vendor-third-party-risk

vendor-third-party-risk is a skill for Claude Code, Codex from vaquarkhan/compliance-agent-skills. It costs 114 tokens per session (1,865 once invoked), scanned A, original, MIT.

A procedure for assessing the security and compliance risk of outside vendors, such as cloud hosts, AI providers, and software tools. It covers security questionnaires, SOC 2 reports, inherited controls, risk scores, and ongoing checks.

In plain words
What is it for?
Use it when onboarding or rechecking vendors, reviewing SOC 2 reports, evaluating subprocessors, completing questionnaires, or maintaining a vendor risk register.
Why use it?
It helps organisations decide whether a vendor is acceptable for handling sensitive data and document the reasoning for compliance reviews.

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

vendor-third-party-risk 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.

Vendor Third-Party Risk

Overview

This skill implements third-party risk management (TPRM) for compliance programs—operating with the rigor of GRC platforms (Vanta, Drata, Secureframe) but without assuming a specific vendor tool. It complements hipaa-baa-vendor-assessment (legal BAA focus) with operational security assessment:

  • Inherent/residual risk scoring
  • SOC 2 Type II report review (bridge letters, subservice orgs)
  • Security questionnaire mapping (SIG Lite, CAIQ, custom)
  • Continuous monitoring of vendor status (breach news, certification expiry)
  • Control inheritance decisions for SOC 2 carve-out reports

Applies to LLM providers, cloud hosts, MCP operators, observability SaaS, and identity providers.

When to Use

Use this skill when:

  • Onboarding a new vendor processing customer data, ePHI, or CHD
  • Annual vendor recertification in compliance calendar
  • Reviewing vendor SOC 2 report for subservice organization reliance
  • Completing security questionnaires sent to/from vendors
  • Assessing LLM/AI vendor risk beyond BAA (model security, logging, subprocessors)
  • Building vendor risk register for SOC 2 CC9.2 and HIPAA §164.308(b)
  • Evaluating GRC automation tools themselves as vendors

Do not use this skill when:

  • Drafting BAA legal clause analysis (use hipaa-baa-vendor-assessment)
  • MCP OAuth configuration (use mcp-compliance-integration)
  • Internal employee access reviews (use access-control-identity-audit)

Core Process

Execute steps in order.

Step 1: Vendor tiering

  1. Classify vendors by inherent risk:
Tier Criteria Review depth Examples
T1 Critical ePHI/CHD processing, production access Full assessment + SOC 2 + annual onsite/virtual LLM with BAA, cloud prod, MCP host
T2 High Confidential data, internal network access SOC 2 + questionnaire SIEM, IdP, ticketing
T3 Medium Limited data, no prod access Questionnaire + certification check Marketing SaaS
T4 Low No sensitive data Lightweight attestation Office supplies
