gee

A salience engine for persistent agent working memory.

EEG reversed — an EEG reads brain activity, gee generates it. Also just a
thing you say when something occurs to you.

What It Does

gee maintains a set of awareness items, each with an activation score that
changes continuously based on time, context, and randomness. Items that cross
a threshold get surfaced — either injected into an agent's context or pushed
as an interrupt.

This is not a task list, not a notification system, not RAG. It's a continuous
activation model inspired by cognitive architectures (ACT-R, Park et al.'s
Generative Agents) with two key additions: mode-gated retrieval (task-focused
vs. default mode network) and stochastic noise for serendipitous recall.

The Equation

activation = temporal_curve(t, item)
           + α(mode) * immediate_resonance(item, context, mode)
           + β(mode) * recent_resonance(item, history, mode)
           + noise(σ(mode))

Temporal curve — intrinsic urgency over time. A ramp before a meeting,
a slow rise for an overdue task, a trapezoid for a daily habit window.

Immediate resonance — "am I thinking about this right now?" Embedding
similarity between the item and current context (conversation, events).

Recent resonance — "have I been thinking about this lately?" Engagement
history across recent sessions (task mode) or independent idle cycles (DMN mode).

Noise — gaussian perturbation. Tight in task mode, wide in DMN mode.
This is what makes forgotten items occasionally surface. The stochastic recall
that humans experience as "I wonder how so-and-so is doing."

Modes

Task mode — active during sessions. Focused retrieval. High threshold,
low noise. Surfaces what's relevant to the current work.

DMN mode — active during idle. Diffuse retrieval. Low threshold, high
noise. Mind-wandering. Items that independently surface across multiple idle
cycles accumulate a "recurring thought" signal.

Surfacing

• > 0.8 — interrupt. Push a message unprompted.
• 0.5–0.8 — inject into next session as context. Available, not forced.
• < 0.5 — stored, retrievable on demand, not in active awareness.
