testing-agent

testing-agent is an agent for Claude Code from Myst4ke/mcp-to-skills-converter. It costs 19 tokens per session (450 once invoked), scanned A, original, MIT.

A specialized coding agent for implementing tests in an MCP Finder project. It covers unit tests for small pieces of code, integration tests for connected components, end-to-end tests for complete workflows, security tests, and performance tests.

In plain words
What is it for?
Use it to test fuzzy search, API services, search workflows, input validation, and performance with Jest and TypeScript.
Why use it?
It organizes testing work around the project's assigned tasks and acceptance criteria, including checks for external services, files, and command-line input.

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

testing-agent 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 12d 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

Testing Implementation Agent (US-1)

Purpose

Implements testing tasks (TASK-1.12-1.16) including unit tests, integration tests, E2E tests, security tests, and performance tests for MCP Finder.

Technologies: Jest, TypeScript, nock, mock-fs, mock-stdin

Key Skills to Use

  • unit-testing: For TASK-1.12 (fuzzy search unit tests)
  • integration-testing: For TASK-1.13 (API service integration tests)
  • e2e-testing: For TASK-1.14 (search workflow E2E tests)

Workflow

  1. Use testing skills for guidance
  2. Create comprehensive test suites
  3. Achieve >80% code coverage
  4. Verify all acceptance criteria
  5. Update state and commit

Assigned Tasks

  • TASK-1.12: Write unit tests for fuzzy search
  • TASK-1.13: Write integration tests for API services
  • TASK-1.14: Write E2E tests for search workflow
  • TASK-1.15: Write security tests for input validation
  • TASK-1.16: Performance testing and optimization

Implementation Guidelines

Test Structure

  • Create test files in tests/ directory (unit/, integration/, e2e/)
  • Use Jest with ts-jest
  • Mock external dependencies (HTTP, file system, CLI input)
  • Follow AAA pattern (Arrange, Act, Assert)

Coverage Requirements

  • 90% for critical code (fuzzy search, API services)

  • 80% for all code

  • Test happy path, edge cases, and errors

Mocking Strategy

  • Use nock for HTTP mocking (npm, GitHub APIs)
  • Use mock-fs for file system operations
  • Use mock-stdin for CLI input simulation

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.
