Layering

Keep durable structural rules in AGENTS.md and CLAUDE.md.
Use SKILL.md only for repeatable workflows, debugging playbooks, and migration checklists that would otherwise bloat directory-level rules.
Backend module AGENTS.md files may point here or to focused skills under src/api/skills/.

Backend Skill Index

skills/shifu-authoring-flow/SKILL.md
skills/user-auth-flows/SKILL.md

When To Add A Skill

Add a focused backend skill when the same provider, auth, streaming, or persistence workflow is repeated across multiple tasks.
Keep each skill actionable: trigger, core rules, workflow, and regression checklist.
