The category name for reusable AI agent actions.
Agent Subroutines are deterministic workflows that AI agents can call instead of rediscovering every click, form, API request, and browser path from scratch.

Agents are too expensive on repeat work
Every repeated browser workflow should not run through a full LLM loop every time.
The pattern is emerging
Explore once, capture the workflow, replay deterministically, use AI only for ambiguity and repair.
The layer needs a name
Agent Subroutines is a clean category term for reusable, callable agent behavior.
Why now
Browser agents are moving from demos to production. The bottleneck is no longer “can an agent click?” — it is cost, determinism, replay, and operational reliability.
Core workflow
- Agent explores a task once
- The successful path is captured
- Future runs execute as deterministic subroutines
- LLMs handle parameter selection, ambiguity, and self-healing
