This week was hardening, not release-day fireworks.
Yaw Labs shipped the two practitioner books that have been in the pipeline since winter - Claude Code in Production and MCP in Production, both out Friday - and the new Yaw Forum went live as the post-Discord-ban home for support, tips, and showcases. Claude Code's four releases this week were operational rather than featureful. 2.1.126 finally accepts pasted OAuth codes when the browser callback can't reach localhost - the SSH, WSL, and devcontainer crowd has been waiting for this. Mac sleep no longer kills resumed sessions. A managed-settings sandbox bypass got patched. The model race itself was quiet - no new flagship since Opus 4.7 (Apr 16) and GPT-5.5 (Apr 23) - and the broader week's signal was Affinity launching a hosted MCP server for private capital, continuing the pattern of real apps shipping their own MCP rather than waiting for a generic adapter.

From the Yaw blog
- Claude Code in Production is out - twelve chapters on the discipline overlay around the model: contracts, memory, permissions, the failure modes that aren't model quality
- MCP in Production is out - fourteen case studies on schema, auth, hosting, security; the parts the spec and tutorials don't cover
- Yaw Forum is live - self-hosted Discourse at forum.yaw.sh, post-Discord-ban

The broader week
- Affinity hosted MCP server (Apr 28) - private-capital CRM exposes deal and relationship data to Claude, Gemini, Copilot via MCP; two-way reads and writes; the "real apps now ship their own MCP" pattern continues
- Codex Memory + Computer Use - OpenAI's desktop Codex now operates Mac apps with its own cursor in parallel, remembers preferences and recurring workflows across sessions, and added 90+ plugins combining skills + MCP servers; the agentic-loop space is consolidating around persistent state and OS-level tool access on both sides of the model fence
- Agentic AI Foundation - the Linux Foundation's AAIF (formed Dec 2025, anchored by MCP, goose, and AGENTS.md) crossed 170 member organizations including AWS, Anthropic, Bloomberg, Cloudflare, Google, Microsoft, OpenAI; the MCP server registry is at 9,400+ servers with 18% month-over-month growth
