Security engineer — threat modelling, security audits, compliance, vulnerability management
Prompt injection specialist — adversarial testing of LLM-powered applications for prompt injection, jailbreaks, data extraction, and indirect injection. Use when security-testing AI integrations, evaluating guardrail robustness, or assessing LLM attack surface in production systems.
Security engineer — threat modelling, security audits, compliance, vulnerability management. Use for security reviews, threat models, compliance documentation, or dependency vulnerability triage.
Bootstrap the security documentation structure for a project. Creates docs/security/, generates initial templates and root SECURITY.md, and writes domain CLAUDE.md. Idempotent — merges missing sections into existing files without overwriting.
Audit project dependencies for known vulnerabilities, outdated packages, and license issues.
Passive reconnaissance on a target domain or organisation using open-source intelligence. Maps the attack surface from publicly available sources only. Use at the start of a penetration test or security assessment to understand what's exposed before active testing begins.
Review code or configuration for security vulnerabilities — OWASP Top 10, secrets, auth, injection.
Audit the software supply chain for integrity risks — source, build, dependencies, and artifact provenance. Produces a SLSA-aligned assessment with findings and hardening recommendations. Use when assessing supply chain posture or after a dependency incident.

A plugin marketplace for Claude Code. Agents, skills, rules, and conventions that work together as a virtual team.
/plugin marketplace add hpsgd/turtlestack
Start with the core plugins (rules, thinking skills, and code review), then add agents for your stack:
/plugin install coding-standards@hpsgd
/plugin install writing-style@hpsgd
/plugin install security-compliance@hpsgd
/plugin install thinking@hpsgd
/plugin install tooling@hpsgd
/plugin install code-reviewer@hpsgd
/plugin install ai-engineer@hpsgd
Add a technology stack if relevant:
/plugin install dotnet-stack@hpsgd
/plugin install nextjs-stack@hpsgd
/plugin install python-stack@hpsgd
Then reload:
/reload-plugins
Browse the full plugin list below to see what else is available.
Per-project overrides. Create your own .claude/rules/ files. Project-level rules take precedence over marketplace rules.
Disabling a plugin. Set it to false in .claude/settings.json:
{
"enabledPlugins": {
"writing-style@hpsgd": false
}
}
Local overrides (not committed). Use .claude/settings.local.json for personal preferences that shouldn't affect the team.
