 ### Key Points
 
-- **Project Rules** are automatically loaded from `.qodeassist/rules/` directory structure
-- **System Prompts** are configured independently for each feature in Settings
-- **Agent Roles** add role-specific prompts on top of the base system prompt (Chat only)
-- **FIM vs Non-FIM models** for code completion use different System Prompts:
-  - FIM models: Direct completion prompt
-  - Non-FIM models: Prompt includes response formatting instructions
-- **Quick Refactor** has its own provider/model configuration, independent from Chat
+- **System Prompts** live in the agent's TOML profile (`system_prompt`); switch personas by switching agents
+- **Linked and open-synced files are always current**: their content is not stored in the conversation — every request re-reads the files and sends a fresh snapshot next to your latest message. Editing a linked file between messages never leaves a stale copy in the context, and changing it does not invalidate the provider's prompt cache for the whole conversation
+- **One-time attachments are different**: they are saved with the message they were sent with and stay in the history as sent
+- **FIM vs Non-FIM** for code completion is the agent's choice: a FIM agent renders prefix/suffix into native FIM fields, an instruct agent sends a chat-shaped request — pick the agent that matches your model
+- **Quick Refactor** has its own agent roster, independent from Chat
 - **Custom Instructions** provide reusable templates that can be augmented with specific details
-- **Tool Calling** is available for Chat and Quick Refactor when enabled
+- **Tool Calling** is available for Chat and Quick Refactor when the agent enables it; tool rounds per request are limited (configurable in `Settings → Tools`)

+New provider/model presets are plain TOML — extend a provider base, register the file in `agents.qrc`, and the test suite validates it automatically. Step-by-step guide: [docs/creating-agents.md](docs/creating-agents.md#contributing-your-agent-to-qodeassist).
