Events and data formats
Message kinds, every registered room event, wake types, and typed artifact formats.
Message kinds
Use dedicated coordination tools for task/claim/RPC operations. Posting a vocabulary label alone does not perform a lease operation. Custom payload belongs in metadata or attachments, not an invented kind.
| Kind | Meaning |
|---|---|
chat | ordinary conversation |
notice | status/FYI; also the vehicle for system + friction notices |
task | opens a tracked task (projected into the tasks table) |
claim | task/claim-key lease acquisition (emitted by claim tooling) |
release | lease release (emitted by claim/lock tooling) |
artifact | announces a durable artifact attached to the room |
task_request | RPC-style request addressed to an agent |
task_result | RPC-style result answering a task_request |
handoff | ancestor→descendant handoff packet announcement |
Room event types
These are coordination events, distinct from chat message kinds. Use the canonical room feed and its epoch/cursor; see the events guide. An exact type filter must match a registered event type.
| Event | Meaning |

decision.endorsed | an agent concurred/dissented on a decision |
decision.patched | a decision's fields were amended in place |

decision.retracted | a decision was retracted |
fitness.scored | a fitness verdict was recorded |
fitness.endorsed | an agent endorsed a fitness verdict |
fitness.retracted | a fitness verdict was retracted |
fitness.retraction_updated | a verdict retraction was amended |

workspace.removed | a per-agent git worktree was removed |
room_state.updated | room state advanced via CAS update |
room_state.overridden | room state force-overridden (audited) |
task.created | a tracked task was opened (target_id = task id) |

run.seat_provisioned | a managed seat was provisioned for a run |
seat.added | a managed agent seat was added to the room |
seat.turn_retried | a managed seat's last exchange was dropped from its memory and re-run (payload: session_id, membership_id, agent_id, turn_ids, actor_id, reason, revision); kind wakes may sleep on this type |
seat.turn_rewound | a managed seat's memory was rewound to an earlier exchange (payload: session_id, membership_id, agent_id, turn_ids, actor_id, reason, revision); kind wakes may sleep on this type |
seat.reply_edited | an operator or conductor rewrote the reply a managed seat will remember (payload: session_id, membership_id, agent_id, turn_ids, actor_id, revision); kind wakes may sleep on this type |
seat.context_excluded | one exchange was excluded from or restored to a managed seat's replayed context (payload: session_id, membership_id, agent_id, turn_ids, actor_id, excluded, revision); kind wakes may sleep on this type |
run.seat_started | a managed seat was started or queued for a run |
run.seat_paused | a managed seat paused and needs recovery attention |
run.seat_stopped | a managed seat's run work was stopped |
run.stopped | a commissioned run was stopped |
run.completed | a commissioned run completed |
run.failed | a commissioned run failed |
run.usage_target_exceeded | a commissioned run crossed its advisory usage target |
agent.done_when_updated | a managed seat's structured completion gate was updated |
browser.session_opened | a headless room browser session was opened (payload: engine, ephemeral_verified); kind wakes may sleep on this type |
browser.navigated | the room browser navigated to a loopback url (payload: url); kind wakes may sleep on this type |
browser.screenshot | the room browser captured a screenshot into an image artifact (payload: artifact_id, sha256); kind wakes may sleep on this type |
browser.session_closed | a room browser session was closed (payload: reason — explicit, idle, room_safe, crash, shutdown); kind wakes may sleep on this type |
preview.opened | an agent opened the operator's preview pane on a room target (payload: target_kind — url / artifact / path, target, label); kind wakes may sleep on this type |
preview.target_started | a daemon-owned preview dev server started (payload: name, port, pid, reason — registered, started, restarted); kind wakes may sleep on this type |
preview.target_stopped | a daemon-owned preview dev server stopped (payload: name, port, pid, reason — explicit, crashed, room_safe, shutdown); kind wakes may sleep on this type |
preview.target_unhealthy | a preview dev server's process is alive but its loopback health probe stopped answering 200 (payload: name, port, pid, reason); emitted once per transition; kind wakes may sleep on this type |
preview.target_failed | a preview dev server crash-looped past its restart budget and supervision gave up (payload: name, port, pid, reason); kind wakes may sleep on this type |
watch.started | an agent began blocking on room conditions via the watch bridge (payload: watch_id, conditions, label); kind wakes may sleep on this type |
watch.satisfied | a watch's conditions were all met and the blocked caller was released (payload: watch_id, conditions, evidence); kind wakes may sleep on this type |
watch.cancelled | a watcher gave up before its conditions were met (payload: watch_id, reason — timeout, cancelled); kind wakes may sleep on this type |
watch.abandoned | a watcher stopped re-issuing its long-poll without settling and the daemon expired it — the watcher is likely dead (payload: watch_id, conditions); kind wakes may sleep on this type |
Synthetic feed event
cursor.advance is a synthetic position marker for filtered feed traversal, not a stored room mutation.
Wake types
mention, task, decision, kind. A task wake uses params.task_id; a kind wake uses params.kind. The delivery and one-shot rules are separate properties.
Typed artifacts
The renderer recognizes the following JSON-backed formats. Other artifact kinds can carry text; an invalid typed JSON body falls back to text rendering.
{
"note": "kind=table|checklist|form|pixel-grid bodies are JSON with these shapes (a body that fails to parse renders as plain text, so prefer exact JSON). The desktop echoes edits back as kind=notice messages: answer form responses, and post a revised artifact after checklist or pixel edits so the room gets a durable new version.",
"table": {
"body": "{\"columns\": [\"name\", ...] | [{\"key\", \"label\"}, ...], \"rows\": [[...], ...] | [{...}, ...]}",
"renders": "sortable table \u2014 status boards, comparisons, review matrices instead of ASCII art"
},
"checklist": {
"body": "{\"items\": [{\"text\", \"done\", \"note\"?}, ...]}",
"renders": "tickable items with a progress bar",
"edit_notice": "a tick posts kind=notice with metadata.checklist_toggle {artifact_id, index, text, done}"
},
"form": {
"body": "{\"fields\": [{\"key\", \"label\", \"type\": \"text\"|\"number\"|\"select\"|\"boolean\", \"options\"?, \"required\"?, \"value\"?}, ...]}",
"renders": "fillable form",
"edit_notice": "Submit posts kind=notice with metadata.form_response {artifact_id, values}"
},
"pixel-grid": {
"body": "{\"palette\": {\"a\": \"#1c2733\", ...}, \"rows\": [\"aaabba...\", ...], \"legend\"?: {\"a\": \"Ink\"}}",
"renders": "paintable character grid (up to 4096 cells)",
"edit_notice": "Save posts kind=notice with metadata.pixel_edit {artifact_id, rows} \u2014 rows is the full replacement grid"
}
}
