Claude Code revenue runs at $2.5B annually with 4% of all GitHub commits. Anthropic is moving upstream into Platform: Claude Managed Agents (PaaS, $2.58 fulfillment cost per $1k service, Linear SDK), the Advisor Strategy (Opus advisor + Sonnet/Haiku executor as first-class pattern), Monitor tool (event-driven background scripts replacing polling), and official claude-code-setup plugin recommending hooks, skills, MCPs, subagents, automations. First-party documentation spans a 14-minute video guide and 33-page Skills guide. Skill distribution formalized: gstack packages dotfiles-for-AI, ByteRover unifies scattered knowledge into queryable index, claude-smart adds cross-project learning, self-improving skills grade against binary eval criteria. NVIDIA hosts ~80 free models via APIs (DeepSeek, Kimi, GLM). Enterprise adoption is real: Intercom built 13 plugins with 100+ skills, $1M+ customers 40x'd to 500+. GitHub plugin marketplace auto-installs across team instances. Evo (open-source) turns codebases into self-instrumenting research loops. Tolaria's MCP server lets Claude natively edit vaults (100K+ LOC, 85% test coverage). LibreChat's native MCP support extends ecosystem through self-hosted wrappers. Claude Ads audits 250+ checks, cuts waste 35%. Anthropic employees share internal methods for tracking Claude development publicly.
