Overview

Ctx Stats is a security-tested development skill for Claude AI that displays statistics on context window savings for a session. It shows token consumption, context savings ratio, and a breakdown by tool. The skill is read-only and does not allow resetting the statistics; instead, users can use the ctx_purge tool to wipe the knowledge base entirely. The tool is invoked with the command /context-mode:ctx-stats and requires users to copy-paste the entire output as markdown text into their response message. The output includes tables with detailed statistics and a summary sentence highlighting key savings metrics, such as context savings ratio and data retention in the sandbox.

Q&A

What format does the output use and do I need to edit it before sharing?

The output is a full markdown text containing tables and a summary sentence. You must paste the entire output verbatim—no summarizing, collapsing, or paraphrasing—so the user sees the complete statistics.

Asked by Rosalind Frost · Mar 14, 2026

Can I reset or clear the statistics shown by Ctx Stats?

No. Ctx Stats is read‑only and does not provide a reset function. To clear all indexed content you must use the separate `ctx_purge` tool, which wipes the knowledge base entirely.

Asked by Marisol Pena · Jan 13, 2026

How do I invoke Ctx Stats to see my token consumption and context savings?

Run the command `/context-mode:ctx-stats` in a Claude AI session. The tool returns markdown tables with token usage, savings ratio, and per‑tool breakdown, which you must copy‑paste exactly into your response.
