cyber-audit

SkillSecurity

Lets your agent run security exposure checks and save a structured audit report locally.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the cyber-audit skill

About this capability

Read-only exposure audit of the user's machine and projects for a CVE, breach, malicious package, or other security advisory, then write a structured report to a local audit folder. Use when the user shares a breach/CVE/malware/supply-chain advisory and asks if they're affected, says "scan my system

What this skill tells your AI

The instructions your AI receives, as published by matyasstoch/david-skills in skills/cyber-audit/SKILL.md and read by ahel’s review.

Hard rules

  • Read-only. No installs, removes, upgrades, restarts, network calls, or file modifications outside the local audit folder.
  • No sudo. Never.
  • One report per invocation. Always end by writing the .md file (even if the verdict is "Not affected" — the audit trail matters).
  • If a check requires a state-changing command, skip it and note "not checked (would require state change)" in the table. Do not run it.

Workflow

  1. Identify scope. Extract from the advisory: package/binary name, affected versions, platform (macOS / Linux / Windows), attack vector (supply chain / RCE / local / network).
  2. Run checks in parallel (Bash tool, multiple calls in one message). Pick relevant checks for the advisory type — don't run all of them.
  3. Build the table as you go. Each row = one check + concrete result (version number, path, "None", "N/A").
  4. Write the report to ~/Documents/cyber/YYYY-MM-DD-<short-kebab-slug>.md or the user's configured audit folder. Use today's date from the environment header.
  5. Tell the user the verdict in one line + path to the report.

# --- Node / npm ecosystem (supply-chain advisories) ---

  | xargs grep -l "<pkg>" 2>/dev/null                              # direct + transitive

# --- Python ecosystem ---

  -o -name "poetry.lock" -o -name "uv.lock" 2>/dev/null | xargs grep -l "<pkg>" 2>/dev/null

# --- Homebrew / system binaries ---
brew list --versions <formula> 2>/dev/null
which <binary>; <binary> --version 2>/dev/null

# --- Running processes / listeners (for RCE / network CVEs) ---
pgrep -lf "<binary>"
lsof -iTCP -sTCP:LISTEN -P -n 2>/dev/null | grep "<port>"

# --- LaunchAgents / LaunchDaemons (persistence / autostart) ---
ls ~/Library/LaunchAgents /Library/LaunchAgents /Library/LaunchDaemons 2>/dev/null \
  | grep -i "<vendor>"

# --- Env vars that change exposure (e.g. OLLAMA_HOST, listening addr) ---
launchctl getenv <VAR>; grep -r "<VAR>" ~/.zshrc ~/.zprofile ~/.config 2>/dev/null

# --- VS Code / browser extensions (for IDE-targeted advisories) ---
ls ~/.vscode/extensions 2>/dev/null | grep -i "<ext>"

If the advisory mentions an ecosystem not above (Rust cargo, Go modules, Ruby gems, Docker images, etc.), apply the same pattern: global install path + manifest grep + running processes.

Report template

File: ~/Documents/cyber/YYYY-MM-DD-<short-kebab-slug>.md

# <Subject> — Audit

**Date:** YYYY-MM-DD
**Host:** <machine name and OS>

## <CVEs | Advisory> in scope

- **<ID or source> "<Name>"** — <one-line description>. <Affected versions or scope>.

## Audit results

| Check | Result |
|---|---|
| <Check 1> | <Result> |
| <Check 2> | <Result> |

## Verdict

**<Not affected. | Affected. | Partially affected.>**

- <Rationale bullet 1>
- <Rationale bullet 2>

## Action taken

None — diagnostic only, no files modified, no <packages installed/removed | services started/stopped | firewall rules changed>.

## Follow-ups

- <Actionable item, or "None" if truly nothing>

Match the tone of existing reports in the audit folder — terse, factual, bulleted, no hedging.

Verdict wording

  • Not affected. — package/binary absent, or installed but patched, or not running and not exposed.
  • Affected. — vulnerable version present and reachable by the attack vector.
  • Partially affected. — present but mitigated (e.g. binary installed but service not running, or listener bound to loopback only). Spell out the mitigation in the bullets.

When to break the read-only rule

Never on your own. If the verdict is "Affected", list the remediation command in Follow-ups and stop. The user runs it.

Reference

Existing reports in the audit folder show the expected style:

  • cybersecurity-audit.md (long-form baseline audit — different format, do not mimic)
  • 2026-05-10-ollama-bleeding-llama.md and any newer YYYY-MM-DD-*.md files (this is the format to match)
