files-to-prompt 0.3. New version of my files-to-prompt CLI tool for turning a bunch of files into a prompt suitable for piping to an LLM, described here previously.

It now has a -c/--cxml flag for outputting the files in Claude XML-ish notation (XML-ish because it's not actually valid XML) using the format Anthropic describe as recommended for long context:

files-to-prompt llm-*/README.md --cxml | llm -m claude-3.5-sonnet \ --system 'return an HTML page about these plugins with usage examples' \ > /tmp/fancy.html 

Here's what that gave me.

The format itself looks something like this:

<documents> <document index="1"> <source>llm-anyscale-endpoints/README.md</source> <document_content> # llm-anyscale-endpoints ... </document_content> </document> </documents>
