usecomputer: Instructions file for Codex

AGENTS.md

usecomputer AGENTS.md is an instructions file for Codex, OpenCode from remorses/usecomputer. It costs 2,433 tokens per session, scanned A, original, MIT.

Repository instructions for building usecomputer, a macOS desktop automation command-line tool for AI agents. They describe its mouse, keyboard, screenshot, clipboard and window commands, plus the native code and reference behavior they should follow.

In plain words
What is it for?
Implementing or updating usecomputer commands, native Zig and macOS API integrations, N-API bindings, and cross-platform input backends.
Why use it?
They give coding agents a shared source of truth for command behavior and edge cases. This reduces guesswork when changing the tool or keeping its macOS behavior consistent across platforms.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is remorses/usecomputer's own configuration. It tells Codex and OpenCode how to work on usecomputer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything usecomputer configures →

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

usecomputer 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 1mo 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.

usecomputer agent notes

Goal

usecomputer is a macOS desktop automation CLI for AI agents. The package should expose stable, scriptable computer-use commands (mouse, keyboard, screenshot, clipboard, window actions) backed by a native Zig N-API module, with behavior aligned to CUA command semantics.

Source of truth for command behavior

CUA references are the primary behavioral source of truth for command semantics and edge cases. When implementing or adjusting command behavior, always compare against these files first:

Implementation note: this package does not use pyobjc. We implement the same command behavior using Zig + native macOS APIs.

Native implementation dependencies

Cross-platform input backend reference

For mouse/keyboard parity across macOS, Windows, and Linux, use pynput as a behavior and backend reference (do not copy code directly; keep implementation native in Zig):

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.
