A dozen coding agents running in parallel, producing walls of suggestions, comments and ideas, all at once, all crammed into 88 columns of terminal scrollback, all gone the moment you run the next command. Does this sound familiar?
FolderMd might be for you. It's free, and it's fast, and your agents can use it. I made it because I just couldn't handle it anymore.
It's a small Mac app that gives those documents a home. Agents read our explainer and then learn to write markdown into a .foldermd/, instead of writing it into the terminal. FolderMD then opens each one instantly and renders it like a book: real typography, syntax-highlighted code, Mermaid diagrams, light and dark mode.
You can edit a doc and save it, you can then add comments just like you would in Google Doc, and pass those comments to the agent.
Setup is one click. It installs a small foldermd CLI and adds routing rules to CLAUDE.md, AGENTS.md, .cursorrules and the like, so your agents start using it without being reminded. The files are plain markdown on disk. There are no accounts and no telemetry.
It's also free (macOS 13+, Apple silicon and Intel).
p.s. I'm curious how others deal with long agent output. Do you read it in the terminal, pipe it somewhere, or just skim and hope? Feedback on the workflow is very welcome.
