A set of instructions for building Power Pages, Microsoft's websites and portals that can show Dataverse data to customers, partners, or other external users.

It supports customer and partner portals, sign-in, web roles, table permissions, data lists and forms, Liquid templates, portal JavaScript, and site settings.

It helps control who external visitors are, what data they can access, and how portal pages and forms behave.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.02182
Opus 5.5	$0.00022	$0.00873
Sonnet 5.5	$0.00011	$0.00436
Haiku 4.5	$0.00005	$0.00218

Measured 2mo ago against content hash bd948854ef06, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

power-pages 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 2mo 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.

Skill: Power Pages (External Portals)

When to Use

Trigger when building external-facing websites on Dataverse — customer portals, partner portals, self-service portals, community forums, or any authenticated web experience exposing Dataverse data to external users.

When to Use Power Pages vs Alternatives

Scenario	Best Choice	Why
External customer self-service portal	Power Pages	Built-in Dataverse integration, external auth
Internal business app	Model-Driven or Canvas App	Simpler, no portal overhead
Public marketing website	Azure Static Web Apps / WordPress	Power Pages is overkill
External API for partners	Custom Connector + APIM	No UI needed
Complex custom frontend for externals	Code App + Microsoft Entra ID B2C	Full React control
Simple form intake from externals	Power Pages or Microsoft Forms	Depends on data destination

⚠️ REQUIRED: Load Sub-Files Before Implementation

SKILL.md is a summary only — it is NOT sufficient for implementation.

The detailed content (complete payloads, XML templates, working examples, edge-case handling) lives in sub-files in the same directory as this SKILL.md. Before writing any code, you MUST use read_file on the sub-files relevant to your task:

Web Roles & Table Permissions — Web roles, table permission scopes (Global/Contact/Account/Parent/Self), page permissions, Append/AppendTo rules
Liquid Templating — Variables, conditionals, loops, FetchXML in Liquid, Web API in Liquid, content snippets
Entity Lists, Forms & Web Forms — Entity lists (data grids), entity forms (single-record CRUD), form metadata overrides, web forms (multi-step wizards)
Authentication — Identity providers, Microsoft Entra ID B2C setup, Contact = User model, auth in Code Sites
Custom JavaScript & Portal Web API — Entity form scripts, client-side AJAX via Portal Web API, enabling Web API via site settings, Client APIs (Wave 1 2026) for Form/List/User/Web API
Code Sites (SPA) — Framework reference, PAC CLI workflow, Web API client pattern (anti-forgery token), service patterns, lookup rules, table permissions for Code Sites
Agent API — Agent API for Power Pages (March 2026), custom chat experiences backed by Copilot Studio agents, API endpoints, authentication, custom UI

What ships with it

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.
