auditor-selection

auditor-selection is a skill for Claude Code from bromso/metapowers. It costs 5 tokens per session (754 once invoked), scanned A, original, MIT.

A guide for evaluating and choosing an audit firm for an organization's certification work. It considers the firm's industry and regulatory experience, locations, availability, cost, and schedule.

In plain words
What is it for?
Use it to compare audit firms for certifications such as SOC 2, ISO 27001, or HIPAA-related work. It supports decisions about which firm fits the required expertise, locations, timing, and budget.
Why use it?
It helps replace an informal choice with a comparison based on the organization's actual certification requirements. It also checks that the work is based on an approved compliance scope and audit-readiness status.

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

auditor-selection 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Auditor Selection

Evaluate and select audit firms for "$ARGUMENTS" based on industry expertise, regulation experience, cost, and timeline to find the best fit for the organization's certification goals.

Prerequisites

Read .metapowers/compliance/$ARGUMENTS/00-scope.md. If this file does not exist, tell the user:

Phase 0 (Scope) has not been completed for "$ARGUMENTS". Run /compliance:regulatory-landscape $ARGUMENTS first, or use --skip-checks to bypass.

If --skip-checks is present in $ARGUMENTS, skip this check.

Process

  1. Read context files:

    • Read plugins/compliance/shared/grc-lifecycle-guide.md for GRC methodology reference
    • Read .metapowers/compliance/$ARGUMENTS/00-scope.md for scope and applicable regulations
    • Read .metapowers/compliance/$ARGUMENTS/03-certify.md for audit readiness status
  2. Define selection criteria:

    • Industry expertise — experience with organization's sector
    • Regulation experience — certifications the firm can audit (SOC 2, ISO 27001, HIPAA, etc.)
    • Geographic coverage — can they audit all relevant locations?
    • Team size and availability — can they staff the engagement in the desired window?
    • Cost — engagement fees, travel costs, additional charges
    • Timeline — availability for desired audit window
    • References — client references in similar industry/size
    • Combined audit capability — can they audit multiple standards simultaneously?
  3. Create shortlist:

    • Identify 3-5 candidate audit firms
    • Research firm reputation, specializations, and recent engagements
    • Consider Big 4, mid-tier, and boutique firms based on organization size and needs
    • Check for conflicts of interest
  4. Prepare RFP:

    • Define scope — regulations, locations, systems in scope
    • Define timeline — desired audit window, report delivery date
    • Define deliverables — audit report, management letter, certificate
    • Request pricing structure — fixed fee vs. hourly, payment terms
    • Request team qualifications — lead auditor experience, certifications held
    • Request references — 2-3 comparable clients

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.
