# Add SWE Benchmark

Add a new benchmark task to the bench-swe pipeline from a real GitHub bug-fix.
The human provides the GitHub issue or PR URL; the agent handles extraction,
validation, and file creation.

## Arguments

- **url** (required): GitHub issue or PR URL (e.g.
  `https://github.com/gorilla/mux/issues/534` or
  `https://github.com/gorilla/mux/pull/585`)
- **language** (required): One of: go, python, typescript, javascript, rust,
  ruby, java, c, cpp, php, csharp

## Repository selection criteria

Good benchmark repos are **focused libraries with a clear bug** — not large
applications. Before submitting a URL, prefer repos that are:

- **Size**: < 50 MB and < 800 source files (excludes vendor/node_modules)
- **Dependencies**: < 50 direct dependencies (go.mod, package.json, etc.)
- **Scope**: a library or small service, not a monorepo or full application

The agent will reject repos that exceed these limits.

## Steps

1. Dispatch the `task-curator` agent with the provided arguments. The agent
   will:
   - Validate inputs (URL, language)
   - Check repository size and dependency count (rejects oversized repos)
   - Resolve the fix PR (from issue or directly)
   - Clone the repo, extract base/fix commits, and generate the gold patch
   - Determine the test command from repo conventions
   - Write task JSON to `bench-swe/tasks/{language}/` and patch to
     `bench-swe/patches/`
   - Run 5 inline verification checks (patch applies, files match, no leaks,
     schema completeness, no test files in patch)
   - Fix any issues found during verification

2. Report the result including:
   - Task ID, repo, issue URL
   - Files and lines changed
   - Verification table
