skill-creator

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

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 body is a well-structured, actionable meta-skill with clear sequencing, an explicit validation feedback loop, and clean progressive disclosure via real one-level-deep references. The main drag is conciseness — a few metaphors and some restated content could be trimmed to better honor its own 'concise is key' principle.

Suggestions

Trim the degrees-of-freedom metaphor ('narrow bridge with cliffs' / 'open field') and the 'onboarding guides' framing to reduce token cost without losing the point.

Dedupe the anatomy: the directory tree and the per-resource subsections both define scripts/references/assets; consolidate so each resource type is described once.

Add the concrete resource categories (scripts, references, assets) to the frontmatter description so the description matches the body's emphasis and improves trigger breadth.

Dimension	Reasoning	Score
Conciseness	Mostly efficient and well-structured, but includes more than minor over-explanation: an extended degrees-of-freedom metaphor ('narrow bridge with cliffs', 'open field'), restated concepts between the anatomy tree and the resource subsections, and framing like 'Think of them as onboarding guides'.	3 / 5
Actionability	Provides concrete executable commands (init_skill.py, package_skill.py invocations) and a real example description, but the bulk of the skill is instructional guidance for writing rather than copy-paste code; appropriate for an instruction-heavy skill with minor gaps.	4 / 5
Workflow Clarity	A clearly ordered 6-step process with an explicit validate→fix→re-run feedback loop in packaging ('If validation fails... Fix any validation errors and run the packaging command again') and a 'test scripts by actually running them' checkpoint in editing.	5 / 5
Progressive Disclosure	Body is ~350 lines (under its own 500-line guideline), with real, verified, one-level-deep references (references/workflows.md, references/output-patterns.md) that are clearly signaled and described with when-to-read guidance; content is appropriately split.	5 / 5

Description

87%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 cleanly answers both 'what' and 'when' with concrete, natural trigger phrases and a distinct niche. Its main weakness is trigger/specificity breadth: it omits synonyms and the concrete resource categories (scripts, references, assets) the body emphasizes.

Dimension	Reasoning	Score
Specificity	Names the domain ('creating effective skills') and several concrete actions — 'create a new skill (or update an existing skill)' and 'extends Claude's capabilities with specialized knowledge, workflows, or tool integrations' — but does not enumerate resource types (scripts/references/assets), leaving minor coverage gaps.	4 / 5
Completeness	Explicitly answers both what ('Guide for creating effective skills... extends Claude's capabilities with specialized knowledge, workflows, or tool integrations') and when ('This skill should be used when users want to create a new skill (or update an existing skill)') with concrete trigger phrasing.	5 / 5
Trigger Term Quality	Includes genuinely natural trigger phrases ('create a new skill', 'update an existing skill') that users would say, but lacks synonyms ('build/make a skill') and file extensions (.skill).	4 / 5
Distinctiveness Conflict Risk	Skill-creation is a clear meta-niche with distinct triggers and minimal overlap risk against other skills.	5 / 5
