Handoff

Distill everything a fresh agent or LLM needs to continue this work — and nothing it doesn't — into a single self-contained markdown document, written to .agent/{branch}/handoff.md and copied to the clipboard.

The reader has zero conversation history. Write for that reader: an LLM picking this up cold, with no access to this chat, these tool results, or your scratch reasoning. Front-load the goal, name every file and command explicitly, and resolve every pronoun.

Workflow

1. Parse the invocation. A free-text focus phrase (e.g. /handoff the auth refactor) scopes the handoff to one thread of work — include only material on that thread. --brief produces a condensed version: Goal + Next steps + top 3 files only. Default is the full document. State the chosen scope in one line before writing.
2. Gather the material from this session into the five section buckets below (Goal, Current state, Plan, Key files, Decisions & gotchas). Pull from what actually happened — files edited, commands run and their results, decisions made — not from what was merely discussed.
3. Curate. Apply the Include / Exclude table. When unsure whether a detail earns its place, ask: would the next agent make a wrong move without it? If no, cut it.
4. Resolve the output path. Run git rev-parse --abbrev-ref HEAD for the branch. Write to .agent/{branch}/handoff.md (create the directory). If the cwd is not a git repo, fall back to .agent/handoff.md, and if .agent/ is not writable, fall back to the scratchpad directory — report which path was used.
5. Write the file from templates/handoff.template.md, filling every section. Omit a section entirely (heading and all) only if it is genuinely empty — never leave a placeholder or a "TODO" in the output.
6. Copy to clipboard. Pipe the file to pbcopy (pbcopy < <path>). If pbcopy is absent (non-macOS or not on PATH), skip it and say so in the report — the file is the primary artifact; the clipboard is a convenience.
7. Report. Print the resolved path, whether the clipboard copy succeeded, and the section count. Do not dump the whole document back into the chat — a one-line pointer plus the path is enough.

Include / Exclude

Examples

Good — a next step the reader can act on

## Plan / next steps
1. Add a `--brief` branch to `src/cli.ts:parseArgs` — mirror the existing
   `--json` flag handling at line 42. Covered by `tests/cli.test.ts`.
2. Run `pnpm test` and confirm the 3 new brief-mode assertions pass.

Bad — vague, assumes shared context

## Plan / next steps
1. Finish the thing we discussed.
2. Fix the other bit and make sure it works.

Anti-patterns (one-liners)

• Dumping the raw conversation instead of curating it.
• Pronouns with no antecedent ("it", "that", "the thing we changed").
• Writing secrets, tokens, or credentials into the file.
• Leaving TODO / placeholder text in a section instead of omitting it.
• Echoing the full handoff back into the chat instead of pointing to the file.

Definition of done

• Scope stated (full / focused / --brief) before writing.
• Output path resolved from the git branch, directory created, path reported.
• Every non-empty section filled from what actually happened this session.
• No secrets, no placeholders, no raw tool transcripts in the file.
• Clipboard copy attempted; success or graceful skip reported.
• One-line pointer (not the whole document) returned to the user.
