Quality

Content

82%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.

A well-engineered overview: lean, information-dense, actionable where it counts, with a clean one-level-deep reference structure. Minor gaps — a few sections lack inline code, no explicit error-recovery loop, and a redundant final reference list — keep it just short of top marks.

DimensionReasoningScore

Conciseness

The body is dense throughout — capability tables, exact limits ('decoded request/response bodies limited to 8 MiB'), and imperative guidance with no padding and no explanations of concepts Claude already knows. Nothing could be trimmed without losing information.

5 / 5

Actionability

Copy-paste scaffold commands, a complete executable src/plugin.ts example, and named test-host functions give concrete guidance, but routes/MCP tools and admin UI sections have no inline code examples (they defer to references), leaving minor gaps.

4 / 5

Workflow Clarity

Sections sequence the build flow (choose format → scaffold → declare access → routes/hooks/UI → runner parity → test) with a dedicated validation section naming two specific test hosts and disposal requirements, but there is no explicit validate→fix→retry feedback loop.

4 / 5

Progressive Disclosure

Each of the 12 reference files (all verified to exist) is signaled at its point of use and references are one level deep with only peer cross-links, but the trailing References section duplicates the inline links and publishing.md appears only there without a contextual pointer.

Description

92%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.

A strong description: third-person voice, comprehensive and concrete capability listing, and an explicit use-when trigger clause. The only weakness is slightly limited synonym coverage for trigger terms.

DimensionReasoningScore

Specificity

The description enumerates the full capability surface — 'sandboxed hooks, routes, storage, content and media APIs, MCP tools, and declarative admin UI, or native React and Astro extensions' — matching the comprehensive multi-action coverage of the top anchor.

5 / 5

Completeness

Sentence one explicitly states what the skill does and sentence two gives an explicit 'Use when scaffolding or implementing an EmDash plugin' trigger clause with concrete trigger phrases.

5 / 5

Trigger Term Quality

'scaffolding or implementing an EmDash plugin' and 'extensions' are natural phrases users would say, but synonym coverage is limited to plugin/extension with no adjacent terms (e.g. plugin CLI, registry, Block Kit) a user might mention.

4 / 5

Distinctiveness Conflict Risk

The 'EmDash CMS plugins' niche is highly specific with distinct triggers, so conflict with other skills is minimal.
