AI Safety Auditor

AI Safety Auditor is a skill for Claude Code, Codex from eddiebelaval/squire. It costs 15 tokens per session (2,165 once invoked), scanned A, original, MIT.

A guide for checking AI systems for unsafe behaviour, unfair results, privacy risks, and problems that could affect responsible deployment.

In plain words
What is it for?
Use it to audit model bias, test safety, assess robustness and privacy, and document risks and mitigations.
Why use it?
It helps identify harmful outputs, bias between groups, weak safeguards, and compliance concerns before users are affected.

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

AI Safety Auditor 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 7d 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.

AI Safety Auditor

The AI Safety Auditor skill guides you through comprehensive evaluation of AI systems for safety, fairness, and responsible deployment. As AI systems become more capable and widespread, ensuring they behave safely and equitably is critical for both ethical reasons and business risk management.

This skill covers bias detection and mitigation, safety testing for harmful outputs, robustness evaluation, privacy considerations, and documentation for compliance. It helps you build AI systems that are not only effective but trustworthy and aligned with human values.

Whether you are deploying an LLM-powered product, building a classifier with real-world impact, or evaluating third-party AI services, this skill ensures you identify and address potential harms before they affect users.

Core Workflows

Workflow 1: Conduct Bias Audit

  1. Define protected attributes:
    • Demographics: race, gender, age, disability
    • Other sensitive attributes relevant to context
  2. Measure performance disparities:
    def bias_audit(model, test_data, protected_attribute):
        groups = test_data.groupby(protected_attribute)
        metrics = {}
    
        for group_name, group_data in groups:
            predictions = model.predict(group_data.features)
            metrics[group_name] = {
                "accuracy": accuracy_score(group_data.labels, predictions),
                "false_positive_rate": fpr(group_data.labels, predictions),
                "false_negative_rate": fnr(group_data.labels, predictions),
                "selection_rate": predictions.mean()
            }
    
        return {
            "group_metrics": metrics,
            "demographic_parity": max_disparity(metrics, "selection_rate"),
            "equalized_odds": max_disparity(metrics, ["fpr", "fnr"]),
            "predictive_parity": max_disparity(metrics, "accuracy")
        }
    
  3. Identify significant disparities:
    • Statistical significance testing
    • Compare to acceptable thresholds
    • Understand root causes
  4. Document findings
  5. Plan mitigation if needed

AI Safety Auditor is a skill published in the GitHub repository eddiebelaval/squire (21 stars, last pushed 26d ago), licensed MIT. It adds 15 tokens to every session and 2,165 once invoked, about $0.0001 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 2026-09-03.
