AGENTS

Vercel just declared the agent stack: AI Gateway, Sandbox, Flags, and Microfrontends. Here is how the four primitives compose, with code, and where each one actually fits in a real product.

Durable execution lands on Vercel. What it means for agents, long-running flows, and indie dev stacks - with code, gotchas, and where it fits the agent stack.

Agent runs are opaque. TraceTrail turns a Claude Code JSONL into a public share link with a stepped timeline of messages, tool calls, and tokens.

The second half of our agent tooling release: distribution, validation, and ergonomics layered on top of the first six. Six small CLIs, one through-line.

DeepSeek's reasoning-first model built for agents. First model to integrate thinking directly into tool use. Ships alongside V3.2-Speciale, which rivals GPT-5 and Gemini 3.0 Pro.

Self-healing browser automation harness that lets LLMs complete any browser task. 5,000+ stars in under a week.

Headless browser built in Rust for controlled AI-agent browser tasks. Lighter and faster than Chromium-based alternatives.

Define custom subagent types within your project's memory layer.

Spawn isolated workers with independent context windows.
