I implemented this hash (read and edit) approach in tilth if you want to test it out.
https://github.com/jahala/tilth
its on npm and cargo:
- cargo install tilth
- npx tilth
then tilth install claude-code/windsurf/cursor --edit
(--edit flag is needed)
I made "tilth" a few days ago, since I'm consistently trying to get the LLMs to use tools more efficiently and spend less tokens doing it -- original tilth post from Monday: https://news.ycombinator.com/item?id=46952321
You might find it useful for markdown as well, especially if you add support for section-based addressing (e.g. cat or replace a section at a time). Section-based addresses are nice because they tend to be stable across versions.
