DryRunSecurity Skills for AI Coding Assistants

Official skills for AI coding assistants (Claude Code, Cursor, Windsurf, Codex) to help fix security vulnerabilities identified by DryRunSecurity.

What This Does

When DryRunSecurity scans your pull request and leaves a comment about a security vulnerability, this skill helps your AI coding assistant understand and fix the issue. Instead of just telling you there's a problem, you get guided remediation.

The Flow:

DryRunSecurity finds vulnerability → Comments on your PR →
You ask your AI assistant to fix it → Skill guides contextual fix →
You push the fix → DryRunSecurity approves

Philosophy

Context is King. DryRunSecurity spends significant effort understanding your codebase to identify real vulnerabilities. This remediation skill does the same - it guides AI assistants to:

1. Understand your codebase - Existing patterns, tech stack, utilities
2. Research authoritative sources - Official docs, OWASP, CWE references
3. Apply contextual fixes - Matches your code style, uses your existing utilities
4. Explain and verify - Why it was vulnerable, why the fix works

No static cheat sheets. No generic examples. Fixes grounded in your code.

Installation

For Cursor

Download to your project (always latest):

curl -o .cursorrules https://raw.githubusercontent.com/DryRunSecurity/external-plugin-marketplace/main/standalone/.cursorrules

Or pin to a specific version:

curl -o .cursorrules https://raw.githubusercontent.com/DryRunSecurity/external-plugin-marketplace/v1.0.0/standalone/.cursorrules

For Windsurf

Download to your project (always latest):

curl -o .windsurfrules https://raw.githubusercontent.com/DryRunSecurity/external-plugin-marketplace/main/standalone/.windsurfrules

Or pin to a specific version:

curl -o .windsurfrules https://raw.githubusercontent.com/DryRunSecurity/external-plugin-marketplace/v1.0.0/standalone/.windsurfrules

For Claude Code

# Add the marketplace
/plugin marketplace add DryRunSecurity/external-plugin-marketplace

# Install the remediation plugin
/plugin install dryrun-remediation@dryrunsecurity

For Other AI Assistants (VS Code, Codex, etc.)

Download or copy standalone/RULES.md into your AI assistant's system prompt or rules configuration.

Versioning

All skill files include a version number in their header:

# Version: 1.0.0

Version Policy

• main branch - Always contains the latest version
• Git tags (v1.0.0, v1.1.0, etc.) - Pinned releases

Staying Up to Date

Option 1: Always latest (recommended for most users)

# Re-run the curl command to get the latest
curl -o .cursorrules https://raw.githubusercontent.com/DryRunSecurity/external-plugin-marketplace/main/standalone/.cursorrules

Option 2: Pin to a version

# Use a specific tag
curl -o .cursorrules https://raw.githubusercontent.com/DryRunSecurity/external-plugin-marketplace/v1.0.0/standalone/.cursorrules

Checking Your Version

Look at the top of your rules file:

# DryRunSecurity Vulnerability Remediation
# Version: 1.0.0

Compare with the latest release.

Usage

Once installed, share the DryRunSecurity finding with your AI assistant:

"DryRunSecurity found a SQL injection vulnerability in my PR.
Here's the comment: [paste comment]. Can you help me fix it?"

Or point directly to the file:

"Fix the SQL injection in src/handlers/user.go line 45"

The skill guides the assistant to:

1. Read and understand your affected code
2. Find how similar issues are handled elsewhere in your codebase
3. Research the authoritative fix for your framework/version
4. Apply a fix that matches your existing patterns
5. Explain why it was vulnerable and why the fix works

Supported Vulnerability Types

The skill works for any vulnerability DryRunSecurity identifies, including:

• SQL Injection, XSS, CSRF, SSRF
• IDOR, Mass Assignment, Auth Bypass
• Hardcoded Secrets, Path Traversal
• Command Injection, Prompt Injection
• Race Conditions, Deserialization issues
• Cryptographic weaknesses
• And any other security finding
