What is it

ostk is an operating system for AI agents. It replaces Jira, Slack, GitHub workflows, CI, and your IDE with a single Rust binary that coordinates agents through the filesystem. Agents run on it without knowing — byte-for-byte passthrough for every command, with conflict resolution and coordination underneath.

How it works

  1. Install. curl -fsSL https://ostk.ai/install | sh — boots the OS on any git repo.
  2. Work. Your agents use their normal tools. The OS intercepts writes, resolves conflicts, compresses output, and tracks everything. Nothing changes for the agent.
  3. Speak tack. You type intent in shorthand. The OS compiles it into agent actions. :compile :plan :ship — three words, full execution.

Why it exists

Agent frameworks ask agents to learn new APIs. That's backwards. An OS doesn't ask processes to coordinate — it provides the primitives and stays out of the way.

ostk emerged from building itself. 104 commits, 698 tests, 539 needles — all managed by agents running on the OS that was being built. No meetings. No standups. No Jira tickets. The evidence is the product.

Five laws govern everything:

  1. The write path is invisible
  2. Agents are ephemeral
  3. Coordinate through the filesystem
  4. Optimistic concurrency
  5. Invisible infrastructure, always

Get started

curl -fsSL https://ostk.ai/install | sh
cd your-repo
haystack boot

The OS is running. Your agents are already on it.
