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

agent-skills CLAUDE.md 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 1mo 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.

Origin

This is a copy

86% identical to addyosmani-agent-skills-zh CLAUDE.md — 65 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

agent-skills

这是 agent-skills 项目,一个面向 AI 编码代理的生产级工程技能集合。

项目结构

skills/       → 核心技能,每个目录一个 SKILL.md
agents/       → 可复用的 agent persona(code-reviewer、test-engineer、security-auditor)
hooks/        → 会话生命周期 hook
.claude/commands/ → Slash commands(/spec、/plan、/build、/test、/review、/code-simplify、/ship)
references/   → 补充检查清单(testing、performance、security、accessibility)
docs/         → 各工具的配置指南

按阶段划分的技能

Define: spec-driven-development
Plan: planning-and-task-breakdown
Build: incremental-implementation、test-driven-development、context-engineering、frontend-ui-engineering、api-and-interface-design
Verify: browser-testing-with-devtools、debugging-and-error-recovery
Review: code-review-and-quality、code-simplification、security-and-hardening、performance-optimization
Ship: git-workflow-and-versioning、ci-cd-and-automation、deprecation-and-migration、documentation-and-adrs、shipping-and-launch

约定

  • 每个 skill 都位于 skills/<name>/SKILL.md
  • 使用带 name 和 description 字段的 YAML frontmatter
  • description 先说明 skill 做什么,再给出触发条件
  • 每个 skill 都应包含:Overview、When to Use、Process、Common Rationalizations、Red Flags、Verification
  • 参考资料放在 references/,不要放在 skill 目录内
  • 只有当内容超过 100 行时,才创建 supporting files

命令

  • npm test:不适用,这个项目本质上是文档项目
  • Validate:检查所有 SKILL.md 是否拥有有效的 YAML frontmatter,并包含 name 与 description

边界

  • Always:新增 skill 时遵循 docs/skill-anatomy.md 的格式
  • Never:不要添加只有泛泛建议、没有可执行流程的 skill
  • Never:不要在 skill 之间复制内容,应该通过引用来复用
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.
