### 导出副本边界与技能别名

迁移、安装、修复和经验回写只作用于当前加载的目标宿主技能副本。原 Codex 技能/MCP、下载的源码和 `original-skills` 均为来源材料，不因执行本副本而写入；只有用户另行明确要求配置 Codex 产品本身时，才按该产品流程处理指定目标。脚本需要安装目录或状态目录时，显式提供目标路径；不得从 `CODEX_HOME` 隐式推断写入位置。

跨技能名称可能沿用源库别名。先查 [技能别名表](../../skill-aliases.json)，优先选择同来源、同插件的条目，再使用其 `id` 调用或读取对应入口；不得假定旧 `$skill`、`superpowers:skill` 名称在新宿主直接注册。不能确定目标时先核对，不替换真实产品命令或 Shell 环境变量。

## 跨宿主使用约定

本副本供支持 Agent Skills 的客户端使用。先检查当前宿主实际提供的工具、权限和已连接服务，再执行正文工作流。原文中的宿主工具标识是能力参考；只有实际发现该工具时才可调用，其他宿主应使用经核验的等价 MCP、CLI 或 API。没有等价能力的步骤必须报告不可用，不能虚构调用或完成状态。

技能资源以本技能目录为基准；输出写入当前项目中用户指定的位置。通过技能名称或自然语言触发，具体快捷命令由宿主决定。涉及真实产品、模型 API、协议字段和官方网址的名称保持原意。授权、审批、隐私和工具范围限制在迁移后仍然有效；不得为兼容而扩大权限。具体依赖与迁移说明见同目录 `PORTABILITY.md`。

# EAS Workflows Skill

Help developers write and edit EAS CI/CD workflow YAML files.

## Reference Documentation

Fetch these resources before generating or validating workflow files. First resolve this skill's directory, then use the fetch script in its `scripts/` directory. It is implemented using Node.js and caches responses using ETags for efficiency:

```bash
# Fetch resources
node <skill-dir>/scripts/fetch.js <url>
```

1. **JSON Schema** — https://api.expo.dev/v2/workflows/schema
   - It is NECESSARY to fetch this schema
   - Source of truth for validation
   - All job types and their required/optional parameters
   - Trigger types and configurations
   - Runner types, VM images, and all enums

2. **Syntax Documentation** — https://raw.githubusercontent.com/expo/expo/refs/heads/main/docs/pages/eas/workflows/syntax.mdx
   - Overview of workflow YAML syntax
   - Examples and English explanations
   - Expression syntax and contexts

3. **Pre-packaged Jobs** — https://raw.githubusercontent.com/expo/expo/refs/heads/main/docs/pages/eas/workflows/pre-packaged-jobs.mdx
   - Documentation for supported pre-packaged job types
   - Job-specific parameters and outputs

Do not rely on memorized values; these resources evolve as new features are added.

## Workflow File Location

Workflows live in `.eas/workflows/*.yml` (or `.yaml`).

## Top-Level Structure

A workflow file has these top-level keys:

- `name` — Display name for the workflow
- `on` — Triggers that start the workflow (at least one required)
- `jobs` — Job definitions (required)
- `defaults` — Shared defaults for all jobs
- `concurrency` — Control parallel workflow runs

Consult the schema for the full specification of each section.

## Expressions

Use `${{ }}` syntax for dynamic values. The schema defines available contexts:

- `github.*` — GitHub repository and event information
- `inputs.*` — Values from `workflow_dispatch` inputs
- `needs.*` — Outputs and status from dependent jobs
- `jobs.*` — Job outputs (alternative syntax)
- `steps.*` — Step outputs within custom jobs
- `workflow.*` — Workflow metadata

## Generating Workflows

When generating or editing workflows:

1. Fetch the schema to get current job types, parameters, and allowed values
2. Validate that required fields are present for each job type
3. Verify job references in `needs` and `after` exist in the workflow
4. Check that expressions reference valid contexts and outputs
5. Ensure `if` conditions respect the schema's length constraints

## Validation

After generating or editing a workflow file, validate it against the schema:

```sh
# Install dependencies if missing
[ -d "<skill-dir>/scripts/node_modules" ] || npm install --prefix <skill-dir>/scripts

node <skill-dir>/scripts/validate.js <workflow.yml> [workflow2.yml ...]
```

The validator fetches the latest schema and checks the YAML structure. Fix any reported errors before considering the workflow complete.

## Answering Questions

When users ask about available options (job types, triggers, runner types, etc.), fetch the schema and derive the answer from it rather than relying on potentially outdated information.
