-# Implementation Plan: SECRT-1928 - Delete Chat Sessions
-
-**Ticket:** [SECRT-1928](https://linear.app/autogpt/issue/SECRT-1928)
-**Author:** Otto
-**Date:** 2026-02-14
-
-## Summary
-
-Add the ability for users to delete chat sessions from the CoPilot interface. The backend logic already exists (`delete_chat_session` in `model.py` and `db.py`), it just needs a route and frontend UI.
-
-## Current State
-
-### Backend (already exists)
-- `backend/api/features/chat/db.py:delete_chat_session()` - DB deletion with user ownership validation
-- `backend/api/features/chat/model.py:delete_chat_session()` - Handles cache cleanup and lock removal
-- **Missing:** No DELETE route in `routes.py`
-
-### Frontend
-- `ChatSidebar.tsx` displays session list with no delete option
-- `MobileDrawer.tsx` also needs delete option
-- **Missing:** Delete button, confirmation dialog, API call
-
-## Implementation
-
-### Phase 1: Backend Route (15 min)
-
-**File:** `autogpt_platform/backend/backend/api/features/chat/routes.py`
-
-Add after line ~200 (after `create_session`):
-
-```python
-@router.delete(
-    "/sessions/{session_id}",
-    dependencies=[Security(auth.requires_user)],
-    status_code=204,
-)
-async def delete_session(
-    session_id: str,
-    user_id: Annotated[str, Security(auth.get_user_id)],
-) -> Response:
-    """
-    Delete a chat session.
-
-    Permanently removes a chat session and all its messages.
-    Only the owner can delete their sessions.
-
-    Args:
-        session_id: The session ID to delete.
-        user_id: The authenticated user's ID.
-
-    Returns:
-        204 No Content on success.
-
-    Raises:
-        404: Session not found or not owned by user.
-    """
-    from .model import delete_chat_session
-    
-    deleted = await delete_chat_session(session_id, user_id)
-    
-    if not deleted:
-        raise HTTPException(
-            status_code=404,
-            detail=f"Session {session_id} not found or access denied"
-        )
-    
-    return Response(status_code=204)
-```
-
-**Add import at top:**
-```python
-from fastapi import Response  # add to existing imports
-```
-
-### Phase 2: Frontend API Hook (auto-generated)
-
-After adding the backend route, run the OpenAPI generator to create the hook:
-```bash
-cd autogpt_platform/frontend
-pnpm generate:api
-```
-
-This will generate `useDeleteV2Session` or similar.
-
-### Phase 3: Frontend UI (30 min)
-
-**File:** `autogpt_platform/frontend/src/app/(platform)/copilot/components/ChatSidebar/ChatSidebar.tsx`
-
-1. Add imports:
-```tsx
-import { TrashIcon } from "@phosphor-icons/react";
-import { useDeleteV2Session } from "@/app/api/__generated__/endpoints/chat/chat";
-import { useQueryClient } from "@tanstack/react-query";
-import {
-  AlertDialog,
-  AlertDialogAction,
-  AlertDialogCancel,
-  AlertDialogContent,
-  AlertDialogDescription,
-  AlertDialogFooter,
-  AlertDialogHeader,
-  AlertDialogTitle,
-} from "@/components/ui/alert-dialog";
-```
-
-2. Add state and mutation hook inside component:
-```tsx
-const [sessionToDelete, setSessionToDelete] = useState<string | null>(null);
-const queryClient = useQueryClient();
-
-const { mutate: deleteSession, isPending: isDeleting } = useDeleteV2Session({
-  mutation: {
-    onSuccess: () => {
-      // Invalidate sessions list to refetch
-      queryClient.invalidateQueries({ queryKey: ['v2', 'sessions'] });
-      // If we deleted the current session, clear selection
-      if (sessionToDelete === sessionId) {
-        setSessionId(null);
