AI for writing developer docs
Free prompts that rewrite a README so it runs on a clean machine, turn --help into examples, and write release notes from messy commits.
Developer docs fail in predictable places: the README never says the run command, --help lists every flag but no example, the changelog is a dump of commit subjects. Each prompt here fixes one of those from the text you already have.
Which one to use

Get clean release notes: user-facing changes, internals separated, breaking changes called out.When to use itUse it right after you tag a release, when the commits are 'fix typo', 'wip', and three real features buried in the noise.When to skip itIt writes from commit subjects. It cannot see what a vague commit actually changed, so it lists those as unclear instead of guessing.

Get three copy-paste examples, the flags that matter, and the ones that should stay hidden.When to use itUse it when your --help lists forty flags alphabetically and the one command a person needs to copy is not there.When to skip itIt does not run your CLI. It will not invent subcommands, so paste the real help output.
- 03 · Dev ToolsEasyREADME DoctorPaste a README. Get a rewrite a new contributor can follow: install, run, test, and the command that proves it worked.When to use itUse it when your README welcomes people to the project and never says the command that makes it run on a clean machine.When to skip itIt does not run your code. If your install steps are wrong, it can only flag what looks missing, not test it.
