eval-report-workflow

eval-report-workflow is a skill for Claude Code from UKGovernmentBEIS/inspect_evals. It costs 57 tokens per session (2,167 once invoked), scanned A, original, MIT.

A workflow for producing a report that measures how well selected AI models perform on an evaluation dataset. It creates result tables, comparisons with a reference result, category breakdowns, token totals, and approximate costs.

In plain words
What is it for?
Use it when you need to run model evaluations and turn their logs into a reproducible report for a README or project record.
Why use it?
It organizes model selection, cost estimation, evaluation runs, and report formatting in one repeatable process.

Written for Claude Code: installed under .claude/. Also seen: positional $N argument.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run python tools/evaluation_report.py src/inspect_evals/<eval_name>/report_config.yaml \.

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

eval-report-workflow 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 2mo 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Make an Evaluation Report

This workflow drives tools/evaluation_report.py, which reads a per-eval report_config.yaml and produces a full reproducible report.md (results table, reference comparison, per-category breakdowns, token totals, approximate cost) plus header-only JSON copies of the input logs under results/. The report_config.yaml, regenerated report.md, and results/ folder are committed alongside the eval's eval.yaml.

Report Formatting

The evaluation report included in the README.md is the rendered report.md produced by tools/evaluation_report.py. It should run on the entire dataset or $5 of compute per model, whichever is cheaper. Use the token count from smaller runs to make this prediction.

A typical rendered report looks like this:

## Reproducibility Information

- Samples: 100 / 100 per model
- Run dates: 2026-04-29
- Versions: inspect_ai=0.3.x, inspect_evals=0.x
- Models: ...
- Total tokens: 1,234,567
- Approximate cost: $0.42 USD (prices as of 2026-04)

Reproduction commands: ...

Register entries: for register entries (register/<name>/eval.yaml), populate the optional evaluation_report block in eval.yaml instead of editing README.md directly — the README is regenerated from the YAML by make check. The block accepts timestamp, a results list (with model, accuracy, and optionally provider, stderr, time, date), and notes. Extra fields at either level are allowed for eval-specific metric columns. See register/README.md for the schema.

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.

eval-report-workflow is a skill published in the GitHub repository UKGovernmentBEIS/inspect_evals (721 stars, last pushed yesterday), licensed MIT. It adds 57 tokens to every session and 2,167 once invoked, about $0.0002 per session on Opus 5.5. 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.
