foxhound empowers LLM agents to seamlessly understand unfamiliar codebases by generating a hierarchical wiki reflective of the repository's structure. It addresses knowledge gaps by enabling agents to ask experienced team members targeted questions, ensuring reliable code modifications.
foxhound is a powerful tool designed to assist Large Language Model (LLM) agents in navigating unfamiliar codebases effectively. LLMs can struggle with understanding the structure of a new repository and often lack the ability to consult with knowledgeable team members. foxhound addresses these challenges through two main components:
| Tool | Problem it Solves | Description |
|---|---|---|
| wikigen | Understanding a new codebase | Generates a comprehensive and navigable wiki that includes summaries, dependency graphs, file indexes, and modification recipes. |
| consult | Seeking guidance before making changes | Identifies code experts based on Git history and facilitates communication by sending questions via Slack. |
How foxhound Works
- wikigen constructs a detailed wiki for the repository, which contains skill files (
CLAUDE.md/AGENTS.md) that inform the LLM on how to navigate the codebase effectively. - The LLM utilizes this wiki to grasp the repository’s structure, dependencies, and common modification practices.
- In scenarios where the LLM encounters unfamiliar code or faces potentially risky changes, consult helps identify the appropriate human expert based on recent activity in the relevant code sections.
- Communication occurs in Slack where the LLM awaits responses to its inquiries, allowing it to incorporate human feedback seamlessly.
This dual functionality efficiently addresses the common issues (80% of the cases) related to code structure comprehension while reserving human expertise for specialized queries (20% of the cases).
Project Structure
The repository is organized as follows:
foxhound/
wikigen/ → Refer to wikigen/README.md for more information
consult/ → Refer to consult/README.md for more information
docs/sprints/ → Sprint planning documents
go.mod → Shared Go module
Documentation
Each tool comes with detailed documentation, including full usage instructions, available flags, examples, and skill file details:
- wikigen/README.md — Detailed information on the wiki generation tool.
- consult/README.md — Complete guide for the expert consultation tool.
Sample Skill Files
The sample-skills/ directory includes example skill files that illustrate how foxhound generates training data for LLM agents, enabling them to navigate the generated wiki and effectively consult with human experts:
- sample-skills/CLAUDE.md — Sample skill file tailored for Claude Code.
- sample-skills/AGENTS.md — Sample skill file tailored for Codex.
With foxhound, LLMs gain crucial insights into repository structures while maintaining access to human knowledge, ultimately leading to more efficient and accurate code modifications.
