# Extend Workflow Skill

Create, extend, and manage workflow definitions using the Factory's workflow system architecture:
- **Workflow Creation**: Build new workflows from patterns
- **Workflow Extension**: Enhance existing workflows with new phases
- **Integration Design**: Configure MCP servers and skills for workflows
- **Schema Validation**: Ensure workflows conform to the schema

## Artifacts Used

| Artifact | Path | Purpose |
|----------|------|---------|
| Workflow Template | `templates/workflows/workflow.md.tmpl` | Markdown structure for workflows |
| Workflow Schema | `knowledge/schemas/workflow-schema.json` | Validation rules |
| Workflow Entities | `knowledge/workflow-entities.json` | Entity definitions |
| Workflow Patterns | `knowledge/workflow-patterns.json` | Common patterns |
| MCP Catalog | `knowledge/mcp-servers-catalog.json` | Available tools |
| Skill Catalog | `knowledge/skill-catalog.json` | Available skills |

## When to Use

- User requests a new workflow for a specific task (debugging, deployment, etc.)
- Existing workflow needs enhancement with new phases or steps
- Workflow needs MCP server integration
- New pattern needs to be captured as a reusable workflow
- Generated project needs custom workflows

## Prerequisites

- Understanding of workflow system architecture and entity model
- Familiarity with workflow patterns and common structures
- Knowledge of available MCP servers and their capabilities
- Understanding of skill catalog and how skills integrate into workflows
- Access to workflow schema and template files

## Core Concepts

### Workflow System Architecture

Workflows follow the entity model defined in `knowledge/workflow-entities.json`:

```
Workflow
├── Phases (ordered groups of steps)
│   ├── Steps (atomic operations)
│   │   ├── Skills (reusable capabilities)
│   │   ├── MCP Servers (external tools)
│   │   └── Knowledge (reference data)
│   └── Decision Points (branching logic)
├── State Machine (lifecycle management)
├── Learning Hooks (continuous improvement)
└── Outputs (artifacts produced)
```

### Workflow Lifecycle States

| State | Description |
|-------|-------------|
| `draft` | Being designed, not executable |
| `active` | Ready for execution |
| `executing` | Currently running |
| `paused` | Awaiting input or resources |
| `completed` | Successfully finished |
| `failed` | Terminated with errors |
| `learning` | Post-execution analysis |

## Research Methods

### Method 1: Pattern-Based Creation

Use when: Creating workflow from known patterns

**Steps**:
1. Read existing patterns: `knowledge/workflow-patterns.json`
2. Select applicable pattern (bugfix, feature, code-review, etc.)
3. Customize for specific use case
4. Add project-specific skills and tools

### Method 2: Research-Driven Creation

Use when: Creating workflow for new domain

**Tools**: `web_search`, `read_file`

```
Step 1: web_search("{{domain}} workflow best practices 2026")
Step 2: web_search("{{domain}} automation patterns")
Step 3: Synthesize into workflow structure
```

### Method 3: Existing Workflow Extension

Use when: Enhancing an existing workflow

**Tools**: `read_file`, `search_replace`

```
Step 1: read_file("workflows/{{existing-workflow}}.md")
Step 2: Identify extension points
Step 3: Add new phases/steps
Step 4: Update MCP tools and skills
```

## Creation Procedures

### Procedure A: Create New Workflow

**Trigger**: "Create workflow for {{purpose}}", "Add workflow that {{does_what}}"

**Steps**:

   → Get markdown structure
   ```

9. **Generate Workflow**
   ```
   write("workflows/{{workflow-name}}.md", content)
   ```

10. **Validate Structure**
    - Check all required sections present
    - Verify MCP tools exist in catalog
    - Verify skills exist in catalog
    - Ensure phases have clear outputs

**Output**: `workflows/{workflow-name}.md`

   ```
   read_file("knowledge/workflow-patterns.json")
   → Extract pattern: bugfix, feature, code-review, etc.
   ```

2. **Customize for Project**
   - Replace placeholders with project values
   - Add project-specific tools
   - Configure project-specific skills
   - Set project-specific outputs

3. **Generate Workflow**
   ```

### Procedure D: Create Agent-Specific Workflow

**Trigger**: "Create workflow for {{agent_name}} agent"

**Steps**:

1. **Understand Agent Purpose**
   ```
   read_file(".cursor/agents/{{agent-name}}.md")
   → Extract responsibilities and skills
   ```

2. **Map Agent Skills to Workflow Steps**
   - Each skill becomes potential workflow step
   - Identify orchestration needs
   - Define phase boundaries

3. **Design Workflow**
   - Structure around agent's decision process
   - Include escalation to human/other agents
   - Add learning hooks for improvement

4. **Generate Workflow**
   ```

## Chat Examples

### Example 1: Create Debugging Workflow
```
User: Create a workflow for debugging pipeline failures

Agent: I'll create a comprehensive debugging workflow.

