What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

name: ctx-stats
description: |
  Show how much context window context-mode saved this session.
  Displays token consumption, context savings ratio, and per-tool breakdown.
  Read-only — shows stats only, no reset capability.
  To wipe the knowledge base entirely, use ctx_purge instead.

# Context Mode Stats

Show context savings for the current session.

## Instructions

1. Call the `mcp__context-mode__ctx_stats` MCP tool (no parameters needed).
2. **CRITICAL**: You MUST copy-paste the ENTIRE tool output as markdown text directly into your response message. Do NOT summarize, do NOT collapse, do NOT paraphrase. The user must see the full tables without pressing ctrl+o. Copy every line exactly as returned by the tool.
3. After the full output, add ONE sentence highlighting the key savings metric, e.g.:
   - "context-mode saved **12.4x** — 92% of data stayed in sandbox."
   - If no data yet: "No context-mode calls yet this session."

## Purge

- **`ctx_purge(confirm: true)`** — Permanently deletes all indexed content from the knowledge base. Use `/context-mode:ctx-purge` for this.

Questions

What does the Ctx Stats skill do?

Context window optimization for AI coding agents. Sandboxes tool output (98% reduction), persists session memory, and enforces routing across 17 platforms via MCP + hooks.

Is Ctx Stats safe to install?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.

What can Ctx Stats access on my machine?

The audit observed no filesystem, network or shell use at all in its source.

How current is this page?

The grade is for one exact copy of the source (a972bcb29455), read on 2026-10-07. The repository is watched, and a new audit runs when it changes — this is the first audit.
