best-skills is a collection of reusable skills for coding agents, including tools for writing papers, creating diagrams and presentations, generating code documentation, and other tasks. Users install its skills into agents such as Cursor, Claude Code, Codex, or OpenClaw so those agents can recognize relevant requests and run the corresponding workflows. The catalogue entries are examples of the skills included in the collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.00722 |
| Opus 5 | $0.00036 | $0.00361 |
| Sonnet 5 | $0.00014 | $0.00144 |
| Haiku 4.5 | $0.00007 | $0.00072 |
Grade A, and why
skill-prompt-convert 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 13d 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
Skill 与 Prompt 互转
使用时机
- 用户需要将 Skill 转为可直接复制到聊天框的 Prompt
- 用户需要将 Prompt 转为 SKILL.md 格式的 Skill
- 用户提到 Skill 与 Prompt 互转、格式转换
Step 1：获取输入并确认方向
从用户消息或粘贴/附件中获取待转换内容，判断方向：
- A. Skill → Prompt：输入为 SKILL.md 内容，输出聊天框可用的 Prompt
- B. Prompt → Skill：输入为 Prompt 内容（含 ``` 代码块），输出 SKILL.md 格式
Step 2：执行转换
Skill → Prompt 时：将 name、description 融入 # Role 和 # Task；将「使用时机」转化为适用场景；将 Step 1/2... 转化为 # Workflow 或 # Constraints；补充 # Output Format 和 # Input 占位符；输出用 ``` 包裹。
Prompt → Skill 时：从 # Role、# Task 提炼 name（英文小写短横线）和 description；从 # Task 或 # Constraints 提炼「使用时机」；将 # Workflow、# Constraints 拆解为 Step 1、Step 2...；保留 # Output Format 到「注意事项」；输出完整 SKILL.md，必须符合标准 Skill 格式。
Step 3：输出结果
- Part 1 [转换说明]：简要说明映射关系（如：Step 1 映射为 Workflow 第一步）
- Part 2 [转换结果]：完整的转换后内容（可直接粘贴使用）
注意事项
- 信息零丢失：不得删减核心逻辑、步骤、约束条件
- 格式适配：Skill 强调「何时触发」「Agent 如何执行」；Prompt 强调「用户输入什么」「输出什么格式」
- 命名规范：
name必须英文、小写、短横线（如wechat-article-writer）；reference 文件名同理（如outline-review-science.md） - description 质量：需包含「什么时候用」「用来干什么」及关键词
- Skill 正文结构：标题 → 使用时机 → Step 1/2... → 注意事项/示例；多输入任务需补充「触发时的输入方式」
- 标准 Skill 格式：YAML 前置元数据必须用
---开头和结尾闭合，使用name:和description:（严禁## name:），示例：--- name: skill-name description: 触发场景与功能描述 --- # 标题 ...
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.

skill-prompt-convert is a skill published in the GitHub repository xstongxue/best-skills (2,814 stars, last pushed 18d ago), licensed Apache-2.0. It adds 72 tokens to every session and 722 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
