+# Runopsy-Bench
+Twenty labelled agent traces for measuring **failure-onset localization**: given a run
+that went wrong, which step did it start going wrong at — not which step it stopped at.
+Produced for [Runopsy](https://github.com/vahit19/runopsy), an open-source causal failure
+analysis engine for agent runs. `pip install runopsy`.
+## Read this first: these traces are synthetic
+Every case here was **generated, not recorded**. They are single-fault traces written to
+exercise a specific failure mode, with the onset declared by construction rather than
+judged by a person.
+That makes them useful for one thing and useless for another:
+- **Useful** for regression testing and for comparing localization strategies on a fixed,
+  reproducible set. The same code always produces the same numbers.
+- **Useless** as evidence that a tool saves anyone time on real work. A benchmark whose
+  author also wrote the engine measures agreement with its own assumptions.
+If you want human-labelled traces of real agents, use
+[TRAIL](https://huggingface.co/datasets/PatronusAI/TRAIL) or
+[Who&When](https://huggingface.co/datasets/Kevin355/Who_and_When) instead. Runopsy scores
+**0.0%** on both, and that result is published alongside its 94.4% here — see *Results*
+below.
+## Format
+One JSON object per line in `runopsy_bench.jsonl`:
+| field | meaning |
+| --- | --- |
+| `name` | case identifier |
+| `category` | failure taxonomy class (`tool_execution`, `state`, `handoff`, …) |
+| `description` | what the case is meant to represent |
+| `onset_step` | **the ground truth**: sequence number where it started going wrong, or `null` for the healthy case |
+| `affected_steps` | steps the onset plausibly reached |
+| `is_healthy` | true for the one case with nothing wrong, used to measure false positives |
+| `deterministically_detectable` | whether structural analysis alone can reach it |
+| `events` | the trace, as OpenInference-compatible typed events |
+Events carry `run_start`, `tool_call`, `llm_call`, `state_snapshot`, `memory_op`, `claim`,
+`handoff` and `run_end` kinds with hashes rather than payload text.
+## Results
+Measured with `runopsy bench --compare`, reproducible offline:
+| strategy | top-1 | top-3 | mean step distance |
+| --- | ---: | ---: | ---: |
+| no diagnosis | 0.0% | 0.0% | — |
+| blame the last failing step *(what reading a log achieves)* | 22.2% | 44.4% | 3.50 |
+| blame the earliest failing step | 50.0% | 50.0% | 1.31 |
+| Runopsy deterministic engine | **94.4%** | **100.0%** | **0.11** |
+False positive rate on the healthy case: 0.0%.
+**Where the same engine fails**, on labelled traces somebody else annotated:
+| benchmark | onset top-1 |
+| --- | ---: |
+| TRAIL (expert-labelled SWE-Bench agent traces) | 0.0% |
+| Who&When (expert-labelled multi-agent traces) | 0.0% |
+On TRAIL, not one of the 30 annotated onsets carries an error status of any kind — they
+are formatting mistakes, instruction non-compliance, a wrong assumption about a file path.
+Runopsy's deterministic layers read exit codes and tool statuses, so they are blind to
+those by construction. The 94.4% above is on traces where the onset *was itself a
+failure*. Both numbers belong on the same page.
+## Loading
+```python
+import json
+cases = [json.loads(line) for line in open("runopsy_bench.jsonl", encoding="utf-8")]
+print(cases[0]["onset_step"], len(cases[0]["events"]))
+```
+Or with the tool that produced it:
+```bash
+pip install runopsy
+runopsy bench --compare        # reproduces the table above
+```
