experiment-readout

experiment-readout is a skill for Claude Code, Codex from nexu-io/html-anything. It costs 31 tokens per session (778 once invoked), scanned A, original, Apache-2.0.

A structured report template for product experiments such as A/B tests, where two or more versions are compared using measured results. It covers the hypothesis, setup, metrics, results, interpretation, decision, and follow-up tests.

In plain words
What is it for?
Use it to decide whether to launch, change, continue, or stop an experiment involving product changes, pricing, onboarding, feature rollouts, or email variants.
Why use it?
It helps separate reliable signals from noise or unknowns and makes caveats visible when samples are small, data is incomplete, or results are not conclusive.

About the project

html-anything is a local AI-assisted HTML editor in which coding-agent command-line tools create documents such as articles, presentations, posters, prototypes, and reports from reusable templates. People use it to produce HTML and export it to services such as WeChat, X, and Zhihu or to HTML and PNG files. The catalogue entries are the skills and instructions that define its output surfaces and workflows.

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

experiment-readout 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 9d 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

【模板: 实验复盘 / Experiment Readout】 【意图】这不是普通数据报告、不是 dashboard。目标是回答: "这个实验说明了什么, 我们下一步应该上线、停止、继续跑, 还是重新设计?"

【适合输入】

  • A/B test、增长实验、定价实验、onboarding 改版、功能灰度、邮件实验
  • 可以是 markdown、CSV、表格粘贴或混合记录

【必须输出的结构】

  1. Header: 实验名称、owner、日期、实验状态、decision。
  2. Hypothesis: 原始假设, 必须改写成可验证句式。
  3. Setup: audience、variant、duration、sample size、primary metric、guardrail metrics。
  4. Result snapshot: primary metric lift、absolute delta、sample、confidence / caveat。
  5. Metric table: Control vs Variant, primary + secondary + guardrail。
  6. Interpretation: 解释结果为什么发生, 区分 signal、noise、unknown。
  7. Decision: Ship / iterate / extend / stop 四选一, 并给理由。
  8. Follow-up experiments: 2-4 个下一步实验, 每个包含 hypothesis、expected impact、effort。
  9. Instrumentation notes: 数据缺口、埋点问题、样本偏差。

【设计要求】

  • 产品数据团队风格: 清楚、可信、行动导向。
  • 首屏必须有大号 decision badge 和 primary metric delta。
  • 图表可以用 CSS/SVG/Chart.js; 如果用 Chart.js, canvas 外层必须固定高度。
  • 不要把结果包装得过度确定; 小样本或缺少显著性时必须明确 caveat。

【可选风格模板 — 参考 assets/】 根据实验语境选择一种, 不要三种混用:

  • assets/product-readout.html: 默认风格。浅色产品实验复盘, 适合 PM / growth / leadership readout。
  • assets/lab-notebook.html: 研究实验室 notebook, 适合 early-stage experiment、定性 + 定量混合、需要保留 caveat 的探索实验。
  • assets/growth-console.html: 深色 growth analytics console, 适合增长团队、实时指标、漏斗 / activation / conversion readout。

如果用户没有指定风格, 优先使用 product-readout; 如果材料强调研究过程和不确定性, 使用 lab-notebook; 如果材料强调增长指标、漏斗、实时监控或运营节奏, 使用 growth-console

【内容真实性】

  • 只使用用户提供的数据。不要捏造 p-value、confidence、样本量。
  • 如果没有统计显著性信息, 用 "directional" / "inconclusive" / "needs more data" 表达。

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
