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 | $0.00116 | $0.05365 |
| Opus 5 | $0.00058 | $0.02683 |
| Sonnet 5 | $0.00023 | $0.01073 |
| Haiku 4.5 | $0.00012 | $0.00536 |
Grade A, and why
migrate-bootstrap scanned grade A with 1 finding 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 434 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plugin check: Run

Migrate a Traditional Power Pages Site from Bootstrap 3 to Bootstrap 5
Guide the user through migrating a traditional / native Power Pages site from Bootstrap 3
to Bootstrap 5. Follow a systematic approach: verify tooling, acquire and back up the site,
assess scope, run the pac pages bootstrap-migrate engine, review the change report, apply
the residual fixes the engine can only flag, upload (which auto-enables the runtime flag),
verify, and validate.
Core Principles
- Traditional sites only: This skill targets traditional Power Pages sites (Liquid web templates,
*.webtemplate.source.html,*.html/.aspx/.ascx,*.css,sitesetting.yml). It does NOT apply to code sites (React/Vue/Angular/Astro) — they are never Bootstrap-3-based. If the target is a code site, stop and tell the user this skill doesn't apply. - The engine does the bulk; you do the residual:
pac pages bootstrap-migratedeterministically applies the well-known class renames. The skill's value is assisting with the hierarchy / CSS changes the engine only logs (see references/bootstrap-v5-manual-fixes.md). - Non-destructive, with a restore point: The engine writes a new
<folder>V5copy and never edits the source in place. Still, snapshot the source folder (git) before doing anything. - Assist and flag — never silently rewrite: Residual fixes are Liquid-aware and can break layouts. Apply them with per-category consent; when a case is ambiguous (e.g. Liquid conditionals), flag it for the user instead of guessing.
- Verify the runtime flag flip via
pac-log.txt:pac pages uploadflips the server-side Bootstrap 5 flag automatically, but flip outcomes are logged and swallowed by the CLI. Never trust the upload exit code alone. The authoritative record is the PAC diagnostic log (pac telemetry status→pac-log.txt); grep it forBootstrapV5UploadPostProcessor. The flip requires an active portal — a website record with no provisioned site logsno portal foundand skips. - Use TaskCreate/TaskUpdate: Create the todo list upfront with all 8 phases before starting work.
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.

migrate-bootstrap is a skill published in the GitHub repository microsoft/power-platform-skills (814 stars, last pushed yesterday), licensed MIT. It adds 116 tokens to every session and 5,365 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
