Microsoft and Hugging Face released ThinkingBox, an agent benchmark that grades terminal backend state and side effects rather than final responses or tool-call validity.
Why it matters: The paper's 20-run repeat metric and failure breakdown show why a clean tool-call trace can still leave the wrong database state.
Anthropic opened a directory submission portal for Claude plugins, which package MCP connectors.
Why it matters: Anthropic lays out the plugin packaging and submission path, so developers can see how a connector or skill becomes a listed extension.
GitHub Security Lab released the Fuzzing Taskflow, an autonomous fuzzing pipeline for C/C++ projects built on its Taskflow Agent framework. Pointed at a GitHub owner/repo slug.
Why it matters: The post details how the agent splits judgment from execution across MCP tools, useful for anyone building autonomous security pipelines.
Anthropic released three beta features on the Claude Developer Platform: Tool Search Tool.
Why it matters: The post gives the token and accuracy numbers behind three tool-use features, so readers can judge which bottleneck in their own agent setup each one addresses.
Anthropic Engineering describes presenting MCP servers as code APIs instead of direct tool calls.
Why it matters: Anthropic's own walkthrough of turning MCP servers into code APIs, with the token math and the sandboxing tradeoff spelled out.
Anthropic introduced Agent Skills, folders of instructions.
Why it matters: Anthropic's own account of how Agent Skills load context in layers, useful for anyone packaging agent expertise.
