Collaborate: A Claude Code Skill for Structured, Asynchronous Document Writing with Multi-Agent Handoffs

A developer built collaborate, a Claude Code skill that solves the coordination problem when multiple people write a document in separate Claude conversations. Instead of playing “wait, what did you decide on that section?” via Google Docs, the tool enforces a turn‑based workflow: each time a contributor picks up the document, Claude briefs them in plain English — what changed, what the previous person attempted, and what specific input is needed next. When the contributor finishes, the skill snapshots the document, logs the reasoning behind each change, and notifies the next person via Signal or Slack.

Key Features from the Source

• Turn handoff with reasoning capture: Claude produces a plain‑English summary of decisions, attempted approaches, and unresolved questions before passing the document to the next contributor.
• Parallel section ownership: Multiple writers can work on different sections simultaneously without stepping on each other’s changes.
• Structured critique & challenger/defender mode: Support for decision documents where one Claude instance argues for a position and another critiques it.
• Round robin review: Automatically cycles through contributors for sequential feedback.
• Storage: Document snapshots are stored on iCloud or Google Drive.
• Notification via Signal or Slack: Each handoff triggers a message to the next person.

Installation

Who It’s For

Teams already using Claude for writing who need structured, asynchronous collaboration — especially useful for policy docs, design specs, or any document where understanding the why behind changes matters as much as the final text.
