microsoft/power-platform-skills is a plugin marketplace containing reusable skills, agents, and commands for developing with Microsoft Power Platform. Developers use it to build and deploy Power Pages sites, model-driven Power Apps, and related solutions through Claude Code or GitHub Copilot. The catalogue entries are the marketplace's included skills, agents, plugins, and other agent components.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00034 | $0.07246 |
| Opus 5 | $0.00017 | $0.03623 |
| Sonnet 5 | $0.00007 | $0.01449 |
| Haiku 4.5 | $0.00003 | $0.00725 |
Grade A, and why
design-system 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.
How it starts
The opening of the file, as written. The whole thing — 641 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shared instructions: shared-instructions.md — read first.
Design System
Source of truth for every screen built in a Power Apps mobile app. Produces three artifacts:
brand/design-system.md— full spec (palette, typography, spacing, components, negatives)brand/tokens.ts— importable Tamagui token exportbrand/design-system.html— deterministic visual gallery (zero LLM cost)
Design-system and Tamagui integration are complementary, not alternatives. /design-system owns user-facing brand/design decisions and preview artifacts; /create-mobile-app Step 9b applies references/tamagui-integration.md as internal implementation plumbing so those decisions become Tamagui tokens, aliases, and provider props. The old separate tamagui-design-system skill existed before this split was clear; keeping it separate made users choose implementation details and added prompt surface. Do not reintroduce it as a user-invocable skill.
When to use
- Step 6.5 — auto-invoked from
/create-mobile-appafter scaffold +npx power-apps init, before screen builders - Standalone —
/design-systemcallable any time to create or refresh a brand system - Refresh —
/design-system --refresh <dimension>to change one aspect - Reskin —
/design-system --reskinfor full visual layer swap - Dark mode —
/design-system --add-dark-modeto derive + wire dark theme
When NOT to use
- Screen-level visual tweaks → use
/tweak-screen(deterministic, 0 tokens) - Plan-level screen changes → use
/edit-app screens - Data model changes → use
/add-dataverseor/setup-datamodel

What ships with it
23 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.

design-system is a skill published in the GitHub repository microsoft/power-platform-skills (829 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 7,246 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
