+# Learner Tools Slot
+
+### Slot ID: `org.openedx.frontend.learning.learner_tools.v1`
+
+### Slot ID Aliases
+* `learner_tools_slot`
+
+### Description
+This plugin slot provides a location for learner-facing tools and features to be displayed during course content navigation. The slot is rendered via a React portal to `document.body` to ensure proper positioning and stacking context.
+
+### Props:
+* `courseId` - The unique identifier for the current course
+* `unitId` - The unique identifier for the current unit/vertical being viewed
+* `userId` - The authenticated user's ID (automatically retrieved from auth context)
+* `isStaff` - Boolean indicating whether the user has staff/instructor privileges
+* `enrollmentMode` - The user's enrollment mode (e.g., 'audit', 'verified', 'honor', etc.)
+
+### Usage
+Plugins registered to this slot can use the provided context to:
+- Display course-specific tools based on courseId and unitId
+- Show different features based on user's enrollment mode
+- Provide staff-only functionality when isStaff is true
+- Query additional data from Redux store or backend APIs as needed
+
+### Notes
+- Returns `null` if user is not authenticated
+- Plugins should manage their own feature flag checks and requirements
+- The slot uses a portal to render to `document.body` for flexible positioning
