platynui

platynui is a skill for Claude Code, Codex from manykarim/robotframework-agentskills. It costs 85 tokens per session (3,189 once invoked), scanned A, original, Apache-2.0.

A guide for writing Robot Framework tests that automate native desktop apps on Windows and Linux through their accessibility interfaces.

In plain words
What is it for?
It helps automate desktop interactions and find controls with XPath-style selectors using PlatynUI.BareMetal.
Why use it?
It gives agents one query style for locating windows, buttons, menus, and text fields across supported desktop systems, while documenting that the library is pre-release.

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

platynui 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 4d 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.

PlatynUI Library Skill (new_core / BareMetal)

Quick Reference

PlatynUI is cross-platform native desktop UI automation for Robot Framework. It normalizes Windows UIA, Linux AT-SPI2 (and planned macOS AX) into one desktop UI model that you query with XPath-2.0-style selectors.

⚠️ Preview / pre-release. This skill targets the new_core rewrite. The only usable keyword library today is PlatynUI.BareMetal; the high-level PlatynUI library is a not-yet-implemented placeholder. Keywords, CLI output, and behavior may change.

Installation

Get the version with the right pin — this is the #1 mistake:

# ✅ new_core (PlatynUI.BareMetal, documented keywords) — pin OR use --pre:
pip install robotframework-PlatynUI==0.12.0.dev330
pip install --pre robotframework-PlatynUI          # latest pre-release

# ❌ WRONG — installs old 0.9.2 (a different library, NO BareMetal):
pip install robotframework-PlatynUI                # no --pre, no pin → 0.9.2
  • A plain pip install robotframework-PlatynUI resolves the old stable 0.9.2, whose surface is a different, near-undocumented PlatynUI library with no BareMetal. You only get new_core by opting into the pre-release (--pre) or pinning an exact dev version.
  • The wheel is prebuilt — it bundles the compiled platynui-native runtime (_native.abi3.so). No Rust toolchain and no git checkout required. Python 3.12+ only.
  • Optional CLI / inspector tools (for locator development — see below):
    uv tool install --prerelease allow platynui-cli
    uv tool install --prerelease allow platynui-inspector
    
  • Linux additionally needs a running AT-SPI2 accessibility bus and (recommended) an X11 session — see references/platform-setup.md.

Library Import

*** Settings ***
Library    PlatynUI.BareMetal

Import arguments (all keyword-only, all optional):

Argument Default Purpose
auto_activate True Bring the target element's window to the foreground before pointer/keyboard actions. Override per-call with activate=.
use_mock False Use the Rust mock provider (deterministic, no desktop). Note: the published wheel is built without mock support and raises ProviderError; needs a --features mock-provider source build.
keyboard_profile / pointer_profile / pointer_settings None Tune input timing/motion realism. Accept a native object or a plain &{dict} (e.g. press_delay_ms, acceleration_profile, motion).

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
