 - **Context & Token Visualization:** Detailed UI panels for monitoring real-time token usage, history depth, and **visual cache awareness** (tracking specific files currently live in the provider's context cache).
 - **On-Demand Definition Lookup:** Allows developers to request specific class or function definitions during discussions using `@SymbolName` syntax. Injected definitions feature syntax highlighting, intelligent collapsing for long blocks, and a **[Source]** button for instant navigation to the full file.
 - **Manual Ticket Queue Management:** Provides a dedicated GUI panel for granular control over the implementation queue. Features include color-coded priority assignment (High, Medium, Low), multi-select bulk operations (Execute, Skip, Block), and interactive drag-and-drop reordering with real-time Directed Acyclic Graph (DAG) validation.
+- **System Prompt Presets:** Comprehensive management system for saving and switching between complex system prompt configurations.
+  - **Scoped Inheritance:** Supports **Global** (application-wide) and **Project-Specific** presets. Project presets with the same name automatically override global counterparts, allowing for fine-tuned context tailoring.
+  - **Full AI Profiles:** Presets capture not only the system prompt text but also critical model parameters like **Temperature**, **Top-P**, and **Max Output Tokens**.
+  - **Preset Manager Modal:** A dedicated high-density GUI for creating, editing, and deleting presets with real-time validation and instant application to the active session.

 - **src/paths.py:** Centralized module for path resolution, allowing directory paths (logs, conductor, scripts) to be configured via `config.toml` or environment variables, eliminating hardcoded filesystem dependencies.
 
+- **src/presets.py:** Implements `PresetManager` for high-performance CRUD operations on system prompt presets stored in TOML format (`presets.toml`, `project_presets.toml`). Supports dynamic path resolution and scope-based inheritance.

 - **tree-sitter / AST Parsing:** For deterministic AST parsing and automated generation of curated "Skeleton Views" and "Targeted Views" (extracting specific functions and their dependencies). Features an integrated AST cache with mtime-based invalidation to minimize re-parsing overhead.
 - **pydantic / dataclasses:** For defining strict state schemas (Tracks, Tickets) used in linear orchestration.
 - **tomli-w:** For writing TOML configuration files.
