bp-skill-authoring

bp-skill-authoring is a skill for Claude Code, Codex from davidYichengWei/agentic-engineering-framework. It costs 65 tokens per session (1,435 once invoked), scanned A, original, MIT.

A guide for writing and improving Agent Skill files called SKILL.md, including their metadata, structure, and instructions.

In plain words
What is it for?
Use it when creating a skill, revising an existing SKILL.md, or checking rules for skill writing.
Why use it?
It helps keep skills clear, short, consistent, and easy for an agent to use.

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

bp-skill-authoring 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 5d 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.

编写 Agent Skills

语言规范

Skills 使用中文编写,包括:

  • description:中文描述
  • 章节标题和说明:中文
  • 代码示例和标识符:保持英文

YAML Frontmatter

---
name: processing-pdfs                    # 小写,连字符,最多 64 字符
description: 从 PDF 文件中提取文本...      # 中文,第三人称,做什么 + 何时用,最多 1024 字符
---

name 格式:

  • 推荐动名词:processing-pdfs, analyzing-data, testing-code
  • 名词短语也可:pdf-processing, data-analysis
  • ❌ 避免:helper, utils, tools, anthropic-*, claude-*

description 规则:

  • ✅ 使用中文,第三人称:"从 PDF 文件中提取文本"
  • ❌ 避免:"我可以帮你..."、"你可以用这个来..."
  • 包含:做什么 + 何时使用 + 关键词

核心原则

精简至上

只添加 AI 尚不知道的信息:

✅ 好(~50 tokens):
## 锁
使用 TDMutex,不要用 std::mutex:
tdstore::common::TDMutex mutex_;

❌ 差(~150 tokens):
## 锁
线程安全在多线程应用中很重要。
TDStore 使用 bthread 协程,所以需要特殊的锁...

约束条件

  • SKILL.md 正文:< 500 行
  • 引用深度:从 SKILL.md 起只能一层
  • 文件路径:只用正斜杠reference/guide.md

What ships with it

1 file 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.
