Knowledge Sync

Keep skills and documentation in sync with codebase changes.

Announce: "I'm using knowledge-sync to update team knowledge after these changes."

When to Use

• After completing an OpenSpec change (especially refactors)
• When you notice a skill references outdated code
• When a new pattern is established that should be documented
• When asked to run /sync-knowledge

Process

Phase 1: Identify What Changed

Check recent changes:

git log --oneline -20
git diff HEAD~10 --name-only

Categorize changes by domain:

• Database: supabase/db/ changes
• Frontend: src/ changes
• Edge Functions: supabase/functions/ changes
• Config: opencode.jsonc, AGENTS.md, skill changes

Phase 2: Map Changes to Skills

Use the skill-pattern map to identify affected skills:

Phase 3: Analyze Impact

For each affected skill, check:

1. Do code examples still work? Read the actual code, compare to skill examples
2. Are anti-patterns still relevant? Maybe they're now the correct pattern
3. Are new patterns worth documenting? Repeated patterns should be captured
4. Is the description still accurate? Trigger words should match current functionality

Phase 4: Ask Clarifying Questions

If something is confusing, ASK before assuming:

I noticed [observation]. Questions:

1. [Specific question about intent]
2. [Question about whether this is a new pattern]
3. [Question about whether old pattern should be deprecated]

Please clarify before I update the skills.

Phase 5: Propose Updates

Present changes in structured format:

## Skill Updates Required

### [skill-name]

**Reason:** [Why this needs updating]

**Current content (outdated):**

[snippet]

**Proposed content:**

Approve these changes?

Phase 6: Apply Updates (with approval)

After approval:

1. Update the affected SKILL.md files
2. Update references/ if needed
3. Verify skill still loads correctly
4. Summarize what was changed

What NOT to Update

• Workflow skills (openspec-*, executing-tasks, etc.) - These are process, not code
• Glossary entries - Unless domain terms changed meaning
• External API references - Unless we changed how we use them

Creating New Skills

If a new pattern emerges that doesn't fit existing skills:

1. Identify the pattern clearly
2. Check if it should extend an existing skill or be new
3. If new, propose the skill structure:

   skill-name/
   ├── SKILL.md
   └── references/
       └── examples.md
   

4. Get approval before creating

Red Flags

• Don't update based on assumptions - Read the actual code
• Don't remove patterns without asking - They may still be valid
• Don't add every code change - Only patterns worth repeating
• Don't update skills during a refactor - Wait until it's complete
