Security Scan Skill

Run three independent scanners and summarize results:

• runDependencyAudit()

  for package/dependency vulnerabilities

• runSastScan()

  for static code findings

• runHoundDogScan()

  for privacy/security dataflow findings

Orchestration

For full scans, run scanners in parallel and tolerate per-scanner failures.

const [depResult, sastResult, hounddogResult] = await Promise.allSettled([
  runDependencyAudit(),
  runSastScan(),
  runHoundDogScan(),
]);

const dep = depResult.status === 'fulfilled' ? depResult.value : null;
const sast = sastResult.status === 'fulfilled' ? sastResult.value : null;
const hounddog =
  hounddogResult.status === 'fulfilled' ? hounddogResult.value : null;

Do not fail the whole scan because one scanner errors.

Reporting Findings

After analysis is complete, call

reportVulnerabilities

with the file paths of all vulnerability files in

.local/potential_vulnerabilities/

. Each file must use YAML front-matter with

title

,

level

, and optionally

file_ranges

:

---
title: "Hardcoded database credentials"
level: critical
file_ranges:
  - filepath: "config/database.py"
    range_start: 1
    range_end: 2
---
Description of the vulnerability.

Call the callback via code execution:

await reportVulnerabilities([
  { filePath: ".local/potential_vulnerabilities/hardcoded-secrets-database.md" },
  { filePath: ".local/potential_vulnerabilities/sql-injection-login.md" },
]);

This emits a

ProposedVulnerabilitiesEventData

event for the UI. Call this after writing vulnerability files — writing the files alone is not sufficient to surface findings to the user. If the scan finds no vulnerabilities, skip this callback.

Output Expectations

Return concise results instead of dumping full payloads:

1. Per scanner: status (

   ok

   or

   error

   ) and count by severity.
2. Top critical/high findings with file path and short message.
3. A short remediation plan, with risky/breaking changes clearly called out.
