Regenerate agent candidate solutions¶

Generate new editable candidate versions based on existing candidates and coverage fields.

POST https://moi.matrixorigin.cn/newmoi/workspaces/{workspace_id}/agent-builder/candidates/{agent_id}/candidate-versions/{candidate_version}/repropose

Preparation before calling¶

First generate the agent candidate solution to obtain the candidate version and source_digest. Prepare a personal access token with access to the target workspace, target workspace ID, agent ID, and release candidate.

The example below uses:

$AI_STUDIO_API_KEY: The actual personal access token, passed through the X-API-Key Header.
$WORKSPACE_ID: Target workspace ID, passed through the X-Workspace-ID Header and also as workspace_id in the path.
$AGENT_ID: Agent ID, as agent_id in the path.
$CANDIDATE_VERSION: The current release candidate, as candidate_version in the path.
$SOURCE_DIGEST: Digest from the current candidate response for source_digest in the request body.

Request example¶

curl -X POST "https://moi.matrixorigin.cn/newmoi/workspaces/$WORKSPACE_ID/agent-builder/candidates/$AGENT_ID/candidate-versions/$CANDIDATE_VERSION/repropose" \
  -H "X-API-Key: $AI_STUDIO_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID" \
  -H 'Content-Type: application/json' \
  -d '{
    "source_digest": "'"$SOURCE_DIGEST"'",
    "overrides": {
      "agent_md": "<UPDATED_AGENT_MD>"
    }
  }'

Path parameters¶

Parameters	Type	Is it required	Description
`workspace_id`	string	Yes	Workspace ID.
`agent_id`	string	Yes	Agent ID.
`candidate_version`	string	Yes	The current release candidate.

Request body¶

Parameters	Type	Is it required	Description
`source_digest`	string	Yes	The digest in the current candidate response, used for concurrent verification.
`overrides`	object	Yes	Candidate fields to overwrite.

Successful response¶

Returns 200 on success. data is a new release candidate; the original candidate does not automatically become a loaded release because the request is accepted.

  "data": {
    "workspace_id": "ws_01",
    "agent_id": "agent_01",
    "candidate_version": "cand_02",

}

The response fields are as follows.

Field	Type	Description
`code`	integer	`0` on success.
`data.candidate_version`	string	The new release candidate and its summary; used when confirming or canceling.
`data.source_digest`	string	The new release candidate and its summary; used when confirming or canceling.
`data.load_version`	string	The loaded version used after the candidate is confirmed.
`data.status`	string	Candidate status, display content, diagnostics, and resolved resource references.
`data.display`	object	Candidate status, display content, diagnostics, and resolved resource references.
`data.diagnostics`	array	Candidate status, display content, diagnostics, and resolved resource references.
`data.resolved_refs`	object	Candidate status, display content, diagnostics, and resolved resource references.

Error response¶

{
  "code": 4,
  "message": "<错误信息>"
}

Common HTTP errors¶

HTTP status code	error code	Common causes	Recommended actions
`400`	`2`（`INVALID_ARGUMENT`）	The coverage field is unknown, the type is invalid, or the requested field is incomplete.	Only submit fields supported by `overrides`.
`401`	`6`（`UNAUTHENTICATED`）	Lack of valid identity credentials.	Check API Key.
`403`	`5`（`PERMISSION_DENIED`）	The current identity does not have permission to revise the candidate.	Check workspace and agent authorizations.
`404`	`3`（`NOT_FOUND`）	Release candidate does not exist.	Check for release candidates.
`409`	`4`（`ALREADY_EXISTS`）	`source_digest` has expired, the candidate has been replaced, or there is a concurrent authoring conflict.	Generate again after reading the latest candidate.
`500`	`1`（`INTERNAL`）	Candidate build failed.	Try again later.
`503`	`15`（`UNAVAILABLE`）	Agent construction or authorization services are temporarily unavailable.	Try again later.

Follow-up operations¶

After checking the new candidate, Confirm agent candidate solutions, or Cancel the agent candidate plan.
