Use when the user asks to hand off the current session to a new chat, transfer context, or runs /handoff. Creates a self-contained handoff document in the OS temp directory (not the repo) and prints its absolute path.

Compare Claude Code and Codex on the same real code-change task with isolated worktrees, identical gates, transcripts, time, and cost.
Align AGENTS.md, rules, README, plans, and chronicles with the codebase; use --clean to archive obsolete task docs into ATLAS.md.
Research current best practices and turn the evidence into a clear recommendation. Use for state-of-the-art, evidence-based, optimal-approach, comparison, or pros-and-cons questions in any field.
Clarify an ambiguous or consequential change before planning or implementation when more than one sound approach exists.
Add CHANGELOG.md entries, derive them from commits, or cut a Keep a Changelog and SemVer release.
Create a user-requested Conventional Commit from the staged changes.

The doc must stand alone even when a plan/chronicle exists.
Lives in the OS temp dir, NOT the repo (handoffs are short-lived):
${TMPDIR:-/tmp}/claude-handoff-YYYY-MM-DD-HHMMSS-{slug}.md
{slug} = kebab-case topic, from $ARGUMENTS if passed, else inferred from the work.${TMPDIR:-/tmp} via Bash (echo "${TMPDIR:-/tmp}") — macOS uses /var/folders/.../T/, not /tmp.Write to the full absolute path. Fill every section. Empty section → write "None", do NOT delete the header (the new agent's contract depends on the section being present).
# Handoff — YYYY-MM-DD HH:MM — {topic}
### Goal (in the user's own words)
[Intent, quoted.]
### Focus of the next session
[`$ARGUMENTS` as a directive, or "continue from current state".]
### Current State
[File-anchored: working · broken · next step. Files, line numbers, exact errors.]
### Key Decisions
- **[Decision]** — because [reason]. Alternative [name] rejected because [reason].
### Important Context (gotchas · invariants · constraints)
- [Hidden invariants, traps, environment quirks]
### Relevant Files
- `path/to/file.ext` — [what · why · scope]
### Open Questions / Unknowns
- [Unresolved · what the user must decide] (or "None")
### Existing Artifacts (reference by path, do NOT duplicate)
- Plan: `docs/plans/NNNN__...md` — *(one-line summary, or "None")*
- Chronicle: `docs/chronicles/NNNN__...md` — *(or "None")*
- Other: PRDs · ADRs · GitHub issues · open PRs · key commits — *(path/URL each, or "None")*
### Suggested Skills for the New Agent
- `development-skills:<name>` — [why]
### Prompt for New Chat
Read the handoff at: {full absolute path written above}
Then continue from the "Current State" section.
Print HANDOFF WRITTEN: {full absolute path} followed by the doc's "Prompt for New Chat" block (with the path filled in) for the user to paste.
