**References:**

• [sharepoint-reference.md](./references/sharepoint-reference.md) - Column encoding, choice fields, lookups, API patterns (CRITICAL)
• [api-authentication-reference.md](./references/api-authentication-reference.md) - Graph API auth, token, site ID
• [list-management-reference.md](./references/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

1. 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. Build → 12. Update Memory Bank

---

Step 1: Check Memory Bank

Check for `memory-bank.md` per [shared-instructions.md](${PLUGIN_ROOT}/shared/shared-instructions.md).

Step 2: Plan

Ask the user:

1. Which SharePoint list(s) do they need? 2. 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](./references/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](./references/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)

Get explicit confirmation before creating. Use safe functions from [list-management-reference.md](./references/list-management-reference.md):

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

Step 6: Get Connection ID

Find the SharePoint Online connection ID (see [connector-reference.md](${PLUGIN_ROOT}/shared/connector-reference.md)):

Run the `/list-connections` skill. Find the SharePoint Online connection in the output. If none exists, direct the user to create one using the environment-specific Connections URL — construct it from the active environment ID in context (from `power.config.json` or a prior step): `https://make.powerapps.com/environments/<environment-id>/connections` → **+ New connection** → search for the connector → Create.

Step 7: Discover Sites

List available SharePoint sites the user has access to:

pa connector list-datasets --connector sharepointonline -c <connection-id>

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 `pa connector list-datasets` fails or returns no results:**

• Auth error: Run `pa auth logout` (or `power-apps logout` on `power-apps`-only projects), then retry — the CLI will re-prompt browser login.
• 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.
• Any other non-zero exit: Report the exact error output. STOP.

Step 8: Discover Tables

For each selected site, list the available lists and document libraries:

pa connector list-tables --connector sharepointonline -c <connection-id> -d '<site-url>'

**If `pa connector list-tables` fails or returns no results:**

• Confirm the site URL from Step 7 is exact (copy from the output — do not retype).
• If still empty, the user may not have access to that site's lists. Ask them to verify permissions in SharePoint.
• Any other non-zero exit: Report the exact error output. STOP.

Present the tables to the user and ask which ones they want to add. Suggest tables that look relevant to their use case (based on memory bank context or the user's stated requirements). If lists were created in Step 5, they should appear here.

Step 9: Add Connector

SharePoint is a tabular datasource -- requires `-c` (connection ID), `-d` (site URL), and `--table` (list name):

pa app add data-source --connector sharepointonline -c <connection-id> -d '<site-url>' --table '<table-name>'

Run the command for each list or library the user selected. The `-d` (dataset) is the SharePoint site URL from Step 7, `--table` is the list/library name from Step 8.

Step 10: Configure