[read_file("knowledge/workflow-patterns.json")] → Check existing patterns
[read_file("knowledge/mcp-servers-catalog.json")] → Available tools
[read_file("knowledge/skill-catalog.json")] → Available skills
[Designs workflow structure]
[write("workflows/operations/debug-pipeline.md", ...)]

Created: workflows/operations/debug-pipeline.md

Phases:
1. Error Detection - Parse logs, identify failure
2. Root Cause Analysis - Trace error origins
3. Resolution Strategy - Plan fix approach
4. Implementation - Apply fixes
5. Verification - Confirm resolution
6. Learning - Capture lessons learned

MCP Tools: github, sentry (if available)
Skills: pipeline-error-fix, tdd

Would you like me to create an agent to execute this workflow?
```

### Example 2: Extend Workflow with Learning
```
User: Add learning hooks to the TDD workflow

Agent: I'll extend the TDD workflow with learning capabilities.

[read_file("workflows/tdd-workflow.md")]
[read_file("knowledge/workflow-entities.json")] → Learning hook structure
[Designs learning extensions]
[search_replace("workflows/tdd-workflow.md", ...)]

Updated: workflows/tdd-workflow.md

Added Learning Hooks:
- After Phase 5 (Refactor): Capture refactoring patterns
- After Phase 7 (Integration): Capture test effectiveness metrics
- On failure: Capture failure patterns for future prevention

Would you like me to create a knowledge file to store learned patterns?
```

### Example 3: Create from Pattern
```
User: Create a bugfix workflow for my SAP project

Agent: I'll create a bugfix workflow customized for SAP.

[read_file("knowledge/workflow-patterns.json")] → bugfix pattern
[read_file("knowledge/sap-grounding-patterns.json")] → SAP-specific
[Customizes pattern for SAP]
[write("workflows/sap-bugfix-workflow.md", ...)]

Created: workflows/sap-bugfix-workflow.md

Customizations for SAP:
- Phase 1 uses SAP documentation MCP
- Grounding phase checks SAP data models
- Implementation follows RAP/ABAP patterns
- Testing uses SAP Unit framework

Tools: atlassian, SAP-documentation
Skills: grounding, bugfix-workflow, sap-development
```

## Summary: What Gets Created

| Extension Type | Output Location | Format |
|----------------|-----------------|--------|
| Workflow | `workflows/{name}.md` | Markdown |
| Agent Workflow | `workflows/{agent}-workflow.md` | Markdown |
| Pattern-Based | `workflows/{pattern}-{project}.md` | Markdown |

## Post-Extension Automation (MANDATORY)

After creating or extending ANY workflow:

### Step 1: Update Manifest (if applicable)

If workflow adds new knowledge:
```
read_file("knowledge/manifest.json")
→ Update if new knowledge file created
```

### Step 2: Update Documentation

```
read_file("docs/reference/WORKFLOW_PATTERNS.md")
→ Add new workflow to catalog if reusable pattern
```

### Step 3: Update Changelog

```
read_file("CHANGELOG.md")
→ Add entry for new/extended workflow
```

### Step 4: Validate Workflow

- Check all referenced MCP tools exist
- Check all referenced skills exist
- Check all referenced knowledge files exist
- Validate phase/step structure

### Step 5: Git Operations (Ask User First)

**ALWAYS ask before git operations**:
```
⚠️ Ready to commit workflow changes:

Created/Modified: [list files]

Proposed commit: feat(workflow): {{description}}

Proceed? (yes/no/commit only)
```

## Best Practices

- **Design workflows with clear entry and exit conditions**: Each phase should have explicit criteria for when it starts and when it's considered complete
- **Include error handling and rollback procedures**: Every workflow should define what happens when steps fail, including how to undo partial changes
- **Document workflow dependencies and requirements**: Clearly list all MCP servers, skills, and knowledge files needed before execution begins
- **Test workflows with representative data before deployment**: Validate workflows with sample inputs that match real-world scenarios to catch issues early
- **Design for observability**: Include learning hooks and decision points that capture metrics and outcomes for continuous improvement
- **Keep workflows focused and composable**: Each workflow should solve one specific problem; combine multiple workflows for complex processes rather than creating monolithic workflows
