+# Ouroboros Terminal-Bench 2.0 Pilot Harness
+
+This directory contains a local pilot harness for running the Ouroboros CLI on
+Terminal-Bench 2.0 through Harbor. It is meant to validate that Ouroboros can be
+installed, built, and invoked inside Harbor task containers.
+
+This is not a leaderboard submission package. It does not add audited
+leaderboard metadata or a full ATIF trajectory converter.
+
+## Files
+
+- `ouroboros_tbench_agent.py`: Harbor `BaseInstalledAgent` adapter for
+  Ouroboros.
+- `run-pilot.sh`: local convenience script for a one-concurrency pilot run.
+
+The directory name contains a hyphen, so it is not imported as a Python package.
+`run-pilot.sh` adds this directory to `PYTHONPATH` and imports the adapter as:
+
+```bash
+ouroboros_tbench_agent:OuroborosInstalledAgent
+```
+
+## Prerequisites
+
+- Docker Desktop installed and running.
+- `uv` installed.
+- Network access from task containers for installing Bun and calling the model
+  provider.
+- `OPENAI_API_KEY` exported in the shell.
+
+Optional environment variables:
+
+- `OUROBOROS_TBENCH_MODEL`, default `openai/gpt-5.5`
+- `OUROBOROS_TBENCH_REASONING`, default `medium`
+- `OUROBOROS_TBENCH_MAX_STEPS`, default `50`
+- `OUROBOROS_TBENCH_N_CONCURRENT`, default `1`
+- `OUROBOROS_TBENCH_TIMEOUT_SEC`, default `3600`
+- `OUROBOROS_TBENCH_JOBS_DIR`, default `/private/tmp/ouroboros-tbench/jobs`
+
+## Developer Execution Plan
+
+1. Start Docker Desktop and verify the daemon is reachable:
+
+   ```bash
+   docker info
+   ```
+
+2. Export credentials:
+
+   ```bash
+   export OPENAI_API_KEY=...
+   ```
+
+3. Verify Harbor is available through `uv`:
+
+   ```bash
+   uv tool run harbor --help
+   ```
+
+4. Run the Harbor oracle sanity check:
+
+   ```bash
+   uv tool run harbor run --dataset terminal-bench@2.0 --agent oracle --n-concurrent 1
+   ```
+
+5. Run the Ouroboros pilot:
+
+   ```bash
+   benchmarks/terminal-bench/run-pilot.sh
+   ```
+
+6. Inspect results:
+
+   ```bash
+   ls -la /private/tmp/ouroboros-tbench/jobs
+   ```
+
+   Open the latest Harbor job directory and inspect the trial `agent/`,
+   `verifier/`, `result.json`, and `trial.log` files. Ouroboros logs are written
+   as `agent/ouroboros.txt`, `agent/ouroboros-stdout.txt`, and
+   `agent/ouroboros-stderr.txt`.
+
+## Verification Without Running The Benchmark
+
+Check shell syntax:
+
+```bash
+bash -n benchmarks/terminal-bench/run-pilot.sh
+```
+
+Validate the adapter import:
+
+```bash
+PYTHONPATH=benchmarks/terminal-bench \
+  uv tool run --with harbor python -c "from ouroboros_tbench_agent import OuroborosInstalledAgent; print(OuroborosInstalledAgent.name())"
+```
+
+Run the repo verification suite:
+
+```bash
+bun run verify
+```
+
+## Troubleshooting
+
+### Docker daemon is down
+
+If `docker info` fails, start Docker Desktop and wait until it reports that the
+engine is running.
+
+### `OPENAI_API_KEY` is missing
+
+`run-pilot.sh` exits early when `OPENAI_API_KEY` is empty because the default
+model is `openai/gpt-5.5`.
+
+### Harbor is missing
+
+Use `uv run harbor --help`. If `uv` cannot resolve Harbor, install it with:
+
+```bash
+uv tool install harbor
+```
+
+### Container setup fails while installing Bun
+
+Confirm the task container has outbound network access and can reach
+`https://bun.sh`. Some Terminal-Bench tasks may intentionally restrict internet
+access; those tasks are not suitable for this pilot adapter without pre-baking
+Ouroboros and Bun into the agent image.
+
+### Ouroboros build fails in the task container
+
+Inspect `agent/ouroboros-stderr.txt` and `trial.log` in the latest Harbor job
+directory. The adapter uploads a filtered copy of the current repo and runs
+`bun install` followed by `bun run --filter @ouroboros/cli build`.
