Patch a single node in a workflow definition

Executor-specific config. For agent-task: { template, outputSchema?, agentId?, tags?, priority?, dir?, vcsRepo?, model? }. For swarm-script: { scriptName, scope?, pinHash?, args?, fsMode? }. Values support {{interpolation}} from the node's inputs context. NOTE: config.outputSchema on agent-task nodes validates the AGENT's raw JSON output, while node-level outputSchema validates the EXECUTOR's return value ({taskId, taskOutput}).

REQUIRED for cross-node data access. Maps local names to context paths. Without this, upstream step outputs are NOT available for interpolation — only 'trigger' and 'input' are. Example: { "cityData": "generate-city" } → use {{cityData.taskOutput.field}} in config templates. For trigger data: { "pr": "trigger.pullRequest" }.

JSON Schema to validate resolved inputs before execution

JSON Schema to validate the executor's output (e.g. {taskId, taskOutput} for agent-task). Different from config.outputSchema which validates the agent's raw output.
