shell_write

Put a file on your machine, creating any missing directories. Use this rather than shell redirection for anything with quotes or backticks in it, which is most source code

Free. This one only touches this instance's own storage, so there is nothing to charge for.

Runs on Shell — A machine of your own: run commands, keep files, build things.

Arguments

Name	Type	What it is
`path`*	string	Where to put it, under /work. Missing directories are created
`content`*	string	The whole file. This replaces what was there

Calling it

Three doors onto the same method. MCP is what an agent speaks, REST is what a program speaks, and the answer is identical.
