# AgentTrace

AgentTrace is an open dataset of tool-using language-model agent traces with execution telemetry. Each trace records model-generation steps, tool calls, wall-clock timing, OS-level resource usage, tool inputs and outputs, reasoning content, and reproducibility metadata.

The repository contains the dataset, collection code, analysis scripts, and the deterministic NL2Bash fixture needed to replay the local command-line tasks.

## Dataset Files

| File | Source tasks | Model | Traces |
| --- | --- | --- | ---: |
| `datasets/mbpp_0_6B_20260328T133144Z.jsonl` | MBPP test split | Qwen3-0.6B | 500 |

| `datasets/nl2bash_0_6B_20260328T133144Z.jsonl` | NL2Bash / InterCode curated | Qwen3-0.6B | 200 |
| `datasets/nl2bash_1_7B_20260403T211347Z.jsonl` | NL2Bash / InterCode curated | Qwen3-1.7B | 200 |

Total: 1,400 traces.

## Trace Schema

Each JSONL row is one agent run with:

- `trace_id`, `timestamp_utc`, `prompt`, `model`, `total_duration_ms`
- `spans[]`: tool invocations with `tool_name`, `tool_input`, `tool_output`, timing, exit code, and resource telemetry
- `llm_steps[]`: model-generation steps with visible output, reasoning content, parsed tool calls, and token counts when available
- `metadata`: dataset source, task id, run id, serving configuration, model artifact, platform, hardware, and collection version metadata

Telemetry fields include user CPU time, system CPU time, peak resident-set size, disk read bytes, and disk write bytes. On macOS and Linux, memory accounting differs at the OS API level; the collector normalizes `ru_maxrss` to bytes.

## Quick Start

```bash
uv sync
uv run python analyze.py datasets/mbpp_0_6B_20260328T133144Z.jsonl
uv run python analyze_deep.py datasets/mbpp_0_6B_20260328T133144Z.jsonl datasets/nl2bash_0_6B_20260328T133144Z.jsonl
```

Load the Hugging Face dataset:

```python
import json
from datasets import load_dataset

ds = load_dataset("pagarsky/agent-trace")["train"]
row = ds[0]
spans = json.loads(row["spans_json"])
llm_steps = json.loads(row["llm_steps_json"])
metadata = json.loads(row["metadata_json"])
```

The `data/agenttrace.parquet` file is a normalized convenience view for the Hugging Face dataset viewer and the `datasets` library. The raw release artifacts remain available under `datasets/*.jsonl`.

Generate plots into a local directory:

```bash
uv run python plots.py --outdir figures
```

## Replay And Collection

Start a local `llama-server` compatible with OpenAI-style tool calling, then run:

```bash
./scripts/llama-server.sh start
uv run python collect.py --dataset mbpp -n 10 --model Qwen/Qwen3-0.6B --output datasets/traces.jsonl
uv run python collect.py --dataset nl2bash -n 10 --model Qwen/Qwen3-0.6B --output datasets/traces.jsonl
```

For full runs:

```bash
./scripts/collect-all.sh Qwen/Qwen3-1.7B
```

The NL2Bash tasks use a deterministic fixture under `testdata/`; regenerate or verify it with:

```bash
python scripts/generate-testdata.py --check
python scripts/generate-testdata.py
```

## Data Sources And Licensing

Code in this repository is released under Apache-2.0. The trace dataset is released as openly as possible under the same license, subject to any applicable terms of the upstream prompt sources used to generate traces: MBPP and the curated NL2Bash/InterCode task set. Users should respect the licenses and terms of those upstream datasets.

The traces contain model-generated reasoning and tool outputs. Host-specific paths have been normalized to `/testdata` or redacted placeholders where applicable. A small number of early NL2Bash traces accidentally captured output lines from repo-local files outside the `/testdata` fixture; those line contents are masked with `<redacted ...>` markers, but no trace files or rows were removed.
