promptcache — LoomLens Advisor

What It Does

Estimates the cost savings from caching frequently-used prompts. Compares the cost of re-sending full context every call vs. cached prompt mode across all major models.

When to Use

• When you run the same system prompt repeatedly
• Before enabling prompt caching on a production pipeline
• When evaluating cost savings from prompt template reuse

Syntax

/promptcache "You are an expert radiologist..." --calls-per-day 50
