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 | $0.07175 | $0.07175 |
| Opus 5 | $0.03587 | $0.03587 |
| Sonnet 5 | $0.01435 | $0.01435 |
| Haiku 4.5 | $0.00717 | $0.00717 |
Grade A, and why
PowerPlatform-PowerPagesSPA 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 6d 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.

Power Pages SPA Development Guide
This guide covers Power Pages SPA-specific setup and integration. For general React development, Fluent UI 9 patterns, routing, and UI best practices, refer to React-SPA.instructions.md.
Power Pages SPA Workflow:
- Create React SPA project (standard Vite + React + TypeScript) inside
/PowerPagesSPAfolder - Configure Power Pages deployment settings
- Upload and deploy to Power Pages
- Configure authentication and authorization
- Use Power Pages Web API for data access
For React Development: See React-SPA.instructions.md for:
- Complete folder structure and organization
- Fluent UI 9 components and theming
- React Router implementation
- Performance optimization
- Responsive design patterns
- Accessibility guidelines
Important Notes
Preview Feature: Power Pages SPA sites are currently in preview and subject to change.
Client-Side Rendering Only: Power Pages SPA sites run entirely in the user's browser, unlike traditional Power Pages sites.
Source Code Management: SPA sites are managed only through source code and CLI tools (no visual designer).
1. Prerequisites
Before you begin, make sure you have:
- A Power Pages environment with admin privileges
- Power Platform CLI (PAC CLI) version 1.44.x or later installed and authenticated
- A Power Pages site on version 9.7.4.x or later
- Node.js (LTS version)
- Visual Studio Code
Verify PAC CLI Authentication
pac org who
If you are not authenticated, authenticate first:
pac auth create --name "MyProfile" --environment <environment-url>
2. Create Power Pages SPA Project
Step 1: Initialize React Project
Create a standard React + TypeScript project using Vite:
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.
