name: coauthor-brief
description: Generate a co-author / collaborator handoff brief for a multi-author, multi-machine project — summarizing what changed since the last brief (git delta), the current state of each artifact (manuscript, analysis, slides), open questions, how to reproduce locally, and any restricted-data access steps. Use when user says "coauthor brief", "handoff brief", "bring my coauthor up to speed", "what changed since last week", "onboard a collaborator", "write a handoff for [name]", or before sending a co-author the repo. NOT a commit or a checkpoint — it is the cross-machine, cross-person summary `meta-governance.md` only partially covers.

# coauthor-brief

This skill's instructions live in [`.claude/skills/coauthor-brief/SKILL.md`](../../../.claude/skills/coauthor-brief/SKILL.md).
Read that file now and follow it, with the files it points to. Read [`AGENTS.md`](../../../AGENTS.md)
first if you have not already.

It was written for Claude Code. Running it from Codex, Antigravity or another agent:

- **Arguments.** Where it says `$ARGUMENTS`, use what the user asked for.
- **Claude Code agents.** Where a step hands work to an agent in `.claude/agents/` (through the
  `Agent` or `Task` tool), read that agent's file and do the step yourself after the main work.
  Tell the user the step was not an independent review: the same agent did both.
- **Claude Code settings.** `allowed-tools`, `model`, `effort`, `argument-hint` and
  `disable-model-invocation` in the source's frontmatter configure Claude Code. Ignore them.
- **Guards.** Claude Code's guard hooks do not run for you. Follow the rules in `AGENTS.md`
  yourself; the git pre-commit gate and CI still apply to your commits.
