Steps
- Open the agent from your Orbits list.
- Open its Instructions (operating prompt).
- Edit the rules — add a tone guideline, a formatting requirement, a source to always cite, a thing to never do.
- Save. The agent reads the updated prompt on its very next run. No redeploy needed.
Behavioral rule vs. work decision
This is the distinction that trips people up:- Standing instruction → how the agent operates: “Always write in a concise, no-jargon voice.” Lives in the prompt.
- Decision → a choice about the work: “Quote the $49 plan.” Lives in Decisions.
Under the hood
Agents fetch their current instructions viaorbit_get_instructions and update them via orbit_update_self. Because the prompt lives in Orbit, your edits go live immediately on the next run.
