agro 0.1.2

CLI wrapper for CLI-agents

Agro

A script to manage git worktrees for agent-based development. This tool simplifies creating, managing, and running processes within isolated worktrees, each with its own environment configuration.

Quickstart

Install with pip or uv tool:

pip install agro
uv tool install agro

Local Development Install

You can install this tool and its dependencies from the local clone of the project directory using uv:

git clone [e-mail]:sutt/agro.git"
cd agro
uv tool install . --no-cache

For local dev updates run the ./redeploy script to reinstall the local repo as agro.

0. Clone the Demo Repo

git clone [e-mail]:sutt/agro-demo.git
cd agro-demo

uv sync

Use the pre-built app + built in task in .agdocs/specs.

1. Launch two agents in parallel

• target worktrees 1 and 2.

$ agro exec 1 .agdocs/specs/add-about.md 
$ agro exec 2 .agdocs/specs/add-about.md 

Basic Output

• notice the git worktree / branch management + launch of aider

2. Launch a second agent on same task

Run command:

$ agro exec 2 .agdocs/specs/add-about.md 

• notice how work tree is incremented
• notice how API_PORT is incremented

2. Launch Server on each worktree

agro muster 'python app/main.py' 1,2 --server

• The argument --server allows detach mode to run multiple servers out of one shell.

Output

--- Running command in t1 (trees/t1) ---
$ python app/main.py > server.log 2>&1 & echo $! > server.pid

--- Running command in t2 (trees/t2) ---
$ python app/main.py > server.log 2>&1 & echo $! > server.pid

Check About Page Contents You could do this in browser as well

# check worktree app, here the /about route hasn't been created
curl http://127.0.0.1:8000/about
# {"detail":"Not Found"}

# check worktree t1
curl http://127.0.0.1:8001/about
{"message":"Keep up the great work!"}

# check worktree t2
curl http://127.0.0.1:8002/about
{"message":"This is an about page. Keep up the great work!"}

Or add your own spec to a project

For example:

Create and commit a spec file and pass to an agent

mkdir .agdocs
touch .agdocs/hello-world.md
echo "add hello world to the readme of this project" > .agdocs/hello-world.md

git add .agdocs
git commit -m "spec: hello-world"

agro exec 1 .agdocs/hello-world.md

Commands

Worktree / Agent Dispatch

• exec <index> <taskfile> ...: Run an agent in a new worktree. This command first cleans up any existing worktree for the given index, creates a fresh one, and then launches a detached agent process with the specified task file.
• muster <command> <indices>: Run a command in one or more specified worktrees. This is useful for running tests, starting servers, or executing any shell command across multiple environments.
• surrender [indices]: Kill running agent processes. If no indices are specified, it targets all running agents.

Git Helpers

• grab <branch-name>: Checkout a branch. If the branch is already in use by another worktree, it creates a copy (e.g., branch.copy) and checks out the copy.
• fade <pattern>: Delete local branches that match a given regex pattern, after a confirmation prompt.

Worktree Utility

• make <index>: Create a new worktree with a specified index. This sets up the directory, git branch, and environment.
• delete <index>: Delete the worktree and the associated git branch for a given index.

Full Help

usage: agro [-h]

A script to manage git worktrees for agent-based development.

options:
  -h, --help  show this help message and exit

Available commands:
  make <index>                  Create a new worktree.
  delete <index>                Delete the worktree with the given index.
  exec <index> <taskfile> ...   Run an agent in a new worktree.
  muster <command> <indices>    Run a command in specified worktrees (e.g., '1,2,3').
  grab <branch-name>            Checkout a branch, creating a copy if it's in use.
  fade <pattern>                Delete local branches matching a regex pattern.
  surrender [indices]           Kill running agent processes (default: all).
  help                          Show this help message.

Common options for 'make' and 'exec':
  --fresh-env         When creating a worktree, use .env.example as the base instead of .env.
  --no-env-overrides  When creating a worktree, do not add port overrides to the .env file.
  --no-all-extras     Do not install all extra dependencies when running 'uv sync'.

Options for 'muster':
  -s, --server        Run command as a background server, redirecting output and saving PID.
  -k, --kill-server   Kill the background server and clean up pid/log files.

Layout

The script creates two directories in the code repo:

• .agdocs/ - specs, configs, logs for agro
• trees/ - root for worktrees (gitignored)

- .agdocs
    - specs/
        - task1
        - task2
        ...
    - swap
        - shared logs 
        - (gitignored)
- <your-code>
    ...
- <your-configs>
    ...
- trees/
    - t1
        - <your-code>
        - <t1-configs>
    - t2
        - <your-code>
        - <t1-configs>
    ...

Worktree Configuration

agro will port .env files into the worktrees and override particular settings for parallel execution environments. And clone the env ironment (currently only supported for uv) from the main workspace into the

agro muster 'uv run which python' 1,2

--- Running command in t1 (trees/t1) ---
$ uv run which python
/home/user/tools_dev/agscript/trees/t1/.venv/bin/python

--- Running command in t2 (trees/t2) ---
$ uv run which python
/home/user/tools_dev/agscript/trees/t2/.venv/bin/python
