## Overview

This repository contains two independent FIX utilities: one loads tag names from a FIX XML dictionary, and the other splits and parses FIX fields using a caller-supplied tag-name map. No shown code connects them or identifies a principal application workflow; the package entry point is only a greeting. The README is empty, so broader product capabilities cannot be confirmed. The XML input and FIX-message caller are represented generically because the code accepts caller-provided inputs.

Main entry points: [`fix_tools/dictionary.py`](https://github.com/praney/fix-copilot/blob/main/fix_tools/dictionary.py) (Dictionary loader), [`fix_tools/parser.py`](https://github.com/praney/fix-copilot/blob/main/fix_tools/parser.py) (FIX field parser)

## Connections

- Caller → Dictionary loader: provides path (evidence: `fix_tools/dictionary.py`)
- Dictionary loader → FIX XML dictionary: reads XML (evidence: `fix_tools/dictionary.py`)
- Caller → FIX field parser: provides message and names (evidence: `fix_tools/parser.py`)
