improve-expertise
Run self-improve on an expert's mental model to sync with codebase. Use periodically to keep expertise files accurate.
What this skill does
# Improve Expertise
Run the self-improve workflow on an agent expert's expertise file to maintain accuracy.
## Arguments
- `$1`: Domain name (required, e.g., "database", "websocket")
- `$2`: Check git diff flag (optional, "true" or "false", default: "true")
## Instructions
You are running the self-improve workflow to sync an expert's mental model with the actual codebase.
### Step 1: Parse Arguments
Extract:
- Domain name from `$1` (required)
- Check git diff flag from `$2` (optional, default: true)
If no domain provided, STOP and ask for domain name.
### Step 2: Validate Expert Exists
Check if expert directory exists using Glob:
```text
Glob: .claude/commands/experts/{$1}/expertise.yaml
```
If not found:
- STOP and report "Expert not found. Use /tac:create-expert to create it first."
- List available experts using: `Glob: .claude/commands/experts/*`
### Step 3: Spawn Self-Improver Agent
Delegate to the self-improver agent with:
- Domain name
- Path to expertise file: `.claude/commands/experts/{domain}/expertise.yaml`
- Check git diff flag
The agent will:
1. Check git diff (if flag is true)
2. Read current expertise
3. Validate against codebase
4. Identify discrepancies
5. Update expertise file
6. Enforce line limits
7. Validate output
### Step 4: Report Results
Display the self-improve report:
```markdown
## Self-Improve Complete: {domain}
### Changes Made
- [List of changes]
### Expertise Health
| Metric | Value |
| --- | --- |
| Line count | X/1000 |
| Files validated | X/X exist |
| Functions verified | X/X accurate |
### Recommendations
- [Any recommendations for manual review]
```
## Quick Usage
```bash
# Sync after making changes (checks git diff)
/tac:improve-expertise database true
# Full rescan without git diff check
/tac:improve-expertise database false
# Default behavior (checks git diff)
/tac:improve-expertise websocket
```
## When to Run
| Trigger | Command |
| --- | --- |
| After any build/fix work | `/tac:improve-expertise {domain} true` |
| Periodic maintenance | `/tac:improve-expertise {domain} false` |
| Suspect drift | `/tac:improve-expertise {domain} false` |
| Before major planning | `/tac:improve-expertise {domain} false` |
## Notes
- This is the LEARN step of Act-Learn-Reuse
- Run after every ACT (build, fix, modify) step
- Mental model is NOT source of truth - this syncs it with code
- Expertise file must stay under 1000 lines
