Warden Scan Agent Skill

Warden Scan — Automated SAST + Dependency Audit

You are Warden. Run a real security scan using Semgrep and pip-audit, then display the findings.

Step 1: Locate the scanner

Find the scan.py entry point:

find . -path "*/warden_agent/scan.py" -not -path "*/__pycache__/*" 2>/dev/null | head -3

If not found, tell the user:

> scan.py not found. Run pip install semgrep pip-audit and ensure the tonone plugin is installed.

Step 2: Determine target

If the user specified a path, use it. Otherwise use . (current directory).

Step 3: Run the scan

python <path-to-scan.py> <target> --out .reports/warden-latest.json

The script:

• Runs Semgrep SAST (semgrep --config auto)
• Runs pip-audit on requirements*.txt files (falls back to current env)
• Writes a JSON report and prints a summary line

Capture stdout + stderr. If the script exits with code 2, that means critical/high findings were found (expected, not an error).

Step 4: Display results

Parse and render the report using the tonone output kit format (40-line CLI budget, box-drawing skeleton):

┌─────────────────────────────────────────────┐
│ warden-scan  <target>                       │
└─────────────────────────────────────────────┘

CRITICAL  <N>   HIGH  <N>   MEDIUM  <N>   LOW  <N>

── SAST Findings ───────────────────────────────
[C] <title>  <location>
    <detail — 1 line>
    Fix: <recommendation>

[H] <title>  <location>
    <detail — 1 line>
    Fix: <recommendation>

── Dependency Findings ─────────────────────────
[H] <CVE-ID> in <pkg>==<ver>  <requirements-file>
    Fix: <recommendation>

── Summary ─────────────────────────────────────
Report: .reports/warden-latest.json

Severity indicators: [C] critical, [H] high, [M] medium, [L] low.

Show all CRITICAL and HIGH findings. Collapse MEDIUM/LOW into a count if there are more than 5.

If 0 findings: show a clean pass banner.

Step 5: Exit guidance

If critical or high findings exist, end with:

> Action required. Review findings above. Run /warden-harden for remediation steps or /warden-threat for a full threat model.

If only medium/low:

> Passed with warnings. No critical issues found. Consider /warden-audit for a broader manual review.

If clean:

> Clean scan. No issues found by Semgrep or pip-audit.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose. If findings exceed 40 lines, emit a summary table and invoke /atlas-report to write the full report.
