Quick Start

Get up and running in under 5 minutes with these simple examples.

Your First Workflow

1. Initialize Prodigy in your project:

prodigy init

2. Create a simple workflow (fix-tests.yml):

name: fix-failing-tests
steps:
  - shell: "cargo test"
    on_failure:
      claude: "/fix-test-failures"
      max_attempts: 3

3. Run the workflow:

prodigy run fix-tests.yml

Parallel Execution Example

Process multiple files simultaneously with MapReduce:

name: add-documentation
mode: mapreduce

setup:
  - shell: "find src -name '*.rs' -type f > files.json"

map:
  input: files.json
  agent_template:
    - claude: "/add-rust-docs ${item}"
  max_parallel: 10

reduce:
  - claude: "/summarize Documentation added to ${map.successful} files"

Run with:

prodigy run add-documentation.yml

Goal-Seeking Example

Iteratively improve code until all tests pass:

name: achieve-full-coverage
steps:
  - goal_seek:
      goal: "Achieve 100% test coverage"
      command: "claude: /improve-test-coverage"
      validate: "cargo tarpaulin --print-summary | grep '100.00%'"
      max_attempts: 5

Usage

Basic Commands

# Run a workflow
prodigy run workflow.yml

# Execute a single command with retries

    working_dir: ./frontend

Workflow Composition

imports:
  - path: ./common/base.yml
    alias: base

templates:
  test-suite:
    parameters:
      - name: language
        type: string
    steps:
      - shell: "${language} test"

workflows:
  main:
    extends: base.default
    steps:
      - use: test-suite
        with:
          language: cargo

Git Context Variables

Prodigy automatically tracks git changes during workflow execution and provides context variables for accessing file changes, commits, and statistics:

Step-level Variables (Current Step)

• ${step.files_added} - Files added in the current step
• ${step.files_modified} - Files modified in the current step
• ${step.files_deleted} - Files deleted in the current step
• ${step.files_changed} - All files changed (added + modified + deleted)
• ${step.commits} - Commit hashes created in the current step
• ${step.commit_count} - Number of commits in the current step
• ${step.insertions} - Lines inserted in the current step
• ${step.deletions} - Lines deleted in the current step

Workflow-level Variables (Cumulative)

• ${workflow.files_added} - All files added across the workflow
• ${workflow.files_modified} - All files modified across the workflow
• ${workflow.files_deleted} - All files deleted across the workflow
• ${workflow.files_changed} - All files changed across the workflow
• ${workflow.commits} - All commit hashes across the workflow
• ${workflow.commit_count} - Total commits across the workflow
• ${workflow.insertions} - Total lines inserted across the workflow
• ${workflow.deletions} - Total lines deleted across the workflow

Pattern Filtering

Variables support pattern filtering using glob patterns:

# Get only markdown files added
- shell: "echo '${step.files_added:*.md}'"

# Get only Rust source files modified
- claude: "/review ${step.files_modified:*.rs}"

# Get specific directory changes
- shell: "echo '${workflow.files_changed:src/*}'"

Format Modifiers

Control output format with modifiers:

# JSON array format
- shell: "echo '${step.files_added:json}'"  # ["file1.rs", "file2.rs"]

# Newline-separated (for scripts)
- shell: "echo '${step.files_added:lines}'" # file1.rs\nfile2.rs

# Comma-separated
- shell: "echo '${step.files_added:csv}'"   # file1.rs,file2.rs

# Space-separated (default)
- shell: "echo '${step.files_added}'"       # file1.rs file2.rs

Example Usage

name: code-review-workflow
steps:
  # Make changes
  - claude: "/implement feature X"
    commit_required: true

  # Review only the changed Rust files
  - claude: "/review-code ${step.files_modified:*.rs}"

  # Generate changelog for markdown files
  - shell: "echo 'Changed docs:' && echo '${step.files_added:*.md:lines}'"

  # Conditional execution based on changes
  - shell: "cargo test"
    when: "${step.files_modified:*.rs}"  # Only run if Rust files changed

  # Summary at the end
  - claude: |
      /summarize-changes
      Total files changed: ${workflow.files_changed:json}
      Commits created: ${workflow.commit_count}
      Lines added: ${workflow.insertions}
      Lines removed: ${workflow.deletions}

Configuration

Prodigy looks for configuration in these locations (in order):

1. .prodigy/config.yml - Project-specific configuration
2. ~/.config/prodigy/config.yml - User configuration
3. /etc/prodigy/config.yml - System-wide configuration

