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

assess-ai-vendor 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 10d 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

/eu-ai-governance:assess-ai-vendor

Use the ai-vendor-assessment skill. Follow the legal source protocol. See connected sources.

Workflow

  1. Identify the exact service, version, contract entities, intended use, deployment, geography, data, model chain, and documents reviewed. For a sparse file, issue a provisional matrix and hold pending evidence recommendation rather than inventing terms or withholding useful triage.
  2. Separate signed terms, incorporated policies, technical evidence, independent assurance, marketing claims, and missing material.
  3. Determine all AI Act roles and check Article 25 role-change triggers. Classify the intended use before applying Article 26 or high-risk provider duties.
  4. When available, use the Lexbeam MCP to validate classification, obligations, deadlines, and decisive provisions.
  5. Review AI Act evidence, GPAI and downstream support, GDPR terms, transfers, security, monitoring, incidents, audit access, change control, exit, liability, and insurance.

Output

Return:

  • recommendation: approve, approve with conditions, hold, or reject
  • scope, facts, assumptions, and document register
  • role and classification analysis
  • evidence matrix with provided, missing, conflicting, or not applicable
  • ranked issues and redlines, each labelled legal duty, contractual control, or recommended practice
  • pre-signing conditions and operating controls
  • unresolved questions and source note

Quote contract language sparingly and include page or section references. Do not rely on static vendor profiles or uncited claims. Do not state that fines are automatically insurable or indemnifiable.

Changes

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.
