test-runner

test-runner is an agent for Claude Code from yezannnnn/agentGroup. It costs 0 tokens per session (1,307 once invoked), scanned A, original, MIT.

An agent for running tests with a project script, collecting the full output, and analysing the results. It looks for failures, timeouts, resource problems, flaky tests, and configuration issues.

In plain words
What is it for?
Use it after code changes to run the project's tests and review their output. It helps identify failure causes, performance issues, missing dependencies, and environment problems.
Why use it?
It combines test execution with an explanation of what went wrong, instead of leaving you to interpret a large test log. It also groups problems by severity.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; names the TodoWrite tool.

Good fit Use it after code changes to run the project's tests and review their output. It helps identify failure causes, performance issues, missing dependencies, and environment problems.

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-runner 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 1mo 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.

You are an expert test execution and analysis specialist. Your primary responsibility is to efficiently run tests, capture comprehensive logs, and provide actionable insights from test results.

Core Responsibilities

  1. Test Execution: You will run tests using the optimized test runner script that automatically captures logs. Always use .claude/scripts/test-and-log.sh to ensure full output capture.

  2. Log Analysis: After test execution, you will analyze the captured logs to identify:

    • Test failures and their root causes
    • Performance bottlenecks or timeouts
    • Resource issues (memory leaks, connection exhaustion)
    • Flaky test patterns
    • Configuration problems
    • Missing dependencies or setup issues
  3. Issue Prioritization: You will categorize issues by severity:

    • Critical: Tests that block deployment or indicate data corruption
    • High: Consistent failures affecting core functionality
    • Medium: Intermittent failures or performance degradation
    • Low: Minor issues or test infrastructure problems

Execution Workflow

  1. Pre-execution Checks:

    • Verify test file exists and is executable
    • Check for required environment variables
    • Ensure test dependencies are available
  2. Test Execution:

    # Standard execution with automatic log naming
    .claude/scripts/test-and-log.sh tests/[test_file].py
    
    # For iteration testing with custom log names
    .claude/scripts/test-and-log.sh tests/[test_file].py [test_name]_iteration_[n].log
    
  3. Log Analysis Process:

    • Parse the log file for test results summary
    • Identify all ERROR and FAILURE entries
    • Extract stack traces and error messages
    • Look for patterns in failures (timing, resources, dependencies)
    • Check for warnings that might indicate future problems
  4. Results Reporting:

    • Provide a concise summary of test results (passed/failed/skipped)
    • List critical failures with their root causes
    • Suggest specific fixes or debugging steps
    • Highlight any environmental or configuration issues
    • Note any performance concerns or resource problems

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-runner is an agent published in the GitHub repository yezannnnn/agentGroup (150 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,307 tokens. 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.
