+# Implementation Plan
+
+## Phase 1: Fix Tool Preset Manager Crashes
+- [ ] Task: Investigate `render_tool_preset_manager_content` in `src/gui_2.py` to identify the missing `current_cat_tools` initialization or scope.
+- [ ] Task: Fix the `NameError` and ensure correct ImGui child window scoping (`EndChild` vs `End`) in the Tool Preset Manager.
+- [ ] Task: Conductor - User Manual Verification 'Fix Tool Preset Manager Crashes' (Protocol in workflow.md)
+
+## Phase 2: Fix Discussion Hub Crashes
+- [ ] Task: Investigate `render_discussion_entries` in `src/gui_2.py` to address the `IndexError` when deleting a discussion entry during rendering.
+- [ ] Task: Fix the `IndexError` (e.g. by deferring deletion or copying the list) and associated ImGui scoping errors (`PopID() too many times!`).
+- [ ] Task: Conductor - User Manual Verification 'Fix Discussion Hub Crashes' (Protocol in workflow.md)
+
+## Phase 3: Global Verification
+- [ ] Task: Run `python scripts/check_imgui_scopes.py` to statically verify all ImGui scopes are correct across the codebase.
+- [ ] Task: Run automated test suite to ensure no regressions were introduced.
+- [ ] Task: Conductor - User Manual Verification 'Global Verification' (Protocol in workflow.md)

+# Specification: Fix GUI Crashes in Tool Preset Manager and Discussion Hub
+
+## Overview
+This track addresses several critical crashes in the immediate-mode GUI (`gui_2.py`) related to the Tool Preset Manager and the Discussion Hub. These issues include Python exceptions (`NameError`, `IndexError`) and underlying ImGui rendering assertion failures (`PopID() too many times`, `Must call EndChild() and not End()!`).
+
+## Functional Requirements
+- **Tool Preset Manager Fixes:**
+  - Resolve the `NameError: name 'current_cat_tools' is not defined` when interacting with or modifying tool preset entries (e.g., changing approval from "auto" to "ask").
+  - Fix the ImGui scope mismatch (`Must call EndChild() and not End()!`) in the `tp_scroll_2FED8981` child window.
+- **Discussion Hub Fixes:**
+  - Resolve the `IndexError: list index out of range` in `render_discussion_entries` that occurs when deleting a discussion entry.
+  - Fix the associated ImGui scope mismatches (`Calling PopID() too many times!`) in the `HistoryChild_AB39D74A` window and tabs that trigger after the exception occurs.
+
+## Non-Functional Requirements
+- **ImGui Scope Safety:** Ensure all ImGui push/pop and begin/end pairs are correctly matched, even when exceptions are raised or lists are modified during rendering. The use of `imscope` context managers should be verified.
+- **Code Style:** Fixes must adhere to the 1-space indentation rule for Python code and follow the "ImGui Defer Patterns" described in the code style guides.
+
+## Acceptance Criteria
+- [ ] Modifying a tool preset (e.g., changing the approval status of `ts_cpp` tools) does not raise a `NameError` or crash the application.
+- [ ] Deleting a discussion entry removes the entry visually and does not raise an `IndexError`.
+- [ ] Both panels can be interacted with, opened, and closed without triggering ImGui assertion failures.
+- [ ] The `scripts/check_imgui_scopes.py` linter passes without new errors.
+
+## Out of Scope
+- Adding new features to the Tool Preset Manager or Discussion Hub.
+- General refactoring of the GUI outside of fixing these specific crash points.
