Astro creator Fred Schott releases Flue 2, bringing React-style hooks to agent development

React for Agents: Astro Creator Brings Hooks to his Meta-Harness, Flue

Flue 2 is the first stable release of Fred Schott's agent framework, built around 16 React-style Agent Hooks authored in TypeScript. Hooks let agents dynamically attach tools, skills, and subagents as a conversation or workflow unfolds, rather than requiring upfront static configuration. Schott says this is necessary for real support and triage bots. Flue 2 runs on the open-source harness Pi and uses Vite for hosted agents. After seeing enterprise users run a single company-wide agent, Schott dropped file-based routing in favor of React-like composability.

Why it matters: Astro creator Fred Schott brings React Hooks into agent frameworks with 16 TypeScript hooks for runtime tool/sub-agent mounting—useful for teams building customer service or triage bots. Capped at 72 because Flue is still a niche open-source project with no large-scale adoptio...

This one's worth opening because of who built it: Fred Schott, the creator of Astro (acquired by Cloudflare). He's now applying React's composability model to agent frameworks with Flue 2. The core is 16 TypeScript Agent Hooks — useSkill(), useTool(), useSubagent() — that let agents dynamically attach capabilities as a conversation unfolds, rather than requiring everything to be wired up front. Schott says this is necessary for real support and triage bots where you can't pre-configure every scenario.

The other interesting bit: he initially ported file-based routing from web frameworks into Flue, then dropped it after seeing enterprise users run a single company-wide agent. That's a practical pivot — the framework is being shaped by actual usage, not web dev assumptions.

Flue 2 runs on the open-source harness Pi and uses Vite for hosting. I'd treat it as a lightweight agent orchestration layer for TypeScript devs — not a LangChain-scale kitchen sink, but the Hook abstraction is genuinely more flexible than static tool lists.
