Agent Harness Structure

Subdirectory CLAUDE.md files provide scoped guidance. The agent loads only the files relevant to its current working directory.

Directory Layout:

CLAUDE.md                                ← Root: project overview, architecture, shared rules
├── app/

tacoda

app/Actions/CLAUDE.md

This is a real harness file from the project. It tells the agent exactly how to write Action classes.

Actions

Actions encapsulate a single domain operation. They are the primary pattern for complex write operations that go beyond simple CRUD.
