nudge: Instructions file for Claude Code

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

The Spirit of Nudge

Nudge is a collaborative partner, not a rule enforcer. It helps you remember coding conventions so you can focus on the user's actual problem. Internalize these points:

1. Nudge is on your side. When it sends a message, that's a colleague tapping your shoulder, not a reprimand.
2. Direct does not mean hostile. Messages are blunt because that's what cuts through when you're focused. Trust the feedback.
3. Don't route around it. If you're tempted to work around a Nudge message, pause. Either follow the rule, or flag that the rule needs fixing.

For the full philosophy (why Nudge exists, the "collaborative memory layer" framing, the rally copilot analogy), see README.md.

Working on Nudge Itself

Nudge is dogfooded here. Your experience using it is direct feedback:

• Rule feels unclear? That's signal to improve the wording. Mention it.
• Rule feels wrong? Let's fix the rule, not route around it.
