$claude/security-skill

Security scanning
inside Claude Code.

Install one skill. Tell Claude to scan your app. Get findings, evidence, and AI-assisted fixes -- without leaving your terminal.

$claude plugin marketplace add TeemuSo/launchguard-skill && claude plugin install launchguard@launchguard-skill

Paste into your terminal, then open a new Claude Code session

How it works

01

INSTALL

One command adds the skill to Claude Code. It reads your project files to find deployment URLs and Supabase credentials automatically.

$claude plugin marketplace add TeemuSo/launchguard-skill && claude plugin install launchguard@launchguard-skill
02

SCAN

Tell Claude to scan your app. It runs an external security audit from our servers -- probing every surface an attacker would reach.

$/launchguard scan myapp.com
03

FIX

Claude presents findings with severity, evidence, and impact. Then it offers to fix the issues directly in your codebase -- RLS policies, key rotation, bucket permissions.

What it finds

Exposed Tables

Missing RLS, open read/write, row counts

Leaked Keys

Service role keys in client JavaScript

Open Storage

Publicly listable buckets and files

Exposed RPCs

Server functions callable without auth

Edge Functions

Open to anonymous callers

Hidden Tables

Found via PostgREST error hints

Every finding includes evidence -- actual data from the probe, not guesswork. Write tests use PostgREST's tx=rollback so nothing is persisted.

Also works with
