Anomalithic is a premium harness around any model: a swarm of specialists, real tools, durable sessions, MCP, and a trace you can watch think. An Orchestrator plans and delegates; specialists run in parallel, call tools, and hand off; every thinking window mints a signed impression (the trust anchor for a thinking-time ad layer, kept as a placeholder in v1).

Provider-agnostic agent loop — gather → think → act → observe, with agent-defined thinking windows that mint signed impressions on any model.

Free Models Router — zero-cost default that routes around rate-limited free OpenRouter models; plus Anthropic, OpenAI, Gemini, Ollama, and a Mock provider.

Multi-agent swarm — an Orchestrator + 8 specialists (Researcher, Coder, Analyst, Writer, Slides, Docs, Image, Video) with delegate, delegate_parallel, and handoff.

Real tools — path-confined fs, guarded shell, web_fetch, plus MCP servers exposed as agent tools (official MCP SDK).

Durable sessions + permission rulesets (subagent narrowing).

Local runtime API — serve streams the trace as SSE; a typed SDK consumes it.

Premium UI — a Next.js web app (live swarm console, design system, motion) and a Tauri desktop shell rendering the same UI.
