 ## Key Systems
 
+### 0. Task 2 Completion Summary
+
+**Task 2 has been completed successfully (12/12 tasks done)!**
+
+Key changes made in Task 2:
+- **ActionButtons Rework**: Removed manual selection, auto-transition to Meditate after actions
+- **SpireTab Overhaul**: Added "Climb the Spire" button, implemented Spire Mode with exit condition
+- **Equipment System**: Added support for 2-Handed Weapons, Staves now block offhand slot
+- **Research Locking**: Prevent switching topics while study in progress
+- **DebugTab Update**: Added Invoker Debugging Buttons for Pacts
+- **Combat UI Fix**: Fixed Casting Bar progress animation
+- **Crafting Limits**: Disabled Prepare for non-enchanted items, limited Design to owned gear types
+- **System Integrity**: Fixed Show Component Names debug option for all components
+- **StatsTab**: Locked Fire/Water/Air/Earth at start, only Transference unlocked
+- **LootTab**: Removed Transference from essence list (not lootable)
+- **Ascension Skills**: Deleted all Ascension skills
+- **Mana Well Fix**: Fixed Deep Basin upgrade multiplier values
+
+**Context File Approach for Sub-Agents:**
+During Task 2, context files were created in `docs/` to guide sub-agents:
+- `update_agents_context.md` - Context for updating AGENTS.md
+- `update_game_briefing_context.md` - Context for updating GAME_BRIEFING.md  
+- `update_skills_context.md` - Context for updating skills.md
+
+This approach proved effective for delegating documentation updates to sub-agents.
+
 ### 1. State Management (`store.ts`)
 
 The game uses a Zustand store organized with **slice pattern** for better maintainability:
 
 #### Store Slices
-- **Main Store** (`store.ts`): Core state, tick logic, and main actions
-- **Navigation Slice** (`navigation-slice.ts`): Floor navigation (setClimbDirection, changeFloor)
-- **Study Slice** (`study-slice.ts`): Study system (startStudyingSkill, startStudyingSpell, cancelStudy)
-- **Crafting Slice** (`crafting-slice.ts`): Equipment/enchantment (createEquipmentInstance, startDesigningEnchantment)
-- **Familiar Slice** (`familiar-slice.ts`): Familiar system (addFamiliar, removeFamiliar)
+- **Main Store** (`store.ts`): Core state, tick logic, and main actions (~2812 lines)
+- **Navigation Slice** (`navigation-slice.ts`): Floor navigation (setClimbDirection, changeFloor) (~75 lines)
+- **Study Slice** (`study-slice.ts`): Study system (startStudyingSkill, startStudyingSpell, cancelStudy) (~210 lines)
+- **Crafting Slice** (`crafting-slice.ts`): Equipment/enchantment (createEquipmentInstance, startDesigningEnchantment) (~1100 lines)
+- **Familiar Slice** (`familiar-slice.ts`): Familiar system (addFamiliar, removeFamiliar) - **NOTE: File does not currently exist**
 
 #### Computed Stats (`computed-stats.ts`)
 Extracted utility functions for stat calculations:

 ### Existing Slices
 
-| Slice | File | Purpose |
-|-------|------|---------|
-| Navigation | `navigation-slice.ts` | Floor navigation (setClimbDirection, changeFloor) |
-| Study | `study-slice.ts` | Study system (startStudyingSkill, startStudyingSpell, cancelStudy) |
-| Crafting | `crafting-slice.ts` | Equipment/enchantment (createEquipmentInstance, startDesigningEnchantment) |
-| Familiar | `familiar-slice.ts` | Familiar system (addFamiliar, removeFamiliar) |
+| Slice | File | Lines | Purpose |
+|-------|------|-------|----------|
+| Navigation | `navigation-slice.ts` | ~75 | Floor navigation (setClimbDirection, changeFloor) |
+| Study | `study-slice.ts` | ~210 | Study system (startStudyingSkill, startStudyingSpell, cancelStudy) |

 ## File Size Guidelines
 
-### Current File Sizes (After Refactoring)
-| File | Lines | Notes |
-|------|-------|-------|
-| `store.ts` | ~1650 | Core state + tick logic (reduced from 2138, 23% reduction) |
-| `page.tsx` | ~1695 | Main UI (reduced from 2554, 34% reduction) |
-| `computed-stats.ts` | ~200 | Extracted utility functions |
-| `navigation-slice.ts` | ~50 | Navigation actions |
-| `study-slice.ts` | ~100 | Study system actions |
+### Current File Sizes (After Task 2)
+| File | Lines | Size (bytes) | Notes |
+|------|-------|--------------|-------|
+| `store.ts` | ~2812 | ~103KB | Core state + tick logic, crafting-slice extracted |
+| `page.tsx` | ~548 | ~22KB | Main UI (heavily reduced through component extraction) |
+| `crafting-slice.ts` | ~1100 | ~35KB | Equipment/enchantment logic (extracted from store.ts) |
+| `skill-evolution.ts` | ~3400 | ~120KB | Skill tier progression paths |
+| `study-slice.ts` | ~210 | ~8KB | Study system actions |
+| `navigation-slice.ts` | ~75 | ~3KB | Navigation actions |
+| `computed-stats.ts` | ~12 | ~1KB | Extracted utility functions (some moved to slices) |
+| `components/game/tabs/*.tsx` | ~3000 | ~95KB | Tab-specific components (SpireTab, CraftingTab, etc.) |
 
 ### Guidelines
-- Keep `page.tsx` under 2000 lines by extracting to components (ActionButtons, ManaDisplay, etc.)
-- Keep `store.ts` under 1800 lines by extracting to slices (navigation, study, crafting, familiar)
-- Extract computed stats and utility functions to `computed-stats.ts` when >50 lines
+- Keep `page.tsx` under 600 lines by extracting to components (ActionButtons, ManaDisplay, tabs, etc.)
+- Keep `store.ts` under 3000 lines by extracting to slices (navigation, study, crafting, familiar)
+- Extract computed stats and utility functions to appropriate slices or utils when >100 lines
 - Use barrel exports (`index.ts`) for clean imports
 - Follow the slice pattern for store organization (see below)
+- **After Task 2**: `page.tsx` reduced from ~2554 to ~548 lines (78% reduction)
+- **After Task 2**: `store.ts` increased due to crafting-slice integration, but better organized
