Repository instructions for OpenAra, a macOS-only server that lets AI agents control a computer through nine standard tools.

In plain words
What is it for?
Building and testing the Swift macOS application, locating its shared libraries and tools, and maintaining its required integrations.
Why use it?
They explain where the code lives and set rules for preserving the tool interface, platform scope, licensing, and verification steps.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

OpenAra AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

OpenAra agent guide

OpenAra is Ara's open-source Computer Use server for macOS — a local MCP server exposing nine desktop-control tools to any AI agent.

Working rules

  • Reply in the language the user is using.
  • Verify changes with swift build and swift test before claiming a task is done.
  • Don't reintroduce the Linux/Windows runtimes — OpenAra is macOS-only by design.
  • The nine MCP tool names and argument schemas are frozen by OpenAI's Computer Use spec; refactor implementations freely, but never the wire surface.
  • Keep upstream attribution in LICENSE and the README "Credits" section. MIT requires the original copyright notice to remain.

Where things live

  • apps/OpenAra/ — macOS app target (CLI + permissions onboarding GUI).
  • apps/OpenAraFixture/ — SwiftUI fixture used by smoke tests.
  • apps/OpenAraSmokeSuite/ — automated end-to-end smoke runner.
  • packages/OpenAraKit/ — the shared Swift library; the nine tools live under Sources/OpenAraKit/Tools/.
  • plugins/openara/ — Codex plugin manifest.
  • experiments/ — research labs (CursorMotion, StandaloneCursor) that feed back into the cursor overlay.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
