Flue launches TypeScript agent harness framework

This is a credible shot at the layer most agent stacks are missing: not just the model loop, but the harness around it. If Flue gets traction, it could become infrastructure for teams that want agent behavior they can actually control, ship, and audit.

• –The emphasis on harness, sandbox, and session state is the right abstraction for serious agent workflows, especially coding and operations tasks
• –Built-in deployment targets like CLI, HTTP, and CI make it easier to operationalize agents instead of treating them as demos
• –The skills/session model maps well to how strong coding agents already work, which should make adoption feel familiar to developers
• –The category is crowded, so Flue will need a real ecosystem and clear differentiators beyond “another agent SDK”
• –Its strongest angle is control: teams can own the agent logic, execution environment, and tool boundaries end to end
