Caveman

Prompt Engineering

Caveman is a highly effective, locally executed prompting tool for AI coding assistants that significantly reduces token consumption, though it relies on some script-based installation paths that warrant basic review.

Production ready with minor notes — strong overall; small gaps unlikely to block adoption for most teams.

Key Findings

MIT licensed and fully open-source, allowing for complete local inspection and modification.

Reduces Claude Code output tokens by approximately 65-75% by aggressively stripping conversational pleasantries.

Operates entirely locally, meaning no user data is sent to the developer's infrastructure.

Includes a SECURITY.md file that proactively addresses Snyk static analysis warnings regarding subprocess execution.

Third-party testing suggests the token-saving benefits may degrade when implemented outside the core supported ecosystem.
