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.

SkillSpector: 2 findings, up to high
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 →
- high Prompt Injection · line 97 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
- medium Excessive Agency · line 16 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 | $0.00120 | $0.04017 |
| Opus 5 | $0.00060 | $0.02008 |
| Sonnet 5 | $0.00024 | $0.00803 |
| Haiku 4.5 | $0.00012 | $0.00402 |
Grade A, and why
security-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 309 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plugin check: Run
node "${PLUGIN_ROOT}/scripts/check-version.js"— if it outputs a message, show it to the user before proceeding.
Review Security
Guide the user through a full security review of their Power Pages site. Runs the matching focused skills and assembles every finding into a single HTML report.
The skill never asks the user technical questions. The conversation stays in plain language.
Initial request: $ARGUMENTS
Workflow
The skill has six phases. Phases 2–5 each map to one conversation beat with the user; phases 1 and 6 are silent setup and cleanup. See references/flow.md for the rationale behind each beat.
| Phase | What happens | User-facing beat |
|---|---|---|
| 1 — Prerequisites | Locate project, set up working folders | (silent setup) |
| 2 — Scope | Capture goal — one question, three answers, plain language | Ask the goal |
| 3 — Skills | Run the matching skills, surface progress | Scan in progress |
| 4 — Report | Build the consolidated report — totals + per-section findings | Results summary + Findings |
| 5 — Present | Present results, offer remediation follow-ups | Next steps and guidance |
| 6 — Cleanup | Remove temporary files | (silent cleanup) |
Task Tracking
Create tasks in three groups. Mark each in_progress when starting, completed when done.
Group 1 — create at the start of prerequisites:
| Task subject | activeForm |
|---|---|
| Check prerequisites | Checking prerequisites |
Only this one task. Do not create any other tasks until prerequisites complete.
Group 2 — create after prerequisites complete:
| Task subject | activeForm |
|---|---|
| Capture goal | Capturing goal |
Group 3 — create after the goal is captured:
| Task subject | activeForm |
|---|---|
| Run skills | Running checks |
| Build the report | Building the report |
| Present findings | Presenting findings |
| Clean up | Cleaning up |
What ships with it
1 file 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.

security-review is a skill published in the GitHub repository microsoft/power-platform-skills (836 stars, last pushed today), licensed MIT. It adds 120 tokens to every session and 4,017 once invoked, about $0.0006 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 2026-09-03.
