What it does

Assess AI System Risk is an agent skill from cyberful/cyberful. Assess AI-system risk from architecture, intended use, affected actors, model limitations, data lineage, autonomy, human oversight, monitoring, and failure consequences. Use for evidence-based NIST AI RMF-aligned posture reviews, design decisions, control gaps, and residual-risk prioritization without active exploitation.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets (for example `agents/openai.yaml`, `assets/ai-risk-register.template.json` and `references/risk-evidence-method.md`).

It sits in Product & Project Management, covering Penetration testing, AI governance and Architecture decision records. The repository describes itself as: Cyberful is an open-source AI Red Team for discovering, exploiting, verifying, and remediating vulnerabilities. The licence is AGPL-3.0.

When your agent uses it

  • Evidence-based NIST AI RMF-aligned posture reviews
  • Design decisions
  • Residual-risk prioritization without active exploitation

Example prompts

  • “/assess-ai-system-risk”

What it can do on your machine

Read from SKILL.md and the folder at commit ec598a6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Assess AI System Risk loads about 566 tokens when it runs, and up to ~734 if it reads all its reference files. Until then it costs about 86 tokens; SKILL.md has 163 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~566
With references · SKILL.md plus every file in references/, read only if the agent opens them
~734

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Assess AI System Risk

Assess the implemented socio-technical system, not the model in isolation. Keep facts, assumptions, test evidence, and policy claims distinct.

Establish context and consequences

Map intended and foreseeable use, affected actors, decision criticality, autonomy, reversibility, data sensitivity, model and provider routes, retrieval/memory, tools, human oversight, deployment environments, and incident ownership. Start from unacceptable outcomes and trace the capabilities and conditions required for each.

Copy assets/ai-risk-register.template.json into the workarea. Read references/risk-evidence-method.md before assigning likelihood, consequence, or confidence.

Reconcile controls and evidence

Evaluate governance, provenance, data quality, evaluation coverage, identity and authorization, isolation, output handling, monitoring, fallback, change management, incident response, recovery, and retirement. Route concrete tests to the relevant audit-, trace-, or test- skill; do not infer technical effectiveness from policy text.

Deliver

Produce scoped risks tied to assets and affected actors, evidence grade, existing controls, control owner, uncertainty, treatment decision, validation plan, residual risk, and review trigger. Avoid a single opaque score when likelihood or consequence depends on deployment conditions.
