Workbench (v3 task set)
An OpenEnv environment that trains workspace habits in a run_bash/submit sandbox:
- explore a large workspace and grep it
- catch the hidden caveat (an amendment, a correction, a note, or a changelog entry)
- compute with code
- verify the result
- write an exact output file or fix code to a spec
It was built for OpenEnv Arena.
- Source: https://github.com/moarshy/workbench
- Image:
ghcr.io/moarshy/workbench:v2(linux/amd64) - Lab notebook: https://github.com/moarshy/openenv-arena-notes
Interface
{"type": "run_bash", "command": "..."}runs as an unprivileged user in/app. Output is capped at 8,192 characters, each command has a 120 s timeout, and there is no network. Available tools: python3 + pandas/numpy/pytest, grep/rg, jq, sqlite3.{"type": "submit", "answer": "..."}ends the task.
An episode allows 12 actions. Reward = 0.5 × (share of checks passed) + 0.5 × (all checks passed).
Tasks (11)
| family | domain | job | caveats |
|---|---|---|---|
| downtime (easy/medium/hard) | industrial | Per-machine unplanned downtime for one shift from a 52k-row sensor log and a 600-line handbook | micro-stop and limit amendments (superseded, future-dated), a night shift across midnight |
| expenses (easy/medium/hard) | office / finance | Audit a department-month of multi-currency claims | cap changes mid-month, a city changing tier, FX corrections, a future-dated rule |
| routing (medium/hard) | math (optimisation) | A two-van VRP within 5% of the optimum | dispatch notes: a forbidden van, a closed road, a cancelled order |
| repair (easy/medium/hard) | software | Fix a 7-module billing package to match its SPEC and CHANGELOG; graded by hidden tests | visible tests catch one bug; the changelog overrides the spec; a decoy that looks off-by-one but is specified |
Calibration (Qwen3.8-27B, thinking off, 8 episodes per task, full-score counts)
downtime 4/3/5 · expenses 4/1/1 · routing –/5/4 · repair 2/2/4 (easy/medium/hard).
These counts understate success. Many failures were empty provider responses or JSON a lenient parser accepts. In v2, the arena's training reward (about 0.8) was well above our calibration.
Verification: independent reference solvers and the documented fix score 1.0. Ignoring the caveats fails. The hidden repair tests run as the sandboxed user, with the expected values kept server-side.
