Skill Scorer

Setup

Check if aigent is available:

command -v aigent

With aigent CLI

If aigent is on $PATH, use the CLI for authoritative scoring:

aigent score <skill-directory>

Output shows a 0-100 score with breakdown:

Score: 76/100

Structural (60/60):
  [PASS] SKILL.md exists and is parseable
  [PASS] Name format valid
  ...

Quality (16/40):
  [PASS] Third-person description
  [FAIL] Missing trigger phrase
  ...

Use --format json for machine-readable output.

Exit code 0 means perfect score (100/100). Non-zero means room for improvement.

Without aigent CLI

If aigent is not available, score manually using this checklist.

Structural checks (60 points)

All structural checks must pass to earn 60 points. Any failure zeroes the structural score.

1. SKILL.md exists — file present with valid YAML frontmatter
2. Name format — lowercase, hyphens, digits only; no consecutive hyphens; no leading/trailing hyphens; no reserved words; matches directory name; 64 chars max
3. Description valid — non-empty, 1024 chars max, no XML tags
4. Required fields — name and description present and string-typed
5. No unknown fields — only spec-defined keys in frontmatter
6. Body size — body under 500 lines

Quality checks (40 points, 8 each)

Each passing check earns 8 points.

1. Third-person description — no "I", "me", "my", "you", "your"
2. Trigger phrase — description includes "Use when", "Use for", or similar
3. Gerund name — first segment ends in "-ing" (e.g., "processing-pdfs")
4. Specific name — not generic ("helper", "utils", "tools", etc.)
5. Detailed description — at least 20 characters and 4 words

Scoring formula

total = structural_pass ? 60 : 0
total += quality_checks_passed * 8

Maximum score: 100 (60 structural + 40 quality).
