Token cost

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.

Security

Grade C, and why

create-site scanned grade C 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 8d ago.

The scan reads SKILL.md. This mod also ships 14 executable files (assets/angular/src/app/app.component.ts, assets/angular/src/app/app.config.ts, assets/angular/src/app/app.routes.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 2,174 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.

Create Power Pages Code Site

Guide the user through creating a complete, production-quality Power Pages code site from initial concept to deployed site. Follow a systematic approach: discover requirements, scaffold and launch immediately, plan components and design, implement with design applied, validate, review, and deploy.

Core Principles

  • Design for the first impression: The site must make the user say "wow" the moment the Home page replaces the scaffold, and keep earning it on every page. Once the user answers the aesthetic, mood, and brand questions, make confident decisions about fonts, colors, layouts, imagery, and motion yourself - the design references (design-aesthetics.md, page-blueprints.md, design-critique.md under ${PLUGIN_ROOT}/references/) define the bar, and your own taste fills the rest.
  • Use TaskCreate/TaskUpdate: Track all progress throughout all phases — create the path-agnostic upfront tasks first, then append branch-specific tasks after the creation path is selected.
  • Scaffold early, design with intention: Get the dev server running immediately after discovery so the user has something to look at. Then plan the design and features while the scaffold is live — apply the chosen aesthetic during implementation.
  • Live preview feedback loop: The dev server MUST be running before any customization begins. Browse the site via Playwright (browser_navigate + browser_snapshot) to verify the structure of every significant change. Visual design review captures every page with one script call and opens the screenshots in one turn (see 5.7); use Playwright MCP screenshots only for brand extraction in Phase 3.
  • Keep the scaffold loader in sync with reality: The scaffold loader polls public/scaffold-status.json. Update this file before every AskUserQuestion (to raise the "waiting for your input" banner so the user doesn't miss a terminal prompt) and before each implementation step in Phase 5 (so the progress-bar label matches what you're actually doing while the decorative spinner continues its default cycle). See Live Preview Status Protocol.
  • Use purposeful visuals: Every image explains, orients, demonstrates, or reinforces identity. Prefer the site's own UI composed as a product moment, then bespoke inline SVG, then specific Unsplash photography with one art direction (see 5.3). Never leave image placeholders or broken <img> tags pointing to nonexistent files.
  • Git checkpoints: Commit after every individual page and component — each gets its own commit so breaking changes can be reverted.
  • Site content language is independent of Dataverse language: Generate every user-visible SPA string in the approved content language. Dataverse and Power Pages platform-managed messages remain English (en-US, LCID 1033) in this workflow.
  • Bidirectional by default: Read ${PLUGIN_ROOT}/references/bidirectional-design.md. Every site must use direction-neutral layout, mixed-content boundaries, and script-capable typography even when its initial language has only one direction. A later LTR/RTL locale must not require a general redesign.
  • Lifecycle-ready output: Follow ${PLUGIN_ROOT}/references/site-modification-integrity.md so later pages and components can preserve localization, direction, and content-expansion behavior through the shared post-modification validator.

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.
