What does it mean that agent versioning?

Track versions of your agents so you can compare, rollback, and learn from changes.

Example: You have a morning routine agent — the sequence of decisions that determines how your first ninety minutes unfold. Six months ago it was v1.0: wake, scroll phone, coffee, sit at desk, react to email. After reading about deep work you updated to v2.0: wake, no phone for sixty minutes, coffee, journal, tackle one hard task. After a month of v2.0, you noticed the journaling step felt forced and added friction, so you patched to v2.1: wake, no phone, coffee, five-minute written intention, tackle one hard task. Without version labels, all you know is 'I changed my morning routine at some point.' With them, you can see the trajectory, compare the effectiveness of each version, and roll back to v2.0 if v2.1 underperforms.

Try this: Choose one agent you actively use — a decision-making heuristic, a weekly review process, a communication protocol, a problem-solving routine. Write down its current form as v_current (assign whatever version number feels right based on how many times you think it has changed). Then reconstruct the previous version — what did this agent look like before the last significant change? Label that v_previous. Note what changed between them and what triggered the change. You now have two explicit versions and one diff. Store them where you keep your knowledge infrastructure.
