pangu-skill

pangu-skill is a skill for Claude Code, Codex from WhispeRre/pangu. It costs 141 tokens per session (7,464 once invoked), scanned A, original, MIT.

An evaluator and improvement workflow for Claude-compatible agent skills. It scores a skill's instructions, tests the resulting behavior, and uses review checkpoints before keeping changes.

In plain words
What is it for?
Use it to assess a skill, run test prompts, compare revisions, review proposed changes, and keep or revert improvements based on evidence.
Why use it?
It helps find unclear instructions, missing failure handling, and regressions that a simple reading of a skill file may miss.

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

pangu-skill 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/screenshot.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Pangu Skill 1.0

v1.0 · 2026-07-06 — An Agent Skill quality evaluator and validation optimizer built around a 9-dimension rubric, test-prompt validation, git ratchet decisions, and human-in-the-loop checkpoints.

Core idea: evaluate → improve → validate → human confirm → keep or revert → generate result cards. Project identity: pangu-skill.


设计哲学

autoresearch 的精髓:

  1. 单一可编辑资产 — 每次只改一个 SKILL.md
  2. 双重评估 — 结构评分(静态分析)+ 效果验证(跑测试看输出)
  3. 棘轮机制 — 只保留改进,自动回滚退步
  4. 独立评分 — 评分用子agent,避免「自己改自己评」的偏差
  5. 人在回路 — 每个skill优化完后暂停,用户确认再继续

与纯结构审查的区别:不只看 SKILL.md 写得规不规范,更看改完后实际跑出来的效果是否更好


评估 Rubric(9维度,总分100)

设计依据:基于 SkillLens 论文(arXiv 2605.23899)实证发现——LLM-as-judge 评估 skill 质量准确率仅 46.4%(接近随机),加入 meta-skill 三维度后提升到 73.8%。本 rubric 强化 dim3 / dim5 评分标准,新增 dim9「反例与黑名单」,权重平衡到 100。目的:让评分对真实质量更敏感,减少 LLM judge 的乐观偏差。

结构维度(59分)— 静态分析

# 维度 权重 评分标准
1 Frontmatter质量 7 name规范、description包含做什么+何时用+触发词、≤1024字符、禁结尾加"灵活应用/根据情况判断"等空话尾巴
2 工作流清晰度 12 步骤明确可执行、有序号、每步有明确输入/输出
3 失败模式编码 12 必须显式编码失败模式(写出"如果 X 失败 → Y"的明确分支);有fallback路径、错误恢复;只写正向流程而不写失败分支扣 ≥3 分(SkillLens meta-skill 维度)
4 检查点设计 6 关键决策前有用户确认、防止自主失控;检查点必须显性标记(🔴/STOP/CHECKPOINT),仅靠"如果...建议..."措辞不算
5 可执行具体性 17 不模糊、有具体参数/格式/示例、可直接执行;禁止"建议/可以考虑/根据情况/灵活把握/视情况而定"等软化措辞——出现 ≥3 处扣 ≥3 分(SkillLens actionable specificity 维度)
6 资源整合度 4 references/scripts/templates引用正确、路径可达

效果维度(35分)— 需要实测

# 维度 权重 评分标准
7 整体架构 12 结构层次清晰、不冗余不遗漏、与Agent Skill 生态一致;冗余/AI腔废话段落(说白了/换句话说/首先其次综上等AI 套话禁用词)出现一处扣 1 分
8 实测表现 23 用测试prompt跑一遍,输出质量是否符合skill宣称的能力

Meta-skill 维度(6分)— 反例与黑名单

# 维度 权重 评分标准
9 反例与黑名单 6 skill 必须有"不要做什么"的反例清单;只写"应该做 X"没有"不要做 Y"扣 ≥3 分;红灯/危险动作/反模式应单独章节列出(SkillLens risk-action blacklist 维度)

评分规则

  • 维度1-7、9:每个维度打 1-10 分,乘以权重得到该维度得分
  • 维度8(实测表现):跑2-3个测试prompt,按输出质量打1-10分
  • 总分 = Σ(维度分 × 权重) / 10,满分100
  • 改进后总分必须 严格高于 改进前才保留

What ships with it

8 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.
