# Vendor / Third-Party Risk Management Assessment
Assess the vendor and third-party risk management (TPRM) program for "$ARGUMENTS". Evaluate vendor lifecycle management from identification through offboarding, including due diligence, contractual requirements, ongoing monitoring, and subprocessor management.
**Arguments.** `$ARGUMENTS` may contain the project name and optional flags. Take the first token as `<project>` and treat `--skip-checks` as a flag; never include flags in file paths. All paths below use `<project>`. If `--skip-checks` is present, skip the prerequisite check and, **before writing any artifact**, append one line to `.singularskills/log.jsonl`: `{"ts":"<ISO timestamp>","skill":"compliance-vendor-tprm","workflow":"compliance","phase":1,"project":"<project>","event":"skipped","artifact":"01-assess/","note":"<reason or \"none given\">"}`.
## Prerequisites
**Part of a workflow.** This skill is phase 1 (Assess) of the GRC Lifecycle workflow (`compliance`); cross-domain workflows run it too. First check `.singularskills/log.jsonl` for an open run for this project: a `run-started` line with `"project":"<project>"` and no later `run-finished` line for the same `workflow` and `project`. If one exists, the conductor is running you: continue here. Otherwise, if the user asked to start, run, continue or resume a process or workflow rather than this one step, do not continue here: invoke the `workflow` skill with the workflow the user asked for, or `compliance` when they named none, followed by `<project>`; it runs this phase in order, asks before it writes and records the run. Otherwise continue here: a later phase runs on its own, behind its gate.
Run this skill's gate before writing: `sh <this skill's folder>/scripts/gate.sh <project> <project root>`, where `<project root>` is the folder that contains `.singularskills/` (use `.` when you are already there). If it exits non-zero, stop and tell the user what it printed, unless `--skip-checks` was given (see Arguments). On a refusal, before you stop, append this line to `.singularskills/log.jsonl` (create the folder and file if missing): `{"ts":"<ISO timestamp>","skill":"compliance-vendor-tprm","workflow":"compliance","phase":1,"project":"<project>","event":"refused","artifact":"01-assess/","note":"<what the gate printed>"}`. Once the gate has passed, or under `--skip-checks` once you have appended the `skipped` line, append this line before you start work: `{"ts":"<ISO timestamp>","skill":"compliance-vendor-tprm","workflow":"compliance","phase":1,"project":"<project>","event":"started","artifact":"01-assess/","note":""}`.
Read `.singularskills/compliance/<project>/00-scope.md`. If this file does not exist, tell the user:
> Phase 0 (Scope) has not been completed for "<project>". Run `/compliance-regulatory-landscape <project>` first, or use `--skip-checks` to bypass.
## Process
1. **Read context files:**
- Read `references/grc-lifecycle-guide.md` for GRC methodology reference
- Read `references/assessment-template.md` for output structure
- Read `.singularskills/compliance/<project>/00-scope.md` for scope and control framework context
2. **Vendor identification and classification:**
- Assess vendor inventory completeness (all third parties identified and cataloged)
- Evaluate risk-based classification methodology (critical, high, medium, low risk)
- Review classification criteria: data access, system connectivity, business impact, regulatory scope, replaceability
- Assess vendor categorization by type (cloud services, SaaS, professional services, outsourced operations, subcontractors)
- Evaluate concentration risk assessment (dependency on single vendors, geographic concentration)
3. **Due diligence process:**
- Assess pre-engagement due diligence procedures per risk tier
- Evaluate security questionnaire process (SIG, CAIQ, custom questionnaires)
- Review SOC report analysis (SOC 2 Type II, SOC 1, bridging letters, complementary user entity controls)
- Assess penetration testing and vulnerability assessment requirements for vendors
- Evaluate financial stability assessment (credit reports, financial statements, insurance coverage)
- Review legal and regulatory compliance verification (certifications, licenses, regulatory actions)
- Assess business continuity and disaster recovery capability evaluation
- Evaluate privacy impact assessment for vendors processing personal data
4. **Contractual requirements:**
- Assess Data Processing Agreement (DPA) coverage and adequacy
- Evaluate Service Level Agreements (SLAs) with measurable metrics and remedies
- Review security addenda and minimum security requirements
- Assess right-to-audit clauses and audit facilitation provisions
- Evaluate breach notification requirements (timelines, content, cooperation)
- Review data return/destruction clauses upon termination
- Assess liability, indemnification, and insurance requirements
- Evaluate subprocessor approval and notification rights
5. **Ongoing monitoring:**
- Assess periodic reassessment cadence per risk tier (annual for critical, biennial for high, etc.)
