Flue 2 Adds React-style Agent Hooks
Fred Schott, creator of the Astro web framework, has released Flue 2 — the first stable release of his agent framework — built around React-style "Agent Hooks" authored in TypeScript. Flue 2 provides 16 built-in hooks (including useSkill, useTool, useSubagent), a harness-based architecture for hosted agents, and is built on top of the open-source Pi harness. Schott positions Flue as an open-source, host-portable framework (while noting competitive overlap with Vercel’s eve), and says Flue leverages Cloudflare tooling after Astro’s acquisition by Cloudflare earlier in 2026.
Release of a stable, hook-based agent framework (Flue 2) introduces a composable developer model for AI agents and a harness-first architecture; relevant for teams building conversational agents and host-portable agent deployments, but not a major platform policy or industry-altering announcement.

Key Takeaways & Evidence Grounding
- Flue 2 was released as the first stable release and introduces React-style "Agent Hooks".
- Flue 2 includes 16 built-in hooks (examples: useSkill(), useTool(), useSubagent()) and supports custom hooks; hooks are authored in TypeScript.
- Fred Schott (creator of Astro) built Flue and his company Astro was acquired by Cloudflare in January 2026.
- Flue is built on top of the open-source Pi harness (pi.dev) and hosted agents in Flue 2 use Vite as the build tool.
- Vercel’s eve is identified as the closest competitive comparison; Flue emphasizes an opinionated, harness-integrated approach and host portability.

AI Agents That Build Their Own Tools Face Real Friction
A developer post describes Flowork, an open-source AI agent framework that can discover and generate its own tooling via capabilities like tool_search and tool_create. The author outlines operational issues encountered in practice — idempotency failures, registry growth and latency, security/autonomy trade-offs, and brittle dependency handling — and explains that Flowork represents tools as nodes in a Twin-Graph Brain. The tool_create logic is public on GitHub, roughly 1.5 years old, and currently has no active pull requests for its core agent-evolution code; the author invites senior developers and security researchers to review and improve the orchestration layer.
Cloudflare launches Kitesurf: browser for AI agents
Cloudflare has launched Kitesurf, a cloud-hosted browser built specifically for AI agents rather than human users. The browser runs entirely on Cloudflare Workers and is available free in beta via Browser Run, enabling developers to programmatically control headless browser instances to navigate sites, fill forms, and perform other agentic tasks. Cloudflare says Kitesurf was developed in roughly 12 weeks, is more CPU- and memory-efficient than Chromium for common agent tasks, and already passes roughly 215,000 web platform tests. The project combines several open-source technologies (a modular Blitz renderer, Firefox’s Stylo CSS parser, Boa JS) and was inspired by the Obscura Rust headless engine.
Agent-First Coding Tools and Agent Infrastructure Surge
A Latent Space AINews roundup (published 2026-05-15) summarizes a wave of agent-first coding tooling and agent infrastructure updates. Major product moves include GitHub’s Copilot App technical preview and OpenAI integrating Codex into the ChatGPT mobile app (with Remote SSH, hooks, and programmatic tokens). LangChain released SmithDB and the LangSmith Engine and announced LangChain Labs to operationalize continual learning from production agent traces. Anthropic tightened Claude Code usage, prompting developer backlash and subscription cancellations. Robotics firm Figure livestreamed 24+ hours of autonomous sorting on Helix-02. The issue also highlights research/model releases (Zyphra diffusion LM preview, Datadog’s Toto 2.0 time‑series models) and discussions about agent orchestration, execution isolation, and the evolving economics of subscription-backed agent workflows.
