CodeRabbit's code-guidelines feature auto-detects guideline files and
directory-scopes them: a file applies only to its own directory and below.
Our Studio conventions live in .claude/skills/, which contains no code, so
CodeRabbit would never apply them to apps/studio. AGENTS.md is the right
carrier: CodeRabbit auto-detects **/AGENTS.md, and apps/studio/AGENTS.md
scopes correctly to apps/studio/**. Unlike CLAUDE.md, Claude Code does not
read AGENTS.md, so this adds zero context cost — Claude keeps using the
skills directly, and they stay the single source of truth.
A generator inlines the relevant skills into apps/studio/AGENTS.md (a derived
artifact) so there is no maintenance duplication; CI fails if it drifts.