- Evaluate continuous monitoring signals (security ratings, breach notifications, news monitoring)
- Review performance monitoring against SLAs and KPIs
- Assess incident and near-miss tracking for vendor-related events
- Evaluate vendor relationship governance (steering committees, business reviews)
- Review compliance certificate and certification renewal tracking
- Assess trigger-based reassessment procedures (material changes, incidents, M&A)
6. **Offboarding procedures:**
- Assess data return and destruction procedures (certificates of destruction, verification)
- Evaluate access revocation process (system access, physical access, credentials)
- Review knowledge transfer requirements for critical vendors
- Assess transition planning and migration support obligations
- Evaluate post-termination confidentiality and data handling obligations
7. **Subprocessor management:**
- Assess subprocessor identification and approval workflow
- Evaluate notification obligations for subprocessor changes (advance notice period)
- Review flow-down requirements (security, privacy, compliance obligations)
- Assess objection rights and procedures for subprocessor changes
- Evaluate fourth-party risk visibility and oversight
8. **Program governance:**
- Assess TPRM policy and procedures documentation
- Evaluate roles and responsibilities (TPRM team, business owners, legal, security, privacy)
- Review TPRM tooling and automation (GRC platform, vendor risk management system)
- Assess reporting and metrics (vendor risk dashboards, board reporting)
- Evaluate exception and risk acceptance processes
9. **Write the artifact** to `.singularskills/compliance/<project>/01-assess/vendor-tprm.md` following the assessment template structure with:
- **Vendor Inventory** — completeness and risk classification coverage
- **Due Diligence** — process maturity per risk tier and assessment coverage
- **Contractual Framework** — DPA, SLA, security, and audit clause coverage
- **Ongoing Monitoring** — reassessment cadence, continuous monitoring, and performance tracking
- **Offboarding** — data destruction, access revocation, and transition procedures
- **Subprocessor Management** — identification, approval, and flow-down requirements
- **Program Governance** — policy, roles, tooling, and reporting
- **Evidence Inventory** — existing evidence and evidence gaps
- **Remediation Priorities** — ranked list of gaps to address
## Output
The vendor TPRM assessment written to `.singularskills/compliance/<project>/01-assess/vendor-tprm.md`. Present a summary to the user highlighting:
- Vendor inventory completeness and risk classification coverage
- Due diligence and contractual coverage rates by risk tier
- Ongoing monitoring maturity and reassessment compliance
- Top 3 gaps requiring remediation
**Record the run.** After you have written the artifact, append this line to `.singularskills/log.jsonl` (the `started` line of Prerequisites, with `"event":"finished"`): `{"ts":"<ISO timestamp>","skill":"compliance-vendor-tprm","workflow":"compliance","phase":1,"project":"<project>","event":"finished","artifact":"01-assess/","note":""}`.
Open the artifact with this frontmatter (`agent` is the agent you run in, or `unknown`; `gate` is `passed` when the gate ran clean and `skipped` under `--skip-checks`):
```yaml
---
skill: compliance-vendor-tprm
workflow: compliance
phase: 1
project: <project>
started: <ISO timestamp>
finished: <ISO timestamp>
agent: <the agent you run in, or "unknown">
gate: <passed|skipped>
---
```
End the artifact with `## Decisions` and `## Open questions`, in this shape:
```markdown
## Decisions
- <what was chosen> — <why> — <what was rejected>
## Open questions
- <what the next phase or a reviewer must settle>
```
End the artifact with this paragraph, verbatim:
> **Not legal or audit advice.** This artifact supports preparation for compliance work; certification, attestation and regulatory conclusions require a qualified auditor or counsel.
