+### Skills
+
+**Agent Skills** package specialized instructions and workflows into reusable folders the AI loads on demand. QodeAssist implements the open [Agent Skills](https://agentskills.io) format, so skills authored for Claude Code, Cursor, or other agents work as-is.
+
+A skill is a folder containing a `SKILL.md` file — YAML frontmatter (`name`, `description`) plus Markdown instructions:
+
+```
+my-skill/
+└── SKILL.md
+```
+
+```markdown
+---
+name: my-skill
+description: What the skill does and when to use it.
+---
+
+# My Skill
+
+Step-by-step instructions for the task...
+```
+
+**Where skills are discovered:**
+- **Project skills** — project-relative subdirectories (default `.qodeassist/skills/` and `.claude/skills/`), configured in `Projects → QodeAssist → Skills`. Project skills win over global ones on a name collision.
+- **Global skills** — absolute directories shared across all projects (default includes `~/.claude/skills/`), configured in `Tools → Options → QodeAssist → Skills`.
+
+Both settings pages show the list of currently discovered skills.
+
+**How skills are used in Chat:**
+- **Automatically** — each skill's name and description is added to the system prompt; when a request matches, the model loads the full instructions via the `load_skill` tool (requires a tool-calling model).
+- **Explicitly** — type `/` in the chat input and pick a skill from the popup; its instructions are injected into that one message. Works with any model.
+- **Always-on** — a skill whose frontmatter has `metadata: always-on: "true"` is injected into every chat request automatically.
+
+Enable or disable the whole feature in `Tools → Options → QodeAssist → Skills`.
+
 ### MCP Server
 
 QodeAssist can run an **MCP (Model Context Protocol) server** on `localhost`, exposing the tools above to external clients — so you can use QodeAssist's project awareness from Claude Code CLI, VS Code, Cursor, Claude Desktop, or any other MCP-capable client.

- * REFERENCE: Item Types in List Input Items Response
- * ===================================================
- * 
- * The `data` array in ListInputItemsResponse can contain various item types.
- * This file serves as a reference for all possible item types.
- * 
- * EXISTING TYPES (already implemented):
- * -------------------------------------
- * - MessageOutput (in ResponseObject.hpp)
- * - FunctionCall (in ResponseObject.hpp)
- * - ReasoningOutput (in ResponseObject.hpp)
- * - FileSearchCall (in ResponseObject.hpp)
- * - CodeInterpreterCall (in ResponseObject.hpp)
- * - Message (in ModelRequest.hpp) - for input messages
- * 
- * ADDITIONAL TYPES (to be implemented if needed):
- * -----------------------------------------------
- * 
- * 1. Computer Tool Call (computer_call)
- *    - Computer use tool for UI automation
- *    - Properties: action, call_id, id, pending_safety_checks, status, type
- *    - Actions: click, double_click, drag, keypress, move, screenshot, scroll, type, wait
- * 
- * 2. Computer Tool Call Output (computer_call_output)
- *    - Output from computer tool
- *    - Properties: call_id, id, output, type, acknowledged_safety_checks, status
- * 
- * 3. Web Search Tool Call (web_search_call)
- *    - Web search results
- *    - Properties: action, id, status, type
- *    - Actions: search, open_page, find
- * 
- * 4. Image Generation Call (image_generation_call)
- *    - AI image generation request
- *    - Properties: id, result (base64), status, type
- * 
- * 5. Local Shell Call (local_shell_call)
- *    - Execute shell commands locally
- *    - Properties: action (exec), call_id, id, status, type
- *    - Action properties: command, env, timeout_ms, user, working_directory
- * 
- * 6. Local Shell Call Output (local_shell_call_output)
- *    - Output from local shell execution
- *    - Properties: id, output (JSON string), type, status
- * 
- * 7. Shell Tool Call (shell_call)
- *    - Managed shell environment execution
- *    - Properties: action, call_id, id, status, type, created_by
- * 
- * 8. Shell Call Output (shell_call_output)
- *    - Output from shell tool
- *    - Properties: call_id, id, max_output_length, output (array), type, created_by
- *    - Output chunks: outcome (exit/timeout), stderr, stdout
- * 
- * 9. Apply Patch Tool Call (apply_patch_call)
- *    - File diff operations
- *    - Properties: call_id, id, operation, status, type, created_by
- *    - Operations: create_file, delete_file, update_file
- * 
- * 10. Apply Patch Tool Call Output (apply_patch_call_output)
- *     - Output from patch operations
- *     - Properties: call_id, id, status, type, created_by, output
- * 
- * 11. MCP List Tools (mcp_list_tools)
- *     - List of tools from MCP server
- *     - Properties: id, server_label, tools (array), type, error
- * 
- * 12. MCP Approval Request (mcp_approval_request)
- *     - Request for human approval
- *     - Properties: arguments, id, name, server_label, type
- * 
- * 13. MCP Approval Response (mcp_approval_response)
- *     - Response to approval request
- *     - Properties: approval_request_id, approve (bool), id, type, reason
- * 
- * 14. MCP Tool Call (mcp_call)
- *     - Tool invocation on MCP server
- *     - Properties: arguments, id, name, server_label, type
- *     - Optional: approval_request_id, error, output, status
- * 
- * 15. Custom Tool Call (custom_tool_call)
- *     - User-defined tool call
- *     - Properties: call_id, input, name, type, id
- * 
- * 16. Custom Tool Call Output (custom_tool_call_output)
- *     - Output from custom tool
- *     - Properties: call_id, output (string or array), type, id
- * 
- * 17. Item Reference (item_reference)
- *     - Internal reference to another item
- *     - Properties: id, type
- * 
- * USAGE:
- * ------
- * When parsing ListInputItemsResponse.data array:
- * 1. Check item["type"] field
- * 2. Use appropriate parser based on type
- * 3. For existing types, use ResponseObject.hpp or ModelRequest.hpp
- * 4. For additional types, implement parsers as needed
- * 
- * EXAMPLE:
- * --------
- * for (const auto &itemValue : response.data) {
- *     const QJsonObject itemObj = itemValue.toObject();
- *     const QString type = itemObj["type"].toString();
- *     
- *     if (type == "message") {
- *         // Use MessageOutput or Message
- *     } else if (type == "function_call") {
- *         // Use FunctionCall
- *     } else if (type == "computer_call") {
- *         // Implement ComputerCall parser
- *     }
- *     // ... handle other types
- * }
