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: 1 finding, 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 →

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 | $0.00079 | $0.10868 |
| Opus 5.5 | $0.00032 | $0.04347 |
| Sonnet 5.5 | $0.00016 | $0.02174 |
| Haiku 4.5 | $0.00008 | $0.01087 |
Grade A, and why
powerapps-canvas-yaml-generator 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 1mo 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 — 1,137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Power Apps Canvas App YAML Generator
Generates production-ready Power Apps Source Code YAML for canvas app screens, following the official Power Apps YAML source format rules and a consistent enterprise design system.
Before Starting
Always confirm the following before generating any YAML:
- Screen or component name — what to name the output (e.g.
ScnDashboard,ScnRequestForm,DlgConfirmDelete) - Component type — full screen, dialog/overlay, form, gallery list, detail view, dashboard, or other
- Navigation context — if a sidebar is needed, which nav item should be active; if no sidebar is needed, say so
- Screen purpose — one sentence describing what the screen or component does
- Data source — SharePoint list, Dataverse table, or collection name and any known column names (if data-driven)
- Controls needed — gallery, form fields, dropdowns, status badges, buttons, dialogs, etc.
If any detail is missing, ask before generating.
Step 1: Confirm the Component Type
The component type determines the top-level YAML structure:
- Full screens → wrapped in
Screens:block - Dialogs, popups, components, partial UI → bare container tree, NO
Screens:wrapper
| Type | Screens: wrapper? | When to use |
|---|---|---|
| Full screen with sidebar | YES | A primary app screen with global navigation |
| Full screen without sidebar | YES | A login, splash, or single-purpose screen |
| Dialog / overlay / popup | NO | A confirmation, quick-entry panel, or modal overlaid on another screen |
| Reusable component / card | NO | A panel, card, or UI fragment embedded within a screen |
| Standalone form screen | YES | A dedicated create or edit screen without a sidebar |
| Gallery list screen | YES | A searchable, filterable list of records |
| Detail view screen | YES | A read-only or editable single-record view |
| Dashboard screen | YES | A summary screen with KPI cards |
| Custom / other | Ask | Describe it |
What ships with it
3 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.

powerapps-canvas-yaml-generator is a skill published in the GitHub repository pnp/copilot-prompts (902 stars, last pushed yesterday), licensed MIT. It adds 79 tokens to every session and 10,868 once invoked, about $0.0003 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 2026-08-30.
