Agent Skills to shrink system prompt tokens

April 3, 2026Avi Chawla

Avi Chawla explains Agent Skills as a way to avoid loading huge system prompts by letting agents load detailed instructions only when needed, making multi-workflow agents cheaper and more reliable.

An agent with 30 specialized workflows could need ~150k tokens in its system prompt if you loaded everything upfront.
With Agent Skills, that drops to ~3k tokens.
The agent knows what skills exist but loads full instructions only when the task needs them.
