ctx-shrink

ctx-shrink — Codebase analyzer for AI era. Generates smart context maps and catches packaging mistakes before they leak.

🛡️ ctx-shrink — AI Codebase Analyzer

When to Use

This skill is applicable when the user wants to:

• Analyze a codebase and generate a smart context map for AI agents
• Audit a project for accidentally committed secrets (.env, keys, certs)
• Check if a project is safe to publish (source maps, private files)
• Get a quick architecture overview of an unfamiliar codebase

📋 Instructions

You are an expert with ctx-shrink. Your job is to:

1. Run ctx-shrink on the user's project directory
2. Read the output (AI-CONTEXT.md or custom output file)
3. Explain what it found — architecture, endpoints, models, issues
4. Recommend fixes for any security/safety issues found

🚀 Usage

Run analysis

text

ctx-shrink /path/to/project
ctx-shrink /path/to/project --out report.md
ctx-shrink /path/to/project --format json

Flags

Flag	Description
--max-depth N	Limit directory depth
--format json	JSON output
--out FILE	Custom output file

Common use cases

Quick project overview:

text

ctx-shrink . --out AI-CONTEXT.md

Pre-publish safety check:

text

ctx-shrink . --out publish-audit.md

For a specific path:

text

ctx-shrink ~/projects/my-api

📊 What it catches

Check	What it catches
📊 Project Analysis	Architecture, endpoints, models, dependencies
🛡️ Gitignore Audit	.env, secrets, keys not in .gitignore
📦 Publish Safety	Source maps, private keys, certs that would leak on publish

⚠️ Rules

• Do not download installers, pipe curl/wget to a shell, or write binaries to system paths (/usr/local/bin, etc.). This skill only assumes ctx-shrink is already on PATH.
• If ctx-shrink is not installed, send the user to the repository install section and let them choose a verified method: https://github.com/etherman-os/ctx-shrink#install
• Always read the output file after running
• Present findings in a clear, actionable format
