+## Scope
+
+Applies to the entire `skills/frontend` tree.
+
+## What lives here
+
+- `SKILL.md` — top-level router for choosing frontend skills.
+- `*/SKILL.md` — specialized frontend skills.
+- `frontend-design/` and `teach-impeccable/` provide shared design-context workflow used by many skills.
+- `.pi/skill-selector.json` contains local skill-selection overrides.
+
+## Working rules
+
+- When adding, renaming, or removing a frontend skill, update root `SKILL.md` so routing stays accurate.
+- Keep frontmatter descriptions trigger-focused: describe **when to use**, not the workflow.
+- Preserve explicit `frontend-design` / `teach-impeccable` prerequisites in child skills when they depend on design context.
+- Prefer concise, searchable wording; this pack is likely to be auto-loaded.
+- When a subtree gains special references or local constraints, add a more specific `AGENTS.md` near that subtree.
+
+## Quick checks
+
+- List skills: `find . -maxdepth 2 -name 'SKILL.md' | sort`
+- Search shared prep rules: `rg -n "Invoke /frontend-design|teach-impeccable|MANDATORY PREPARATION" ./*/SKILL.md`