-      }
-      setSessionToDelete(null);
-    },
-    onError: (error) => {
-      console.error("Failed to delete session:", error);
-      setSessionToDelete(null);
-    },
-  },
-});
-
-function handleDeleteClick(e: React.MouseEvent, id: string) {
-  e.stopPropagation(); // Prevent session selection
-  setSessionToDelete(id);
-}
-
-function handleConfirmDelete() {
-  if (sessionToDelete) {
-    deleteSession({ sessionId: sessionToDelete });
-  }
-}
-```
-
-3. Add delete button to each session item (inside the session button, after the date):
-```tsx
-<button
-  onClick={(e) => handleDeleteClick(e, session.id)}
-  className="absolute right-2 top-1/2 -translate-y-1/2 opacity-0 group-hover:opacity-100 
-             p-1.5 rounded hover:bg-red-100 text-zinc-400 hover:text-red-600 transition-all"
-  aria-label="Delete chat"
->
-  <TrashIcon className="h-4 w-4" />
-</button>
-```
-
-4. Add confirmation dialog before the closing `</Sidebar>`:
-```tsx
-<AlertDialog open={!!sessionToDelete} onOpenChange={(open) => !open && setSessionToDelete(null)}>
-  <AlertDialogContent>
-    <AlertDialogHeader>
-      <AlertDialogTitle>Delete this chat?</AlertDialogTitle>
-      <AlertDialogDescription>
-        This will permanently delete this conversation and all its messages. This action cannot be undone.
-      </AlertDialogDescription>
-    </AlertDialogHeader>
-    <AlertDialogFooter>
-      <AlertDialogCancel disabled={isDeleting}>Cancel</AlertDialogCancel>
-      <AlertDialogAction 
-        onClick={handleConfirmDelete}
-        disabled={isDeleting}
-        className="bg-red-600 hover:bg-red-700"
-      >
-        {isDeleting ? "Deleting..." : "Delete"}
-      </AlertDialogAction>
-    </AlertDialogFooter>
-  </AlertDialogContent>
-</AlertDialog>
-```
-
-5. Update session button to have `group` class for hover effects:
-```tsx
-<button
-  key={session.id}
-  onClick={() => handleSelectSession(session.id)}
-  className={cn(
-    "group relative w-full rounded-lg px-3 py-2.5 pr-10 text-left transition-colors",  // added group, relative, pr-10
-    ...
-  )}
->
-```
-
-### Phase 4: Mobile Drawer Update (15 min)
-
-**File:** `autogpt_platform/frontend/src/app/(platform)/copilot/components/MobileDrawer/MobileDrawer.tsx`
-
-Similar pattern - add delete button with swipe-to-delete or long-press context menu for mobile UX.
-
-## Testing
-
-1. **Backend:** 
-   - `DELETE /api/v2/chat/sessions/{id}` returns 204 for valid session
-   - Returns 404 for invalid/unowned session
-   - Verify messages are cascade deleted (Prisma handles this)
-
-2. **Frontend:**
-   - Hover shows delete icon
-   - Click shows confirmation
-   - Cancel dismisses dialog
-   - Confirm deletes and refreshes list
-   - Deleting current session clears selection
-
-## Migration/Rollback
-
-None required - additive change only.
-
-## Verified ✅
-
-1. **`delete_chat_session` return behavior:** Returns `bool` - `True` if deleted successfully, `False` otherwise (not owned/not found). No exception raised. The route code is correct.
-
-2. **Query key for cache invalidation:** Should use `getGetV2ListSessionsQueryKey()` from the generated code, not hardcoded `['v2', 'sessions']`. Fix:
-   ```tsx
-   import { getGetV2ListSessionsQueryKey } from "@/app/api/__generated__/endpoints/chat/chat";
-   // ...
-   queryClient.invalidateQueries({ queryKey: getGetV2ListSessionsQueryKey() });
-   ```
-
-3. **`setSessionId` availability:** Available from `useQueryState("sessionId", parseAsString)` already in component scope.
