Sea of Reggio Calabria

My development setup is simple:

  • Android phone
  • Termux
  • Pi Agent
  • GitHub

No laptop. No remote desktop. Just a terminal.

Prerequisites

  • Android smartphone
  • Internet connection
  • GitHub account

1. Install Termux

Install Termux from Play store or F-Droid and open it.

Update the system:

pkg update && pkg upgrade

2. Install the required packages

pkg install git nodejs openssh termux-api

These provide:

  • git for version control
  • node and npm for Pi Agent
  • openssh for GitHub access
  • termux-api for Android integration

3. Allow storage access (Optional)

termux-setup-storage

This creates access to shared storage:

/storage/emulated/0

4. Install Pi Agent

npm install -g --ignore-scripts @earendil-works/pi-coding-agent

Verify the installation:

pi --version

5. Create the agent configuration directory

mkdir -p ~/.pi/agent

6. Create AGENTS.md

vi ~/.pi/agent/AGENTS.md

Press “I” and paste:

# Agent Environment: Termux on Android

## Environment

- OS: Android
- Terminal: Termux
- Home: `/data/data/com.termux/files/home`
- Prefix: `/data/data/com.termux/files/usr`
- Shared storage: `/storage/emulated/0`

## Open URLs

```bash
termux-open-url "https://example.com"
```

## Open Files

```bash

```

## Device Information

```

## Sharing

termux-share -a send file.txt
```

## Useful Commands

```

## Notes

- Install the Termux:API app.
- Install the `termux-api` package.
- Run `termux-setup-storage` for shared storage access.

Save and quit:

Esc
:wq

7. Start Pi Agent

pi

The first launch will guide you through the initial configuration.

8. Configure GitHub

Generate an SSH key:

ssh-keygen -t ed25519

Display the public key:

cat ~/.ssh/id_ed25519.pub

Add it to your GitHub account.

Test the connection:

ssh -T git@github.com

9. Clone a project

git clone git@github.com:username/repository.git
cd repository

10. Start coding

Launch Pi Agent:

pi

From the terminal you can:

  • edit code
  • run commands
  • create commits
  • push to GitHub
  • review pull requests
  • work entirely from your phone

Why This Setup

  • Always with me.
  • Starts in seconds.
  • Uses little battery.
  • No laptop required.
  • Works anywhere with an internet connection.

I’ve used it from:

  • the beach
  • trains
  • cafés
  • airports
  • hotel rooms

Conclusion

Modern Android phones are powerful enough for many development tasks.

With Termux, Git, and Pi Agent, a phone becomes a portable development machine.

One phone.

One terminal.

Code anywhere.
