Quality

Content

77%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is highly actionable with clear, validated workflows and feedback loops, but it is verbose due to repeated prerequisite messaging and inlines material that would benefit from being split into reference files.

Suggestions

Consolidate the bucket-existence prerequisite into one section and reference it from the others instead of restating it in the checklist, common-mistakes, and upload rules.

Move the detailed PG/NoSQL API comparison tables and RLS SQL templates into a references/ file (e.g. references/storage-pg.md) and link to it, improving progressive disclosure.

Dedupe the security-domain guidance between the 'Local dev recipe' and 'Security-domain reminder' sections.

DimensionReasoningScore

Conciseness

The body is operationally dense and valuable, but the bucket-existence prerequisite is restated across 4+ sections and security-domain guidance is repeated, so it could be meaningfully tightened.

3 / 5

Actionability

Provides copy-paste executable code for initialization, upload, progress, temp URLs, delete, download, error handling, and RLS SQL, plus concrete MCP tool calls covering the common cases.

5 / 5

Workflow Clarity

The Local dev recipe and bucket-prerequisite sections give numbered sequences with explicit validation and feedback loops (e.g. stop and fix storage on STORAGE_NOT_EXIST before retrying), matching the top anchor.

5 / 5

Progressive Disclosure

Headers and external/sibling-skill links are clearly signaled, but with no bundle files the large inline API tables and SQL templates that belong in separate reference files keep it mid-range.

Description

66%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific and identifies a clear niche with good natural keywords, but it omits an explicit 'Use when...' trigger clause, capping its completeness. Adding concrete trigger phrases would raise the score.

Suggestions

Add an explicit 'Use when...' clause naming trigger phrases, e.g. 'Use when a browser app must upload, download, or manage CloudBase storage objects via the Web SDK.'

Include natural synonyms/file extensions users say (e.g. 'file upload', 'get download URL', 'CloudBase storage bucket') to broaden trigger coverage.

Briefly distinguish the scope from sibling skills (e.g. 'browser-side only — not Mini Program or backend MCP storage') to reduce overlap risk.

DimensionReasoningScore

Specificity

Lists several concrete actions ('upload, download, temporary URLs, file management') naming the domain clearly, though 'file management' and 'best practices' are slightly generic, so it sits just below fully comprehensive.

4 / 5

Completeness

The description clearly states what the skill does but provides no 'Use when...' trigger clause, which caps completeness at 3 per the judging guidelines.

3 / 5

Trigger Term Quality

Natural keywords like 'cloud storage', 'upload', 'download', and 'temporary URLs' are present and would be said by users, but synonym coverage is incomplete and '@cloudbase/js-sdk' is technical jargon.

4 / 5

Distinctiveness Conflict Risk

It targets a clear niche (CloudBase Web SDK browser storage), but the description does not explicitly exclude overlapping sibling skills (backend MCP storage, Mini Program), keeping it just below minimal-conflict.
