evidence-first-engineering

evidence-first-engineering is a skill for Claude Code, Codex from NocodeMrLi/mini-program-engineering-skill-suite. It costs 130 tokens per session (638 once invoked), scanned A, original, MIT.

A general engineering guide for software built by coding agents. It requires conclusions and progress reports to match the available evidence, with clear boundaries, checks, approvals, and recovery information.

In plain words
What is it for?
Use it to structure project discovery, implementation plans, verification reports, release checklists, risk reviews, and public sharing of sensitive project information.
Why use it?
It reduces unsupported claims and uncontrolled changes during development. It makes it clearer what is known, what was changed, what was tested, and what remains uncertain.

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

evidence-first-engineering 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 5d 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

/evidence-first-engineering — 证据优先工程基础

本技能是领域无关的工程治理基础:任何领域的 Agent 软件工程套件都可以 vendored 引用本层,再叠加自己的领域事实与平台规则。第一个垂直应用是小程序工程开发套件(mini-program-engineering-suite)。

核心组件

使用方式(对垂直套件作者)

  1. foundation/ 目录整体 vendored 到你的套件,或以相对链接引用(单仓场景)。
  2. 你的领域 Skill 引用上述文档作为门禁与状态语言,不复制正文。
  3. 领域易变事实(平台规则等)放你自己的事实层,并遵循「执行层即时查官方、内容层受控进化」的保鲜原则。
  4. 引用本层时保留 foundation-source 标记,便于升级时同步。

输出契约(继承,不变)

阶段性或最终汇报至少包含:当前结论与阶段;已完成的动作及证据;未执行、未验证或待确认项;改动边界与残余风险;下一步动作。状态词使用证据状态模型;没有对应证据时诚实标注 unknown,不夸大。

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.
