Proof

Proof is a collaborative markdown editor for agents and humans. Use the hosted web API at https://www.proofeditor.ai.

Every write must include by: "ai:<agent-name>" so Proof can track who wrote what.

This skill is web-only. Do not use a local Mac app bridge or localhost:9847 from this skill.

Default Behavior

If the user shares a Proof URL:

• Join the doc immediately.
• Show presence right away.
• Read the current state before editing.
• Work in the Proof doc unless the user explicitly asks you to move elsewhere.

When creating new docs, follow this priority order:

1. If persistent instructions already define a Proof default mode, use it.
2. Otherwise default to collaborative_docs.
