I've added a tree view to pick files in Toad. 🐸
Fuzzy searching is great when you know what you're looking for. But a tree view is more natural when you want to look through your files.
Toad is a unified interface for agentic coding, and all things AI, in your terminal.

Vercel AI SDK 6 is official released. The details are on vercel.com/blog/ai-sdk-6
The feature I prefer is the Tool Improvements and the needsApproval option that allows to force user approval on the first tool usage.
OAuth for MCP is also awesome feature.

Datalayer is joining the AgentX AgentBeats challenge! 🥊
To benchmark our data agent, we "agentified" DABench using the A2A protocol. The setup uses Pydantic AI and our Jupyter MCP Server.
We think A2A + MCP is the future of agent interoperability. 🤝

@willmcgugan.bsky.social (creator of Rich/Textual) — super promising approach to connecting local & remote agents. A few UX bumps (SPACE to start chat not obvious, needed restarts), but overall excited.
