Adds console output to a task's log and answers with how far that log is durable, so the runner knows where to resend from.

Request

8 fields, body application/json (required).

Field	In	Type	Required	Description
`x-runner-uuid`	header	string	—
`x-runner-token`	header	string	—
`index`	body	integer (int64)	—	Index is the position of the first line in that log, so a resent batch overlaps rather than duplicates.
`last`	body	boolean	—	Last seals the log and moves it to storage.
`lines`	body	runner.Line[]	—	Lines is the batch itself.
`lines[].content`	body	string	—	Content is the line itself, without its terminator.
`lines[].time`	body	integer (int64)	—	Time is when the line was written, in unix nanoseconds.
`task`	body	integer (int64)	—	Task is whose log this is.

Response

Status	Body	Meaning
`200`	runner.LogOut	ok
`default`	problem-details	refused

200 body — 1 field.

Field	In	Type	Always	Description
`ack`	body	integer (int64)	—	Ack is how far the log is durable — index plus lines accepted — and where the runner resends from.

Failure carries the platform error shape — see Errors.

MCP reaches git through the git tool, which names its 38 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_git_keys"
         }
       }
     }'
