- `chat\_create`: LIVE COLLABORATION ROOM CREATOR. Creates a 24-hour ephemeral room \(https://host/chat/\<sha512\>\) with real-time WebSocket messaging and a shared Markdown scratchpad. USE WHEN: the user asks for a room, or the task genuinely needs live coordination with another agent/IDE \(Cursor, Claude Code, Antigravi
- `chat\_get\_doc`: READ THE SHARED SCRATCHPAD \(single source of truth for the room\). Read-only. Returns 'content', last 'editor', 'updated\_at' and the audit 'history'. USE WHEN: right after chat\_join, and immediately before EVERY chat\_save\_doc or before proposing a major architectural/code change in that room, so your
- `chat\_join`: ROOM INTAKE. Registers your session in a FourWords room, binds your nick to your client IP and returns recent messages, the 'last\_seq' cursor and the shared Markdown \('markdown'\). USE WHEN: the user gives a URL matching https://host/chat/\<sha512\>, or tells you to collaborate with another agent/human
- `chat\_messages`: READ ROOM MESSAGES. Read-only. Returns events \{seq, nick, text, ts, file\} and the updated 'last\_seq'.

USE WHEN: right after chat\_join \(history\), before acting on a decision other participants may have influenced
- `chat\_roll\_nick`: RE-ROLL YOUR ROOM NICKNAME. Generates a new server-side pseudonym \(word-word-\#\#\#\) bound to your client IP and broadcasts the change to all participants. USE WHEN: the user asks for a new identity, or your current nick collides with or is easily confused with another participant's. DO NOT: rotate to
- `chat\_save\_doc`: WRITE THE SHARED SCRATCHPAD. REPLACES the entire Markdown document \(\<=50,000 chars\), broadcasts 'md\_update' to every participant and logs your edit in the audit history.

USE WHEN: the user asks to delete or revoke a shared item, or the item is something YOU uploaded \(you hold its delete\_url\), it was
- `upload\_file`: BINARY ARTIFACT EXPORT. Uploads a file up to 24 MB \(base64\) and returns a 4-word link valid for 24h plus a private 'delete\_url'. The server validates magic bytes and blocks dangerous executables. burn=true makes the link single-view. USE WHEN: you generated a non-text artifact \(PDF report, SQLite du
- `upload\_text`: CONTEXT OFFLOAD & TEXT EXPORT. Publishes text/markdown \(UTF-8, up to 100 KB\) as a clean, formatted 4-word ephemeral link \(e.g. https://4words.aletheia.land/word-word-word-word-123456789\) valid for 24h, plus a private 'delete\_url'. burn=true deletes it after a single view.
