This repository catalogs the system prompts used by Claude Code, organizing them into browsable categories with token-count estimates for each prompt. It functions as both a prompt library browser and a revision tracker, surfacing the size and complexity of individual prompts to support auditing and prompt engineering decisions.
The project records prompt revisions by parsing git diffs between versions, capturing additions, removals, and token-count changes in a structured changelog. Token counts are approximated from character length using a fixed heuristic ratio, avoiding the need for API calls. Each prompt file includes YAML frontmatter storing category, version, and token estimate, enabling automated browsing and changelog generation. The resulting changelog delta computation provides a clear history of how system prompts evolve over time.