Example configuration:

# .prodigy/config.yml
claude:
  model: claude-3-opus
  max_tokens: 4096

worktree:
  max_parallel: 20
  cleanup_policy:
    idle_timeout: 300
    max_age: 3600

retry:
  default_attempts: 3
  default_backoff: exponential

storage:
  events_dir: ~/.prodigy/events
  state_dir: ~/.prodigy/state

Examples

Example 1: Automated Testing Pipeline

Fix all test failures automatically with intelligent retry:

name: test-pipeline
steps:
  - shell: "cargo test"
    on_failure:
      - claude: "/analyze-test-failure ${shell.output}"
      - claude: "/fix-test-failure"
      - shell: "cargo test"
    retry:
      attempts: 3
      backoff: exponential

  - shell: "cargo fmt -- --check"
    on_failure: "cargo fmt"

  - shell: "cargo clippy -- -D warnings"
    on_failure:
      claude: "/fix-clippy-warnings"

Example 2: Parallel Code Analysis

Analyze and improve multiple files concurrently:

name: parallel-analysis
mode: mapreduce

setup:
  - shell: |
      find . -name "*.rs" -exec wc -l {} + |
      sort -rn |
      head -20 |
      awk '{print $2}' > complex-files.json

map:
  input: complex-files.json
  agent_template:
    - claude: "/analyze-complexity ${item}"
    - claude: "/suggest-refactoring ${item}"
    - shell: "cargo test --lib $(basename ${item} .rs)"
  max_parallel: 10

reduce:
  - claude: "/generate-refactoring-report ${map.results}"
  - shell: "echo 'Analyzed ${map.total} files, ${map.successful} successful'"

Example 3: Goal-Seeking Optimization

Iteratively improve performance until benchmarks pass:

name: performance-optimization
steps:
  - goal_seek:
      goal: "Reduce benchmark time below 100ms"
      command: "claude: /optimize-performance benches/main.rs"
      validate: |
        cargo bench --bench main |
        grep "time:" |
        awk '{print ($2 < 100) ? "score: 100" : "score: " int(100 - $2)}'
      threshold: 100
      max_attempts: 10
      timeout: 1800

  - shell: "cargo bench --bench main > benchmark-results.txt"
  - claude: "/document-optimization benchmark-results.txt"

Troubleshooting

Common Issues and Solutions

Performance: Workflows running slowly

1. Check parallel execution limits:

prodigy run workflow.yml --max-parallel 20

2. Enable verbose mode to identify bottlenecks:

prodigy run workflow.yml -v

Note: The -v flag also enables Claude streaming JSON output for debugging Claude interactions.

3. Review analytics for optimization opportunities:

prodigy analytics --session <session-id>

Resume: How to recover from interrupted workflows

Prodigy automatically creates checkpoints. To resume:

# List available checkpoints
prodigy checkpoints list

# Resume from latest checkpoint
prodigy resume

# Resume specific workflow
prodigy resume workflow-abc123

MapReduce: Jobs failing with "DLQ not empty"

Review and reprocess failed items:

# View failed items
prodigy dlq view <job-id>

# Reprocess failed items
prodigy dlq retry <job-id> --max-parallel 5

Configuration: Settings not being applied

Check configuration precedence:

# Show effective configuration
prodigy config show

# Validate configuration
prodigy config validate

Installation: Man pages not available

Install man pages manually:

cd prodigy
./scripts/install-man-pages.sh

# Or install to user directory
./scripts/install-man-pages.sh --user

Debugging: Need more information about failures

Enable debug logging:

# Set log level
export RUST_LOG=debug
prodigy run workflow.yml -vv

# View detailed events
prodigy events --job-id <job-id> --verbose

Verbosity: Controlling Claude streaming output

Prodigy provides fine-grained control over Claude interaction visibility:

Default behavior (no flags):

prodigy run workflow.yml
# Shows progress and results, but no Claude JSON streaming output

Verbose mode (-v):

prodigy run workflow.yml -v
# Shows Claude streaming JSON output for debugging interactions

Debug mode (-vv) and trace mode (-vvv):

prodigy run workflow.yml -vv
prodigy run workflow.yml -vvv
# Also shows Claude streaming output plus additional internal logs

Force Claude output (environment override):

PRODIGY_CLAUDE_CONSOLE_OUTPUT=true prodigy run workflow.yml
# Shows Claude streaming output regardless of verbosity level

This allows you to keep normal runs clean while enabling detailed debugging when needed.
