Every \"which coding agent is best?\" comparison runs on vibes — this tool systematizes it.\n\n## When to Activate\n\n- Comparing coding agents (Claude Code, Aider, Codex, etc.) on your own codebase\n- Measuring agent performance before adopting a new tool or model\n- Running regression checks when an agent updates its model or tooling\n- Producing data-backed agent selection decisions for a team\n\n## Installation\n\n> **Note:** Install agent-eval from its repository after reviewing the source.\n\n## Core Concepts\n\n### YAML Task Definitions\n\nDefine tasks declaratively. Each task specifies what to do, which files to touch, and how to judge success:\n\n```yaml\nname: add-retry-logic\ndescription: Add exponential backoff retry to the HTTP client\nrepo: ./my-project\nfiles:\n  - src/http_client.py\nprompt: |\n  Add retry logic with exponential backoff to all HTTP requests.\n  Max 3 retries. Initial delay 1s, max delay 30s.\njudge:\n  - type: pytest\n    command: pytest tests/test_http_client.py -v\n  - type: grep\n    pattern: \"exponential_backoff|retry\"\n    files: src/http_client.py\ncommit: \"abc1234\"  # pin to specific commit for reproducibility\n```\n\n### Git Worktree Isolation\n\nEach agent run gets its own git worktree — no Docker required. This provides reproducibility isolation so agents cannot interfere with each other or corrupt the base repo.\n\n### Metrics Collected\n\n| Metric | What It Measures |\n|--------|-----------------|\n| Pass rate | Did the agent produce code that passes the judge? |\n| Cost | API spend per task (when available) |\n| Time | Wall-clock seconds to completion |\n| Consistency | Pass rate across repeated runs (e.g., 3/3 = 100%) |\n\n## Workflow\n\n### 1. Define Tasks\n\nCreate a `tasks/` directory with YAML files, one per task:\n\n```bash\nmkdir tasks\n# Write task definitions (see template above)\n```\n\n### 2. Run Agents\n\nExecute agents against your tasks:\n\n```bash\nagent-eval run --task tasks/add-retry-logic.yaml --agent claude-code --agent aider --runs 3\n```\n\nEach run:\n1. Creates a fresh git worktree from the specified commit\n2. Hands the prompt to the agent\n3. Runs the judge criteria\n4. Records pass/fail, cost, and time\n\n### 3. Compare Results\n\nGenerate a comparison report:\n\n```bash\nagent-eval report --format table\n```\n\n```\nTask: add-retry-logic (3 runs each)\n┌──────────────┬───────────┬────────┬────────┬─────────────┐\n│ Agent        │ Pass Rate │ Cost   │ Time   │ Consistency │\n├──────────────┼───────────┼────────┼────────┼─────────────┤\n│ claude-code  │ 3/3       │ $0.12  │ 45s    │ 100%        │\n│ aider        │ 2/3       │ $0.08  │ 38s    │  67%        │\n└──────────────┴───────────┴────────┴────────┴─────────────┘\n```\n\n## Judge Types\n\n### Code-Based (deterministic)\n\n```yaml\njudge:\n  - type: pytest\n    command: pytest tests/ -v\n  - type: command\n    command: npm run build\n```\n\n### Pattern-Based\n\n```yaml\njudge:\n  - type: grep\n    pattern: \"class.*Retry\"\n    files: src/**/*.py\n```\n\n### Model-Based (LLM-as-judge)\n\n```yaml\njudge:\n  - type: llm\n    prompt: |\n      Does this implementation correctly handle exponential backoff?\n      Check for: max retries, increasing delays, jitter.\n```\n\n## Best Practices\n\n- **Start with 3-5 tasks** that represent your real workload, not toy examples\n- **Run at least 3 trials** per agent to capture variance — agents are non-deterministic\n- **Pin the commit** in your task YAML so results are reproducible across days/weeks\n- **Include at least one deterministic judge** (tests, build) per task — LLM judges add noise\n- **Track cost alongside pass rate** — a 95% agent at 10x the cost may not be the right choice\n- **Version your task definitions** — they are test fixtures, treat them as code\n\n## Links\n\n- Repository: [github.com/joaquinhuigomez/agent-eval](https://github.com/joaquinhuigomez/agent-eval)\n\n## 原文\n- [英語版の原文](../../../../skills/agent-eval/SKILL.md)\n\n## ナビゲーション\n- [日本語ドキュメント一覧](../../README.md)\n- [skills/README.md](../README.md)\n- [貢献ガイド](../../../../CONTRIBUTING.md)\n","tagline":"Head-to-head comparison of coding agents (Claude Code, Aider, Codex, etc.) on custom tasks with pass rate, cost, time, and consistency metrics","category":"coding-agents","tags":["agent-skill"],"author":"loulanyue","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github fast track","sourceDetail":"loulanyue/awesome-claude-notes","creatorName":"loulanyue","creatorUrl":"https://github.com/loulanyue","sourceUrl":"https://github.com/loulanyue/awesome-claude-notes/tree/main/docs/ja-JP/skills/agent-eval","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/loulanyue-agent-eval#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
