SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Compresses internal vault prose to reduce token usage while preserving meaning.

Core Features & Use Cases

Caveman-style compression removes articles, filler words, hedging, and other verbose prose while preserving critical data such as file paths, dates, and code blocks.
Scope control targets internal system files only and explicitly excludes work documents and SKILL.md.
Reporting provides per-file compression metrics and an aggregate savings summary to validate efficiency.
Use Case: shrink long memory and vault notes before archival or transfer to reduce context size.

Quick Start

Run /cerebro-caveman on target files to compress internal vault prose while preserving critical data.

FAQPage Schema

How do I reduce token usage in memory and vault notes?▼

Compress internal vault prose by removing articles, filler words, and hedging to reduce token usage while preserving meaning. This method targets system files like Claude System and memory files, achieving 50-75% size reduction safely.

What is caveman-style compression for markdown memory files?▼

Caveman-style compression removes articles, filler words, and hedging from prose while preserving critical data such as file paths, dates, and code blocks. It targets internal system files only, explicitly excluding work documents and SKILL.md.

Does vault prose compression preserve code blocks and frontmatter?▼

Yes, the compression process explicitly preserves code blocks, frontmatter, and file paths. It also ensures SKILL.md is never modified, and it reports per-file and aggregate savings metrics to validate efficiency.

How do I run a full-pass compression on internal system files?▼

Run the compression command on target files to compress internal vault prose. The tool supports targeted, full-pass, and new-content modes, and reports per-file and aggregate savings to validate efficiency.

Can I compress work documents and SKILL.md files safely?▼

No, the compression scope explicitly excludes work documents and SKILL.md. It operates on internal system files only, such as Claude System and memory files, to ensure critical configuration and work data remain untouched.

What are the limitations of caveman-style text compression?▼

The main limitation is that it operates on internal system files only, excluding work documents and SKILL.md. Additionally, caveman-style rules may reduce prose readability for humans, though meaning and critical data are preserved.
