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 strong, validated workflows and executable examples, but it is verbose from heavy repetition of the bucket/PG guidance and monolithic for a skill of this length. Deduplicating and splitting the detailed PG/RLS material into a reference file would notably improve it.

Suggestions

Consolidate the repeated bucket-existence and PG-mode guidance into one authoritative section and reference it elsewhere instead of restating it 4+ times.

Extract the detailed PG-mode migration, Supabase parity table, and RLS SQL into a single reference file (e.g. references/pg-mode.md) and link to it from SKILL.md to improve progressive disclosure.

Trim explanatory prose like 'Just like Supabase Storage, CloudBase Storage requires the target bucket to exist' where the surrounding steps already make the point.

DimensionReasoningScore

Conciseness

The body is mostly efficient and the gotchas are genuinely CloudBase-specific, but the bucket-existence/PG-mode guidance is restated in 4+ places (gotchas, minimal checklist, local dev recipe, dedicated prerequisite section, PG section, upload rules) and the Supabase analogy appears twice, so it could be tightened noticeably.

3 / 5

Actionability

Provides copy-paste-ready executable code for init, uploadFile, getTempFileURL, deleteFile, downloadFile, progress, and a full RLS SQL block, with concrete MCP tool JSON invocations covering the common cases.

5 / 5

Workflow Clarity

Sequences multi-step processes with explicit validation checkpoints and feedback loops: the 6-step local dev recipe gates upload behind domain whitelisting, the bucket-prerequisite flow says to stop and fix the environment on STORAGE_NOT_EXIST, and delete instructs per-file result inspection.

5 / 5

Progressive Disclosure

Section headers are clear and sibling-skill links are well signaled, but no bundle files exist and the ~300-line body inlines material (PG-mode migration, RLS SQL, Supabase comparison) that would navigate better as one-level-deep reference files.

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 well-scoped to CloudBase Web SDK storage with good trigger terms, but it omits any explicit 'Use when' trigger guidance, which caps its completeness. Adding a trigger clause and disambiguating from sibling CloudBase storage skills would raise it.

Suggestions

Append an explicit 'when' clause, e.g. 'Use when a browser/Web app must upload, download, or manage CloudBase storage objects via @cloudbase/js-sdk.'

Add a disambiguation cue to separate this from Mini Program storage and backend/MCP storage (e.g. 'browser-side only; not for Mini Program or MCP backend management').

Swap the generic 'file management' for concrete verbs like 'delete files' and 'generate temporary URLs' to lift specificity toward 5.

DimensionReasoningScore

Specificity

Quotes 'upload, download, temporary URLs, file management, and best practices' name several concrete actions on a named domain, but 'file management' and 'best practices' are somewhat generic and delete is absent, leaving minor coverage gaps rather than comprehensive listing.

4 / 5

Completeness

It clearly states the 'what' ('Complete guide for CloudBase cloud storage using Web SDK - upload, download, temporary URLs, file management'), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which per the rubric caps completeness at 3.

3 / 5

Trigger Term Quality

Includes natural terms a user would say ('upload', 'download', 'cloud storage') plus the product-specific '@cloudbase/js-sdk', but misses common synonyms and bare file-type triggers, so coverage is good rather than comprehensive.

4 / 5

Distinctiveness Conflict Risk

The 'Web SDK (@cloudbase/js-sdk)' scoping carves a clear niche with minimal conflict risk, though the description does not disambiguate from the closely related Mini Program storage or backend/MCP storage skills, leaving minor overlap risk.
