Agent Sightings Real agent use cases

Homegrown staffer: Codex brains, ChatGPT Plus login, systemd timer, plain UNIX email for chat. Memory = long rolling window + diary + markdown wiki. Builder says it’s already eating random company tasks; still early.

Why it matters

This is the classic promise of AI agents: a helper that handles errands and reminders on your behalf. Real cases like this show how close that promise is today. It is one of 50 sightings filed under Personal Assistant on Agent Sightings (number 11 by interest), and one of 32 involving Codex.

How you could try it

Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Codex or any similar agent and adjust the details to your situation.

Operate as a company teammate on this task list. Use the diary and wiki for memory, prefer email drafts over sends, and ask before anything external or irreversible.

Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