-
-## Open Questions
-
-1. Should we support bulk delete? (Deferred - out of scope for this ticket)
-2. Soft delete vs hard delete? (Hard delete per Zamil's request - "idc")

-# Implementation Plan: SECRT-1959 - Agent Builder Graph Desync (Edge Deletion Not Persisting)
-
-**Ticket:** [SECRT-1959](https://linear.app/autogpt/issue/SECRT-1959)
-**Author:** Otto
-**Date:** 2026-02-14
-**Priority:** Urgent
-
-## Problem Statement
-
-Edge deletions in the Agent Builder are not persisting correctly. When users delete edges between nodes, the deletion doesn't stick — causing stale/orphan node connections across builds that cannot be corrected.
-
-**Impact:**
-- Users CANNOT delete edge endpoints to fix corrupt builds
-- Workarounds (duplicating agents) are wasteful
-- Agents end up with broken wiring that can't be repaired
-
-## Root Cause Analysis
-
-### Current Flow
-1. User deletes edge → `edgeStore.removeEdge()` removes from Zustand state
-2. User saves → `useSaveGraph` calls `getBackendLinks()` to get current edges
-3. Backend creates new graph version with provided nodes/links
-4. On reload, `useFlow` loads `graph.links` from backend into edge store
-
-### Potential Failure Points
-
-1. **Frontend state not syncing properly** - Edge removal might not be captured when save happens
-2. **Draft manager interference** - `useDraftManager.ts` manages local drafts, might restore old state
-3. **React Query cache** - Stale data might be served after save
-4. **Backend not returning authoritative state** - Frontend might not update with server response
-
-## Investigation Steps (Before Implementation)
-
-**Need to verify:**
-1. Is `getBackendLinks()` returning correct edges at save time?
-2. Is the backend receiving the correct links in the update request?
-3. Is the backend returning the new graph version with correct links?
-4. Is the frontend updating from the backend response?
-
-Add debug logging to trace the flow:
-
-```typescript
-// In useSaveGraph.ts, before save:
-console.log('[SAVE] Links being sent:', useEdgeStore.getState().getBackendLinks());
-
-// After save response:
-console.log('[SAVE] Links returned:', response.data.links);
-```
-
-## Proposed Fix
-
-### Phase 1: Frontend - Ensure State Consistency (Primary Fix)
-
-**File:** `autogpt_platform/frontend/src/app/(platform)/build/hooks/useSaveGraph.ts`
-
-After save completes, sync the edge store with the authoritative backend state:
-
-```typescript
-// In onSuccess callback after save
-const { mutateAsync: updateGraph, isPending: isUpdating } =
-  usePutV1UpdateGraphVersion({
-    mutation: {
-      onSuccess: async (response) => {
-        const data = response.data as GraphModel;
-        
-        // ... existing code ...
-        
-        // CRITICAL: Sync edge store with authoritative backend state
-        if (data.links) {
-          useEdgeStore.getState().setEdges([]);
-          useEdgeStore.getState().addLinks(data.links);
-        }
-        
-        onSuccess?.(data);
-        // ... rest of handler
-      },
-    },
-  });
-```
-
-Same fix needed in `createNewGraph` mutation handler.
-
-### Phase 2: Backend - Add Orphan Edge Validation (Defense in Depth)
-
-**File:** `autogpt_platform/backend/backend/data/graph.py`
-
-In `Graph.validate_graph()` or a new method, add orphan edge pruning:
-
-```python
-def normalize_links(self) -> list[Link]:
-    """Remove orphan links that reference non-existent nodes."""
