+# ProgramGym
+
+ProgramGym is a collection of 1,624 Harbor tasks that evaluate an agent's ability to reproduce software from observed behavior. For each task, the agent receives a reference executable and documentation. It must create an original codebase and a `compile.sh` script that builds a new `./executable` with matching behavior. Copying, wrapping, or decompiling the reference executable is not allowed.
+
+## Task structure
+
+Each task contains:
+
+| Path             | Purpose                                         |
+| ---------------- | ----------------------------------------------- |
+| `task.toml`      | Harbor task metadata and runtime settings.      |
+| `instruction.md` | The task requirements and rules.                |
+| `environment/`   | The agent environment and reference executable. |
+| `tests/`         | The verifier and test fixtures.                 |
+| `solution/`      | Harbor's solution entry point for validation.   |
+
+## Run with Harbor
+
+Requires Docker, a configured model provider, and **Harbor 0.20.0 or newer**. These tasks use Harbor task schema 1.3 and phase-scoped network policies. Run it by Harbor:
+
+```bash
+uv tool install 'harbor>=0.20.0'
+
+harbor run \
+  -d ProgramGym/programgym \
+  -a claude-code \
+  -m your-provider/your-model \
+  -n 4
+```
+
+Replace the model ID and provide the corresponding API credentials. The command runs the full dataset with four concurrent trials; use `-l 1` for a one-task smoke test. Results are written under `jobs/` by default.
