I prompted Claude code from my phone to revive Draw!, a pixel art editor I first published 15 years ago as an exploration using Redis as a DB.

The new version is live at http://pixel.drawbang.com after 1 week of prompting Opus 4.6 with a max subscription.

Show HN: Connect a Discord channel with Claude Code agents running in tmux

I run Claude Code agents for a few personal projects on a Raspberry Pi, kept alive in tmux sessions. The missing piece was interacting with them without opening a terminal and without any additional API costs on top of my existing Pro subscription.

I created a small Discord bot that bridges a channel to the tmux session. It injects messages via tmux send-keys, posts tool call activity as progress updates, and delivers responses via a temp file.

It also forwards Claude Code's permission prompts to Discord so you can approve tool use with a 1/2/3 reply.

Claude Code's remote control works great for solo use, but I wanted an accessible way to share the agent with others, a Discord channel is a much lower bar than granting terminal access.

Limitation: one session, serial requests. Fine for low-traffic personal agents; use the API if you need concurrency.

New comment by potomak in "Gut–Brain axis"

My mother is a dietitian and she started a podcast this year where she’s talked a lot about the microbiota and how it affects our organisms in a lot of different ways.

For instance, did you know that bacteria in our guts help us “digest” and expel heavy metals?

In the third part of the episodes about the microbiota[0] she talks about the gut-brain axis:

> l’intestino può comunicare al cervello uno stato di disagio o disbiosi procurando, oltre al gonfiore, anche un possibile stato d’ansia o abbassamento dell’umore

that translates more or less to:

> the gut can communicate with the brain a dysbiotic state causing, in addition to swelling, a state of anxiety

The podcast is in Italian, but the transcriptions can be easily translated in English.

I built an app for a family member, who is a nutritionist, that makes it easier for her to stay connected with her patients via WhatsApp. It keeps track of appointments and sends automatic reminders.

Lately I decided to jump on the ChatGPT bandwagon and added a feature that integrates with the OpenAI API to suggest replies to messages from her patients.

It was overall a fun project. It gave me the chance to explore the integration with WhatsApp Business API (used to communicate with patients), OpenAI API (used to suggest message replies), Discord (used to notify events).

Apart from the APIs, it has zero dependencies. It’s deployed as a static website hosted on GitHub. The backend is written as a set of AWS Lambda functions. Data is stored in DynamoDB. Frontend is vanilla JS.
