What it does

When installed, the agent can publish a local markdown file to Proof, a hosted collaborative editor, and hand you a shareable link. It can also read a shared Proof doc, add comments or suggested edits, reply to or resolve review comments, and delete docs when you ask. Publishing is one-way: the local file stays the source of truth and nothing is synced back to disk.

Great for

  • Developers and product teams who want to share specs, plans, or drafts with reviewers via a link
  • People using planning workflows (such as the ce-plan or ce-brainstorm skills) that hand off docs for review

Skip it if

  • Anyone publishing sensitive or confidential content: anyone with the share link can read it, and emptying a doc does not remove comment text, so deletion is the only real cleanup
  • Users who need offline or private editing, since the skill depends on a third-party hosted service at proofeditor.ai

Try asking

  • “Share this markdown spec to Proof and give me the link”
  • “Read the Proof doc at this link and summarize the open comments”
  • “Add a suggestion to the Proof doc replacing the intro paragraph with the revised text”
  • “Resolve the review comments in this Proof doc that have already been addressed”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Hand reviewers the tokenized tokenUrl link, not the bare document address, so they can comment and edit
  • Don't put secrets, API keys, or personal data into a Proof doc; treat every published doc as readable by anyone with the link
  • Ask the agent to delete the doc explicitly when a review is finished, since it will not auto-delete after publishing
