Project Log #20: After Hours of Screen Time, the Agent Has a Face

#python #ai #webdev #automation

Day 20. I stared at my screen until my eyes burned. But the web interface is live. Flask backend connected. The agent is finally usable.

I've been staring at this screen for hours.

Not the productive kind of staring. The frustrating kind. The kind where you write 50 lines of code, test it, watch it break, rewrite it, test it again, and repeat until you forget what time it is.

Today was that kind of day.

What Got Built

After hours of debugging, I shipped two things:

A Flask server (server.py) that wraps the agent in a REST API. Three endpoints: /status checks if Ollama and ADB are connected. /command sends a natural language command to the agent and returns the result. /history returns the last 20 commands.
A web interface (interface.html) that looks like a chat app. Dark terminal theme. Gold accents. Type a command. See the agent respond. Real-time status indicators showing whether Ollama and ADB are alive.

The interface talks to Flask on localhost:5000. Flask talks to the agent. The agent talks to the phone. Everything local. No cloud. No external servers. Just a phone running its own AI.

The Grind

Here's what the polished build log doesn't show:

Flask refused to serve the HTML file for 45 minutes because I forgot send_file needs an absolute path.
The status endpoint kept returning false for ADB because I was checking the wrong string in the output.
The interface looked like a developer's debug page until the third redesign.
CORS errors because I forgot flask-cors. Ten minutes of confusion for a one-line fix.
The send button wasn't working because I misspelled getElementById. Thirty minutes. One missing character.

This is the real build log. Not the clean version. The "I need to step away from this screen before I throw my phone" version.

The Result

The interface works. It's not beautiful yet. The design will evolve. But you can type a command in a browser, hit enter, and watch the agent execute it on the phone. That's the milestone.

Status bar at the top. Chat display in the middle. Input area at the bottom. Example commands you can click. Loading states. Error messages. All the basics.

What Still Needs Work

The setup process is still manual. Install Termux. Pull Ollama. Configure ADB. Run the server. Open the browser. Too many steps. A setup script is next.
The interface needs polish. Animations are basic. The design is functional but not premium. I'll iterate.
End-to-end testing hasn't happened yet. The agent works in controlled tests. Real-world reliability is the next frontier.
