# Specification: Saved System Prompt Presets

## Overview
This feature introduces the ability to save, manage, and switch between system prompt presets for both global (application-wide) and project-specific contexts. Presets will include not only the system prompt text but also model-specific parameters like temperature and top_p, effectively allowing for "AI Profiles."

## Functional Requirements
- **Dedicated Storage:**
    - Global presets: Stored in a global `presets.toml` file (located in the application configuration directory).
    - Project presets: Stored in a `project_presets.toml` file within the project's root directory.
- **Preset Content:**
    - `name`: A unique identifier for the preset.
    - `system_prompt`: The text of the system prompt.
    - `temperature`: (Optional) Model temperature setting.
    - `top_p`: (Optional) Model top_p setting.
    - `max_output_tokens`: (Optional) Maximum output tokens.
- **Inheritance & Overriding:**
    - The UI will display a unified list of global and project-specific presets.
    - If a project-specific preset has the same name as a global one, the project-specific version will override it.
- **GUI Interactions:**
    - **Settings Dropdown:** A dropdown menu in the "AI Settings" (global) and "Project Settings" (per-project) panels for quick switching between presets.
    - **Preset Manager Modal:** A dedicated modal accessible from the settings panels to create, edit, and delete presets.
    - **Auto-Loading:** Switching a preset in the dropdown will immediately update the active system prompt and associated model parameters in the AI client configuration.

## Non-Functional Requirements
- **Persistence:** All changes made in the Preset Manager must be immediately persisted to the corresponding `.toml` file.
- **Validation:** Ensure preset names are unique within their scope (global or project).
- **Concurrency:** Ensure safe file access if multiple windows or instances are open (though Manual Slop is primarily single-instance).

## Acceptance Criteria
- [ ] Users can create a new global preset and see it in the dropdown across all projects.
- [ ] Users can create a project-specific preset that is only visible when that project is active.
- [ ] Overriding a global preset with a project-specific one (same name) correctly loads the project version.
- [ ] Changing a preset via the dropdown updates the active AI configuration (prompt, temperature, etc.).
- [ ] The Preset Manager modal allows for full CRUD (Create, Read, Update, Delete) operations on presets.

## Out of Scope
- Support for other file formats (e.g., JSON, YAML) for presets.
- Presets for specific files or folders (scoped only to global or project level).
- Cloud syncing of presets.
