the missing checkpoints for delete/policy operations keep it at the 'sequence present but checkpoints missing' anchor. | 3 / 5 |
Progressive Disclosure | Section structure is clear and the References section signals one-level-deep files, but one of the two referenced files (references/upload-patterns.md) does not exist in the bundle, breaking navigation, and ~60 lines of RLS policy SQL are inlined in the body that duplicate content in the existing references/storage-policies.md — content that belongs in the separate file sits inline and a listed reference is dead, matching the 'could be better organized; references present but not clearly signaled' anchor. | 3 / 5 |
