  or wants to note something for later.

# BTW (By-The-Way) Skill

> Capture improvement suggestions on the fly without disrupting your workflow

## Commands

| Command | Description | Example |
|---------|-------------|---------|
| `/btw "text"` | Record a new suggestion | `/btw "Consider adding input validation to user form"` |
| `/btw list` | Show all collected suggestions | `/btw list` |
| `/btw analyze` | Analyze and categorize suggestions | `/btw analyze` |
| `/btw promote [id]` | Promote suggestion to PDCA feature | `/btw promote 3` |

## How It Works

### Recording a Suggestion

1. Read `.bkit/btw.json` (create if it does not exist)
2. Append a new entry with:
   - `id`: Auto-incrementing integer
   - `text`: The suggestion text
   - `timestamp`: ISO 8601 date string
   - `context`: Current file or feature being worked on
   - `status`: `pending` (default)
   - `category`: Auto-detected (`perf`, `ux`, `refactor`, `security`, `docs`, `other`)
3. Write the updated array back to `.bkit/btw.json` using `write_file`

### Storage Format

```json
{
  "entries": [
    {
      "id": 1,
      "text": "Consider caching API responses for /users endpoint",
      "timestamp": "2026-04-09T14:30:00Z",
      "context": "src/api/users.js",
      "status": "pending",
      "category": "perf"
    }
  ]
}
```

### Listing Suggestions

1. Read `.bkit/btw.json`
2. Display entries in a table sorted by newest first
3. Show status indicators: pending, promoted, dismissed

### Analyzing Suggestions

1. Read all entries from `.bkit/btw.json`
2. Group by category
3. Identify patterns and recurring themes
4. Suggest which items to prioritize
5. Estimate effort for each (low/medium/high)

### Promoting to PDCA Feature

1. Read the specified entry by ID
2. Create a new PDCA plan document: `docs/01-plan/features/{slug}.plan.md`
3. Pre-fill the plan with the suggestion details
4. Update the entry status to `promoted`
5. Inform user to continue with `/pdca design {slug}`

## Categories

| Category | Detection Keywords |
|----------|--------------------|
| `perf` | cache, speed, optimize, slow, performance, latency |
| `ux` | user, UI, UX, interface, experience, accessibility |
| `refactor` | refactor, cleanup, simplify, DRY, extract, reorganize |
| `security` | security, auth, validation, sanitize, XSS, CSRF |
| `docs` | document, README, comment, explain, JSDoc |
| `other` | Everything else |

## Integration with PDCA

BTW feeds into the Act phase:
1. Collect suggestions during Do phase with `/btw "..."`
2. Review collected items with `/btw list`
3. Analyze patterns with `/btw analyze`
4. Promote actionable items with `/btw promote [id]`
5. Continue with standard PDCA flow for promoted items
