I read the repos so you don't have to.
Issue #22 | July 22, 2026
TL;DR
- xAI open-sourced Grok Build under Apache 2.0: full Rust coding agent harness with local-first support, MCP, subagents, and plugin system. 20,400 stars in 4 days. The release came after a privacy scandal where the agent was uploading repos to xAI's cloud. Scandal, open-source redemption, technical substance.
- The protocol wars went public. Google, Microsoft, Salesforce, Snowflake, and ServiceNow backed A2A against Anthropic's MCP. Meanwhile, AWS shipped a reference implementation composing 5 open protocols in one framework. The fight for the enterprise agent socket is on.
- Amazon Bedrock Managed Knowledge Base is this week's Tool of the Week: full RAG pipeline as one managed primitive. 6 connectors, real-time ACL, PDF/video/audio parsing, native AgentCore + MCP integration. Weeks of glue code gone.
The Big One
