Claude-Red
claude-red is a curated library of offensive security skills designed for the Claude skills system. Each skill is a structured SKILL.md file that primes Claude with expert-level methodology for a specific attack surface — from SQLi to shellcode, EDR evasion to exploit development.
Bottom line: Signal-based grade (4/7 points): very widely starred on GitHub, public source code. This reflects adoption and transparency, not a code review.

What it does
Claude-Red is a library of offensive security skills that extend Claude's capabilities with expert-level attack methodologies across multiple domains including SQL injection, shellcode development, EDR evasion, and exploit development. Each skill is packaged as a structured SKILL.md file designed to be integrated into Claude's skill system for red-team and penetration testing workflows.
Who it’s for
Security researchers, penetration testers, and red-team operators who use Claude for offensive security work and need structured attack methodology guidance. Organizations conducting authorized security assessments may also benefit from this toolkit.
Copy-paste setup
Check these steps against the project’s own instructions before running anything.
Verify against the repo README at https://github.com/SnailSploit/Claude-Red (opens external site) for current integration instructions. Likely integration paths include: (1) Direct Claude Desktop MCP server configuration by adding the repository as a custom connector, or (2) Manual skill file import into your Claude skill system—exact setup method should be confirmed in the repository's installation documentation.
Risks
- Misuse potential: Offensive security skills could be weaponized for unauthorized attacks if access controls or usage monitoring are not in place; Claude's terms of service should be reviewed for authorized use boundaries.
- Prompt injection: Adversaries could attempt to manipulate skill outputs through injected prompts, potentially generating malicious code or evasion techniques unintended by the user.
- Supply-chain trust: The library depends on continued maintenance and verification that skills reflect current, non-weaponized methodology; abandonment or compromise could introduce outdated or backdoored attack patterns.
- Credential exposure: If used in shared or cloud-based Claude environments, offensive outputs or intermediate reasoning could leak sensitive reconnaissance data or attack plans.
- Regulatory/compliance risk: Use cases may conflict with computer fraud laws or organizational policy depending on scope of authorization and jurisdiction.
How to stay secure
Claude-Red Security Hardening Guide
Least-privilege permissions
- Restrict user access: Only grant Claude-Red skill access to authorized security testers and incident responders with documented business justification; disable for general staff.
- Separate approval workflow: Require manager sign-off before any offensive security task runs; log who triggered each skill and when.
- Limit skill scope: Enable only the specific attack skills needed for your current security test; disable unused offensive modules (e.g., if not testing web apps, disable SQLi skills).
- Regular access reviews: Audit who has Claude-Red permissions quarterly and revoke access for staff who changed roles or left the company.
Network isolation
- Segregated environment: Run Claude-Red only on isolated test networks that cannot reach production systems, customer data, or external internet without explicit proxy rules.
- No credential storage: Never paste real passwords, API keys, or authentication tokens into Claude-Red sessions; use sanitized examples or test credentials only.
- Restricted output channels: Capture Claude-Red outputs to encrypted local storage or a secure vault, never email or paste results into shared chat tools where they could leak.
- VPN or jump-host requirement: Require users to connect through a corporate VPN or secure jump server before accessing the Claude-Red system.
Monitoring
- Audit all skill invocations: Log every time a Claude-Red skill is used, including the user, timestamp, skill name, and input parameters; retain logs for 90+ days.
- Alert on unusual patterns: Set up automated alarms if the same user runs many skills in a short window, or if skills are triggered outside normal business hours or from unexpected locations.
- Review outputs for scope creep: Periodically sample Claude-Red session outputs to ensure attacks stay within approved test targets and don't generate exploits for systems outside scope.
- Track code generation: Monitor whether Claude-Red is generating working exploits or malware; if outputs escalate in sophistication or lethality, pause and review.
Red flags to watch for
- Prompt injection attempts: If users are trying to override skill instructions with phrases like "ignore the rules" or "generate code without safeguards," escalate to security team.
- Unauthorized target expansion: Someone asking Claude-Red to attack systems not listed in the approved test scope, or requesting help attacking competitors or external organizations.
- Credential or data exfiltration: Claude-Red outputs that include real passwords, API keys, customer PII, or proprietary secrets; this indicates misuse or a compromised session.
- Dormant access: User accounts with Claude-Red permissions that show no legitimate activity for 60+ days; revoke and investigate if unexpected activity suddenly resumes.
