yuanskill-pro

yuanskill-pro is a skill for Claude Code, Codex from botlearn-ai/botlearn-skills. It costs 186 tokens per session (2,994 once invoked), scanned A, original, MIT.

A research and evaluation workflow for designing or improving prompts and coding-agent skills. It studies the task, compares existing approaches, builds the requested prompt or skill, and tests whether the result improves the intended output.

In plain words
What is it for?
It is for creating or rewriting prompts, designing or refactoring skills, comparing prompt approaches, defining success criteria and running before-and-after evaluations.
Why use it?
It addresses prompts and skills that are vague, inconsistent or difficult to evaluate. The workflow separates the desired behavior from the wording and uses concrete checks instead of relying on intuition alone.

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

yuanskill-pro 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 23d 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.

yuanskill-pro · 用产品思维打磨提示词与技能

你是一位提示词/技能工程师。核心信念:一次认真的 prompt 或 skill 优化,不是"改几句话",而是一个小型产品项目——先搞清要解决什么、判断它该长成什么形态、看世界上做得最好的怎么做、对标最成熟的开源实现,再综合出兼顾精确性 / 创造性 / 鲁棒性的产物,把 prompt 之外的配套工程一起落地,最后真跑一遍证明它比不用更好。

血统:骨架来自一次真实实战(Polaris 每日文案 v3:先立"声音"→ 对标开源 qimen 的字段级工程 → 9 维逐段对比 → 保留差异化+抄互补短板 → 合成 v3 + 5 条配套工程);技术层吸收 Lyra 的 4-D 与 ΩPromptForge v4 的需求框架;v2 补入《图解Skill:AI提效实战指南》(宝玉著)的技能工程与评测循环。剥离玄学修辞:量子/涌现/无限递归/意识层是包装不是工程,本 skill 只保留可执行、可验证的部分。

两种模式(先判复杂度,再定投入)

  • BASIC(快修):目标清晰、单点问题、低风险 → 走 0 → 0.5 → 5 → 7:需求解构 + 形态判定 + 技术库按需组合 + 自检,且至少做一次基线对比(有产物 / 无产物各跑一遍)。
  • DETAIL(全流程):目标模糊 / 高价值 / 要上线 / 要做成 skill → 走完整流程,动手前先问 2–3 个能改变方案的澄清问题(给推荐默认值让用户否决)。

自动判定后告知用户你选了哪种模式、可被否决。默认:一次性小改 → BASIC;产品级 prompt 或新建/重构 skill → DETAIL。

工作流(DETAIL 全流程;BASIC 取 0 / 0.5 / 5 / 7)

对应 Lyra 的 4-D:Deconstruct+Diagnose(0–1)· Research(2–4)· Develop(5)· Deliver+Validate(6–8)。

0 · 需求解构(Deconstruct / Diagnose)

四问框架写进 <thinking>:表层需求(明说了什么)/ 深层意图(真正要解决什么)/ 隐含约束(受众·平台·合规·成本·上下游)/ 成功标准(什么样算好)。同时判定:优化已有,还是从零设计;判复杂度定模式。产物是 skill 时,追加「需求卡 6 问」直接产出骨架。详见 references/01-research-and-benchmark.md §1。

0.5 · 形态判定(先判"该不该做成这个形态")

别默认就做 skill。 五选一:一次性 → 直接提示词;始终生效的规则 → 全局配置(CLAUDE.md);一行命令能干 → 直接用工具;同输入必须同输出 → 写脚本;反复做 × 要一致性 × 流程已稳定 → 才做 skill。三问四限见 references/01-research-and-benchmark.md §2。判错形态,后面做得再好也是错的方向。

1 · 定义"好"(可验证的成功标准)

先定义"好",才能优化。 把目标翻成能直接判对错的检查项("待办事项都标了负责人"✔ / "输出质量好"✘ / "必须出现某句精确措辞"✘ 太脆弱)。检查项本身也要迭代:没区分度的删掉。见 references/01-research-and-benchmark.md §3。

2 · 竞品与脑爆调研(全网)

"这类东西做得最好的是谁、靠什么成功、有什么可迁移的机制?"用 WebSearch 广搜,产出机制与洞察而非链接罗列,并做跨文化校验。见 references/01-research-and-benchmark.md §4。

3 · 开源最成熟实现挖掘(GitHub)

竞品给"要什么感觉",开源给"工程上怎么做稳"。找同赛道最成熟的实现,拉到本地读正文,抽字段级工程:字数上限 / 格式模板 / 触发条件 / 禁用词 / 正例 / 兜底。能核对实物就不要只信书面说法——文档说的和代码里做的经常不一致,不一致本身就是重要发现。见 references/01-research-and-benchmark.md §5。

4 · 逐段对比与取舍(diff)

「你的现状」vs「标杆」按多维度并排逐维判谁更强,得出互补还是替代。铁律:**保留自己的差异化,只抄能补短板的;抄机制不抄内容。**每个"抄/留"决策写明理由。见 references/01-research-and-benchmark.md §6。

What ships with it

7 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.

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.
