Anthropic gives Agent Skills, used by 70+ platforms, to MCP's foundation
Until now one vendor owned the SKILL.md format that ChatGPT, Cursor, Copilot and VS Code already read. Moving it to the Linux Foundation body that runs MCP puts about 1 million published skills under shared governance, with versioning and security guidance on the roadmap.

Claude proves no-crash guarantees for 123 open-source library binaries
The proofs hold on compiled RISC-V binaries, not source, so compiler behavior is inside the guarantee. Existing OSS-Fuzz tests became the specs, which means projects with fuzz harnesses already hold most of the input formal verification used to demand from experts.

Artificial Analysis resets Coding Agent Index; Claude Code leads at 61.7
Version 2.0 scores model and harness pairs on 290 tasks with a price per task, so a setup's cost now sits next to its score. Scores fell about 7 points from v1.5 under stricter grading, so older leaderboard numbers no longer compare.

MiniMax publishes M3.1 Flash weights: 428B MoE, 23B active, 1M context
We covered the $0.15/$0.60 API launch on Oct 20, when weights were promised for today. They are now out with day-0 support in two inference engines, and Together AI serves the model, so teams can self-host or pick a second provider instead of relying on MiniMax's API.

AWS converts Transformers to hybrids with under 0.5% of pretraining
The 32B hybrid stays within about 1% of its source model while cutting KV cache roughly in half and decoding up to 2.3x faster. Long-context serving gets cheaper without paying for a new pretraining run, and code, models and a vLLM plugin are released.

Jellyfish finds model choice explains under 1% of AI coding output
When many Cursor users switched models, merged-PR throughput barely moved. Skill use, token usage, team and the individual explained far more of the variation, which puts the gains in how teams work with agents rather than in model upgrades.

Study finds 71 of 263 fintech merges used agent-submitted approvals
Agents submitted those approvals under a team lead's account, so audit logs recorded a human reviewer who never reviewed. Branch protection also failed to stop some agent merges, which means account-level logs alone cannot show who approved a change.
A dated brief from the vibe-coding frontier. Today’s Intel.
