Prompt compression reduces token count while preserving intent — critical for API cost control and hitting context limits.

Compression Techniques

• Remove filler words ("Please", "Could you", "I would like you to")
• Use abbreviations the AI understands ("w/" instead of "with")
• Replace lengthy descriptions with a role ("As a doctor" vs 3 sentences about medical expertise)
• Remove redundant instructions that the AI infers anyway

Tool

Ask Claude: "Compress this prompt to be 50% shorter while preserving all intent."
