 ### Tools & Function Calling
-- Read project files
+
-- List and search in project
+Chat and Quick Refactor can call tools to inspect and modify your project. Each tool can be individually enabled/disabled in settings.
-- Access linter/compiler issues
+
-- Enabled by default (can be disabled)
+| Tool | What it does |
+|------|--------------|
+| `list_project_files` | List files in the active project(s) |
+| `find_file` | Find a file by name or partial path |
+| `read_file` | Read file contents (project or absolute path) |
+| `search_project` | Grep / symbol search across project sources |
+| `create_new_file` | Create a new empty file on disk |
+| `edit_file` | Replace content in a file (old → new) |
+| `build_project` | Build the active project and return compiler output |
+| `get_issues_list` | Read current linter / compiler diagnostics |
+| `execute_terminal_command` | Run a shell command (with confirmation) |
+| `todo_tool` | Track multi-step task progress during a conversation |
+
+### 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.
+
+- **Enable** in `Tools → Options → QodeAssist → MCP Server`
+- **Transport**: HTTP + SSE by default; a stdio bridge is provided for clients that only speak stdio (e.g. Claude Desktop)
+- **Ready-to-copy snippets** for Claude Code, VS Code, and the bridge are available via the "Show connection instructions" button in settings
+
+### MCP Client Hub
+
+QodeAssist can also act as an **MCP client**, connecting to external MCP servers and making their tools available to Chat and Quick Refactor alongside the built-in ones.
+
+- **Configure** servers in `Tools → Options → QodeAssist → MCP Client`
+- **Transports**: stdio and HTTP/SSE
+- **Limitation**: authenticated MCP servers (OAuth / token-protected) are **not supported yet** — only servers that accept unauthenticated local connections work for now
