## Context
These conventions apply to all work on the Squad CLI tool (`create-squad`). Squad is a zero-dependency Node.js package that adds AI agent teams to any project. Understanding these patterns is essential before modifying any Squad source code.
## Patterns
### Zero Dependencies
Squad has zero runtime dependencies. Everything uses Node.js built-ins (`fs`, `path`, `os`, `child_process`). Do not add packages to `dependencies` in `package.json`. This is a hard constraint, not a preference.
### Node.js Built-in Test Runner
Tests use `node:test` and `node:assert/strict` — no test frameworks. Run with `npm test`. Test files live in `test/`. The test command is `node --test test/`.
### Error Handling — `fatal()` Pattern
All user-facing errors use the `fatal(msg)` function which prints a red `✗` prefix and exits with code 1. Never throw unhandled exceptions or print raw stack traces. The global `uncaughtException` handler calls `fatal()` as a safety net.
