# HarFeast OpenEnv Environment

RL training environment for management consulting tasks, built for the [OpenEnv Hackathon](https://github.com/meta-pytorch/OpenEnv) (Mercor APEX-Agents sub-theme).

An LLM agent navigates files, spreadsheets, and data tools to solve 14 multi-step analytical tasks about a fictional food manufacturing company. Answers are scored against deterministic rubrics.

## Actions

| Action | Description |
|--------|-------------|
| `files.list` | List files/directories |
| `files.read` | Read text documents |
| `spreadsheet.read_range` | Read CSV rows/columns |
| `data.filter` | Filter rows by condition |
| `data.group_by` | Group + aggregate |
| `data.add_columns` | Derived columns |
| `data.compute` | Math expression eval |
| `submit` | Submit final answer (scored against rubric) |
