CrewAI - Package-Agnostic Crew Runner

A generic CrewAI engine that discovers and runs crews defined in packages' .crewai/ directories.

Quick Start

# List all packages with crews
just crew-list

# Run a specific crew
just crew-run otterfall game_builder --input "Create a QuestComponent"

# Show crew details
just crew-info otterfall game_builder

Architecture

Engine (internal/crewai)

The engine provides:

• Discovery: Finds .crewai/ directories in packages
• Loading: Parses YAML configs into CrewAI objects
• Running: Executes crews with provided inputs
• CLI: crewai run <package> <crew> --input "..."

Package Crews (packages/<name>/.crewai/)

Each package can define its own crews:

packages/otterfall/.crewai/
  manifest.yaml       # Package crew configuration
  knowledge/          # Domain-specific knowledge files
  crews/
    game_builder/
      agents.yaml     # Agent definitions
      tasks.yaml      # Task definitions

CLI Usage

# From the internal/crewai directory
cd internal/crewai

# List available packages and crews
uv run python -m crew_agents list

# Run a crew
uv run python -m crew_agents run otterfall game_builder --input "Create X"

# Run with input from file
uv run python -m crew_agents run otterfall game_builder --file tasks.md

# Show crew info
uv run python -m crew_agents info otterfall game_builder

# Legacy: Direct build (uses otterfall game_builder)
uv run python -m crew_agents build "Create a QuestComponent"

Adding Crews to a Package

1. Create .crewai/manifest.yaml:

name: mypackage
description: My package crews
version: "1.0"

crews:
  builder:
    description: Build components
    agents: crews/builder/agents.yaml
    tasks: crews/builder/tasks.yaml
    knowledge:
      - knowledge/patterns

2. Create agent and task YAML files:

# crews/builder/agents.yaml
senior_engineer:
  role: Senior Engineer
  goal: Write production-quality code
  backstory: You are a senior developer...

# crews/builder/tasks.yaml
write_code:
  description: Write the requested code
  expected_output: Working code with tests
  agent: senior_engineer

3. Add knowledge files (optional):

knowledge/
  patterns/
    architecture.md
    examples.ts

GitHub Actions

The CrewAI workflow can be triggered manually:

1. Go to Actions → CrewAI Tasks
2. Select package and crew
3. Choose input type (Kiro tasks or custom)
4. Run workflow
