Agent Design

Trigger Design

Create reliable conditions that activate specific behaviors.

Triggers are the entry points of behavior

Without a clear trigger an agent never activates no matter how well designed.

Internal triggers versus external triggers

Internal triggers are thoughts and feelings — external triggers are events and cues.

Reliable triggers are specific and observable

A trigger must be something you can detect consistently.

Environmental triggers are the most reliable

Physical cues in your environment trigger more reliably than mental intentions.

Time-based triggers

Using specific times or time intervals as triggers leverages your existing time awareness.

Event-based triggers

Linking an agent to a specific event like arriving at work or opening your laptop.

Emotional triggers

Using specific emotional states as activation signals for pre-designed responses.

Chained triggers

The completion of one agent becomes the trigger for the next.

Trigger sensitivity calibration

Too sensitive and the agent fires too often — too insensitive and it never fires.

False positive triggers

When a trigger fires in the wrong context you need to add qualifying conditions.

Missed triggers

When you fail to notice a trigger you need to make it more salient.

Trigger stacking

Combining multiple trigger conditions for higher-specificity activation.

Trigger placement in your environment

Position trigger cues where you will encounter them at the right moment.

Digital triggers

Alarms, notifications, and calendar events as systematic trigger mechanisms.

Social triggers

Other people can serve as triggers — asking someone to remind you is a social trigger.

Trigger fatigue

Too many triggers overwhelm your attention — curate ruthlessly.

The trigger audit

Regularly review your triggers to ensure they are still relevant and well-calibrated.

Trigger design is UX design for your own mind

You are designing the user experience of your own cognitive systems.

Progressive trigger refinement

Start with broad triggers and narrow them as you learn what works.

Mastery is having the right trigger for every important situation

A complete set of well-tuned triggers means you respond appropriately to everything that matters.
