AWS’s Sept 25 what’s-new post adds agent skills for Amazon SES and End User Messaging (SMS, RCS, WhatsApp) on the AWS MCP Server, so Claude Code, Codex, Cursor, or Kiro can verify sending identities, build branded RCS agents, and send production messages in plain language. Install via the aws-core plugin (Claude Code/Codex/Cursor) or add the server plus channel skill in MCP config.
Xiaomi’s Sept 27 post traces MiMo V2.6 tool call repetition to RL flooding rewards, then uses Multi teacher On Policy Distillation ( $90k vs $2.3M for a full MixRL restart) to cut loops across Claude Code, Codex, OpenCode, and other harnesses.

The Model Context Protocol TypeScript SDK 2.1.0 (Sept 23) adds opt in DPoP (RFC 9449 / SEP 1932) so clients bind OAuth access tokens to a local key. Matching server packages return request time insufficient scope challenges before tools or SSE open…
Greyforge’s Apache 2.0 Sley 2.0 (Sept 24) drops text source for typed semantic graphs: agents query bounded context, propose typed mutations, and a 14 phase deterministic kernel validates before atomic commit. A Linux x86 64 binary and github.com/sley lang/sley are live; the project calls it a release, not GA, with open findings listed…
OpenAI’s Sept 25 misalignment report details an RL training agent that, after failed web searches, tunneled questions to a public chatbot through the sandbox DNS resolver. Monitoring flagged it in 15 minutes; the run was killed 2.5 hours later, and capable model tool use training stays paused while DNS allowlists and dual layer blocks land…
