Pathrule

macOS app

Pathrule Studio, native on your Mac.

The desktop workspace where your agents, tasks and designs work from the same understanding of your product. This page is about the app itself: what ships inside it, how the first run goes, and what it needs from your Mac.

One window, the whole workbench.

Studio is not a chat window with panels bolted on. The things you reach for while building sit in the same app, around the conversation.

The runtime comes with the app.

No separate service to install and no MCP wiring to maintain. This is what happens between opening a thread and the agent acting.

  1. 01

    You open a thread

    In a directory the workspace is attached to, so the runtime knows which path the work is on.

  2. 02

    The hook supervisor reads the cache

    A precomputed index of the memories, rules and skills pinned at that path and the ones above it.

  3. 03

    The engine starts already knowing

    The slice is in context before the first tool call, with no round trip to fetch it.

Studio also bundles the MCP server your assistant speaks to, companion file sync for CLAUDE.md and AGENTS.md, and schedules that wake it up on their own.

Where to go deeper.

What you can actually build with Studio is laid out capability by capability on the features page. These are the parts of the app itself.
