# Training Traces

Supplementary release for the paper *Evaluating Agents Across Runtime Contracts: When Mismatch Costs Efficiency or Quality* (IAEval 2026, the NeurIPS 2026 Workshop on Evaluation of Interactive Agents). This dataset
holds the teacher agent traces used to fine-tune the paper's LoRA adapters (see the
sibling `cap-sweep-eval-data` release and the fourteen adapter repos alongside this one).

6,000 agent traces total (1,000 per family x runtime combination), produced by an LLM
teacher solving each of the paper's three agentic task families -- Opaque Knapsack,
navigation, and rule diagnosis -- under two interpreter runtime conditions. Each config
is a persistent/stateless pair for one family; all six were used to fine-tune the
correspondingly-named LoRA adapters.

## Key terms

- **Persistent runtime**: the Python interpreter keeps all variables alive between
  agent steps. An agent can write `total_weight += w` and it persists to the next turn.
- **Stateless runtime**: the interpreter resets after every step; nothing carries over
  automatically, so the agent must re-establish any state it needs each turn.

## Format

Each line is a `{"messages": [...]}` chat-format record (system / user / assistant /
tool turns) suitable for direct SFT ingestion. Records include the full CodeAct-style
system prompt, task prompt, the agent's code blocks and tool outputs (including tool
exceptions), through to task completion.

## Provenance

Released alongside the paper *Evaluating Agents Across Runtime Contracts: When Mismatch Costs Efficiency or Quality* (IAEval 2026, the NeurIPS 2026 Workshop on Evaluation of Interactive Agents), to reproduce its reported results.
