What it is
This repository contains an up-to-date list of Claude Code system prompts and their associated token counts, including prompts for sub-agents (Explore, Plan), creation assistants (CLAUDE.md creation, Status line setup), slash commands, and various utilities. It also includes a CHANGELOG and release notes tied to Claude Code v2.1.x.
How it works
Prompts are organized as separate Markdown files under system-prompts for different agents and utilities. Each entry lists the prompt name and an associated token count (tks). The README describes extraction: prompts are extracted from Claude Code's compiled source to reflect exact in-installation usage. It also references a tweak utility for customization. The latest releases show commit references and token changes per version.
Getting started
- The README includes instructions to use tweakcc for modifying specific prompt pieces: "Use tweakcc. It—\n- lets you customize the individual pieces of the system prompt as markdown files, and then\n- patches your npm-based or native (binary) Claude Code installation with them, and also\n- provides diffing and conflict management for when both you and Anthropic have conflicting modifications to the same prompt file."
