Workflows

Workflows enable complex, multi-step AI interactions with state management, conditional logic, and parallel execution.

Overview

SwissArmyHammer workflows are state machines defined in markdown files that can:

• Execute sequences of prompts and shell commands
• Handle conditional branching based on results
• Run actions in parallel for efficiency
• Manage state transitions with validation
• Integrate with git for automated development workflows

Workflow Structure

Workflows are markdown files with YAML front matter:

---
name: code-review-workflow
description: Complete code review process with automated checks
version: "1.0"
initial_state: setup
timeout_ms: 300000
variables:
  - name: project_type
    description: Type of project being reviewed
    default: "web"
  - name: strict_mode
    description: Enable strict review mode
    type: boolean
    default: false
---

# Code Review Workflow

This workflow performs a comprehensive code review process.

## States

### setup
**Description**: Initialize the review process

**Actions:**
- shell: `git status`
- prompt: Use 'code' prompt to get initial assessment
- conditional: Check if tests exist

**Transitions:**
- If tests found → `run-tests`
- If no tests → `static-analysis`

### run-tests
**Description**: Execute the test suite

**Actions:**
- shell: `npm test` (parallel with coverage)
- shell: `cargo test` (if Rust project)

**Transitions:**
- If tests pass → `static-analysis`
- If tests fail → `fix-tests`

### static-analysis
**Description**: Perform static code analysis

**Actions:**
- shell: `cargo clippy` (if Rust)
- shell: `eslint .` (if JavaScript/TypeScript)
- prompt: Use 'review' prompt for manual analysis

**Transitions:**
- Always → `generate-report`

### generate-report
**Description**: Create comprehensive review report

**Actions:**
- prompt: Use 'documentation' prompt to generate report
- shell: `git add review-report.md`

**Transitions:**
- Always → `complete`

### complete
**Description**: Review process completed

    default: false
    
  - name: components
    description: Components to deploy
    type: array
    default: ["api", "web", "worker"]

State Definitions

States define the workflow steps and transitions.

State Structure

### state-name
**Description**: What this state does

**Actions:**
- action-type: action-specification
- action-type: action-specification (parallel)

**Transitions:**
- condition → target-state
- condition → target-state
- Always → default-state

**Error Handling:**
- On error → error-state
- On timeout → timeout-state

Action Types

Prompt Actions

Execute prompts with variables:

**Actions:**
- prompt: code-review language={{project_language}} file={{current_file}}
- prompt: documentation task="generate API docs" format="markdown"

Shell Actions

Run shell commands:

**Actions:**
- shell: `git status`
- shell: `npm test -- --coverage` (timeout: 120s)
- shell: `cargo build --release` (parallel)

Conditional Actions

Make decisions based on conditions:

**Actions:**
- conditional: Check if file exists
  condition: file_exists("package.json")
  true_action: shell: `npm install`
  false_action: skip

Sub-workflow Actions

Call other workflows:

**Actions:**
- workflow: testing-workflow
  variables:
    environment: "{{environment}}"
    strict_mode: true

Wait Actions

Add delays or wait for conditions:

**Actions:**
- wait: 5s
- wait: until file_exists("build/complete.flag")
- wait: until process_finished("background-job")

Transition Conditions

Simple Conditions

**Transitions:**
- Always → next-state
- On success → success-state
- On failure → error-state
- On timeout → timeout-state

Variable-Based Conditions

**Transitions:**
- If environment == "prod" → production-deploy
- If skip_tests == true → deploy
- If test_results.failed > 0 → fix-issues

Command Result Conditions

**Transitions:**
- If last_command.exit_code == 0 → success
- If last_command.output contains "error" → handle-error
- If file_exists("target/release/app") → deploy

Complex Conditions

**Transitions:**
- If (environment == "prod" AND test_results.passed == true) → deploy
- If (file_changed("Cargo.toml") OR dependencies_updated) → rebuild

Execution Model

Sequential Execution

Default behavior - actions run one after another:

**Actions:**
- shell: `cargo build`
- shell: `cargo test`
- prompt: code-review

Parallel Execution

Mark actions for parallel execution:

**Actions:**
- shell: `cargo build` (parallel)
- shell: `npm install` (parallel)

Best Practices

Design Principles

1. Single Responsibility: Each state should have one clear purpose
2. Idempotent Actions: Actions should be safe to retry
3. Error Recovery: Always include error handling paths
4. Resource Cleanup: Clean up resources in error cases
5. Clear Transitions: Make state transitions obvious and documented

Performance Optimization

# Use parallel execution where possible
max_parallel: 4

# Set appropriate timeouts
timeout_ms: 300000

# Minimize state transitions
# Combine related actions in single states

# Cache expensive operations
variables:
  - name: build_cache_key
    value: "{{git.commit}}-{{file_hash('Cargo.toml')}}"

Security Considerations

# Limit allowed commands
allowed_commands: ["git", "cargo", "npm", "docker"]

# Validate inputs
variables:
  - name: branch_name
    pattern: "^[a-zA-Z0-9/_-]+$"

# Use secure credential handling
environment:
  - name: API_TOKEN
    from_env: true
    required: false

## Step-by-Step Workflow Tutorials

### Tutorial 1: Creating Your First Workflow

Let's create a simple issue management workflow from scratch.

