Quality

Content

100%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 body is a tight, executable, well-sequenced workflow with explicit validation and verification checkpoints and no padding or concept over-explanation. It is an exemplar of an instruction-only skill that earns full marks without external bundle files.

Dimension	Reasoning	Score
Conciseness	Lean and efficient throughout — it never explains what a plugin, manifest, or MCP server is, and every line (paths, the TOML block, the trust/enable steps) is load-bearing guidance Claude does not already know.	5 / 5
Actionability	Fully executable guidance: concrete bundle paths, a complete copy-paste-ready plugin.toml, exact commands (`/plugin validate`, `/plugin show`, `/plugin enable`, `/plugin trust`), and a precise `${SOURCE_ENV}` syntax rule for environment mapping.	5 / 5
Workflow Clarity	An 8-step sequence with explicit validation checkpoints (step 7 validate/show/enable/trust, step 8 verify `/skills inspect` and `/plugin list` state) and a feedback loop (run the exact trust confirmation, then enable again), matching the anchor for clear sequencing with error-recovery loops.	5 / 5
Progressive Disclosure	A single self-contained file (no references/ scripts/ assets/ bundle present) organized into a clear overview plus a numbered Workflow section; content is appropriately scoped and easy to navigate with no nested references.	5 / 5

Description

75%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, action-oriented, and clearly niche-scoped, but it omits any explicit "Use when..." trigger guidance, which caps its completeness. Adding a concrete trigger clause would lift the weakest dimension.

Suggestions

Append an explicit trigger clause such as "Use when a user wants to create, scaffold, or package a local Codewhale plugin bundle".

Add a few natural synonyms or surface terms a user might say (e.g., "plugin package", "plugin skeleton", "Codewhale extension") to broaden trigger coverage.

Keep the concise action list as-is; it is the strongest part of the description.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions — "Scaffold", "versioned manifest", "namespaced Skills", and "explicit trust review" — giving comprehensive coverage of the skill's capabilities within its domain.	5 / 5
Completeness	The "what" is clear, but there is no "Use when..." clause or equivalent explicit trigger guidance; per the rubric a missing 'Use when...' caps completeness at 3.	3 / 5
Trigger Term Quality	Natural terms like "plugin bundle", "manifest", "Skills", and "trust review" are present and on-point, but it lacks synonyms or the kind of varied phrasings a user might spontaneously say, so it falls just short of comprehensive coverage.	4 / 5
Distinctiveness Conflict Risk	Targets a clear niche (local Codewhale plugin bundles) with distinct, specific triggers, so the risk of firing for an unrelated skill is minimal.	5 / 5
