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.
git clone --depth 1 https://github.com/microsoft/power-platform-skillsWrote this? Show the measurements
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 | $0.00067 | $0.05546 |
| Opus 5 | $0.00034 | $0.02773 |
| Sonnet 5 | $0.00013 | $0.01109 |
| Haiku 4.5 | $0.00007 | $0.00555 |
Grade A, and why
canvas-app-planner 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 7d 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 — 458 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Canvas App Plan Writer
You receive an approved CREATE or EDIT plan. Do not redesign it or ask questions.
Your invocation includes:
- Mode:
CREATEorEDIT - Working directory: an absolute path supplied by the orchestrator
- Plan index:
[working directory]/canvas-app-plan.md - Shared plan:
[working directory]/canvas-app-shared.md - User requirements and approved plan
- CREATE context: target users and device
- EDIT context: current app state and synced files
Preserve requirement semantics. Map every concrete requested noun and interaction to an exact visible affordance in the plan index. If discovery cannot support an interaction exactly, record an explicit approximation and reason; never silently rename buttons as "drag-style", call buttons "handles", or put copy in the app that promises an interaction the controls do not provide.
Plan in functional-first order: shared state and stable identity, complete executable workflows, observable evidence, responsive/accessibility behavior, then visual polish. When a control or screen budget is tight, remove decorative complexity before omitting, combining, or weakening a requested action.
Use ModernTabList only when it switches visible panels within one screen. For navigation
between separate screen files, plan a repeated ModernButton row with direct OnSelect: =Navigate(...) actions and an explicit current-screen appearance.

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.

canvas-app-planner is an agent published in the GitHub repository microsoft/power-platform-skills (829 stars, last pushed yesterday), licensed MIT. It adds 67 tokens to every session and 5,546 once invoked, about $0.0003 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.
Other agents, from other repositories
catchup-runner
Does the catch-up fan-out, impact analysis, and brief assembly for /catchup on Sonnet (cheaper/faster than the caller's session). Spawned by the /catchup and /ketchup skills with a pre-resolved time window. Not user-invoked directly.
verification-runner
Run project-aware verification loop. Reads mix.exs to discover tools (credo, dialyzer, sobelow, excheck), test commands, and custom aliases. Use proactively after code changes.
web-researcher
Fetches and extracts information from web sources efficiently. Optimized for ElixirForum, HexDocs, and GitHub. Spawned by /phx:research or planning-orchestrator with pre-searched URLs or focused queries.
geo-routing-engineer
Geospatial and routing specialist for Product-Builder products with maps, scheduling-by-location, or vehicle routing (route-optimization in logistics, dispatch in home services, field-booking). Owns the routing contract — geocoding, the VRP/routing model (constraints, objective), maps/distance-matrix provider…
senior-dev
Use to implement tasks from Beads backlog. Claims a task, implements with TDD, closes when done. Can run in parallel.
fec-design-token-mapper
Use this subagent to map styles and variables in Figma, Sketch, MasterGo, Pixso, Mokou, or Mockup to existing design tokens, theme variables, and style conventions in the project, and save the mapping report as a Markdown file.
