Reproducibility Standards

Reproducibility Standards is a skill for Claude Code, Codex from niels-emmer/myace. It costs 27 tokens per session (305 once invoked), scanned A, original, MIT.

A guide for making machine-learning results repeatable from the source code and recorded experiment details alone. It covers random seeds, fixed software versions, runtime environments, data versions, and processing steps.

In plain words
What is it for?
Use it when setting up an ML project or preparing work for handoff to pin dependencies, capture environments, version datasets, record transformations, and verify pipeline outputs.
Why use it?
It reduces differences between runs caused by changing dependencies, random behavior, datasets, or undocumented data-processing steps.

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

Reproducibility Standards 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.

What it actually says

Purpose

Make every result reproducible from source control + logged state alone.

When to use it

Setting up a new project, starting a new experiment, or preparing work for handoff.

Checklist

  • Seed all random generators: numpy, random, torch, tensorflow, and any other stochastic components. Log seeds.
  • Pin dependencies: use lockfiles (requirements.txt, poetry.lock, conda-lock) — not loose version ranges.
  • Capture environment: Dockerfile or conda env.yml that reproduces the exact runtime.
  • Version data: use DVC, hash-based manifests, or snapshot the exact dataset version used.
  • Log transforms: every preprocessing step (scaling, encoding, imputation) must be logged and reproducible.
  • Pipeline DAG: capture the full pipeline graph with input/output hashes per step.

Expected output

A project setup where git clone → install → run reproduces the same results, verified by comparing logged metrics.

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.

Reproducibility Standards is a skill published in the GitHub repository niels-emmer/myace (1 stars, last pushed 4d ago), licensed MIT. It adds 27 tokens to every session and 305 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.
