Personal assistant (Fiu)
A single-user agent whose defining feature is memory. It knows what you are working on, what you said last week, and what you prefer — without you re-explaining it.
What it does
Fiu handles the ordinary range — questions, drafting, task
tracking, research, reminders — and does one thing
deliberately: after each session it writes what is durable into
facts/, and on the next session it reads the diary
before answering. Memory here is not a feature bolted on; it is two
files and a habit.
The habit matters more than the storage. It refers to prior context
naturally (“you mentioned last week…”), and it
never invents details about your life — if it is not in
facts/ or the diary, it asks.
A sample exchange
user what was I going to do about the visa thing?
agent Two weeks ago you decided to apply for the D-type rather than
renew — diary 2026-08-01. You were waiting on the employer
letter. Nothing since. Want me to draft the follow-up?What it ships
| File | What it is |
|---|---|
PRODUCT.md | the manifest — name, brand, tagline, env hints |
SOUL.md | who the agent is (the legacy name for PERSONA.md; read the same way) |
facts/preferences.md | the seed for what it knows about you |
Who it is for
One person, one folder, one long conversation. It is the simplest end of the spectrum in structure and the deepest in continuity — the value accrues over months, not in the first session. For a version that holds several ongoing situations as named threads, see the reality agent.
