Scan your Claude Code configuration (.claude/ directory) for security vulnerabilities, misconfigurations, and injection risks using AgentShield. Checks CLAUDE.md, settings.json, MCP servers, hooks, and agent definitions.
From clarcnpx claudepluginhub marvinrichter/clarc --plugin clarcThis skill uses the workspace's default tool permissions.
Designs and optimizes AI agent action spaces, tool definitions, observation formats, error recovery, and context for higher task completion rates.
Enables AI agents to execute x402 payments with per-task budgets, spending controls, and non-custodial wallets via MCP tools. Use when agents pay for APIs, services, or other agents.
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.
Audit your Claude Code configuration for security issues using AgentShield or manual review patterns.

security-review: This skill audits your Claude Code configuration (.claude/directory, hooks, MCP configs, CLAUDE.md) for injection risks and misconfigurations. Usesecurity-reviewwhen you need to audit application code — authentication, input validation, OWASP Top 10.
.claude/settings.json, CLAUDE.md, or MCP configs| File | Checks |
|---|---|
CLAUDE.md | Hardcoded secrets, auto-run instructions, prompt injection patterns |
settings.json | Overly permissive allow lists, missing deny lists, dangerous bypass flags |
mcp.json | Risky MCP servers, hardcoded env secrets, npx supply chain risks |
hooks/ | Command injection via interpolation, data exfiltration, silent error suppression |
agents/*.md | Unrestricted tool access, prompt injection surface, missing model specs |
AgentShield must be installed. Check and install if needed:
# Check if installed
npx ecc-agentshield --version
# Install globally (recommended)
npm install -g ecc-agentshield
# Or run directly via npx (no install needed)
npx ecc-agentshield scan .
Run against the current project's .claude/ directory:
# Scan current project
npx ecc-agentshield scan
# Scan a specific path
npx ecc-agentshield scan --path /path/to/.claude
# Scan with minimum severity filter
npx ecc-agentshield scan --min-severity medium
# Terminal output (default) — colored report with grade
npx ecc-agentshield scan
# JSON — for CI/CD integration
npx ecc-agentshield scan --format json
# Markdown — for documentation
npx ecc-agentshield scan --format markdown
# HTML — self-contained dark-theme report
npx ecc-agentshield scan --format html > security-report.html
Apply safe fixes automatically (only fixes marked as auto-fixable):
npx ecc-agentshield scan --fix
This will:
Run the adversarial three-agent pipeline for deeper analysis:
# Requires ANTHROPIC_API_KEY
export ANTHROPIC_API_KEY=your-key
npx ecc-agentshield scan --opus --stream
This runs:
Scaffold a new secure .claude/ configuration from scratch:
