skill-creator

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Quality

Content

75%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 well-structured, actionable guide that assumes Claude's competence and leverages real bundle files. It scores consistently high across dimensions with only minor tightening and checkpoint improvements possible.

Suggestions

Add an explicit validate-and-retry loop for the eval-run step (run evals -> inspect failures -> revise) to strengthen workflow_clarity checkpoints.

Tighten prose like 'Keep the body focused on workflow, decisions, and output expectations' into a direct directive to nudge conciseness toward 5.

Link the body's references to the specific bundle files (e.g., scripts/run_eval.py, references/schemas.md) by name so progressive disclosure navigation is fully explicit.

DimensionReasoningScore

Conciseness

Mostly lean and imperative with a concrete template, but includes a few explanatory sentences ('Keep the body focused on workflow...') that could be trimmed.

4 / 5

Actionability

Provides a concrete copy-paste YAML template and a JSON sync snippet with real paths; minor gaps in full executable coverage of the test/eval workflow.

4 / 5

Workflow Clarity

Clear create -> draft -> test -> improve sequence with a completion checklist acting as validation; minor checkpoint gaps in the eval-run step.

4 / 5

Progressive Disclosure

Well-organized sections that point to real scripts/ and references/ bundles (schemas.md confirmed present); mostly clear one-level-deep navigation with minor organization gaps.

Description

88%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 well-constructed description that concretely states capabilities and provides explicit trigger guidance with natural user phrasing. It is comprehensive and specific without being padded.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('Create new skills, modify and improve existing skills, and measure skill performance') with comprehensive coverage of the skill's capabilities.

5 / 5

Completeness

Clearly answers both what the skill does and an explicit 'Use when users want to...' clause with concrete trigger phrases.

5 / 5

Trigger Term Quality

Strong natural terms ('create a skill from scratch', 'edit', 'optimize', 'run evals', 'benchmark') but a few synonyms or phrasings a user might say are missing.

4 / 5

Distinctiveness Conflict Risk

Clear meta-skill niche with distinct triggers; minor overlap risk with general coding or optimization skills.
