Migrate an InfoPath Form to a Canvas App

Migrate the InfoPath form described below:

$ARGUMENTS

A .xsn is a CAB archive containing manifest.xsf (rules, views, data connections), schema*.xsd (data schema), template.xml (defaults), and XSL views. This skill runs three phases: extract → inventory → hand off to generate-canvas-app. Pause for user approval after the inventory.

---

Phase 0 — Extract

From $ARGUMENTS, resolve a .xsn path. If the user gave a folder, Glob for *.xsn inside; ask if there are multiple or none.

If a sibling xsn_extracted/ already contains manifest.xsf, reuse it. Otherwise extract to <source_dir>/xsn_extracted/:

• Windows: & "$env:SystemRoot\System32\expand.exe" "<form>.xsn" -F:* "<xsn_extracted>" via PowerShell
• macOS / Linux: cabextract -d <xsn_extracted> <form>.xsn

Verify manifest.xsf and schema1.xsd exist; abort if not.

Phase 1 — Inventory

Spawn a general-purpose Agent to write infopath-inventory.md covering:

• Fields — from schema1.xsd + template.xml dfs:dataFields: decoded name, type (Text, Date, Number, Choice, multi-Choice, Person, NoteEnhanced/rich-text, Lookup, …), constraints (maxLength, pattern, enumeration, minOccurs/nillable), default. Decode URL-encoded names: _x0020_=space, _x0028_=(, _x0029_=), _x002d_=-, _x0023_=#, _x0026_=&.
• Rules — from manifest.xsf: schema-required fields, xsf:errorCondition (field + XPath translated to plain English + message), xsf:ruleSet/xsf:domEventHandler (trigger, condition, action), xsf:submit destination.
• Lookup connections — every non-schema*.xsd schema: source name + columns used.
• Views — section headings and field ordering from the XSL views; note multiple views.
• Section recommendation — propose logical sections of 10–30 fields each for Canvas.

After the agent returns, surface counts (fields / rules / connections / sections) and ask:

1. Mock with collections in App.OnStart (default), or wire to real SharePoint?
2. Keep all sections, or drop any?
3. Aesthetic preferences? (default: clean professional)

Wait for answers.

If the user wants to wire to real SharePoint, strongly suggest they add the SharePoint list(s) as a data source in the app before generation — Canvas can't bind to a connection that doesn't exist in the app. Tell them the steps (Power Apps Studio → Data → Add data → SharePoint → pick site/list) and that this skill can verify the schema once it's done.

When they confirm, call mcp__canvas-authoring__list_data_sources to see what's connected, then mcp__canvas-authoring__get_data_source_schema for each list. Diff against the inventory: every InfoPath field should map to a SharePoint column of compatible type. Report any missing columns, type mismatches (e.g. InfoPath Date vs. SP Text), or extra-required columns the form doesn't populate. Pause and let the user reconcile (rename columns, add missing ones, or trim the inventory) before Phase 2.

Phase 2 — Hand off to generate-canvas-app

Write canvas-app-prompt.md containing:

• The kept sections + field lists with type hints (call out dates, multi-choice, rich text).
• Each InfoPath rule restated as the desired Canvas behavior in plain English (the inner skill maps to Power Fx).
• Mock-data plan if mocking: 3–5 sample records per section, plus choice-list collections seeded from enumerations / lookup tables.
• The user's aesthetic answer.
• Validation should block submit (DisplayMode.Disabled on Save buttons) — an intentional upgrade from InfoPath's flag-but-don't-block behavior; flag this as a deliberate change.

Then invoke generate-canvas-app via the Skill tool, passing the prompt as args. If that skill isn't available, instruct the user to run /generate-canvas-app against canvas-app-prompt.md.
