Review Summary
This PR adds the Nebius SWE-rebench OpenHands dataset and fixes a critical issue in the shared OpenHands SFT converter where function_call and observation roles were incorrectly remapped to gpt/human.
Taste Rating: 🟡 Acceptable — Dataset structure follows conventions, but needs evidence that the pipeline actually works.
Key concerns:
- Missing end-to-end pipeline evidence (unit tests alone aren't sufficient per repo guidelines)
- Shared converter change affects all OpenHands datasets — needs careful validation
- Several verification checks needed before merge
See inline comments for details.

🟠 Important: This synthetic terminal message pattern (adding SUCCESS_OBSERVATION + FINISH_MESSAGE when not already present) is a significant transformation that alters the raw trajectory.
Per AGENTS.md: "Preserve the raw trajectory semantics when converting: do not drop repeated actions, consecutive tool calls, observations, failures, rewards, or terminal states unless the PR explains and justifies the filtering."
The PR description should explicitly document:
- What percentage of trajectories needed this synthetic ending?
- Why trajectories marked
resolved=1might not have a finish message? - Whether this affects reproducibility (can users regenerate samples from source and get identical output?)
This isn't necessarily wrong, but it's a significant semantic change that needs clear justification.

🟢 Good change: Removing this role remapping fixes the critical bug where messages containing <function=...> patterns were incorrectly labeled as gpt/human instead of function_call/observation.
However, this is a high-impact shared converter change that affects ALL OpenHands datasets:
🟠 Important: Before merging, verify:
- All existing OpenHands dataset samples in the repo still validate after this change
- Run the full test suite specifically for OpenHands-related tests
- Check if any existing
sample_sft_openhands.jsonfiles were generated with the old (buggy) converter and need regeneration
The fact that 125 tests passed is encouraging, but explicitly confirm no OpenHands-specific regressions were introduced.

Review Summary
This PR adds the Nebius SWE-rebench OpenHands dataset with good structure and comprehensive documentation. However, there are critical issues that must be addressed before merge:
Taste Rating: 🔴 Needs improvement — Missing end-to-end evidence and shared converter change lacks impact verification.
[CRITICAL ISSUES]
🔴 Missing End-to-End Pipeline Evidence
The PR description shows pytest output but no evidence that the actual pipeline works. Per repository guidelines:
"Unit tests alone do NOT count as evidence. Do not accept
pytest, unit test output, or similar test runs as the only proof that the change works."
Required before merge:
Add an Evidence section to the PR description showing:
-
Raw extraction works:
python datasets/nebius_SWE-rebench-openhands-trajectories/extract_raw.py | head -5 | python scripts/jsonl_to_json.py > /tmp/test_raw.json # Show that this produces valid output
-
Standardization works:
cat /tmp/test_raw.json | python scripts/json_to_jsonl.py | python datasets/nebius_SWE-rebench-openhands-trajectories/raw_to_standardized.py | python scripts/jsonl_to_json.py > /tmp/test_std.json # Show that this produces valid standardized trajectories
-
SFT conversion works:
cat /tmp/test_std.json | python scripts/json_to_jsonl.py | python agents/openhands/std_to_sft.py --is_web=no --api_env=execute_bash | python scripts/jsonl_to_json.py > /tmp/test_sft.json # Show that this produces valid SFT format
-
Verification:
- Show the output matches the committed samples
- Demonstrate that
sample_sft.jsonhas correctfromfields for function calls

🟠 Important: This synthetic terminal message pattern (adding SUCCESS_OBSERVATION + FINISH_MESSAGE when not already present) significantly alters the raw trajectory.
Per AGENTS.md: "Preserve the raw trajectory semantics when converting: do not drop repeated actions, consecutive tool calls, observations, failures, rewards, or terminal states unless the PR explains and justifies the filtering."
Issues:
- You're adding data not present in the raw source
- This changes the trajectory structure in a non-reversible way
- The design decision explains the choice but doesn't justify WHY raw trajectories are missing terminal messages
Questions:
- Do raw trajectories from the source actually lack terminal states?
- If so, document this as a dataset quirk in README.md
- If not, fix the extraction to preserve them
- Consider making this transformation optional or documenting it more prominently

🔴 Critical: This is a high-impact shared converter change that affects ALL OpenHands datasets.
Missing verification:
- Have you tested that existing OpenHands dataset samples still validate after this change?
- Are there other datasets that might break?
- What's the evidence that removing this remapping doesn't break existing SFT samples?
Required before merge:
- Run validation tests on ALL existing OpenHands datasets:
python -m pytest tests/test_std_to_sft_conversion.py -v
- Provide evidence (test output + sample comparison) that no existing datasets are broken
- If any datasets DO break, regenerate their
sample_sft.jsonfiles in this PR
Note: The change itself is correct (fixing the function_call/observation role bug), but you must prove it doesn't break existing data.

