Read What Claude Code Writes

CLAUDE.md, AGENTS.md, plans and READMEs, rendered in Finder and live as they change

Coding agents work in Markdown. Claude Code reads a CLAUDE.md for instructions, other agents an AGENTS.md, and they write plans, notes and READMEs as they go. Those files are meant to be read, and Quick Look shows them as plain text. spacebar renders them when you press Space.

Watch A Plan As It’s Written

Leave the preview open while the agent works. It redraws each time the file is saved and keeps your place, so a long plan stays readable while it grows.

Tick And Fix In Place

Tick a task in a checklist and it’s written to the file. Click a paragraph to correct an instruction in CLAUDE.md and it saves. If the agent changed the file in the meantime, its change wins and your edit is dropped, so the agent’s work is never overwritten.

The Folder In The Sidebar

The sidebar shows the file’s folder as a tree. A click shows any file in the panel: other Markdown, code highlighted with line numbers, pretty-printed JSON, CSV as a table, images and PDFs. Links to other Markdown files open in the same panel, so a plan that points to an architecture.md beside it is one click away.

Folders that start with a dot, such as .claude, stay hidden unless you turn on Show hidden files. In Finder, ⌘ ⇧ . shows them too.

Safe For Untrusted Files

Documents are sanitised and can’t run scripts, and remote images are off by default, so nothing in a file an agent pulled from elsewhere runs when you look at it.
