Add Sharepoint Agent Skill

📋 Shared instructions: shared-instructions.md — read first.

References:

• sharepoint-reference.md — Column encoding, choice fields, lookups, API patterns (CRITICAL)
• api-authentication-reference.md — Graph API auth, token, site ID
• list-management-reference.md — Query, create, extend lists and columns

Add SharePoint

Two paths: existing lists (skip to Step 6) or new lists (full workflow).

Workflow

• Check Memory Bank → 2. Plan → 3. Setup Graph API Auth → 4. Review Existing Lists → 5. Create Lists → 6. Get Connection ID → 7. Discover Sites → 8. Discover Tables → 9. Add Connector → 10. Configure → 11. Type-check → 12. Update Memory Bank

Step 1: Check Memory Bank

Check for memory-bank.md per shared-instructions.md.

Also confirm this is a mobile app:

test -f power.config.json && test -f app.config.js && echo "OK" || echo "ERROR: not a mobile app"

Step 2: Plan

Ask the user:

• Which SharePoint list(s) do they need?
• Do the lists already exist on their site, or do they need to create new ones?

If lists already exist: Skip to Step 6.

If creating new lists:

• Ask about the data they need and design an appropriate schema
• Reuse existing lists when possible (don't duplicate)
• Enter plan mode with EnterPlanMode, present the list designs with columns and types
• Get approval with ExitPlanMode

Step 3: Setup Graph API Auth (if creating lists)

See api-authentication-reference.md for full details.

az account show   # Verify Azure CLI logged in

$api = Initialize-SharePointGraphApi -SiteUrl "https://<tenant>.sharepoint.com/sites/<site-name>"
$headers = $api.Headers
$siteId = $api.SiteId

Requires Sites.Manage.All permission.

Step 4: Review Existing Lists (if creating lists)

Always query existing lists first before creating:

$existingLists = Invoke-RestMethod -Uri "https://graph.microsoft.com/v1.0/sites/$siteId/lists?`$select=id,displayName,description,list&`$filter=list/hidden eq false" -Headers $headers

See list-management-reference.md for Find-SimilarLists, Compare-ListSchemas, and Get-ListSchema functions.

Present findings to user with AskUserQuestion:

• Lists that can be reused (already exist with matching columns)
• Lists that need extension (exist but missing columns)
• Lists that must be created (no match found)

Step 5: Create Lists (if creating lists)

Print before starting:

> "→ Creating SharePoint lists via Graph API (sequential per list, columns added after list exists)…"

Get explicit confirmation before creating. Use safe functions from list-management-reference.md:

• New-SharePointListIfNotExists
• Add-SharePointColumnIfNotExists
• Add-SharePointLookupColumn (for cross-list references)

Step 6: Get Connection ID

Get the SharePoint Online connection ID (see connector-reference.md):

npx power-apps create-connection --api-id shared_sharepointonline --json

Use shared_sharepointonline as the apiId and capture connectionId from the output. Use these exact values in the commands below.

If create-connection cannot complete because browser-based connection creation is disabled or the connector needs interactive auth, direct the user to create one:

> Open https://make.powerapps.com/environments/<environment-id>/connections → + New connection → search "SharePoint" → Create. Then provide the connection ID or rerun /list-connections shared_sharepointonline.

Step 7: Discover Sites

Print before starting:

> "→ Discovering SharePoint sites accessible to this connection…"

npx power-apps list-datasets --api-id <apiId-from-list> --connection-id <connection-id> --json

Present the sites to the user and ask which one(s) they want to connect to. If the user already specified a site URL, confirm it appears in the list.

If npx power-apps list-datasets fails or returns no results:

• Auth, wrong user, or multiple accounts: follow shared-instructions command-failure handling and retry once.
• Empty list: Confirm the connection ID is for a SharePoint Online connection and the user has access to at least one site. STOP if the list is empty after confirming.

Step 8: Discover Tables

Print before starting:

> "→ Discovering lists/document libraries on each selected site…"

For each selected site:

npx power-apps list-tables --api-id <apiId-from-list> --connection-id <connection-id> --dataset '<site-url>' --json

Present the tables to the user and ask which ones they want to add. Suggest tables that look relevant to their use case. If lists were created in Step 5, they should appear here.

Step 9: Add Connector

Print before starting:

> "→ Running npx power-apps add-data-source per list (sequential, ~10–20 seconds each)."

SharePoint is a tabular datasource — requires --connection-id, --dataset, and --resource-name:

npx power-apps add-data-source --api-id <apiId-from-list> --connection-id <connectionId-from-list> --dataset '<site-url>' --resource-name '<table-name>'

Run once per list or document library.

Step 10: Configure

Read sharepoint-reference.md before writing any SharePoint code — column encoding, choice fields, and lookups have critical gotchas.

Use Grep to find methods in src/generated/services/SharePointOnlineService.ts (generated files can be very large — see connector-reference.md).

Sample usage:

import { SharePointOnlineService } from '../../src/generated/services/SharePointOnlineService';

// Read items
const result = await SharePointOnlineService.GetItems({
  dataset: 'https://contoso.sharepoint.com/sites/projects',
  table: 'Project Milestones',
});
const items = result.value ?? [];

// Create item
await SharePointOnlineService.PostItem({
  dataset: 'https://contoso.sharepoint.com/sites/projects',
  table: 'Project Milestones',
  item: { Title: 'Launch review', Status: 'Not Started' },
});

// Update item (SharePoint IDs are integers, not GUIDs)
await SharePointOnlineService.PatchItem({
  dataset: 'https://contoso.sharepoint.com/sites/projects',
  table: 'Project Milestones',
  id: 42,
  item: { Status: 'Done' },
});

Step 11: Type-check

Print before starting:

> "→ Regenerating connector schemas + running tsc to verify SharePoint services compile (~15–30 seconds)."

> Native diff: npx tsc --noEmit instead of npm run build. Do NOT run platform-specific native build commands here.

npx power-apps add-data-source wrote new files into .power/schemas/sharepointonline/. Regenerate connectorSchemas.ts before type-checking so the new list is wired into the runtime schema map:

npm run generate-schemas
npx tsc --noEmit

Fix TypeScript errors before proceeding.

Step 12: Update Memory Bank

Update memory-bank.md with: connector added, site URL, lists/libraries connected (or created), type-check status.

> Note: No manual executor wiring needed. PowerAppsProvider in app/_layout.tsx handles SharePoint connector routing, connection resolution, and OAuth consent automatically at runtime.
