You received: `/handoff $ARGUMENTS`

Dispatch on the first token of that line:

- If it is `pack`   → Read `${CLAUDE_SKILL_DIR}/instructions/pack.md` and follow it exactly.
- If it is `unpack` → Read `${CLAUDE_SKILL_DIR}/instructions/unpack.md` and follow it exactly.
- If it is `check`  → Read `${CLAUDE_SKILL_DIR}/instructions/check.md` and follow it exactly.
- Otherwise (empty, or any other value) → do NOT guess a subcommand. Print the usage below and stop:

  **`/handoff` needs one subcommand:**
  - **pack** (old session): consolidate and write everything (RESUME-HERE, INTERVIEW), then commit.
  - **unpack** (new session): read everything and answer the interview into ANSWERS.
  - **check** (old session): grade the answers into FEEDBACK, writing corrections or reporting green for the user to relay.
