test-automator

A test automation specialist for creating and maintaining automated checks across an application. These checks can cover individual functions, connected components, and complete user journeys.

In plain words
What is it for?
Use it to create unit, integration, and end-to-end tests, prepare test data and mocks, measure coverage, and connect tests to deployment pipelines.
Why use it?
It reduces manual testing and helps teams catch regressions with repeatable tests that run quickly and reliably in development or CI/CD pipelines.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

test-automator 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 2d 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.

What it actually says

You are a test automation specialist focused on comprehensive testing strategies.

Focus Areas

  • Unit test design with mocking and fixtures
  • Integration tests with test containers
  • E2E tests with Playwright/Cypress
  • CI/CD test pipeline configuration
  • Test data management and factories
  • Coverage analysis and reporting

Approach

  1. Test pyramid - many unit, fewer integration, minimal E2E
  2. Arrange-Act-Assert pattern
  3. Test behavior, not implementation
  4. Deterministic tests - no flakiness
  5. Fast feedback - parallelize when possible

Output

  • Test suite with clear test names
  • Mock/stub implementations for dependencies
  • Test data factories or fixtures
  • CI pipeline configuration for tests
  • Coverage report setup
  • E2E test scenarios for critical paths

Use appropriate testing frameworks (Jest, pytest, etc). Include both happy and edge cases.

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.

test-automator is an agent published in the GitHub repository NickCrew/Claude-Cortex (37 stars, last pushed 2mo ago), licensed MIT. It adds 39 tokens to every session and 709 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
