local-testing-agent: Instructions file for Claude Code

CLAUDE.md

local-testing-agent CLAUDE.md is an instructions file for Claude Code from marcelkurvers/local-testing-agent. It costs 2,058 tokens per session, scanned A, original, MIT.

Repository instructions for a local testing agent, an MCP server that finds, creates, runs, and reports on software tests in several programming languages.

In plain words
What is it for?
Use it when working on the repository’s test discovery, test generation, parallel test execution, or coverage-reporting features.
Why use it?
It gives coding agents a shared description of the project’s entry points, tools, supported languages, and development workflow.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is marcelkurvers/local-testing-agent's own configuration. It tells Claude Code how to work on local-testing-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything local-testing-agent configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/marcelkurvers/Development/local-testing-agent/.venv/bin/python.

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

local-testing-agent CLAUDE.md 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 2mo 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Overview

This is a local testing agent MCP server that automates test discovery, generation, and execution for multi-language projects. The project provides MCP tools for Claude to scan repositories, generate unit tests, run test suites, and produce coverage reports.

Supported Languages: Python, JavaScript/TypeScript, Go, Rust, Java, Ruby Test Coverage: 91% (120 tests passing) Quality: Production-ready with comprehensive test suite

Architecture

Two Main Entry Points

  1. testing_agent.py - Phase 2 MCP server (latest version)

    • Provides four MCP tools: scan_repository, run_all_tests, run_all_tests_parallel, full_phase2_pipeline
    • New in Session 4: Parallel test execution with configurable concurrency
    • Detects source and test files for 6 languages:
      • Python: *.py files, pytest framework
      • JavaScript/TypeScript: *.js, *.jsx, *.ts, *.tsx files, jest framework
      • Go: *.go files, go test framework
      • Rust: *.rs files, cargo test framework
      • Java: *.java files, Maven/Gradle test frameworks
      • Ruby: *.rb files, RSpec/Minitest frameworks
    • Generates AI test plans and coverage maps
    • Runs language-specific test suites automatically
    • Outputs: .mcp_scan_snapshot.json, .mcp_test_report.json, TEST_COVERAGE_MAP.md, TEST_PLAN_AI.md

  2. testing_engine/ - Phase 1 implementation (older version)

    • Python package with modular components
    • file_scanner.py: Discovers Python source files, excluding venvs and cache dirs
    • unit_test_generator.py: Auto-generates pytest stubs by parsing AST for public functions/methods
    • pipeline.py: Orchestrates scanning → generation → pytest execution with coverage
    • Outputs to .mcp/test_output.log

Key Differences

  • Phase 2 (testing_agent.py): Multi-language support (6 languages), language-specific test framework execution, structured JSON reports, comprehensive detection patterns
  • Phase 1 (testing_engine/): Python-only, always generates tests, simpler pipeline

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.
