SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill solves the problem of token bloat in LLM-directed documents. It reduces the size of system prompts, instructions, and skill definitions by replacing redundant explanations with precise pointers, ensuring the model remains efficient without losing critical project-specific context.

Core Features & Use Cases

  • Distill Mode: Performs an A/B-validated loop to produce the smallest possible document that maintains identical behavioral output.
  • Local Mode: Executes a rapid core-to-pointer pass for short snippets, replacing standard definitions with concise cues.
  • Use Case: If you have a massive, verbose CLAUDE.md file that is consuming too many tokens, use this skill to distill it into a minimal, behaviorally equivalent version that still enforces all your project rules.

Quick Start

Use the semantic-compress skill to distill the attached CLAUDE.md file into the smallest version that maintains the same behavior.

FAQPage Schema
How do I shrink LLM prompts while preserving behavior?

To shrink LLM prompts while preserving behavior, replace standard conceptual explanations with minimal pointers and validate the compressed output against a defined transfer set of test cases to ensure identical model behavior.

What is the best way to reduce token bloat in a verbose CLAUDE.md file?

The best way to reduce token bloat in a verbose CLAUDE.md file is to use A/B-validated distillation loops that produce the smallest possible document while maintaining identical behavioral output and enforcing all project rules.

How does A/B-validated distillation work for prompt engineering?

A/B-validated distillation works by iteratively compressing LLM-directed documents and testing the reduced output against a transfer set of test cases to verify it induces the exact same model behavior as the original.

Do I need test cases to compress system prompts without losing project-specific context?

Yes, you need a defined transfer set of test cases to verify that the compressed system prompt induces the same model behavior as the original document and preserves all bespoke project constraints.

Can I do a rapid core-to-pointer pass for short instruction snippets?

Yes, you can execute a rapid local mode core-to-pointer pass for short snippets that replaces standard conceptual definitions with concise cues, ensuring your instruction set remains efficient.

What are the limitations of semantic compression for LLM instruction sets?

The main limitation is the requirement for a defined transfer set of test cases; without these test cases to verify behavioral equivalence, the compression cannot guarantee the model will adhere to bespoke project constraints.
