## TL;DR

- A Hacker News thread calls out the messy terminology in the AI agents ecosystem and proposes a cleaner taxonomy.

---

## Summary

- A Hacker News thread calls out the messy terminology in the AI agents ecosystem and proposes a cleaner taxonomy.
- The author suggests three layers: Harnesses (UI + system prompts + tools wrapped around an LLM, e.g. Claude Code, Gemini CLI), Gateways (connectors to communication platforms like WhatsApp or Slack), and Sandboxes (isolated, auditable runtime environments).
- The core complaint: almost everything gets labeled 'Agent', even products that only implement one narrow slice of the stack.
- The thread explores whether terms like 'Orchestrator' or 'Runner' would be more precise and where the real architectural boundaries sit.

## Nauti's Take

The thread is symptomatic of a broader problem: the AI industry names things for marketing value, not technical function, then acts surprised when nobody can orient themselves. The proposed three-way split – Harness / Gateway / Sandbox – is pragmatic and immediately useful, even if still rough around the edges. What it misses is a dedicated category for true orchestration logic: the layer that coordinates multiple agents, manages state, and handles failures. Frameworks like LangGraph or Temporal belong there but barely get a mention. Until the industry converges on shared vocabulary, the only fix is doing your own layer-by-layer audit before buying into any 'agent' platform.
