Input Schema ​
| Field | Type | Required | Default | Description |
|---|---|---|---|---|
runner_group_uuid | uuid | Yes | — | UUID of the RunnerGroup this update operates on, picked from the organization's list of runner groups. |
organization_uuid | uuid | Yes | — | UUID of the caller's organization, injected server-side from the authenticated request; scopes the operation to the correct tenant. |
new_desired_count | integer | No | — | Target ASG desired capacity applied by the scale layer; falls back to the RunnerGroup's own desired_count when omitted. |
actor | string | No | — | User or service actor initiating the update. |
dry_run | boolean | No | — | Validate and plan the re-apply without mutating AWS resources when child workflows support it. |
idempotency_key | string | No | — | Caller-supplied idempotency key for safe retries. |
workflow_run_uuid | string | No | — | — |
workflow_run_id | string | No | — | — |
Output Schema ​
| Field | Type | Required | Default | Description |
|---|---|---|---|---|
runner_group_uuid | uuid | No | — | UUID of the RunnerGroup this action operates on, picked from the organization's list of runner groups; echoed on output alongside terminal/error payloads. |
organization_uuid | uuid | No | — | UUID of the caller's organization, injected server-side from the authenticated request; scopes the operation to the correct tenant. Echoed on output alongside terminal/error payloads. |
runner_execution_uuid | uuid | No | — | UUID of the RunnerExecution this action operates on, picked from the organization's (optionally group-scoped) list of executions; echoed on output alongside terminal/error payloads. |
workflow_uuid | string | No | — | Engine workflow-run identifier (or, for GitHub-Actions-triggered flows, an external GitHub Actions run id) associated with this record; not a platform entity foreign key despite the name. No source is attached since there is no list/query workflow for an internal run id. |
status | string | No | — | — |
outcome | string | No | — | — |
initiated_at | string | No | — | — |
completed_at | string | No | — | — |
failed_at | string | No | — | — |
failure_reason | string | No | — | — |
error | string | No | — | — |
error_type | string | No | — | — |
actor_uuid | uuid | No | — | UUID of the user or service actor who triggered this action, injected server-side from the authenticated request when available; used for audit/attribution only. Optional — omitted for system or service-triggered actions with no human actor. |
reason | string | No | — | — |
workflow_run_uuid | string | No | — | Engine-stamped correlation/run id for this DAG execution (ADR-015/E1 plumbing), written into state_data by action_start; not a foreign key to any business entity. No source is attached since there is no list/query workflow for an internal run id. |
