File contents

Skill Finder & Verifier

Script: python3 /Users/alice/.claude/skills/skill-finder-verifier/scripts/finder.py Baseline: /Users/alice/v/asi/skills/ (upstream plurigrid/asi)

Operations

# Scan all directories, classify every skill
python3 scripts/finder.py scan

# Scan a single location (agents|claude|codex|goose|copilot|openhands)
python3 scripts/finder.py scan claude

# Verify a specific skill's provenance
python3 scripts/finder.py verify ducklake

# Show diff between local and asi version
python3 scripts/finder.py diff basin

Classification

local-only: Not in asi/skills/ at all. Genuinely created here.
modified: Exists in asi but SKILL.md differs. Candidate for "functionally better" evaluation.
identical: Same hash as asi. Batch-installed, unmodified.
identical-md-extra-files: SKILL.md matches but local has additional files (scripts, assets).

Evaluating Modified Skills

When a skill is classified as modified, evaluate whether the changes make it functionally better by loading these 5 skills:

sharp-edges — Does the modified version fix footgun designs or dangerous defaults?
refuse-mediocrity — Does it raise the quality bar vs the generic upstream?
code-review — Are any added scripts well-written and correct?
hogwash-removal — Does it strip filler and add substance?
skill-validation-gf3 — Does it maintain valid skill structure?

A modified skill counts as "functionally better" when it meets 3+ of 5 evaluator criteria:

Adds environment-specific instructions the upstream lacks
Includes working scripts/assets the upstream doesn't have
Fixes incorrect or misleading guidance
Removes generic filler, adds grounded instructions
Maintains valid SKILL.md structure with proper frontmatter

What This Skill Is NOT
