# Workflow capability index Contract format: `1.0.0`
Contract content / skill / extension: `0.1.0` This compact generated index covers supported runtime globals and workflow-tool inputs. For constraints, compatibility behavior, internal boundaries, and dynamic-reference ownership, follow the [exhaustive generated facts](capability-details.md). ## Supported capability index | Name | Classification | Signature | Options and defaults | | --- | --- | --- | --- | | agent | runtime-global | `agent(prompt, options?) => Promise` | `label`: string (optional; default: derived from phase and call count)

`key`: (item: unknown) => string (optional; default: JSON.stringify)
`consecutiveEmpty`: number (optional; default: 2)
