coverage

coverage is a skill for Claude Code from adriannoes/awesome-agentic-ai. It costs 39 tokens per session (676 once invoked), scanned A, original, MIT.

A workflow for finding gaps in an application's automated test coverage. Test coverage describes which pages, components, application programming interfaces, and user journeys have tests.

In plain words
What is it for?
Use it to map the application, compare it with existing tests, and produce a coverage matrix showing missing or weakly tested areas.
Why use it?
It shows what is tested and what is not, so important behavior is less likely to fail unnoticed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

coverage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
