Security Scan

​

When to Activate

• Setting up a new Claude Code project
• After modifying .claude/settings.json, CLAUDE.md, or MCP configs
• Before committing configuration changes
• When onboarding to a new repository with existing Claude Code configs
• Periodic security hygiene checks

​

What It Scans

​

Prerequisites

# 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 .

​

Usage

​

Basic Scan

# 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

​

Output Formats

# 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

​

Auto-Fix

npx ecc-agentshield scan --fix

• Replace hardcoded secrets with environment variable references
• Tighten wildcard permissions to scoped alternatives
• Never modify manual-only suggestions

​

Opus 4.6 Deep Analysis

# Requires ANTHROPIC_API_KEY
export ANTHROPIC_API_KEY=your-key
npx ecc-agentshield scan --opus --stream

1. Attacker (Red Team) — finds attack vectors
2. Defender (Blue Team) — recommends hardening
3. Auditor (Final Verdict) — synthesizes both perspectives

​

Initialize Secure Config

npx ecc-agentshield init

• settings.json with scoped permissions and deny list
• CLAUDE.md with security best practices
• mcp.json placeholder

​

GitHub Action

- uses: affaan-m/agentshield@v1
  with:
    path: '.'
    min-severity: 'medium'
    fail-on-findings: true

​

Severity Levels

​

Interpreting Results

​

Critical Findings (fix immediately)

• Hardcoded API keys or tokens in config files
• Bash(*) in the allow list (unrestricted shell access)
• Command injection in hooks via ${file} interpolation
• Shell-running MCP servers

​

High Findings (fix before production)

• Auto-run instructions in CLAUDE.md (prompt injection vector)
• Missing deny lists in permissions
• Agents with unnecessary Bash access

​

Medium Findings (recommended)

• Silent error suppression in hooks (2>/dev/null, || true)
• Missing PreToolUse security hooks
• npx -y auto-install in MCP server configs

​

Info Findings (awareness)

• Missing descriptions on MCP servers
• Prohibitive instructions correctly flagged as good practice
