+## Field guide
+
+### Top-level fields
+
+- `name` (`string`): Plugin identifier (kebab-case, no spaces). Required if `plugin.json` is provided and used as manifest name and component namespace.
+- `version` (`string`): Plugin semantic version.
+- `description` (`string`): Short purpose summary.
+- `author` (`object`): Publisher identity.
+  - `name` (`string`): Author or team name.
+  - `email` (`string`): Contact email.
+  - `url` (`string`): Author/team homepage or profile URL.
+- `homepage` (`string`): Documentation URL for plugin usage.
+- `repository` (`string`): Source code URL.
+- `license` (`string`): License identifier (for example `MIT`, `Apache-2.0`).
+- `keywords` (`array` of `string`): Search/discovery tags.
+- `skills` (`string`): Relative path to skill directories/files.
+- `hooks` (`string`): Hook config path.
+- `mcpServers` (`string`): MCP config path.
+- `apps` (`string`): App manifest path for plugin integrations.
+- `interface` (`object`): Interface/UX metadata block for plugin presentation.
+
+### `interface` fields
+
+- `displayName` (`string`): User-facing title shown for the plugin.
+- `shortDescription` (`string`): Brief subtitle used in compact views.
+- `longDescription` (`string`): Longer description used on details screens.
+- `developerName` (`string`): Human-readable publisher name.
+- `category` (`string`): Plugin category bucket.
+- `capabilities` (`array` of `string`): Capability list from implementation.
+- `websiteURL` (`string`): Public website for the plugin.
+- `privacyPolicyURL` (`string`): Privacy policy URL.
+- `termsOfServiceURL` (`string`): Terms of service URL.
+- `defaultPrompt` (`array` of `string`): Starter prompts shown in composer/UX context.
+  - Include at most 3 strings. Entries after the first 3 are ignored and will not be included.
+  - Each string is capped at 128 characters. Longer entries are truncated.
+  - Prefer short starter prompts around 50 characters so they scan well in the UI.
+- `brandColor` (`string`): Theme color for the plugin card.
+- `composerIcon` (`string`): Path to icon asset.
+- `logo` (`string`): Path to logo asset.
+- `screenshots` (`array` of `string`): List of screenshot asset paths.
+  - Screenshot entries must be PNG filenames and stored under `./assets/`.
+  - Keep file paths relative to plugin root.
+
+### Path conventions and defaults
+
+- Path values should be relative and begin with `./`.
+- `skills`, `hooks`, and `mcpServers` are supplemented on top of default component discovery; they do not replace defaults.
+- Custom path values must follow the plugin root convention and naming/namespacing rules.
+- This repo’s scaffold writes `.codex-plugin/plugin.json`; treat that as the manifest location this skill generates.
+
+# Marketplace JSON sample spec
+
+`marketplace.json` depends on where the plugin should live:
+
+- Repo plugin: `<repo-root>/.agents/plugins/marketplace.json`
+- Local plugin: `~/.agents/plugins/marketplace.json`
+
+```json
+{
+  "name": "openai-curated",
+  "interface": {
+    "displayName": "ChatGPT Official"
+  },
+  "plugins": [
+    {
+      "name": "linear",
+      "source": {
+        "source": "local",
+        "path": "./plugins/linear"
+      },
+      "policy": {
+        "installation": "AVAILABLE",
+        "authentication": "ON_INSTALL"
+      },
+      "category": "Productivity"
+    }
+  ]
+}
+```
+
+## Marketplace field guide
+
+### Top-level fields
+
+- `name` (`string`): Marketplace identifier or catalog name.
+- `interface` (`object`, optional): Marketplace presentation metadata.
+- `plugins` (`array`): Ordered plugin entries. This order determines how Codex renders plugins.
+
+### `interface` fields
+
+- `displayName` (`string`, optional): User-facing marketplace title.
+
+### Plugin entry fields
+
+- `name` (`string`): Plugin identifier. Match the plugin folder name and `plugin.json` `name`.
+- `source` (`object`): Plugin source descriptor.
+  - `source` (`string`): Use `local` for this repo workflow.
+  - `path` (`string`): Relative plugin path based on the marketplace root.
+    - Repo plugin: `./plugins/<plugin-name>`
+    - Local plugin in `~/.agents/plugins/marketplace.json`: `./plugins/<plugin-name>`
+  - The same relative path convention is used for both repo-rooted and home-rooted marketplaces.
+    - Example: with `~/.agents/plugins/marketplace.json`, `./plugins/<plugin-name>` resolves to `~/plugins/<plugin-name>`.
+- `policy` (`object`): Marketplace policy block. Always include it.
+  - `installation` (`string`): Availability policy.
+    - Allowed values: `NOT_AVAILABLE`, `AVAILABLE`, `INSTALLED_BY_DEFAULT`
+    - Default for new entries: `AVAILABLE`
+  - `authentication` (`string`): Authentication timing policy.
+    - Allowed values: `ON_INSTALL`, `ON_USE`
+    - Default for new entries: `ON_INSTALL`
+  - `products` (`array` of `string`, optional): Product override for this plugin entry. Omit it unless product gating is explicitly requested.
+- `category` (`string`): Display category bucket. Always include it.
+
+### Marketplace generation rules
+
+- `displayName` belongs under the top-level `interface` object, not individual plugin entries.
+- When creating a new marketplace file from scratch, seed `interface.displayName` alongside top-level `name`.
+- Always include `policy.installation`, `policy.authentication`, and `category` on every generated or updated plugin entry.
+- Treat `policy.products` as an override and omit it unless explicitly requested.
+- Append new entries unless the user explicitly requests reordering.
+- Replace an existing entry for the same plugin only when overwrite is intentional.
+- Choose marketplace location to match the plugin destination:
+  - Repo plugin: `<repo-root>/.agents/plugins/marketplace.json`
+  - Local plugin: `~/.agents/plugins/marketplace.json`
