Deep Agents Code now supports `/tools`, which lists the built-in and MCP tools available to the current agent. --- Adds an interactive `/tools` slash command to the `deepagents-code` TUI so users can see the tools available to the current agent, grouped into built-in tools and tools from each MCP server. MCP servers that are disabled, need login, or failed to load are shown separately instead of disappearing from the list. For managed sessions, built-in tools are enumerated off the UI thread with a credential-free agent compile. For preconfigured local agents, `/tools` inspects the active graph directly so custom tool sets remain authoritative. When a custom or remote agent cannot be inspected, the command explains that limitation rather than incorrectly reporting that no tools are available. MCP entries reuse the metadata loaded for the running agent instead of starting discovery inside Textual's live event loop. If `/mcp` configuration changes are waiting for a reconnect, `/tools` keeps using the pre-change snapshot so its output continues to match the tools the agent can currently invoke. The catalog is rendered as a chat message, like `/tokens`, and is discoverable through `/help`, command completion, and a startup tip.
