Browser vendors ship a skill pack for coding agents, with evals attached

Modern Web Guidance is a set of agent skills and a local CLI. The agent searches about 200 hand-written guides on current HTML, CSS and browser APIs and loads the matching guide into its context.

AWS puts each agent workload in its own Nitro VM, at no extra charge

AWS made Nitro Sandboxes available. They are lightweight VMs managed by the Nitro Hypervisor, and each EKS pod, ECS task or VM that uses one gets its own hardware isolation boundary on a shared EC2 instance.

Agents modelled 15.7% of CPython in Lean, found 418 bugs, and showed that correct proofs can check nothing

Andrews and Zhang pointed Opus 5.5 at CPython 3.15.2 and had agents copy its functions into Lean line by line. Each function goes through four steps: copy the source, test the copy against real Python on at least 50,000 inputs, prove or…

DeepMind reports agents formally verified Signal's protocol code, with humans reviewing the specifications

DeepMind describes AlphaProof Code as a multi-LLM agentic framework in which human experts and AI decide what to prove and a group of agents does the proving. Its researchers worked with models to turn Signal's security goals into formal…

Meta ships Muse Ember, a $0.10 and $0.50 per million token model aimed at subagent work

Meta lists muse-ember-1.0 at $0.10 per million input tokens and $0.50 per million output tokens for prompts up to 200K tokens, with a 1M-token context window and up to 512K output tokens. Meta says it matches Claude Haiku 5.5's best…

AWS reports replacing Sonnet 4.6 with a small decision model for ticket labeling, after a dual-run rollout

Two Amazon engineers swapped Claude Sonnet 4.6 for Strands Decider, a model that returns a probability for each option in a fixed list instead of generating text, on an internal ticketing system with 20 label categories. They report average…

A Rust build cache for agent worktrees reports 9.3 seconds against Cargo's 3 min 42 s

Panasenko, who built the Mitts build tool, reports that a parallel build of 12 rustls worktrees on Linux x86_64 took 3 min 42 s with plain Cargo and 9.3 s with Mitts. Cargo with a warm sccache took 3 min 59 s.

ZTHR proposes a pattern language where gates replace human diff review

Little's executive summary argues that AI has made writing code cheap but has not made deciding whether it is right cheaper, and that human review under real volume becomes either a bottleneck or a rubber stamp. His answer is a factory of…

Anthropic details how 1,000 agents coordinated through Git and Postgres

Anthropic describes what it calls a toy experiment in which 1,000 agents running an early version of Fable 5.2 reproduced a formal proof of Fermat's Last Theorem. The team took 28.7 hours, used one-third as many output tokens and wrote a…

A new benchmark holds the model fixed and swaps the harness

The repository holds Opus 5.5 and a set of 20 public multi-user tasks fixed and changes only the harness. On Opus 5.5, pass rates were QM 72.5%, Claude Code 76.3%, Hermes Agent 78.8% and OpenClaw 76.3%, and no tested pair could be told…

CodeRabbit scales agentic software development and ships 20x more

An OpenAI-published interview with CodeRabbit CEO Harjot Gill, who says the company has shipped roughly 20 times more software over six months with the same team using Codex. He says the first bottleneck after adopting coding agents is code…

Anthropic ships Fable 5.2 cheaper than 5.1, and says 1,000-agent runs now finish large builds

Anthropic says Fable 5.2 and Mythos 5.2 are the same underlying model. Fable carries cyber and biology safeguards and is available to everyone as claude-fable-5-2; Mythos is open by application through Anthropic's verification programs.

Epic ships an Unreal Engine preview it says was built mainly by directed agent fleets

Epic describes the release as "the first Unreal Engine release built primarily with agentic workflows." Per the announcement, a handful of people directed fleets of agents to port AI tooling from the UE6 development branch and to add the…

A kernel built in eleven days by one agent task, then set aside by its author

Kurtzer's report describes what he calls Human-Directed Agentic Engineering. The human defines architecture, constraints, milestones, acceptance criteria and stopping points.

A leaderboard puts five harnesses in a statistical tie on open models

The leaderboard runs nine harnesses on three open-weight models (GLM-5.3-Flash, DeepSeek-V4.1-Flash and Flint) across Terminal-Bench 2.1 and DeepSWE v1.1. Each harness gets the same model, provider and reasoning effort, three attempts per…

Dependabot now opens pull requests for agent skills and prompts

GitHub says you can now keep "AI agent skills, prompts, and instructions" up to date with Dependabot version updates for Agent Package Manager (APM). Dependabot opens pull requests to update supported git dependencies declared in apm.yml…

GitHub Agentic Workflows is generally available
