What problem does it solve? Changing Mixdog configuration—models, workflows, MCP servers, plugins, skills, profiles, and Desktop appearance—requires knowing which settings domain applies and which mutation is supported. This Skill routes each request to the correct setup action, enforces approval and secret-handling boundaries, and verifies changes through mutation receipts instead of guessing. ## Core Features & Use Cases - Domain-scoped inspection and mutation: Read one status domain (model, agents, workflow, MCP, skills, plugins, memory, desktop, and more), then apply partial updates that preserve omitted fields. - Safe credential handling: API keys, OAuth tokens, and sign-ins are never passed through tool arguments; the Skill opens the Providers UI surface for user-operated authentication. - Receipt-based verification: Mutation results report saved state, scope, appliesTo, and appliedToCurrentSession so changes are confirmed rather than assumed. - Use Case: A user asks to switch the Web Search model and disable an unused MCP server. The Skill inspects the websearch and MCP status domains, applies set_web_search_route and set_mcp_enabled, and reports exactly what persisted and when it takes effect. ## Quick Start Ask the assistant to show the current model and workflow settings, then change the main model route to a different provider using the setup tool.
