Usage and Workflow

Running DevTeam CLI

To utilize DevTeam CLI, navigate to the directory where your git projects are stored. For example:

cd ~/projects
devteam

If you have specific directories you want to point DevTeam CLI to, you can specify them explicitly:

devteam --dir /path/to/your/projects

Or set the PROJECTS_DIR environment variable:

export PROJECTS_DIR=/path/to/your/projects
devteam

Best Practices for Optimal Performance

To get the best results from DevTeam CLI, consider these best practices:

• Use a Virtual Machine: Run DevTeam CLI in a virtual machine and provide your agents with broad permissions within this sandboxed environment. This ensures isolation and security.
• Dedicated GitHub Account: Assign a dedicated GitHub account that the agents can use to create PRs automatically. This streamlines the workflow and ensures accountability.
• Set Guidelines: Add guidelines in CLAUDE.md or AGENTS.md files to ensure each feature includes tests and is submitted as a separate PR. This helps maintain code quality and organization.

Key Features of DevTeam CLI

DevTeam CLI is equipped with several features designed to enhance your development workflow:

• Parallel Agent Operation: Kick off multiple agents working on different features simultaneously using git worktrees. This parallel processing capability significantly speeds up development cycles.
• Built-in Differ Viewer: See their code changes with an integrated diff viewer, allowing you to review changes in real time and add comments directly.
• Highlighted Requests: Agents that require your input are highlighted in the UI, making it easy to prioritize and address them promptly.
• Project Status Overview: Track the progress of each agent through diff line counts, whether the feature is pushed, GitHub PR checks, and status updates.
• Local Testing: Run your program or server in each worktree easily to test the changes made by the agents. This quick feedback loop helps in refining the code immediately.
• Flexible Agent Choice: Choose from Claude Code, Codex, or Gemini CLI to work on each feature, depending on your specific needs and preferences.

Project Management with DevTeam CLI

DevTeam CLI is not just about running multiple agents; it’s about efficiently managing their outputs and integrating them into your project workflow. Here’s how you can effectively manage your projects:

Starting Multiple Agents

To begin working with multiple agents, simply open DevTeam CLI and let it generate new agents for your projects:

devteam new-agent --type claude-code --name "Agent-01"

You can start multiple agents and monitor their activities side-by-side, providing a comprehensive view of the development progress.

Reviewing Changes and Adding Comments

As agents generate code and make changes, DevTeam CLI provides a built-in diff viewer that highlights all changes:

devteam diff --agent Agent-01

You can add comments directly to the changes, which will be sent back to the respective agent for immediate attention. This real-time feedback mechanism ensures that issues are resolved quickly and efficiently.

Automated Pull Requests

One of the standout features of DevTeam CLI is its ability to automate pull requests. Once satisfied with the changes made by an agent, you can create a PR with a single command:

devteam pr --agent Agent-01 --branch feature/new-feature

This command creates a pull request for the specified agent’s branch, making it easy to integrate changes into the main project.

Monitoring Progress and Status

The DevTeam CLI provides a detailed overview of each agent’s progress, including:

• Diff Line Counts: How many lines have changed compared to the last commit.
• PR Checks: The status of automated checks on the pull request.
• GitHub PR Status: Whether the pull request has been approved or rejected.
  These insights help you keep track of where each agent stands and what needs your attention next.

Advanced Configurations and Customizations

For users looking to tailor DevTeam CLI to their specific needs, several advanced configuration options are available:

Customizing Agent Behavior

You can customize various aspects of how agents behave by editing the configuration file located at ~/.config/devteam/config.json. For example, you might want to limit the number of changes an agent can make in one session or adjust the frequency of updates:

{
  "max_changes": 500,
  "update_frequency": "10s"
}

These settings ensure that agents operate within defined boundaries, preventing excessive changes and maintaining code stability.

Security Considerations

When working with multiple agents, especially in shared environments, ensuring security is crucial. DevTeam CLI supports configuring access controls to restrict what agents can modify:

allowed_paths: ["src/**", "test/**"]
disallowed_files: ["README.md", "package.json"]

By specifying allowed paths and disallowed files, you can prevent agents from making unintended changes to critical parts of your project.

Logging and Debugging

For troubleshooting and monitoring purposes, DevTeam CLI provides detailed logging capabilities:

devteam logs --agent Agent-01

This command outputs logs generated by the specified agent, helping diagnose any issues that may arise during development. Additionally, you can enable more verbose logging for deeper insights:

devteam logs --agent Agent-01 --verbose
