Skills Audit
Automated health check that cross-references all skill data sources and reports inconsistencies.
Data Sources
Source
Path
Role
Registry
~/site/skills/claude-skills/registry.yaml
Source of truth for skill definitions
Disk
~/site/skills/claude-skills/skills/*/SKILL.md
Actual skill files
Symlinks
~/.claude/skills/
Installed skills (symlinks to disk)
INDEX
~/.claude/skills/INDEX.md
Human-readable skill catalog
Process
Phase 1: Collect Inventory
Read registry.yaml — extract all name: entries into a list
Glob disk — scan ~/site/skills/claude-skills/skills/*/SKILL.md, extract folder names
List symlinks — ls -la ~/.claude/skills/ to get all symlink entries (exclude INDEX.md, learnings.md, non-directory items)
Read INDEX.md — extract all skill names listed
Phase 2: Registry vs Disk Consistency
Compare registry names against disk folder names:
MISSING from registry: folder exists on disk but no matching entry in registry.yaml
MISSING from disk: entry in registry.yaml but no folder on disk
Phase 3: Symlink Health
For each symlink in ~/.claude/skills/:
Check if symlink target exists (not broken)
Check if the skill name appears in registry.yaml
Reverse check: skills in registry but not installed as symlinks
Report:
BROKEN: symlink target does not exist
NOT IN REGISTRY: installed but not in registry.yaml
NOT INSTALLED: in registry but no symlink
Phase 4: Frontmatter Validation
For each SKILL.md on disk, parse YAML frontmatter and check:
Field
Rule
name
Required. Must be kebab-case. Must match folder name
description
Required. Must be < 1024 chars. No XML angle brackets (<, >). No "claude" or "anthropic" in name field
version
Required. Must exist
user-invocable
Should exist (warn if missing)
Additional checks:
Chinese in prompt body: Scan content below frontmatter for CJK characters (U+4E00-U+9FFF). Flag if found — skill prompts should be English per rules
File size: Warn if SKILL.md exceeds 500 lines
Phase 5: INDEX.md Accuracy
Cross-reference INDEX.md entries against installed symlinks:
Missing from INDEX: skill is installed but not listed in INDEX.md
Stale in INDEX: skill listed in INDEX but not installed
Phase 6: Generate Report
Output the structured report in this format:
## Skills Audit Report**Date**: YYYY-MM-DD
**Skills scanned**: N
### Registry Consistency- OK: X skills consistent
- MISSING from registry: [list or "none"]
- MISSING from disk: [list or "none"]
### Symlink Health- OK: X symlinks valid
- BROKEN: [list or "none"]
- NOT IN REGISTRY: [list or "none"]
- NOT INSTALLED: [list or "none"]
### Frontmatter Issues- [skill-name]: [issue description]
- [skill-name]: [issue description]
- (or "All frontmatter valid")
### INDEX.md Gaps- Missing from INDEX: [list or "none"]
- Stale in INDEX: [list or "none"]
### Summary
Total: X skills on disk, Y in registry, Z installed
Issues found: N
Boundaries
Read-only: This skill does NOT fix issues, only reports them
No auto-commit: Does not create or modify any files
Scope: Only audits ~/site/skills/claude-skills/ and ~/.claude/skills/
If the user asks to fix issues after seeing the report, suggest running skm sync or manual fixes as appropriate
