# Planning Skill

Umbrella skill for the planning lifecycle. Routes to the correct reference based on the intent requested: write a spec, resolve ambiguities before planning, create a file-backed plan, validate a plan, manage plan lifecycle, pause a session, or resume from handoff artifacts.

## Routing

Detect the user's intent and load the appropriate reference file:

| Intent | Trigger phrases | Reference |
|--------|----------------|-----------|
| **Spec** | "write spec", "user stories", "define requirements", "scope this", "acceptance criteria", "define scope", "spec out" | `${CLAUDE_SKILL_DIR}/references/spec.md` |
| **Pre-plan** | "discuss ambiguities", "resolve gray areas", "clarify before planning", "assumptions mode", "before we plan", "pre-planning discussion" | `${CLAUDE_SKILL_DIR}/references/pre-plan.md` |
| **Interview** | depth-first decision-tree, one question at a time, recommendation per question. Triggers: "interview me", "grill me", "depth-first review", "depth-first interview", "not sure", "i'm not sure", "where do i start", "want clarity on", "need clarity on", "what am i missing", "poke holes in", "challenge my assumptions", "think this through with me", "lots of moving parts", "many decisions" | `${CLAUDE_SKILL_DIR}/references/depth-first-interview.md` |
| **Plan-files** | "create plan", "task plan", "working memory", "persistent plan", "file-backed planning" | `${CLAUDE_SKILL_DIR}/references/plan-files.md` |
| **Check** | "check plan", "validate plan", "plan checker", "review plan", "is this plan ready", "pre-execution check" | `${CLAUDE_SKILL_DIR}/references/check.md` |
| **Manage** | "list plans", "show plan", "complete plan", "plan status", "manage plans" | `${CLAUDE_SKILL_DIR}/references/manage.md` |
| **Pause** | "pause", "save progress", "handoff", "stopping for now", "end session", "session handoff", "wrap up session" | `${CLAUDE_SKILL_DIR}/references/pause.md` |
| **Resume** | "resume", "continue", "pick up where I left off", "what was I doing", "continue work", "where did I leave off", "what's next" | `${CLAUDE_SKILL_DIR}/references/resume.md` |
