benchmark-audit

benchmark-audit is a skill for Claude Code, Codex from yogsoth-ai/de-anthropocentric-research-engine. It costs 29 tokens per session (902 once invoked), scanned A, original, Apache-2.0.

A research skill for systematically assessing AI and machine-learning benchmarks. It checks documentation, whether the benchmark measures what it claims to measure, statistical strength, maintenance, and known ways the results can fail.

In plain words
What is it for?
Use it to audit benchmarks, review their documentation, check for data contamination, break down their metrics, and create quality reports.
Why use it?
It helps reveal whether benchmark scores are trustworthy, comparable, and still useful.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

benchmark-audit 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 8d 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.

Benchmark Audit Strategy

Systematic quality assessment of AI/ML benchmarks using the BetterBench 46-criterion framework, Datasheets for Datasets standards, and established psychometric evaluation principles.

Purpose

Produce a structured quality report for each target benchmark covering: documentation completeness, construct validity indicators, statistical robustness, maintenance status, and known failure modes.

Budget

Resource Floor Target
Benchmarks audited 3 5
Papers read 20 30
Web searches 25 40

State Ledger

<HARD-GATE>
| Metric | Current | Target | Status |
|--------|---------|--------|--------|

</HARD-GATE>

Cannot exit until 80% of all targets met.

Available Tactics

  • artifact-detection — Probe for annotation artifacts and dataset shortcuts

Available SOPs

  • benchmark-inventory — Identify target benchmarks in domain
  • metric-decomposition — Decompose composite metrics into constituent signals
  • contamination-audit — Detect train-test data leakage
  • documentation-audit — Assess documentation completeness (BetterBench/Datasheets)
  • benchmark-synthesis — Produce final structured audit report

Execution Guidance

  1. Inventory Phase: Use benchmark-inventory to identify 5 benchmarks in target domain
  2. Per-Benchmark Loop (repeat for each benchmark): a. Gather benchmark paper, documentation, leaderboard via web searches b. Run documentation-audit against BetterBench 46 criteria c. Run metric-decomposition on primary metric(s) d. Run contamination-audit checking known training corpora e. Run artifact-detection tactic if annotation-based benchmark f. Collect findings into per-benchmark report
  3. Synthesis Phase: Run benchmark-synthesis to produce cross-benchmark comparison

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.

benchmark-audit is a skill published in the GitHub repository yogsoth-ai/de-anthropocentric-research-engine (456 stars, last pushed 2d ago), licensed Apache-2.0. It adds 29 tokens to every session and 902 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.
