+
+## Skill Loading
+
+Before editing files for a substantial task:
+
+- Run `npx @tanstack/intent@latest list` from the workspace root to see available local skills.
+- If a listed skill matches the task, run `npx @tanstack/intent@latest load <package>#<skill>` before changing files.
+- Use the loaded `SKILL.md` guidance while making the change.
+- Monorepos: when working across packages, run the skill check from the workspace root and prefer the local skill for the package being changed.
+- Multiple matches: prefer the most specific local skill for the package or concern you are changing; load additional skills only when the task spans multiple packages or concerns.
