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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 7 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.01816 |
| Opus 5 | $0.00023 | $0.00908 |
| Sonnet 5 | $0.00009 | $0.00363 |
| Haiku 4.5 | $0.00005 | $0.00182 |
Grade A, and why
add-pdf-viewer 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 5d 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.

Add PDF Viewer
Internal helper. Users should invoke /add-native pdf-viewer, /add-native pdf-control, or /add-native @microsoft/power-apps-native-pdf-viewer; /add-native routes here after resolving the capability.
Generate or verify the native PDF viewer wrapper and show how to call its native React Native API. Version 0.2.9 and later support HTTPS PDF URLs and local file:// URIs. Do not use the HostingSDK / PCF path from the package README; that is for a different use case.
Steps
1. Verify app
test -f app.config.js && test -f power.config.json && test -f package.json && test -d src
If this fails, tell the user to run /create-mobile-app first and STOP.
2. Verify package is already present
node -e "const p=require('./package.json'); const m='@microsoft/power-apps-native-pdf-viewer'; if (!p.dependencies?.[m]) { console.error('MISSING: ' + m + ' is not in package.json. The template/app must already ship this native extension. This skill will not install it or edit native config.'); process.exit(1); } let v; try { v=require('./node_modules/' + m + '/package.json').version; } catch { console.error('MISSING_INSTALL: cannot verify the installed ' + m + ' version. Run the project package install first.'); process.exit(1); } const [major,minor,patch]=v.split('.').map(Number); if (!(major > 0 || minor > 2 || (minor === 2 && patch >= 9))) { console.error('UNSUPPORTED_VERSION: ' + m + ' ' + v + ' does not support file:// URIs. Version 0.2.9+ is required.'); process.exit(1); } console.log('OK: native PDF viewer ' + v + ' supports https:// and file://');"
If the check fails, STOP. Do not run npm install, npx expo install, pod install, or edit app.config.js. Version 0.2.9+ must already be part of the app's native build.
3. Write or verify src/native/pdfViewer.ts
Create src/native/pdfViewer.ts if it does not exist. If it already exists, inspect it and patch only if it violates the supported URI rules or throws instead of returning a result.
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.

add-pdf-viewer is a skill published in the GitHub repository microsoft/power-platform-skills (844 stars, last pushed today), licensed MIT. It adds 47 tokens to every session and 1,816 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.
