Create steer

Redirect your running or paused coding session.

POST /v1/agent/coding/{session}/steer

Agent → · All API references → · Get started →

Address	`https://api.hanzo.ai/v1/agent/coding/{session}/steer`
Method	`POST`
Operation	`post_agent_coding_by_session_steer`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Redirect your running or paused coding session. The current run keeps its work before starting a follow-up; its status events report the next session. Ownership comes from the authenticated credential, never the request body.

Request

3 fields, body application/json (required).

Field	In	Type	Required	Description
`session`	path	string	yes	Session identifies the running or paused coding session from the path.
`session`	body	string	—	Session identifies the running or paused coding session from the path.
`text`	body	string	—	Text is the new instruction to carry into the follow-up run.

Response

Status	Body	Meaning
`202`	agent.CodingAck	accepted
`default`	problem-details	refused

202 body — 1 field.

Field	In	Type	Always	Description
`ok`	body	boolean	—	OK means the operation was accepted; it does not imply that an associated coding run has finished.

Failure carries the platform error shape — see Errors.

MCP reaches agent through the agent tool, which names its 51 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_agents"
         }
       }
     }'
