start-audit

start-audit is a skill for Claude Code from allsmog/vuln-scout. It costs 23 tokens per session (352 once invoked), scanned A, original, MIT.

A guided workflow for carrying out a first security audit of a codebase, including setup checks, scope definition, threat analysis, scanning, verification, and reporting. It stores an audit plan, findings, review data, and an evidence bundle in the project.

In plain words
What is it for?
Use it to audit a repository or monorepo—a project containing multiple related packages or services—by mapping the application, identifying threats, scanning for vulnerabilities, reviewing findings, verifying selected issues, and producing a report.
Why use it?
It gives a new audit a defined order and records the results so the review can be followed and repeated.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

start-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Start Audit

Use this task skill when the user asks to start a security audit, audit this repo, perform a security review of a codebase, or review this codebase for vulnerabilities.

Workflow

  1. Run python3 vuln-scout/scripts/doctor.py --strict or ask the user to address missing quick-profile dependencies.
  2. Trigger session-init and large-codebase-check hooks when the target is a repo or monorepo.
  3. Run /vuln-scout:scope to establish boundaries and write .claude/audit-plan.md.
  4. Call app-mapper, then /vuln-scout:threats, then threat-modeler.
  5. Run /vuln-scout:scan --profile quick first; use deep only when optional analyzers are installed or requested.
  6. Call code-reviewer on prioritized findings.
  7. Run /vuln-scout:verify per finding that needs confirmation.
  8. Finish with /vuln-scout:report --format bundle --output evidence-bundle.

When NOT To Trigger

Do not trigger for knowledge-only questions about STRIDE, OWASP, dangerous functions, framework patterns, compliance mapping, exploit techniques, or vulnerability classes. Let those knowledge skills answer directly unless the user asks to audit a target.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
