skill-evolution

skill-evolution is a skill for Codex from chuwu57/Chuwu-PR-OS. It costs 90 tokens per session (1,241 once invoked), scanned A, original, MIT.

A maintenance workflow for improving existing skills based on evidence from real tasks, feedback, tests, and an authorised knowledge base. It records proposed changes, their reasons, and how they will be checked.

In plain words
What is it for?
Use it to diagnose gaps in an existing skill, make a small evidence-backed change, verify it, and record what remains uncertain.
Why use it?
It helps distinguish observed problems from guesses and avoids changing skills merely because files are long, numerous, or recently edited.

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

skill-evolution 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 yesterday.

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.

Skill Evolution

归属说明:本Skill由初五维护,属于初五的个人Skill体系。专业依据来自知识库;维护方法来自初五对知识深化与能力转化的任务定义。

目的与入口

让已有Skill在适用场景、证据判断、例外处理和执行效率上变得更成熟。评价对象是实际任务能力;Skill数量、正文长度、链接数量和改动数量均不是成绩。

知识库根目录由使用者明确指定为PR_KNOWLEDGE_ROOT;它必须指向获授权维护的知识库,不能默认为本合集安装目录。先按接入条件核对知识库规则、Skills/registry.yml与Skill进化任务合同。跨工作目录也从该根目录解析知识路径。

默认范围为注册表中Skills/PR/的已有Skill,包括新闻通稿这一PR专业执行能力;视觉、视频、个人内容制作和独立研究Skill不自动加入。用户指定范围优先。首次运行检查当前积累,后续复用已有运行记录,再读发生变化或尚未解决的相关材料。

怎样开始一轮

先看范围内Skill入口、知识调用入口、来源Workflow和实际Feedback/Test-Cases。没有反馈就标明缺口,不补造用户纠正;文件有改动也不等于存在能力问题。

按当前问题经知识库检索工具定位上游知识,只读取会改变诊断的材料。Follow Loop的Radar和运行记录是增量线索,不能自动升级为稳定原则;回到对应知识判断、Evidence与适用边界。无需重新运行Follow Loop或遍历其原始语料。

将证据支持的候选写成进化任务记录:当前问题、知识/反馈依据、预期能力变化、最小落点、验证方法和处置。区分已观察失败、静态连接缺口与待验证假设。优先处理会改变判断、反复返工或制造冲突的问题;允许只有保留或观察项的一轮。

怎样改、怎样验证

  • 专业认识进入Domain;输入输出与决策条件进入Workflow;检索触发、工具适配与执行遗漏进入Skill。已有知识能按需调用时补入口,不复制专业全文。
  • 没有证据支持改动时保留旧版。精简须说明原规则的作用由哪里承接,并用反例检查是否失守。
  • 修改前保存实际工作树中的目标文件、依赖及版本指纹;不得以Git HEAD代替已有未提交版本。写入前复核文件未被其他任务修改。
  • 验证使用任务合同确定的可观察结果。结构检查、受控模拟、真实任务、独立验证分别记录;有限测试只能支持有限结论。参照验证说明准备未提示预期答案的测试输入。
  • 当前任务已授权维护时,完成有依据的小范围修正、验证和记录,不为每个阶段重新确认。知识库边界、案例入库及外部操作沿用用户已有授权;本Skill不扩大权限。

交付与后续使用

每轮交付范围覆盖表与有实质内容的进化任务记录:说明改了什么、保留什么、什么尚待验证,附来源、差异和测试证据。用户产物放当前任务outputs/;可复现回归进入目标Skill的Test-Cases/,真实维护反馈进入Feedback.md。需要跨轮追踪的过程保存在Projects/Skill-Evolution/,不把过程写入知识入口或另造知识总库。

按使用者知识库的注册/索引合同同步确实受影响的登记;运行其现有知识库检查,区分既有问题与本轮问题。Skill真实维护任务完成可登记本Skill的执行记录,但不能据此把所有被审阅Skill升级为真实业务验证或稳定能力。

日常业务调用目标Skill不会自动启动本Skill。下一轮只在用户调用时运行;本Skill自身的修正接受同样的证据和验证要求,不能自行放宽验收来宣称进化成功。

分发版路径与运行条件

先读取依赖说明。本Skill由初五维护;本副本为PROS 05。references/、assets/和scripts/相对本Skill目录解析;Domains/、Skills/前缀从合集根目录解析。包内Markdown链接相对所在文件解析。未附带的个人案例、文献底稿、状态与来源配置只能由使用者提供,不能声称已读取。

本项需要使用者知识库接入;先读知识库接入合同。未接入时仅完成缺口盘点和可完成的只读建议,不运行依赖完整知识库的写回与验收。

What ships with it

3 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.