-    valid_node_ids = {node.id for node in self.nodes}
-    original_count = len(self.links)
-    
-    valid_links = [
-        link for link in self.links
-        if link.source_id in valid_node_ids and link.sink_id in valid_node_ids
-    ]
-    
-    pruned_count = original_count - len(valid_links)
-    if pruned_count > 0:
-        logger.warning(
-            f"Pruned {pruned_count} orphan link(s) from graph {self.id}"
-        )
-    
-    return valid_links
-```
-
-Call this in `validate_graph()` or in `__create_graph()` before persisting:
-
-```python
-async def __create_graph(tx, graph: Graph, user_id: str):
-    # Normalize links before saving
-    graph.links = graph.normalize_links()
-    
-    graphs = [graph] + graph.sub_graphs
-    # ... rest of function
-```
-
-### Phase 3: Frontend - Invalidate React Query Cache (Belt and Suspenders)
-
-**File:** `autogpt_platform/frontend/src/app/(platform)/build/hooks/useSaveGraph.ts`
-
-Ensure React Query refetches fresh data:
-
-```typescript
-import { useQueryClient } from "@tanstack/react-query";
-
-// In the hook:
-const queryClient = useQueryClient();
-
-// In onSuccess:
-onSuccess: async (response) => {
-  const data = response.data as GraphModel;
-  
-  // Invalidate and refetch the graph query
-  await queryClient.invalidateQueries({
-    queryKey: ['v1', 'graphs', data.id],
-  });
-  
-  // ... rest of handler
-}
-```
-
-### Phase 4: Draft Manager Safety (Prevent Stale Restore)
-
-**File:** `autogpt_platform/frontend/src/app/(platform)/build/components/FlowEditor/Flow/useDraftManager.ts`
-
-Review draft restore logic to ensure it doesn't restore stale edge state after a save. The draft should be invalidated after a successful save (already happens in `useSaveGraph.ts`):
-
-```typescript
-// After save success in useSaveGraph.ts (already exists):
-if (data.id) {
-  await draftService.deleteDraft(data.id);
-}
-```
-
-Verify this is working correctly.
-
-## Testing Plan
-
-### Manual Testing
-1. Create agent with 3+ nodes and edges
-2. Delete an edge
-3. Save the graph
-4. Refresh the page
-5. Verify edge is still deleted
-6. Check different scenarios:
-   - Delete edge, save, close tab, reopen
-   - Delete edge, save, navigate away, navigate back
-   - Delete multiple edges, save
-
-### Automated Testing
-Add integration test:
-
-```typescript
-// In a test file
-it('should persist edge deletion after save and reload', async () => {
-  // Create graph with edge
-  // Delete edge from store
-  // Save graph
-  // Clear stores
-  // Reload graph
-  // Assert edge is not present
-});
-```
-
-## Rollback Plan
-
-All changes are additive/defensive. If issues arise:
-1. Revert the edge store sync in `useSaveGraph.ts`
-2. Revert backend normalization (optional, only affects orphan cleanup)
-
-## Files Changed
-
-**Phase 1 (Critical):**
-- `autogpt_platform/frontend/src/app/(platform)/build/hooks/useSaveGraph.ts`
-
-**Phase 2 (Defense):**
-- `autogpt_platform/backend/backend/data/graph.py`
-
-**Phase 3 (Optional):**
-- `autogpt_platform/frontend/src/app/(platform)/build/hooks/useSaveGraph.ts` (query invalidation)
-
-## Open Questions
-
-1. **Is there a way to reproduce this consistently?** Need more info from Zamil about exact repro steps
-2. **Is AutoPilot creating agents differently?** The first screenshot suggests AutoPilot-created agents might have this issue more frequently
-3. **Are there existing graphs with orphan edges in prod?** May need a migration script to clean up
-
-## Estimation
-
-- Phase 1 (Frontend sync): 30 min
-- Phase 2 (Backend validation): 30 min  
-- Phase 3 (Cache invalidation): 15 min
-- Testing: 1 hour
-- **Total: ~2-3 hours**
-
-## Notes
-
-The core issue is likely that the frontend isn't syncing with the authoritative backend state after save. Phase 1 is the critical fix. Phases 2-3 are defensive measures.
