skill-scorer

skill-scorer is a skill for Claude Code, Codex from AndrewNgGirl/SkillLens. It costs 95 tokens per session (2,521 once invoked), scanned A, original, MIT.

A review tool for Agent Skills, which are instruction files that guide coding agents. It supports skills made for Cursor, Claude, and OpenClaw.

In plain words
What is it for?
Use it to grade, audit, lint, or improve a SKILL.md file, skill folder, or skill archive.
Why use it?
It gives a consistent score and evidence-based review instead of relying only on personal judgment. It also points out specific ways to improve a skill.

Which agent this was written for is unclear — built for openclaw. Also seen: built for openclaw.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 skills/skill-scorer/scripts/score.py --agent-wizard <path-to-skill-zip-dir-or-SKILL.md>.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file 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.

Fable 5.1 $0.00095 $0.02521
Opus 5 $0.00048 $0.01260

Security

Grade A, and why

skill-scorer 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

skill-scorer

一个"评测 Skill 的 Skill"。接收任意 Agent Skill 的源文件,必须依据本仓库的官方评分入口和 rubric/rubric.yaml 给出 5 大支柱的 100 分制评分、等级、证据引用与改进建议。Rubric 内置三类型差异化(atomic / pipeline / composite),子维度数随 skill 结构自动启用,由 applies_to 字段控制。同时兼容 Cursor / Claude / OpenClaw 三套规范。

When to use

  • 用户提供 SKILL.md / skill 文件夹 / .zip / GitHub URL,并请求评分、审计或改进建议。
  • 用户询问"我这个 skill 写得怎么样"、"怎么提升我的 skill 质量"、"帮我对齐官方最佳实践"。
  • 不适用于:评价非 Skill 类文档(普通 README / 博客 / prompt 模板)。

Code Agent Quick Start

如果你是 Cursor、WorkBuddy、Hermes、小龙虾或类似 code agent,先读 USAGE.md

推荐先运行 CLI 向导,让用户选择通用评测或金融专家版;如果选择金融专家版,向导会继续确认金融子场景,并输出后续官方命令:

python3 skills/skill-scorer/scripts/score.py --agent-wizard <path-to-skill-zip-dir-or-SKILL.md>

规则分预览:

python3 skills/skill-scorer/scripts/score.py <path-to-skill-zip-dir-or-SKILL.md>

完整 agent-side Deep Review(使用 code agent 自己的模型套餐,不消耗 SkillLens 服务端 key):

python3 skills/skill-scorer/scripts/score.py --agent-prompt <path-to-skill-zip-dir-or-SKILL.md> > agent-deep-review-prompt.md
# 将 agent-deep-review-prompt.md 完整交给当前 code agent 的模型,保存严格 JSON 为 agent-llm-results.json
python3 skills/skill-scorer/scripts/score.py --llm-results agent-llm-results.json <path-to-skill-zip-dir-or-SKILL.md>

不得临时生成自定义评分脚本替代官方 CLI;最终分数必须来自最后一步官方 CLI 输出。

金融专家版(可选)应优先通过 --agent-wizard 选择;手动执行时,必须在 --agent-prompt--llm-results 两步都加入相同的 --domain finance --scenario <scenario-id>。支持的场景详见 USAGE.md

Inputs

  • 一个 SKILL.md 文本,或
  • 一个 skill 目录(含 scripts/ references/ assets/ 等),或
  • 一个 .zip 打包的 skill,或
  • 一个指向 skill 仓库/子目录的 GitHub URL(Web 工具侧支持)。

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.