#### Step 1: Create the Workflow File

Create `./workflows/issue-workflow.md`:

```bash
mkdir -p ./.swissarmyhammer/workflows
cd ./.swissarmyhammer/workflows

Step 2: Define Basic Structure

---
name: issue-workflow
description: Simple issue creation and tracking workflow
version: "1.0"
initial_state: create_issue
timeout_ms: 60000
variables:
  - name: issue_title
    description: Title for the new issue
    required: true
    type: string
  - name: issue_type
    description: Type of issue
    default: "FEATURE"
    choices: ["FEATURE", "BUG", "TASK"]
---

# Issue Management Workflow

This workflow creates and tracks an issue through completion.

## States

### create_issue
**Description**: Create a new issue

**Actions**:
- Create issue with title and type

**Next**: work_on_issue

### work_on_issue  
**Description**: Switch to working on the issue

**Actions**:
- Start work on the created issue
- Create git branch

**Next**: complete_issue

### complete_issue
**Description**: Mark issue as complete

**Actions**:
- Mark issue as completed
- Merge git branch

**Next**: END

Step 3: Test the Workflow

# Run the workflow
sah flow run issue-workflow --var issue_title="Add user authentication" --var issue_type="FEATURE"

# Check workflow status
sah flow status <run_id>

# View workflow logs
sah flow logs <run_id>

Step 4: Understanding the Output

The workflow will:

1. Create a new issue: FEATURE_001_add-user-authentication
2. Switch to a git branch: issue/FEATURE_001_add-user-authentication
3. Mark the issue as completed when done
4. Merge the branch back to the source branch

Step 5: Customize for Your Needs

Add variables for more control:

variables:
  - name: issue_title
    required: true
    type: string
  - name: issue_type
    default: "FEATURE"
    choices: ["FEATURE", "BUG", "TASK", "REFACTOR"]
  - name: assignee
    description: Person assigned to work on this issue
    type: string
    default: "unassigned"
  - name: priority
    description: Issue priority level
    default: "medium"
    choices: ["low", "medium", "high", "urgent"]

jobs:
  run-workflow:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Install SwissArmyHammer
        run: cargo install swissarmyhammer
      - name: Run CI/CD Workflow
        run: |

        env:
          SLACK_WEBHOOK_URL: ${{ secrets.SLACK_WEBHOOK_URL }}

Tutorial 5: Debugging and Troubleshooting Workflows

Learn to debug workflows effectively.

Step 1: Enable Debug Mode

# Run workflow with debug output
sah flow run my-workflow --debug --var param="value"

# Enable trace logging
RUST_LOG=swissarmyhammer::workflow=trace sah flow run my-workflow

# Step through workflow interactively
sah flow run my-workflow --interactive --var param="value"

Step 2: Common Issues and Solutions

Issue: Workflow gets stuck in a state

# Check current state
sah flow status <run_id>

# View detailed logs
sah flow logs <run_id> --follow

# Manual state transition (emergency)
sah flow transition <run_id> --to-state "next_state"

Issue: Variables not resolving correctly

# Add debug actions to your workflow
**Actions**:
- debug: Print all variables
- debug: Print specific variable values
- conditional: if debug_mode → detailed_logging

Issue: Actions failing silently

# Check action output
sah flow logs <run_id> --filter "action_result"

# Test actions individually
sah flow test my-workflow --dry-run --var param="value"

Step 3: Workflow Validation

# Validate workflow syntax
sah flow validate ./workflows/my-workflow.md

# Check for common issues
sah flow lint ./workflows/my-workflow.md

# Test workflow without execution
sah flow test ./workflows/my-workflow.md --dry-run

Best Practices for Workflow Development

1. Start Simple

• Begin with linear workflows
• Add complexity incrementally
• Test each addition thoroughly

2. State Design Patterns

# Good: Single responsibility states
### validate_input
**Description**: Validate all input parameters
**Actions**: validation_logic_only

### process_data  
**Description**: Process the validated data
**Actions**: processing_logic_only

# Avoid: Multi-purpose states
### validate_and_process
**Description**: Validate input and process data
**Actions**: too_much_complexity

3. Error Handling

# Every state should handle errors
### normal_operation
**Actions**:
- main_action
- on_error → error_handling_state

### error_handling_state
**Actions**:
- log_error
- notify_team
- cleanup_resources
**Transitions**:
- if recoverable → retry_state
- else → failed_state

4. Resource Management

# Always include cleanup
### resource_intensive_task
**Actions**:
- acquire_resources
- main_processing
- cleanup_resources (always runs)

### cleanup_state
**Actions**:
- release_connections
- delete_temporary_files
- update_status

5. Testing Strategies

Unit Test Individual States:

# Test specific workflow state
sah flow test-state my-workflow setup --var param="value"

Integration Testing:

# Test complete workflow path
sah flow test my-workflow --path "setup→process→complete"

Load Testing:

# Run multiple workflow instances
for i in {1..10}; do
  sah flow run my-workflow --var id="$i" &
done
wait

Workflow Monitoring and Metrics

Set up Monitoring

# Monitor all running workflows
sah flow monitor --dashboard

# Get workflow metrics
sah flow metrics --workflow my-workflow --period "last-week"

# Set up alerts
sah flow alert --on-failure --on-timeout --webhook "https://hooks.slack.com/..."

Performance Optimization

# Profile workflow execution
---
enable_profiling: true
collect_metrics: true
---

# Optimize slow states
### slow_state
**Actions**:
- parallel: # Run actions in parallel where possible
  - action_1
  - action_2  
  - action_3
- cache: # Cache expensive computations
  key: "computation_result"
  action: expensive_computation

Workflows provide powerful automation capabilities while maintaining clarity and maintainability through their state machine design. These tutorials provide a solid foundation for creating sophisticated development automation.
