What and why

Closes #135

Adds an experimental adapter-side live response collection helper that adapters can call during JobPhase.LOADING_DATA while the longer-term API shape is still being decided.

The helper:

  • reads questions from CSV, JSON, or JSONL inputs
  • calls an OpenAI-compatible /v1/chat/completions endpoint
  • writes responses.jsonl plus manifest.json for evaluation framework loaders
  • records per-row request failures instead of aborting the whole collection run
  • keeps httpx optional via lazy import and supports dependency injection for tests
  • documents the trusted-submitter boundary for endpoint URLs, request headers, and api_key_env

Type

  • feat
  • fix
  • docs
  • refactor / chore
  • test / ci

Testing

  • Tests added or updated
  • Tested manually

Commands run:

uv run ruff check src/evalhub/adapter/live_collection.py src/evalhub/adapter/__init__.py tests/unit/test_live_collection.py
uv run mypy src/evalhub/adapter/live_collection.py tests/unit/test_live_collection.py
uv run pytest tests/unit/test_live_collection.py -q
uv run pytest tests/unit/test_adapter_models.py tests/unit/test_live_collection.py -q

I also ran the full unit suite after uv sync --extra cli --extra mcp --group dev; it reached 492 passed with 2 failures in tests/unit/test_cli_config.py that assert POSIX owner-only permission bits on Windows.

Breaking changes

None.

343-380: 💤 Low value

Consider adding backoff delay between retries.

The retry loop has no delay between attempts, which could be aggressive for transient server issues (e.g., rate limiting). For an experimental feature with max_retries=0 default, this is acceptable, but a short backoff would improve reliability.

💡 Optional: Add exponential backoff

Addressed CodeRabbit's retry backoff nitpick in beebeec.

Changes:

  • added retry_backoff_seconds and max_retry_backoff_seconds to LiveCollectionConfig
  • sleep only between failed row attempts, never after the final attempt
  • documented the capped exponential backoff behavior
  • added a unit assertion that monkeypatches time.sleep and verifies the retry delay

417-421: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Prevent extra_body from overriding the canonical request fields.

body.update(config.extra_body) runs after model and messages are set, so a caller can silently replace the configured model or the loaded prompt payload. That breaks the contract between the on-wire request and the persisted manifest/row metadata. Reserve those keys or merge extra_body first and write the required fields last.

Proposed fix
-    body: dict[str, Any] = {
-        "model": config.model,
-        "messages": messages,
-    }
-    body.update(config.extra_body)
+    forbidden_keys = {"model", "messages"}
+    overlapping_keys = forbidden_keys & config.extra_body.keys()
+    if overlapping_keys:
+        raise ValueError(
+            "extra_body cannot override reserved chat-completions fields: "
+            + ", ".join(sorted(overlapping_keys))
+        )

327-345: ⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Normalize blank JSON/JSONL rows the same way as CSV.

A JSON/JSONL row with "question": "" reaches this helper and raises, which aborts the entire load before any collection happens. _load_csv_questions() skips the same case and also trims whitespace-only IDs, so identical data behaves differently depending on file format. Treat blank question strings as skippable rows and strip raw_id before deciding whether to fall back to row_index.

Pushed 89be251 to address the two live review findings:

  • extra_body no longer overrides canonical model / messages request fields.
  • JSON/JSONL question loading now skips blank questions and normalizes blank IDs consistently with CSV.

Local validation on the pushed commit:

.\.venv\Scripts\ruff.exe check src\evalhub\adapter\live_collection.py tests\unit\test_live_collection.py
.\.venv\Scripts\mypy.exe src\evalhub\adapter\live_collection.py tests\unit\test_live_collection.py
.\.venv\Scripts\pytest.exe tests\unit\test_live_collection.py -q

Result: ruff passed, mypy passed, and 11 passed.

Pushed 04c5563 as a tiny follow-up for the CodeRabbit docstring-coverage warning.

What changed:

  • Added short docstrings to the live collection test stubs and test cases only.
  • No production logic changed.

Result: ruff passed, mypy passed, 11 passed, and git diff --check passed.
