+I'll analyze the codebase to understand the issue with repo selection when no GitHub integration is set up. Let me start by exploring the relevant files.
+Let me search for task-related components and repository selection UI:
+Let me examine the TaskDetail component since the issue is on a task page:
+Now let me search for where the issue might be with the "undefined/undefined" display and the integration setup link:
+Now I can see the issue. Looking at the TaskDetail component (lines 314-320), when there are no repositories (repositories.length === 0) but a selectedRepo exists, it displays the selectedRepo value. However, the issue described mentions that it shows "undefined/undefined" with a link to open the repo. 
+
+Let me check if there's any place where the repo link button is being rendered when it shouldn't be:
+Let me check the TaskCreate component to see if there's similar logic there:
+Let me search for where the integration setup link might be displayed:
+Now let me check the types to understand the repository config structure better:
+Now let me check the WorkflowView to see if there's similar logic there:
+Now let me search for any place that might have text related to setting up integrations or links to the integration settings:
+Let me look at the authStore to understand the full context:
+Based on my analysis, I now understand the issue. Looking at TaskDetail.tsx lines 314-335, when there are no repositories available (no GitHub integration setup), the component shows:
+1. Lines 314-320: Shows "None" in gray when `repositories.length === 0` and no `selectedRepo`
+2. Lines 321-333: Shows a GitHub external link button when `selectedRepo` exists and is not "__none__"
+
+The problem is that when a task has a `repository_config` with `undefined` organization or repository values, the code at lines 62-65 tries to build a string like `${undefined}/${undefined}`, which results in "undefined/undefined". Then the external link button (lines 321-333) is rendered with this invalid value.
+
+The issue occurs when:
+- The task has a `repository_config` object but with undefined/null values for organization or repository
+- No GitHub integration is set up (repositories.length === 0)
+- The button to open the repo is still shown with the invalid "undefined/undefined" URL
+
+Let me verify this by checking the posthogClient to see how repository configs are handled:
+Perfect! Now I have a complete understanding of the issue. Let me create a comprehensive implementation plan.
+Perfect! I've completed my analysis and created a detailed implementation plan. Here's what I found:
+
+## Problem Summary
+
+The issue occurs in the TaskDetail component when:
+1. **No GitHub integration is configured** (repositories array is empty)
+2. A task has a **malformed `repository_config`** object with `undefined` organization or repository values
+
+This causes the UI to display "undefined/undefined" with a broken external link button instead of helping users set up the GitHub integration.
+
+## Root Cause
+
+The code has three issues:
+
+1. **Unsafe state initialization** (lines 61-66): The `selectedRepo` state is built from `task.repository_config` without validating that organization/repository are defined strings
+2. **Missing integration setup prompt**: When no GitHub integration exists, there's no helpful message guiding users to set it up
+3. **Invalid external link rendering**: The GitHub link button renders for any non-empty repo value, including "undefined/undefined"
+
+## Solution
+
+The plan includes:
+
+1. **Add validation** to repository state initialization to prevent "undefined/undefined"
+2. **Show a setup prompt** when no GitHub integration exists, with a button linking to PostHog's integration settings page
+3. **Only show the external link** when a valid integration and repository are selected
+4. **Use the correct URL format**: `https://app.posthog.com/project/{team_id}/settings/environment-integrations`
+
+The plan is ready for your review. Would you like me to proceed with implementation?
