A coding agent in 306 lines of Python, as a teaching example

What the research found

A tutorial builds a 306-line Python coding agent with requests as its only dependency, nine tools and any OpenAI-compatible API, explicitly labeled a teaching example and not for production.

Claims and how well the evidence supports them

1. 306 lines of Python, requests as the one required dependency 98%
2. Nine tools including read_file, edit_file, grep and bash 99%
3. Works with any OpenAI-compatible /v1/chat/completions provider 97%
4. bash runs model-requested commands; only a y/N prompt guards it, disabled by --yes 98%
