Claude Code is Anthropic's command-line (and now desktop/web) agent that drives real work end-to-end: it edits code, runs tests, calls tools and MCP servers, and acts on a connected vault or repo. Simon Willison calls the launch of Claude Code (with Sonnet 3.5) "the killer moment" — the first agent good enough to usefully drive a terminal — and a year on he writes most of his code through it, often from his phone via claude-code-for-web. In the creator scene it's used far beyond coding: as a personal automation hub wired into MCPs (image generation, content, scheduling) to run repeatable business workflows. Kept (not demoted) because it's a genuine workhorse tool with deep, non-obvious workflows — distinct from the claude model itself.
Treat Claude Code as the default engine for every build + automation, not just coding — it's already the runtime OTTO operates on.
