ADR WORKFLOW EXECUTOR: State Machine Orchestrated Workflow Execution

ADR-WORKFLOW-EXECUTOR: State Machine Orchestrated Workflow Execution

Status: Accepted Date: 2025-12-18 Deciders: Hal Casteel (Founder/CEO/CTO), CODITECT Core Team Technical Story: Enable declarative workflow definitions as executable state-machine orchestrated multi-agent tasks with research-backed patterns from LangGraph, Azure AI, and AWS Multi-Agent systems.

Context and Problem Statement

CODITECT accumulated 1,149+ workflow JSON files in n8n format across subdirectories, but these workflows existed only as documentation artifacts - they could not be executed. The framework lacked:

Executable workflow definitions - No mechanism to run workflow YAML/JSON as actual orchestrated tasks
State machine orchestration - No formal state transitions between workflow steps
Multi-agent coordination - No way to dispatch workflow nodes to specialized agents
Checkpoint/resume capability - No persistence for long-running workflows
Unified execution model - Different workflow formats without common runtime

The Problem: How do we transform static workflow definitions into executable multi-agent orchestrations while leveraging existing 1,149+ workflow files without modification?

Decision Drivers

Technical Requirements

R1: Execute declarative YAML/JSON workflow definitions as state machines
R2: Support multiple workflow formats (native CODITECT + n8n)
R3: Enable automatic agent dispatch per workflow node type
R4: Provide checkpoint/resume for long-running workflows
R5: Support parallel node execution with join semantics
R6: Integrate with existing 119 CODITECT agents
R7: Enable dry-run mode for workflow validation
R8: Maintain backward compatibility with existing workflow files

Research-Backed Requirements (2024-2025)

RR1: State machine patterns from LangGraph 2025 (graph-based agent orchestration)
RR2: Multi-agent system patterns from Azure AI Agent Design (Microsoft)
RR3: Persistence and recovery from AWS Multi-Agent Systems
RR4: Declarative + imperative hybrid from DevOps.com best practices
RR5: Event-driven patterns from Confluent multi-agent systems

User Experience Goals

UX1: Define workflows in human-readable YAML
UX2: Execute workflows with single command
UX3: Monitor workflow progress in real-time
UX4: Resume failed workflows from last checkpoint
UX5: Validate workflows before execution (dry-run)

Integration Constraints

C1: Must work with existing n8n-format workflow files (1,149+)
C2: Must integrate with CODITECT component activation system
C3: Must support all 7 component types (agents, commands, skills, hooks, scripts, prompts, workflows)
C4: Must work offline (no cloud dependencies)
C5: Must be discoverable via config/component-counts.json

Decision Outcome

Chosen Solution: Implement workflow-executor skill with State Machine Architecture + N8n Adapter Pattern:

State machine execution engine (LangGraph-inspired FSM)
Declarative YAML/JSON workflow schema
N8n adapter for converting existing 1,149+ workflows on-the-fly
Agent dispatch system for node execution
Checkpoint/resume persistence
"Workflow" as 7th component type in activation system

5. Workflow as 7th Component Type

Component Activation System Updates:

Added "workflow" to scripts/update-component-activation.py:

type_mappings = {
    'agent': ('agents', f'{component_name}.md'),
    'command': ('commands', f'{component_name}.md'),
    'skill': ('skills', component_name),
    'hook': ('hooks', f'{component_name}.md'),
    'script': ('scripts', f'{component_name}'),
    'prompt': ('prompts', f'{component_name}.md'),
    'workflow': ('workflows', f'{component_name}.yaml'),  # NEW
}

Added workflow counting to scripts/update-component-counts.py:

# Workflows: workflows/*.yaml + workflows/*.yml + workflows/*.json
workflows_dir = repo_root / "workflows"
if workflows_dir.exists():
    yaml_files = list(workflows_dir.glob("*.yaml"))
    yml_files = list(workflows_dir.glob("*.yml"))
    json_files = [f for f in workflows_dir.glob("*.json")
                 if f.stem.lower() not in ("readme", "index")]
    counts["workflows"] = len(yaml_files) + len(yml_files) + len(json_files)

Current Component Counts (config/component-counts.json):

{
  "counts": {
    "agents": 119,
    "commands": 128,
    "skills": 79,
    "scripts": 195,
    "hooks": 37,
    "prompts": 5,
    "workflows": 3,
    "total": 566
  }
}

Negative Outcomes / Trade-offs

N1: Initial Implementation Complexity

State machine requires careful edge case handling
Agent dispatch integration needs testing
Checkpoint format not yet standardized

N2: n8n Adapter Limitations

Not all n8n node types mapped
Complex n8n expressions may need manual conversion
Connection routing simplified to linear flow

N3: Agent Dependency

Workflow execution depends on agent availability
Agent failures can cascade to workflow failures
Requires robust error handling

Alternatives Considered

Alternative 1: Direct n8n Integration

Pros:

Native n8n execution engine
Full n8n feature support
Active n8n community

Cons:

Requires n8n server deployment (adds infrastructure)
Different execution model from CODITECT
No integration with CODITECT agents
Vendor lock-in to n8n

Rejected: Does not integrate with CODITECT agent ecosystem.

Alternative 2: Temporal.io Workflow Engine

Pros:

Production-grade workflow orchestration
Built-in persistence and replay
Strong typing with SDK

Cons:

Requires Temporal server (significant infrastructure)
Steep learning curve
Overkill for single-user scenarios
External dependency

Rejected: Too heavyweight for CODITECT desktop use case.

Alternative 3: Airflow DAGs

Pros:

Industry standard for data pipelines
Rich operator ecosystem
Scheduling built-in

Cons:

Designed for data pipelines, not agent orchestration
Requires Airflow deployment
Python-only DAG definitions
Poor fit for interactive AI workflows

Rejected: Wrong problem domain (batch vs. interactive).

Alternative 4: Pure Python Orchestration (No FSM)

Pros:

Simple implementation
No formal state machine overhead
Direct Python execution

Cons:

No checkpoint/resume capability
No validation via dry-run
Difficult to visualize workflow state
Ad-hoc error handling

Rejected: Loses state machine benefits (resume, validation, visualization).
