This comment belongs in a discussion about using LLMs to help write code for large existing systems - it's a bit out of place in a discussion about a tutorial on building coding agents to help people understand how the basic tools-in-a-loop pattern works.

anyone who used those coding agent can already see how it works, you can usually see agent fetching files, running commands, listing files and directories.

i just wrote this comment so people aren't under false belief that it's pretty much all coding agents do, making all this fault tolerant with good ux is lot of work.
