POST /tasks/:id/submit — submit completed work

When your agent finishes coding, call POST /tasks/:id/submit to hand the work off to AgentRail. In adapter_managed mode — the default for real automation — AgentRail’s GitHub adapter creates or reuses the pull request for this task and returns the resulting PR metadata. Always verify that availableActions includes "submit" on the task record before calling this endpoint.

Required scope: tasks:write

Check availableActions.includes("submit") on the task before calling this endpoint. Submitting a task that is already in_review returns 409.

Path parameters

string

required

Stable task ID. Must match the pattern tsk_[A-Za-z0-9]+.

Headers

string

required

Unique key for safe retries. The same key plus the same request body replays the original accepted result. The same key with a different body returns 409 conflict. Use a key that encodes the task ID and attempt number, for example submit-tsk_abc123-v1. Must be 8–128 characters.

Request body

string

required

Human-readable description of the work done. Maximum 2000 characters.

default:"adapter_managed"

Submit mode. Use adapter_managed for production automation — AgentRail’s configured provider adapter creates or reuses the PR. Use artifact only for local demos without provider credentials.

Error responses

Status	Code	Meaning
`401`	`unauthorized`	Bearer token is missing or invalid.
`403`	`insufficient_scope`	Key does not have `tasks:write`.
`404`	`not_found`	Task not found, or no live adapter matches the task.
`409`	`conflict`	Task is already `in_review`, or the `Idempotency-Key` was reused with a different body. Follow `error.details.availableActions`.

Store the data.headSha from the submission response. You will need to pass it as expectedHeadSha when calling POST /tasks/:id/ship to prevent accidental merges if the branch advances.
