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.

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 | $0.00210 | $0.18543 |
| Opus 5.5 | $0.00084 | $0.07417 |
| Sonnet 5.5 | $0.00042 | $0.03709 |
| Haiku 4.5 | $0.00021 | $0.01854 |
Grade A, and why
app-builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 919 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plugin check: Run
node "${PLUGIN_ROOT}/scripts/check-version.js"— if it outputs a message, show it to the user before proceeding.
app-builder — intent → model-driven app
Turn a natural-language intent into a deployed model-driven app. You author a reviewable App Spec
(JSON) with the user across confirmed turns, then a deterministic engine (cds-maker-sdk, vendored)
builds it — tables/columns/relationships, sample data, views, Choice-column charts, adaptive forms
with sub-grids, generative pages for overview/dashboard surfaces, and the app module + sitemap.
The same spec drives create and edit: download a deployed app back into a spec, change it, and
re-run the build (it's idempotent).
CRITICAL — run the interactive flow in THIS conversation (the main loop)
You MUST run the authoring questions and the build narration yourself, in the main conversation. Do NOT dispatch a subagent (
Task) for the interactive steps.A subagent is headless —
AskUserQuestionand plan mode do not reach the user from inside one (its only output is its final message). The whole point of this skill is the multi-turn, propose-then-confirm experience, so everyAskUserQuestion,EnterPlanMode, and live build status line must originate here, in the main loop.
CRITICAL — the user sees your chat message, NOT tool output
Shell/tool output — the result of running
preview-app.js, a dry-run plan, or a lint — is COLLAPSED BY DEFAULT in the UI. The user does NOT see it unless they manually expand the tool panel. Running the command is therefore NOT the same as showing the user. Every artifact the user must read, review, or approve — the whole-app preview wireframes, the dry-run build plan, and blocking lint findings — MUST be reproduced verbatim in your chat reply, inside a fenced```code block. Never say "the preview looks right" and leave the content buried in a collapsed panel: paste it into your message. This is the #1 cause of "the wireframes aren't visible" — the preview ran, but its output stayed hidden.
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.

app-builder is a skill published in the GitHub repository microsoft/power-platform-skills (1,061 stars, last pushed yesterday), licensed MIT. It adds 210 tokens to every session and 18,543 once invoked, about $0.0008 per session on Opus 5.5. 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 2026-09-03.
