Step completed
Record the result and dependencies, then execute the next eligible step.
Platform module
Orchestrator
Coordinate models, tools and people within the same operation. Preserve state and manage errors, retries and review across long-running work.
Workflow orchestration
- Steps and dependencies
- Model and tool calls
- Retry and error paths
- Resume after review
Scope
Its role in the system.
Inside the application
Application workflow
Selected use cases, source information and operational outputs.
Work plan
The work plan defines the objective, steps and dependencies together. Models, tools and people have distinct responsibilities within the same job.

Execution trace
Each step records its input, operation and result. The next step proceeds only when its dependencies are satisfied.

Exception path
Errors can lead to retries, alternative paths or human review. Continuation retains the context of earlier operations.

01 / INPUT
Objective and working scope
Source identity and access scope remain part of the work.
02 / PROCESS
Steps, tools and validation
The module operates within the configured application and control boundaries.
03 / OUTPUT
Result or human review
The next step uses the result with its source and execution context.
Control design
Progress, exceptions and decisions.
Reference behavior for implementation; each deployment needs its own configuration and verification.
Tool did not respond
Distinguish errors from waiting. Define retries according to the action’s impact and tool behavior.
Awaiting a human decision
Present the recommendation, evidence and required decision to the responsible user. Dependent steps wait for review.
01Visible process state
Inputs, operations and results are recorded. When a long-running job stops, completed steps and the point of continuation remain identifiable.
02Governed actions
Data formats, permissions and business rules are checked before tool calls. Steps requiring human judgment are routed for review.
03Errors belong in the workflow
Retry, alternative processing and escalation are explicit paths. Results can be inspected through session records.
Technical operating model
Not a call, but work that can continue
Receiving a model response is different from finishing multi-step work. One step may await a person while another fails. Orchestrator preserves state, dependencies and continuation conditions rather than presenting a failed external call as completed work.
Component relationship / schematic
Step input and state
Distinguish completed, pending and failed work.
Tool call and validation
Evaluate schema, permission and business rules before execution.
Continuation and retry
Define the step to resume after a review decision.
