description: Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when the user needs to create a new personal plugin, add optional plugin structure, or generate or update personal or repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata.

### 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`。

# Plugin Creator

## Quick Start

1. Run the scaffold script:

```bash
  # Plugin names are normalized to lower-case hyphen-case and must be <= 64 chars.
  # The generated folder and plugin.json name are always the same.
# Replace <SKILL_DIR> with the verified directory containing this SKILL.md.
# This creates a Codex-format plugin even when run from another agent host.
# By default creates in ~/plugins/<plugin-name>.
python3 <SKILL_DIR>/scripts/create_basic_plugin.py <plugin-name>
```

2. Open `<plugin-path>/.codex-plugin/plugin.json` and replace `[TODO: ...]` placeholders.

3. Generate or update the personal marketplace entry when the plugin should appear in Codex UI ordering:

```bash
# Personal marketplace entries default to ~/.agents/plugins/marketplace.json.
python3 <SKILL_DIR>/scripts/create_basic_plugin.py my-plugin --with-marketplace
```

If the current Git repo already has `.agents/plugins/marketplace.json` and the user has not said
whether the plugin is personal or shared with their team, ask before generating a marketplace entry.
When they choose the repo marketplace, use:

```bash
python3 <SKILL_DIR>/scripts/create_basic_plugin.py my-plugin \
  --path ./plugins \
  --marketplace-path ./.agents/plugins/marketplace.json \
  --with-marketplace
```

4. Generate/adjust optional companion folders as needed:

```bash
python3 <SKILL_DIR>/scripts/create_basic_plugin.py my-plugin \
  --path <parent-plugin-directory> \
  --marketplace-path <marketplace-json-path> \
  --with-skills --with-hooks --with-scripts --with-assets --with-mcp --with-apps --with-marketplace
```

`<parent-plugin-directory>` is the directory where the plugin folder `<plugin-name>` will be created (for example `~/code/plugins`).

## What this skill creates

- Default marketplace-backed scaffolds are personal: `~/plugins/<plugin-name>/` plus
  `~/.agents/plugins/marketplace.json`.
- If the current Git repo already has `.agents/plugins/marketplace.json` and the user has not said
  personal vs team, ask which marketplace to update before generating a marketplace entry.
- Creates plugin root at `/<parent-plugin-directory>/<plugin-name>/`.
- Always creates `/<parent-plugin-directory>/<plugin-name>/.codex-plugin/plugin.json`.
- Fills the manifest with the full schema shape, placeholder values, and the complete `interface` section.
- Creates or updates the selected marketplace when `--with-marketplace` is set.
  - If the marketplace file does not exist yet, seed top-level `name` plus `interface.displayName` placeholders before adding the first plugin entry.
- `<plugin-name>` is normalized using skill-creator naming rules:
  - `My Plugin` → `my-plugin`
  - `My--Plugin` → `my-plugin`
  - underscores, spaces, and punctuation are converted to `-`
  - result is lower-case hyphen-delimited with consecutive hyphens collapsed
- Supports optional creation of:
  - `skills/`
  - `hooks/`
  - `scripts/`
  - `assets/`
  - `.mcp.json`
  - `.app.json`

## Marketplace workflow

- Personal plugins use `~/.agents/plugins/marketplace.json`.
- Repo/team plugins use `<repo-root>/.agents/plugins/marketplace.json`.
- Marketplace root metadata supports top-level `name` plus optional `interface.displayName`.
- Treat plugin order in `plugins[]` as render order in Codex. Append new entries unless a user explicitly asks to reorder the list.
- `displayName` belongs inside the marketplace `interface` object, not individual `plugins[]` entries.
- Each generated marketplace entry must include all of:
  - `policy.installation`
  - `policy.authentication`
  - `category`
- Default new entries to:
  - `policy.installation: "AVAILABLE"`
  - `policy.authentication: "ON_INSTALL"`
- Override defaults only when the user explicitly specifies another allowed value.
- Allowed `policy.installation` values:
  - `NOT_AVAILABLE`
  - `AVAILABLE`
  - `INSTALLED_BY_DEFAULT`
- Allowed `policy.authentication` values:
  - `ON_INSTALL`
  - `ON_USE`
- Treat `policy.products` as an override. Omit it unless the user explicitly requests product gating.
- The generated plugin entry shape is:

```json
{
  "name": "plugin-name",
  "source": {
    "source": "local",
    "path": "./plugins/plugin-name"
  },
  "policy": {
    "installation": "AVAILABLE",
    "authentication": "ON_INSTALL"
  },
  "category": "Productivity"
}
```

- Use `--force` only when intentionally replacing an existing marketplace entry for the same plugin name.
- If the selected marketplace file does not exist yet, create it with top-level `"name"`, an `"interface"` object containing `"displayName"`, and a `plugins` array, then add the new entry.

- For a brand-new marketplace file, the root object should look like:

```json
{
  "name": "[TODO: marketplace-name]",
  "interface": {
    "displayName": "[TODO: Marketplace Display Name]"
  },
  "plugins": [
    {
      "name": "plugin-name",
      "source": {
        "source": "local",
        "path": "./plugins/plugin-name"
      },
      "policy": {
        "installation": "AVAILABLE",
        "authentication": "ON_INSTALL"
      },
      "category": "Productivity"
    }
  ]
}
```

## Required behavior

- Outer folder name and `plugin.json` `"name"` are always the same normalized plugin name.
- Do not remove required structure; keep `.codex-plugin/plugin.json` present.
- Keep manifest values as placeholders until a human or follow-up step explicitly fills them.
- If creating files inside an existing plugin path, use `--force` only when overwrite is intentional.
- Preserve any existing marketplace `interface.displayName`.
- When generating marketplace entries, always write `policy.installation`, `policy.authentication`, and `category` even if their values are defaults.
- Add `policy.products` only when the user explicitly asks for that override.
- Keep marketplace `source.path` relative to the selected marketplace root as `./plugins/<plugin-name>`.
- When the workflow created or updated a marketplace-backed plugin and the current host supports opening Codex deep links, end the final user-facing
  response with a short Codex app handoff. Otherwise provide verified local links to the generated plugin and marketplace manifest and explain that loading this Codex-format plugin requires the target product. Only for the supported Codex handoff, say `To view this in the Codex app:` and write
  `View <normalized plugin name>` and `Share <normalized plugin name>` as Markdown links, not raw
  URLs or code spans.
- The View deeplink uses `codex://plugins/<normalized plugin name>?marketplacePath=<absolute marketplace.json path>`.
  The Share deeplink uses the same URL with `&mode=share`.
- Replace the placeholders with the real normalized plugin name and absolute `marketplace.json`
  path from the scaffolded plugin. URL-encode the path segment and query value when needed.
- Do not add `pluginName` or `hostId` query parameters to these deeplinks. Codex derives both after
  the user clicks the link.
- Do not emit the `View <normalized plugin name>` or `Share <normalized plugin name>` links when no marketplace entry was
  created or updated.

## Validation
