Skills Mechanism Guide
What Is an AI Skill, and Why It Matters
A skill is a reusable capability package for AI agents. It combines instruction,
context, and execution patterns, so the agent can reliably perform a class of tasks.
How Skills Work (Mechanism)
- Task trigger: a user request matches a known skill domain (for example, SEO, API design, test generation).
- Instruction loading: the agent loads the skill instructions, rules, and templates.
- Context binding: project files, user constraints, and current environment are injected into execution.
- Structured execution: the agent follows the skill workflow in a deterministic order.
- Output validation: results are checked against quality rules before delivery.
What Skills Actually Do
- Reduce repeated prompting and setup work.
- Improve output consistency across similar tasks.
- Encode best practices so teams can scale quality.
- Lower onboarding cost for new contributors.
- Enable faster iteration with reusable task modules.
Typical Skill Components
- Role definition: what the skill is responsible for.
- Execution checklist: ordered steps and decision gates.
- Constraints: safety, style, or policy requirements.
- Output format: expected structure for final results.
- References: related data sources, tools, or templates.
How to Install Skills (Practical Steps)
- Get a skill package that contains a `SKILL.md` file.
- Place it in your local skills directory (for Codex, under your configured `$CODEX_HOME/skills/...`).
- Keep the folder name stable, because it is often used as the skill id.
- If the skill includes `scripts/`, `assets/`, or `references/`, keep relative paths unchanged.
- Restart your client/session if the runtime caches skill discovery.
How to Use Skills in Real Work
- Invoke directly: mention the skill name in prompt (for example, `$vercel-deploy`).
- Auto-trigger: request a task that matches the skill domain (for example, “deploy this project to Vercel”).
- Pass context: provide repo path, target platform, constraints, and expected output format.
- Validate output: check links, logs, tests, and edge cases before production use.
- Iterate: if output is close but not complete, ask for a second pass with explicit gaps.
Detailed Examples
Example 1: Deploy Website with a Skill
Prompt:
Use $vercel-deploy to deploy this repository and return the production URL.
Repository path: /Users/maqi/code/skills
Requirements: verify homepage works and provide final URL.
Expected result:
- A successful deployment URL.
- Validation output (status code, key route checks).
- Any follow-up actions if environment variables are missing.
Example 2: Extend a Skill Set for a Team
Prompt:
Use $skill-creator to create a new "seo-audit" skill.
Include: checklist, output template, and risk guardrails.
Target: static websites and docs portals.
Expected result:
- A new skill folder with `SKILL.md`.
- Reusable workflow for repeated SEO checks.
- Clear output schema for reports.

Skills 原理说明
什么是 AI Skill,它解决什么问题
Skill 是给 AI 智能体复用的一组能力包,通常包含指令、上下文约束和执行流程,
让智能体在同类任务中更稳定地输出结果。
Skills 的机制原理
- 任务触发:当用户请求命中某个能力域(如 SEO、API 设计、测试生成)时触发。
- 规则加载:智能体读取该 Skill 的规则、步骤和模板。
- 上下文绑定:把项目文件、用户约束、运行环境信息绑定到执行过程。
- 流程化执行:按预定义顺序完成分析、生成、检查等步骤。
- 结果校验:按质量标准验证输出,再返回给用户。
Skills 的作用
- 减少重复提示词编写和初始化成本。
- 提升同类任务输出的一致性和可控性。
- 沉淀最佳实践,便于团队规模化复用。
- 降低新人上手门槛,缩短协作磨合周期。
- 把复杂任务模块化,加快迭代速度。
一个 Skill 通常包含
- 角色定义:这个 Skill 负责什么。
- 执行清单:按顺序执行的步骤和判断条件。
- 约束条件:安全、风格、规范等限制。
- 输出格式:结果应采用的结构和字段。
- 参考资源:可调用的数据源、工具或模板。
Skills 如何安装(实操步骤)
- 获取包含 `SKILL.md` 的技能包。
- 将其放入本地 skills 目录(Codex 常见为 `$CODEX_HOME/skills/...`)。
- 保持目录名稳定,很多系统会把目录名作为 skill 标识。
- 若包含 `scripts/`、`assets/`、`references/`,请保持相对路径不变。
- 如运行时有缓存,重启会话后再验证技能是否可被发现。
Skills 如何使用(工作流方式)
- 显式调用:在提示词里直接写 skill 名称(例如 `$vercel-deploy`)。
- 隐式触发:描述与 skill 强相关任务(例如“把项目部署到 Vercel”)。
- 补全上下文:提供仓库路径、目标平台、约束条件、输出格式。
- 结果校验:检查链接、日志、测试结果、异常分支。
- 二次迭代:若结果接近但不完整,明确指出缺口并要求二次执行。
详细示例
示例 1:使用 Skill 完成部署
提示词:
使用 $vercel-deploy 部署当前仓库,并返回生产环境 URL。
仓库路径:/Users/maqi/code/skills
要求:验证首页可访问,并给出最终链接。
期望产出:
- 可访问的部署 URL。
- 关键校验信息(状态码、核心页面检查结果)。
- 若缺少环境变量,给出后续处理项。
示例 2:给团队新增一个可复用 Skill
提示词:
使用 $skill-creator 新建一个 "seo-audit" skill。
要求包含:检查清单、输出模板、风险边界。
目标场景:静态网站与文档站。
期望产出:
- 新增 skill 目录和 `SKILL.md` 文件。
- 可复用的 SEO 审核流程。
- 结构化报告输出格式。
