# auto-sprint argument contract Auto-sprint hard-fails on malformed args (`validateSprintArgs` runs first, before any work). Get the shape right before launching. ## Fields | Field | Required | Type | Default | Notes | |-------|----------|------|---------|-------| | `issues` | **yes** | array of strings | -- | Beads issue IDs (sprint roots), e.g. `["BD-1","BD-2"]`. Must be non-empty; every entry a non-empty string. | | `branch` | **yes** | string | -- | Sprint branch name, e.g. `"feat/auth"`. Created from `origin/<base_branch>` if it does not exist. | | `goal` | no | string | `"P1/P2"` | Exit when no open issues at or above this priority. Must be exactly `"P1"`, `"P1/P2"`, or `"P1/P2/P3"`. | | `max_cycles` | no | positive integer | `5` | Hard cycle ceiling. | | `base_branch` | no | string | `"main"` | PR target branch. | | `requirementsFile` | no | string | none | Path to an additional context file for the planner. | | `skip_dolt_push` | no | boolean | `false` | When `true`, skip the Harvest `bd dolt push` step so the sprint never writes to a real Dolt remote. Set this in CI/e2e runs. | Do not invent other fields -- these seven are the whole contract. ## Args must be a JSON OBJECT, not a JSON-encoded string RIGHT -- pass the object itself as the args value: ```json { "issues": ["APM-12"], "branch": "feat/x" } ``` Full example: ```json { "issues": ["BD-1", "BD-2"], "branch": "feat/auth", "goal": "P1/P2", "max_cycles": 5, "base_branch": "main", "requirement
