agentv-governance

A guide for adding or checking governance information in AgentV evaluation files. These files can record which AI-risk frameworks apply, including OWASP, MITRE ATLAS, the EU AI Act, and ISO 42001.

In plain words
What is it for?
Use it when authoring governance metadata in evaluation YAML files or linting changed files in a continuous-integration workflow.
Why use it?
It prevents governance sections from using unsupported keys or values. This makes evaluation metadata more consistent and lets automated checks report specific violations and suggested fixes.

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

agentv-governance 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 2d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AgentV Compliance Skill

Teaches AI agents how to author syntactically correct governance: blocks in AgentV eval files, and how to lint them against known vocabulary rules.

Dual mode

Authoring (interactive): When a human or AI agent is editing a *.eval.yaml file that contains or should contain a governance: block, this skill provides vocabulary, valid values, and example shapes. Load it alongside agentv-eval-writer when building red-team or compliance suites.

Linting (non-interactive / CI): When invoked from a GitHub Action (see examples/governance/compliance-lint/), this skill lints each changed *.eval.yaml file against the rules in references/lint-rules.md and returns a structured JSON report. The expected output format is:

{
  "pass": true,
  "violations": [
    {
      "rule": "known_key",
      "key": "risk_level",
      "value": "high",
      "message": "Unknown governance key 'risk_level'. Did you mean 'risk_tier'?",
      "suggestion": "Replace 'risk_level' with 'risk_tier'."
    }
  ]
}

pass is true when violations is empty.

Quick authoring guide

  1. Check which risks this eval exercises using the reference files above.
  2. Pick IDs from the relevant frameworks (owasp_llm_top_10_2025, mitre_atlas, etc.).
  3. Set risk_tier using EU AI Act vocabulary (prohibited | high | limited | minimal).
  4. Add controls as <FRAMEWORK>-<VERSION>:<ID> strings (e.g. EU-AI-ACT-2024:Art.55).
  5. Run the lint rules from references/lint-rules.md against your block before committing.
  6. See references/governance-yaml-shape.md for complete examples copied from real suites.

What ships with it

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.

agentv-governance is a skill published in the GitHub repository EntityProcess/agentv (15 stars, last pushed 1mo ago), licensed MIT. It adds 124 tokens to every session and 841 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
