Roll your own coding agent with 100 lines

The idea is simple. Write the bare minimal harness by hand and then ask it to write itself.

blog post about this

bun install

Create a .env with:

OPENAI_API_KEY=... # required
OPENAI_MODEL=... # required
OPENAI_BASE_URL=... # optional, defaults to OpenAI's official endpoint

It starts with the bare minimal. Only non-interactive mode(-p) is implemented

bun start -- -p "review this project and add 3 jokes to README.md"

Ask it to write itself

bun start -- -c -p "implement interactive mode for this project" # -c to continue from the last session

Get some eyecandy

bun start -- -c -p "make this project look nicer"

Ask your 100cc to implement TODO.md

Have fun and share with your friends!