Review Summary
This PR adds the Nebius SWE-rebench OpenHands dataset with proper structure, comprehensive documentation, and strong evidence of correctness. The Evidence section directly addresses the critical verification concern from previous reviews about the shared converter change.
Taste Rating: 🟡 Acceptable — Dataset follows ADP conventions, shared converter change is well-justified and validated by CI, minor style improvements suggested.
Key Observations
✅ Evidence section resolves blocking concern: The PR now includes CI links showing all checks passed (pre-commit, test suite, docstrings), including cross-dataset regression coverage for the shared std_to_sft.py change.
✅ Design decisions catalog: Comprehensive documentation of filtering choices, action mapping, and terminal message handling.
✅ Complete dataset structure: All required files present (README, extract_raw, raw_to_standardized, schema_raw, api, samples, LICENSE).
🟡 Minor improvements: Type hints and documentation suggestions in inline comments below (non-blocking).
[RISK ASSESSMENT]
- [Overall PR]
⚠️ Risk Assessment: 🟡 MEDIUM
Rationale: This PR modifies a shared converter (agents/openhands/std_to_sft.py) that affects all OpenHands datasets. However, risk is well-mitigated by:
- Comprehensive test coverage (125 passed tests including std_to_sft_conversion and datasets_from_parameter)
- CI validation showing no regressions
- The change actually fixes a bug where function_call/observation roles were incorrectly remapped to gpt/human
- Clear justification and impact analysis in PR description
Recommendation: Safe to merge. The Evidence section provides sufficient proof that existing datasets are not negatively impacted.
VERDICT:
✅ Worth merging: Dataset structure and converter fix are sound, CI validates no regressions, minor style improvements suggested but not blocking.
KEY INSIGHT:
The shared converter change removes role remapping that was producing non-ADP-compliant output — this is a bug fix, not a breaking change. The Evidence section's cross-dataset test coverage confirmation was the missing piece from previous reviews.

Ambiguity: The source contains both successful and unsuccessful trajectories.
Chosen approach: Filter to resolved trajectories in both extraction and standardization.
Example: Rows with
resolved == 1are emitted; unresolved row 0 in the source stream is skipped.Alternatives rejected: Including unresolved trajectories would mix failed attempts into the SFT sample and would not match the successful-trajectory subset described by the dataset card.
Ambiguity: OpenHands
execute_bashcalls can be represented as either API calls or code actions.Chosen approach: Convert them to
CodeAction(language="bash"), matching existing OpenHands trajectory converters.Example:
{"name": "execute_bash", "arguments": "{\"command\": \"pytest\"}"}becomes a bashCodeAction.Alternatives rejected: Keeping
execute_bashas a dataset-specificApiActionwould duplicate the shared OpenHands bash tool behavior.Ambiguity: Assistant
finishtool calls are structured function calls in the raw data but ADP samples often encode finish as a message action.Chosen approach: Convert
finishto aMessageActioncontaining<finish> message </finish>so the shared OpenHands SFT converter emits the canonical finish function call.Example: A raw
finishmessage argument becomes<finish> ... </finish>.Alternatives rejected: Adding a dataset-local SFT converter or preserving
finishas a custom API action would be unnecessary.Ambiguity: The source includes task-tracking tool calls that are not present in every sample.
Chosen approach: Add an
api.pystub fortask_trackerand preserve such calls asApiActions when encountered.Example: Raw
task_trackercalls keep theircommandandtask_listarguments.Alternatives rejected: Dropping task-tracking calls would lose trajectory semantics.
Ambiguity: The shared OpenHands SFT converter remapped
function_callandobservationmessages togptandhumanat the end of conversion.Chosen approach: Remove that remapping so generated samples satisfy current ADP validation and repository guidance.
Example: Generated sample messages containing
<function=...>now retainfrom: "function_call".Alternatives rejected: Post-processing only the new sample JSON would make the sample non-reproducible from the committed converter.
