Before deploying to CrewAI AMP, it’s crucial to verify your project is correctly structured. Both Crews and Flows can be deployed as “automations,” but they have different project structures and requirements that must be met for successful deployment.

Understanding Automations

In CrewAI AMP, automations is the umbrella term for deployable Agentic AI projects. An automation can be either:
  • A Crew: A standalone team of AI agents working together on tasks
  • A Flow: An orchestrated workflow that can combine multiple crews, direct LLM calls, and procedural logic
Understanding which type you’re deploying is essential because they have different project structures and entry points.

Crews vs Flows: Key Differences

Crew Projects

Standalone AI agent teams. New crews are JSON-first with crew.jsonc and agents/; classic crews can still use crew.py.

Flow Projects

Orchestrated workflows with embedded crews in a crews/ folder. Best for complex, multi-stage processes.
AspectCrewFlow
Project structureProject root with crew.jsonc and agents/src/project_name/ with crews/ folder
Main logic locationcrew.jsonc (classic: src/project_name/crew.py)src/project_name/main.py (Flow class)
Entry point functionLoaded from crew.jsonc (classic: run() in main.py)kickoff() in main.py
pyproject.toml typetype = "crew"type = "flow"
CLI create commandcrewai create crew namecrewai create flow name
Config locationcrew.jsonc, agents/, optional tools/src/project_name/crews/crew_name/config/ or embedded JSON crew folders
Can contain other crewsNoYes (in crews/ folder)

Project Structure Reference

Crew Project Structure

When you run crewai create crew my_crew, you get the JSON-first structure:
my_crew/
├── .gitignore
├── pyproject.toml          # Must have type = "crew"
├── README.md
├── .env
├── uv.lock                  # REQUIRED for deployment
├── crew.jsonc               # Crew settings, tasks, process, inputs
├── agents/
│   └── researcher.jsonc     # Agent definitions
├── tools/                   # Optional custom:<name> tools
├── knowledge/
└── skills/
For JSON-first crews, keep crew.jsonc, agents/, tools/, knowledge/, and skills/ at the project root. Placing them under src/ will prevent crewai run and deployment validation from finding the crew definition.
Classic projects created with crewai create crew my_crew --classic use the older src/project_name/crew.py, src/project_name/config/agents.yaml, and src/project_name/config/tasks.yaml layout. That layout remains supported for decorator-based Python crews.

Flow Project Structure

When you run crewai create flow my_flow, you get this structure:
my_flow/
├── .gitignore
├── pyproject.toml          # Must have type = "flow"
├── README.md
├── .env
├── uv.lock                  # REQUIRED for deployment
└── src/
    └── my_flow/
        ├── __init__.py
        ├── main.py          # Entry point with kickoff() function + Flow class
        ├── crews/           # Embedded crews folder
        │   └── poem_crew/
        │       ├── __init__.py
        │       ├── poem_crew.py  # Crew with @CrewBase decorator
        │       └── config/
        │           ├── agents.yaml
        │           └── tasks.yaml
        └── tools/
            ├── __init__.py
            └── custom_tool.py
JSON-first standalone crews use project-root JSON files. Flows still use src/project_name/ and can contain either classic embedded crews or embedded JSON crew folders loaded with crewai.project.load_crew.

Pre-Deployment Checklist

Use this checklist to verify your project is ready for deployment.

1. Verify pyproject.toml Configuration

Your pyproject.toml must include the correct [tool.crewai] section:
[tool.crewai]
type = "crew"
If the type doesn’t match your project structure, the build will fail or the automation won’t run correctly.

2. Ensure uv.lock File Exists

CrewAI uses uv for dependency management. The uv.lock file ensures reproducible builds and is required for deployment.
# Generate or update the lock file
uv lock

# Verify it exists
ls -la uv.lock
If the file doesn’t exist, run uv lock and commit it to your repository:
uv lock
git add uv.lock
git commit -m "Add uv.lock for deployment"
git push

3. Validate the Crew Definition

JSON-first crews must have a crew.jsonc or crew.json file at the project root. The agents array must reference files in agents/, and each task should reference a valid agent name.
crew.jsonc
{
  "name": "Research Crew",
  "agents": ["researcher"],
  "tasks": [
    {
      "name": "research_task",
      "description": "Research {topic}.",
      "expected_output": "A concise report.",
      "agent": "researcher"
    }
  ],
  "inputs": {
    "topic": "AI Agents"
  }
}
Custom tools are referenced as "custom:<name>" and must be implemented in tools/<name>.py with a BaseTool subclass.

4. Check Project Entry Points

JSON-first standalone crews do not need a hand-written src/project_name/main.py; crewai run and deployment packaging load crew.jsonc directly. Classic crews and Flows use Python entry points:
Run locally from the project root:
crewai run

5. Prepare Environment Variables

Before deployment, ensure you have:
  1. LLM API keys ready (OpenAI, Anthropic, Google, etc.)
  2. Tool API keys if using external tools (Serper, etc.)
If your project depends on packages from a private PyPI registry, you’ll also need to configure registry authentication credentials as environment variables. See the Private Package Registries guide for details.
Test your project locally with the same environment variables before deploying to catch configuration issues early.

Quick Validation Commands

Run these commands from your project root to quickly verify your setup:
# 1. Check project type in pyproject.toml
grep -A2 "\[tool.crewai\]" pyproject.toml

# 2. Verify uv.lock exists
ls -la uv.lock || echo "ERROR: uv.lock missing! Run 'uv lock'"

# 3. For JSON-first crews, verify crew.jsonc and agents/ exist
([ -f crew.jsonc ] || [ -f crew.json ]) || echo "No crew.jsonc or crew.json found"
test -d agents || echo "No agents/ directory found"

# 4. For classic Crews - verify crew.py exists
ls -la src/*/crew.py 2>/dev/null || echo "No crew.py (expected for Crews)"

# 5. For Flows - verify crews/ folder exists
ls -la src/*/crews/ 2>/dev/null || echo "No crews/ folder (expected for Flows)"

# 6. For classic Python crews - check for CrewBase usage
grep -r "@CrewBase" . --include="*.py"

Common Setup Mistakes

MistakeSymptomFix
Missing uv.lockBuild fails during dependency resolutionRun uv lock and commit
Wrong type in pyproject.tomlBuild succeeds but runtime failsChange to correct type
Missing crew.jsonc or agents/ in a JSON-first crewCrew definition not foundKeep crew.jsonc and agents/ at the project root
Missing @CrewBase decorator in a classic crew”Config not found” errorsAdd decorator to all classic crew classes
Classic files at root instead of src/Entry point not foundMove classic Python files to src/project_name/
Missing run() or kickoff()Cannot start automationAdd correct entry function

Next Steps

Once your project passes all checklist items, you’re ready to deploy:
