add-tests is a command for coding agents from LarouexNonprofitConsulting/larouex-fullstack-plugin. It costs 0 tokens per session (152 once invoked), scanned A, original, MIT.

A command that generates tests for a software component or API endpoint, including behavior, interactions, errors, accessibility, and edge cases.

In plain words
What is it for?
It helps create Jest tests for React components and APIs, including rendering, user interactions, API calls, exported functions, and accessibility checks.
Why use it?
It reduces the manual work of deciding what to test and setting up mocks, fixtures, assertions, and cleanup.

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

add-tests 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 yesterday.

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.

What it actually says

Generate comprehensive tests for a component or API endpoint.

Create test suite with:

  • Unit tests using Jest and React Testing Library (for components) or Jest (for API)
  • Test file in proper location (tests or .test.ts/.test.tsx)
  • Test setup with necessary mocks and fixtures
  • Render tests for different component states and props
  • Interaction tests (clicks, form input, keyboard navigation)
  • Integration tests for component with API calls
  • Accessibility tests using jest-axe
  • Edge case and error scenario tests
  • Mock implementations for external dependencies
  • Test coverage for all exported functions/components

Include proper test descriptions, assertions, and cleanup. Follow AAA pattern (Arrange, Act, Assert). Ensure tests are isolated and deterministic.

Changes

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.
