Best use case

coverage is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Analyze test coverage gaps. Use when user says "test coverage", "what's not tested", "coverage gaps", "missing tests", "coverage report", or "what needs testing".

Teams using coverage should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

You only need a quick one-off answer and do not need a reusable workflow.
You cannot install or maintain the underlying files, dependencies, or repository context.

# Analyze Test Coverage Gaps

Map all testable surfaces in the application and identify what's tested vs. what's missing.

## Steps

### 1. Map Application Surface

Use the `Explore` subagent to catalog:

**Routes/Pages:**
- Scan route definitions (Next.js `app/`, React Router config, Vue Router, etc.)
- List all user-facing pages with their paths

**Components:**
- Identify interactive components (forms, modals, dropdowns, tables)
- Note components with complex state logic

**API Endpoints:**
- Scan API route files or backend controllers
- List all endpoints with their methods

**User Flows:**
- Identify critical paths: auth, checkout, onboarding, core features
- Map multi-step workflows

### 2. Map Existing Tests

Scan all `*.spec.ts` / `*.spec.js` files:

- Extract which pages/routes are covered (by `page.goto()` calls)
- Extract which components are tested (by locator usage)
- Extract which API endpoints are mocked or hit
- Count tests per area

### 3. Generate Coverage Matrix

```
## Coverage Matrix

| Area | Route | Tests | Status |
|---|---|---|---|
| Auth | /login | 5 | ✅ Covered |
| Auth | /register | 0 | ❌ Missing |
| Auth | /forgot-password | 0 | ❌ Missing |
| Dashboard | /dashboard | 3 | ⚠️ Partial (no error states) |
| Settings | /settings | 0 | ❌ Missing |
| Checkout | /checkout | 8 | ✅ Covered |
```

### 4. Prioritize Gaps

Rank uncovered areas by business impact:

1. **Critical** — auth, payment, core features → test first
2. **High** — user-facing CRUD, search, navigation
3. **Medium** — settings, preferences, edge cases
4. **Low** — static pages, about, terms

### 5. Suggest Test Plan

For each gap, recommend:
- Number of tests needed
- Which template from `templates/` to use
- Estimated effort (quick/medium/complex)

```
## Recommended Test Plan

### Priority 1: Critical
1. /register (4 tests) — use auth/registration template — quick
2. /forgot-password (3 tests) — use auth/password-reset template — quick

### Priority 2: High
3. /settings (4 tests) — use settings/ templates — medium
4. Dashboard error states (2 tests) — use dashboard/data-loading template — quick
```

### 6. Auto-Generate (Optional)

Ask user: "Generate tests for the top N gaps? [Yes/No/Pick specific]"

If yes, invoke `/pw:generate` for each gap with the recommended template.

## Output

- Coverage matrix (table format)
- Coverage percentage estimate
- Prioritized gap list with effort estimates
- Option to auto-generate missing tests

Workflow & Productivity

Meeting Prep

3891

from openclaw/skills

Never walk into a meeting unprepared again. Your agent researches all attendees before calendar events—pulling LinkedIn profiles, recent company news, mutual connections, and conversation starters. Generates a briefing doc with talking points, icebreakers, and context so you show up informed and confident. Triggered automatically before meetings or on-demand. Configure research depth, advance timing, and output format. Walking into meetings blind is amateur hour—missed connections, generic small talk, zero leverage. Use when setting up meeting intelligence, researching specific attendees, generating pre-meeting briefs, or automating your prep workflow.

Captures learnings, errors, and corrections to enable continuous improvement. Use when: (1) A command or operation fails unexpectedly, (2) User corrects Claude ('No, that's wrong...', 'Actually...'), (3) User requests a capability that doesn't exist, (4) An external API or tool fails, (5) Claude realizes its knowledge is outdated or incorrect, (6) A better approach is discovered for a recurring task. Also review learnings before major tasks.
