name: skill-archive-safety description: Pre-flight checklist and procedures for archiving, deleting, or migrating Hermes skills. Prevents accidental removal of cron-referenced skills. Covers the 3-layer skill structure and config.yaml management. Includes skill inventory management, promotion workflows, and archival conventions. category: devops

Skill Archive Safety & Management

Skill Inventory Management

Managed vs Unmanaged Skills

• Managed (git-tracked): Live in ~/ai-topics/config/hermes/skills/ — these are version-controlled and syncable
• Unmanaged (local): Live in ~/.hermes/skills/ — these are runtime skills not yet committed to the repo
• Archive convention: Unmanaged skills in .archive subdirectories (e.g., ~/.hermes/skills/.archive/baoyu-comic/) are deprecated but still counted as unmanaged in inventory checks

Promotion Workflow (Unmanaged → Managed)

When new unmanaged skills are identified during inventory checks:

1. Assess value: Does the skill encode reusable workflow knowledge (not session-specific hacks)?
2. Check for duplicates: find ~/ai-topics/config/hermes/skills -type d -name "<skill-name>" — don't promote if a managed version already exists
3. Copy to managed: cp -r ~/.hermes/skills/<category>/<skill-name>/ ~/ai-topics/config/hermes/skills/<category>/<skill-name>/
4. Verify frontmatter: Ensure YAML frontmatter has name, description, category fields
5. Commit: cd ~/ai-topics && git add config/hermes/skills/ && git commit -m "skills: promote <name>" && git push
6. Archive original: Move the local copy to ~/.hermes/skills/.archive/<skill-name>/ to prevent future inventory noise

Inventory Check Commands

# Count managed skills (git-tracked)
find ~/ai-topics/config/hermes/skills -name "SKILL.md" | wc -l

# Count unmanaged skills (local runtime)
find ~/.hermes/skills -name "SKILL.md" | wc -l

# Find archived skills (deprecated but present)
find ~/.hermes/skills/.archive -name "SKILL.md" | wc -l

# Check for skill name collisions (can cause ambiguous load errors)
find ~/.hermes ~/ai-topics/config/hermes/skills -type d | sed 's|/SKILL.md||' | sort | uniq -d

Removal Criteria

Skills should be archived (not deleted) when:

• Superseded by a newer umbrella skill
• Referenced by active cron jobs (check ~/.hermes/cron/jobs.json)
• Contain reusable workflow knowledge not captured elsewhere

Skills can be deleted when:

• One-off session artifacts with no generalizable knowledge
• Fully duplicated in another skill's references/ directory
• Obsolete tool workflows (deprecated APIs, removed features)

CRITICAL: Pre-Flight Checklist

NEVER skip this checklist before ANY skill operation (archive, delete, move, rename).

1. Check cron references (MANDATORY)

python3 -c "
import json
with open('/opt/data/.hermes/cron/jobs.json') as f:
    data = json.load(f)
target = 'TARGET_SKILL'
for j in data['jobs']:
    skills = j.get('skills', [])
    skill = j.get('skill') or ''
    if target in skills or target in skill:
        print(f'BLOCKED: {j[\"name\"]} references {target}')
"

2. Check config.yaml references

grep -r "TARGET_SKILL" ~/.hermes/config.yaml 2>/dev/null

3. Check AGENTS.md / SCHEMA.md references

grep -r "TARGET_SKILL" ~/ai-topics/AGENTS.md ~/ai-topics/wiki/SCHEMA.md 2>/dev/null

4. Check other skills for dependencies

grep -r "TARGET_SKILL" ~/.hermes/skills/*/SKILL.md 2>/dev/null

Rules

1. NEVER archive/delete a skill referenced by any active cron job
2. NEVER archive/delete a skill referenced in AGENTS.md or SCHEMA.md
3. ALWAYS check cron-jobs.json before any skill operation
4. ALWAYS commit skill changes to repo immediately after modification
5. If a skill is referenced but no longer needed, update the cron job FIRST

Recovery Procedure

If a skill was accidentally removed:

1. Check git history: git log --oneline -- config/hermes/skills/SKILL_NAME/
2. Restore: git checkout COMMIT -- config/hermes/skills/SKILL_NAME/
3. Verify cron reference: Run pre-flight checklist above
4. Commit: git commit -m "fix: restore SKILL_NAME (cron-required)"
