Generate a structured handoff document from our current conversation and save it to `claudedocs/handoffs/handoff_YYYYMMDD_HHMMSS.md` (or use the filename provided as `$ARGUMENTS[0]` if given). Create the `claudedocs/handoffs/` directory if it does not exist. ## Document Structure Include exactly these sections: ```markdown # Handoff: [Task Name] - [YYYY-MM-DD HH:MM] ## Task [One sentence: what is being accomplished] ## Scope [What needs to be done. Be specific about boundaries: what is in scope and what is explicitly out of scope] ## Files [All relevant files touched or needed. Format: `path/to/file:line` when a specific line matters] - `src/auth/middleware.ts:45` - token validation logic - `tests/auth.spec.ts` - test suite for this change - `docs/api.md` - needs update after implementation ## Discoveries [Key findings and insights from the work so far. Things the next agent needs to know that are not obvious from the code] - [Discovery 1] - [Discovery 2] ## Work Done [Completed tasks. Append-only: never remove prior entries. Include commit hashes when available] - [x] Task A completed (commit: abc1234) - [x] Task B completed ## Status [Current state: what is done, what remains, test status, blockers] ## Next Steps [Actionable checklist of remaining tasks, in order] 1. [ ] Step 1 2. [ ] Step 2 3. [ ] Step 3 ## Code [Relevant code snippets with context. Focus on the parts a resuming agent needs to understand immediately] \`\`\`typescript // Key impleme...
