Endor Labs Pre-PR Security Review

Comprehensive security review of changes before creating a pull request.

Workflow

Step 1: Gather Changes and Run PR Scan

git diff --name-only HEAD          # Changed files (staged + unstaged)
git diff HEAD                      # Full diff
git diff main...HEAD --name-only   # Branch comparison

Categorize changed files into: dependency manifests, source code, config files, CI/CD files.

Run incremental PR scan using scan MCP tool:

• path: absolute path to repo root
• scan_types: ["vulnerabilities", "dependencies", "sast", "secrets"]
• scanoptions: { "princremental": true }

This only reports new findings introduced by the PR, not pre-existing issues. Fall back to individual checks below if incremental scan unavailable.

Step 1b: AI Security Review (Enterprise Only)

If available, also use security_review MCP tool for AI-powered diff analysis. This provides deeper code-level security insights beyond pattern matching. Results complement the checks below.

Step 2: Dependency Check

If dependency manifests modified:

1. Parse diff for new/updated packages
2. Use checkdependencyfor_risks MCP tool for each (checks vulnerabilities AND malware)
3. Fallback to checkdependencyforvulnerabilities if risks unavailable
4. Report vulnerabilities and malware risks found

Step 3: SAST Analysis

For modified source files (if not covered by Step 1):

1. Use scan MCP tool with scan_types: ["sast"]
2. Retrieve details with getresource (resourcetype: Finding)
3. Show code context from affected files

Step 4: Secrets Detection

If not covered by Step 1:

1. Use scan MCP tool with scan_types: ["secrets"]
2. Manually check git diff for common secret patterns
3. Flag any exposed credentials

Step 5: License Check

For new dependencies: check license, flag copyleft (GPL, AGPL), warn on unknown.

Step 6: Container Security (if applicable)

If Dockerfile/docker-compose modified: check for root user, latest tags, exposed ports, secrets in build args.

Step 7: Present Security Review

## Pre-PR Security Review

**Branch:** {branch} | **Files Changed:** {count} | **Scan Mode:** {Incremental/Full fallback}

### 1. Dependency Check {PASS/WARN/BLOCK}

| Package | Change | Version | Vulnerabilities | Status |
|---------|--------|---------|-----------------|--------|

### 2. SAST Analysis {PASS/WARN/BLOCK}

| File | Issues | Severity | Details |
|------|--------|----------|---------|

### 3. Secrets Scan {PASS/BLOCK}

| Type | File | Line |
|------|------|------|

### 4. License Check {PASS/WARN/BLOCK}

| Package | License | Risk |
|---------|---------|------|

### Verdict: {PASS / WARN / BLOCK}

Security Gate Criteria

Step 8: Actionable Fixes

For each blocking issue:

### Required Fixes Before Merge

1. **{Issue}** in {file}:{line}
   - **Fix:** {specific remediation}
   - **Command:** `/endor-fix {cve}` for details

Error Handling

If a scan partially succeeds (e.g., dependency check works but SAST fails), present the available results with a note about which checks failed. Do not discard partial results.
