What it does
Cua Driver is an agent skill from bastani-inc/atomic. Drive a native GUI app (macOS, Windows, Linux) via the cua-driver CLI (default) or MCP server; snapshot its accessibility tree, act through snapshot-bound element tokens, native menu paths, exact window geometry, or pixel coordinates, and verify from fresh state. Use when the user asks you to operate, drive, automate, or perform a GUI task in a real application on the host, or to continue, resume, or recall recent Cua activity.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files (for example `BROWSER.md`, `EMBEDDING.md` and `LINUX.md`).
It sits in Frontend & Design. It works with Linux, Model Context Protocol and macOS. The repository describes itself as: The verifiable coding agent runtime. Define your coding agent's process in natural language with stages, checks, and approval gates instead of hoping it follows your…
When your agent uses it
- The user asks you to operate
- Perform a GUI task in a real application on the host
- Recall recent Cua activity
Example prompts
- “/cua-driver”
Requirements
- Pre-approved tools (allowed-tools): Bash(cua-driver:*)
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Select the exact target on each action. A session is lifecycle metadata, not capture scope or permission authority.
- Observe before input and verify after it. effect:"unverifiable" and a successful exit are not task success; never replay a partial…
- Use returned tokens, never invented indices. A fresh snapshot replaces prior element handles and lists them in invalidated_snapshot_ids…
- Keep background window actions non-interfering. Foreground delivery and desktop input require authorization for visible control; an…
- Never infer pixels from a missing image, a different window, or an unaccounted-for resized preview. Capture failure and an empty…
- Keep one controller for a shared desktop. Distinct sessions/cursors do not isolate focus, keyboard input, application state, or snapshot…
- User/system permission prompts belong to the user or trusted host. Never alter browser profiles or security settings as hidden setup…
What it can do on your machine
Read from SKILL.md and the folder at commit 23dbfd7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(cua-driver:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cua Driver loads about 2k tokens when it runs. Until then it costs about 111 tokens; SKILL.md has 691 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 691 words (~2,040 tokens).
“Operate one exact target, observe its state, act once, and verify the user's postcondition.”

Cua Driver is an agent skill from bastani-inc/atomic. Drive a native GUI app (macOS, Windows, Linux) via the cua-driver CLI (default) or MCP server; snapshot its accessibility tree, act through snapshot-bound element tokens, native menu paths, exact window geometry, or pixel coordinates, and verify from fresh state.
When should I use Cua Driver?
Cua Driver fits situations like: the user asks you to operate; perform a GUI task in a real application on the host; recall recent Cua activity.
How do I install Cua Driver in Claude Code?
Run `npx skills add bastani-inc/atomic --skill cua-driver -a claude-code`. Or copy the skill folder (packages/subagents/skills/cua-driver in bastani-inc/atomic) into .claude/skills/cua-driver in your project. Claude Code loads it when a task matches its description.
How do I install Cua Driver in Codex?
Run `npx skills add bastani-inc/atomic --skill cua-driver -a codex`. Or copy the skill folder (packages/subagents/skills/cua-driver in bastani-inc/atomic) into .agents/skills/cua-driver in your project. Codex loads it when a task matches its description.
Can I use Cua Driver in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add bastani-inc/atomic --skill cua-driver -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cua-driver, .gemini/skills/cua-driver, .github/skills/cua-driver and .opencode/skills/cua-driver in your project.
What does Cua Driver need to run?
SKILL.md names no scripts, command-line tools or credentials: Cua Driver is instructions for the agent only. Its frontmatter pre-approves these tools: Bash(cua-driver:*).
Does Cua Driver access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Cua Driver safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Cua Driver use?
Cua Driver has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Cua Driver use?
About 2k tokens (SKILL.md is roughly 8.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Cua Driver?
Skills that share tags, products or a category with Cua Driver: Gearcoleco Debugging (drhelius/Gearcoleco, 142 stars), Jarvis Setup (ethanplusai/jarvis, 846 stars), Cortex Mem MCP (sopaco/cortex-mem, 313 stars) and Mps Project Management (JetBrains/MPS, 1.7k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
