One comment ID. A focused next step. Illustrated explainer. Synthetic English narration. Conceptual examples; no recorded live agent execution. Precise feedback becomes more useful when it travels with the work. Start with one comment in your local project. Give your existing Codex or Claude session its ID and a bounded instruction: check the evidence, revise this section, and explain the change. The authorized agent retrieves the feedback and reads the relevant source. A browser comment alone does not start an agent. The file is revised outside the browser, and the agent replies to the same conversation. The question stays connected to the response. Back in Review with AI, inspect the changed passage and explanation. A reply, or a repaired attachment, is not your acceptance. You decide what is acceptable and what still needs work. That's a focused local workflow, with human review at the center.
