Vibe Agent Instructions

Overview

Give a repository one set of agent instructions that every tool reads, and keep it true to the repository as it is now. AGENTS.md is the source. CLAUDE.md and CLAUDE.local.md are derived from the files that hold the actual text, so no copy exists to drift.

The value of this work is consistency and reduced re-explanation: the same rules reach every agent, and a fact is written once. It is not a correctness or quality claim — no published measurement supports one — so never present the generated files as making an agent produce better code.

This skill is tool-agnostic and AGENTS.md-first. It does not reproduce a Claude-only /init: it writes the shared file first, derives the vendor files from it, and runs a verifiable update mode that ties every changed claim to a repository observation.
