Berth: harness-compatible, post-cutoff Python tasks for offline Gemma 4 coding agents
Berth is a set of 653 verified bug-fix and feature tasks from 24 permissively licensed Python libraries. Every task is
packaged in the data layout of the Gemma 4 Developer Agent Competition
harness and installs and tests with no network. The layout covers tasks.jsonl columns, history-free repository
snapshots, and code graphs in the official format.
It is meant as held-out validation and as a training pool for agents built for that harness. The competition's public development set has 129 tasks from 4 repositories.
| Split | Tasks | Pass the official grader | Statement | Use |
|---|---|---|---|---|
core |
301 | 281 | real GitHub issue | evaluation |
extended |
350 | 297 | pull-request description | training |
overlap |
2 | 2 | real issue | also in SWE-rebench; kept apart |
Recommended headline subset: core tasks with harness_compatible == true and post_cutoff == true (209 tasks).
In these, both the issue and the pull request postdate Gemma 4's January 2025 pretraining cutoff, and the task passes the
competition's own grading rules.
How every task was checked
- Fail before, pass after: in a fresh Python 3.13 environment, tests touched by the fix fail without it and pass with it, identically in two runs.
- Offline: inside a network-less namespace, the environment installs only from
wheels/; the empty patch failsFAIL_TO_PASSand the gold patch passes. - Stable: three more gold replays through an agent runner's tools and grader, under parallel load.
- Official grader (
harness_compatible): the harness's own Phase 2 sequence is reproduced offline, withsetup_workspace_test_configand_validate_junit_xmlimported from the competition'sswegemmawheel. The whole target test files must pass with-p no:anyio, and required tests are matched by name prefix. The gold patch must resolve and the empty patch must not.
Tasks failing step 4 are kept and flagged. Most use async test suites, which the official grader cannot run. To
satisfy the official validator's prefix matching, some test ids were removed; they are listed per task in
FAIL_TO_PASS_dropped_validator and PASS_TO_PASS_dropped_validator, and every task keeps at least one
FAIL_TO_PASS test. For 33 tasks, dependencies were resolved as of the fix commit's date
(env_pinned_to_commit_date).

Baselines (core)
- Localization (292 tasks whose fix edits a function or class). BM25 puts a gold function in its top 10 for 64.0% of tasks, against 9.9% for random. Graph propagation trades top-1 function accuracy (−6.9 points) for top-1 file accuracy (+6.5).
- Gemma 4 31B (
gemma-4-31b-it-qat-w4a16-cton Kaggle 4×L4, simple single agent, 20-minute budget, official grading): 19.6% of the 281 compatible tasks, and 22.0% of the 209 post-cutoff ones. In 59% of failures the patch touched none of the files the real fix changes.
