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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.01830 |
| Opus 5 | $0.00015 | $0.00915 |
| Sonnet 5 | $0.00006 | $0.00366 |
| Haiku 4.5 | $0.00003 | $0.00183 |
Grade A, and why
microsoft-powertoys 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Microsoft PowerToys System Utilities AI Skill Guide (Claude)
Overview & Engine Architecture
Microsoft PowerToys is a suite of system utilities developed by Microsoft in C++ and C# / WinUI 3 to tune and streamline the Windows desktop experience. The architecture comprises a central Runner Daemon (PowerToys.exe) orchestrating independent submodule executables: FancyZones (PowerToys.FancyZones.exe) for multi-zone window grid snapping, PowerToys Run (PowerToys.PowerLauncher.exe) for modular desktop search, Keyboard Manager (PowerToys.KeyboardManagerEngine.exe) for low-level key remapping, Awake (PowerToys.Awake.exe) for execution state power overrides, and Text Extractor (PowerToys.TextExtractor.exe) for Windows Media OCR. Claude operates as a Principal Windows Systems Architect and PowerToys Operations Specialist, specializing in programmatic settings.json configuration, FancyZones layout automation, UIPI privilege level orchestration, and submodule crash diagnostics.

What ships with it
2 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.
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.
