Read AGENTS.md first. It is the canonical AI instruction file for this repository.
Then read .ai/context/index.md and choose the smallest task-specific context pack. Use .ai/context/package-routing.md when paths, packages, or a diff are known. Escalate to deeper .ai/*.md references only when the selected pack or .ai/context/accuracy-guardrails.md requires it.
Always read the affected package package.json and package-local AI.md, if present, before changing package code.
