eval-skills

name	eval-skills
description	Audit all skills in .claude/skills/ for frontmatter completeness, effort level appropriateness, allowed-tools scoping, and content quality. Produces a scored report with effort-level recommendations for each skill. Use when onboarding, reviewing skill quality before shipping, or adding effort fields to an existing skill library.
allowed-tools	Read, Glob, Bash
effort	medium

Skill Evaluator

Discover all skills, score them across 6 criteria, and infer the appropriate effort level based on content analysis.

When to Use

• After adding new skills to ctxharness .claude/skills/
• Before cutting a release (quality gate)
• After bulk-importing skills from another project
• When adding effort fields for the first time

Scoring Criteria (14 pts per skill)

#	Criterion	Max	What is checked
1	name	1	Present, lowercase, hyphens only, matches directory name
2	description	2	Present + has "Use when" / trigger phrasing
3	allowed-tools	2	Present + not overly broad (Bash without scoping when read-only)
4	effort	3	Present (1pt) + appropriate for content (2pt based on inference)
5	content structure	4	Has Purpose/When section (1), has examples/usage (1), has clear workflow (1), no placeholder text (1)
6	bonus	+2	argument-hint present (1), version/author metadata (1)

Thresholds:

• ✅ Good: ≥11/14 (≥80%)
• ⚠️ Needs work: 8–10/14 (60–79%)
• ❌ Fix: <8/14 (<60%)

Effort Level Inference

low — Mechanical execution, no design decisions

Signals: commit, scaffold, generate, format, sync. No sub-agents. Short workflow (<5 steps).

medium — Analysis with bounded scope

Signals: review, triage, analyze, evaluate (single file or bounded scope). May spawn 1-2 sub-agents with predefined scope.

high — Design decisions, adversarial reasoning, cross-system analysis

Signals: architect, threat-model, audit (security), orchestrate (multi-agent). Broad tool access. Spawns multiple sub-agents.

If a skill has effort: already set but the inferred level differs, flag it:

⚠️ Effort mismatch: declared low, inferred high

Execution Instructions

Step 1 — Discovery

find .claude/skills -name "SKILL.md" 2>/dev/null
find .claude/skills -maxdepth 1 -name "*.md" ! -name "README*" 2>/dev/null

Step 2 — Parse each skill

For each skill file:

1. Read the full file
2. Extract YAML frontmatter
3. Parse: name, description, allowed-tools, effort, argument-hint
4. Read body for structure analysis

Step 3 — Score and infer

Apply scoring criteria. Infer effort from content. Compare vs declared effort if set.

Step 4 — Output report
