Recently, I came across a post on Hacker News titled “Executable Markdown files with Unix pipes”. I couldn't help but think, "This is interesting."

By using claude-switcher, you can make a Markdown file executable simply by writing #!/usr/bin/env claude-run at the top of the file. Furthermore, it can be piped together just like any ordinary Unix command.

The idea of "integrating LLMs into a pipeline" is refreshing, and I was eager to try it out.

claude-switcher is a tool that makes Markdown files executable on Claude Code. It was developed by the team at Andi Search and is released under the MIT license.

The essence of this tool lies in the "combination of deterministic processing and LLMs."

Tasks that were difficult to handle with traditional shell scripts can now be accomplished, such as:

These "ambiguous tasks that required human judgment" can now be delegated to LLMs. Moreover, they can be treated as part of a pipeline.

The novelty is in connecting deterministic processing (shell scripts, command lines) with non-deterministic processing (LLMs) in the same pipeline.
