Section/Topic

plugin.json manifest schema and plugin dependency installation behavior for /reload-plugins and marketplace auto-update

Current Documentation

The docs currently say:

The .claude-plugin/plugin.json file defines your plugin's metadata and configuration. This section documents all supported fields and options.

{
  "name": "plugin-name",
  "version": "1.2.0",
  "description": "Brief plugin description",
  "author": {
    "name": "Author Name",
    "email": "author@example.com",
    "url": "https://github.com/author"
  },
  "homepage": "https://docs.example.com/plugin",
  "repository": "https://github.com/author/plugin",
  "license": "MIT",
  "keywords": ["keyword1", "keyword2"],
  "skills": "./custom/skills/",
  "commands": ["./custom/commands/special.md"],
  "agents": "./custom/agents/",
  "hooks": "./config/hooks.json",
  "mcpServers": "./mcp-config.json",
  "outputStyles": "./styles/",
  "lspServers": "./.lsp.json",
  "monitors": "./monitors.json"
}

The plugin discovery docs also say:

When you install, enable, or disable plugins during a session, run /reload-plugins to pick up all changes without restarting:

/reload-plugins

Claude Code reloads all active plugins and shows counts for plugins, skills, agents, hooks, plugin MCP servers, and plugin LSP servers.

And the marketplace docs say:

Claude Code can automatically update marketplaces and their installed plugins at startup. When auto-update is enabled for a marketplace, Claude Code refreshes the marketplace data and updates installed plugins to their latest versions. If any plugins were updated, you'll see a notification prompting you to run /reload-plugins.

What's Wrong or Missing?

A. Plugin dependency declarations are undocumented

The plugin manifest reference says it documents all supported plugin.json fields, but it does not describe any field or syntax for declaring plugin dependencies.

B. Dependency auto-install behavior is undocumented

The docs for /reload-plugins and marketplace auto-update explain reload/update at a high level, but they do not say these flows can now auto-install missing plugin dependencies from marketplaces the user has already added.

C. The prerequisite is missing

The changelog entry for v2.1.116 makes the scope explicit: dependency auto-install only works for dependencies resolvable from marketplaces that are already configured. The current docs do not explain that prerequisite or what users should expect when a required marketplace has not been added yet.

Suggested Improvement

Add a dedicated Plugin dependencies subsection to plugins-reference that documents:

1. Which plugin.json field(s) declare plugin dependencies
2. The expected schema for those declarations
3. How Claude Code resolves dependencies across configured marketplaces
4. What happens during /plugin install, /reload-plugins, and background marketplace auto-update when a dependency is missing
5. What happens when the dependency's marketplace has not been added yet

Then update the user-facing workflow docs to mention the new behavior:

• discover-plugins: note that /reload-plugins can auto-install missing dependency plugins
• plugin-marketplaces: note that startup auto-update can auto-install missing dependency plugins from already-added marketplaces
• commands: expand the /reload-plugins entry so users know it may install required dependency plugins in addition to reloading active plugins

Impact

Medium - Makes feature difficult to understand

Issue #51370 Verification

Title: [DOCS] Plugin docs missing dependency auto-install behavior for /reload-plugins and marketplace auto-update
Issue Date: 2026-04-20
Verification Date: 2026-05-01
Status: RESOLVED

Issue Summary

This issue reports that plugin documentation is missing information about:

1. The dependencies field in plugin.json manifest schema for declaring plugin dependencies
2. Dependency auto-install behavior during /reload-plugins and marketplace auto-update
3. The prerequisite that dependency auto-install only works for marketplaces the user has already configured

---

Verification Results

Claim 1: plugin.json schema does not document dependency declaration fields

Status: RESOLVED

At https://code.claude.com/docs/en/plugins-reference, lines 390-394 show the complete schema example that includes the dependencies field:

```json
{
  "name": "plugin-name",
  "version": "1.2.0",
  "description": "Brief plugin description",
  ...
  "dependencies": [
    "helper-lib",
    { "name": "secrets-vault", "version": "~2.1.0" }
  ]
}
```

And line 437 documents the field:

Field	Type	Description	Example
dependencies	array	Other plugins this plugin requires, optionally with semver version constraints. See Constrain plugin dependency versions	[{ "name": "secrets-vault", "version": "~2.1.0" }]

Verdict: The schema reference now documents the dependencies field completely.

Claim 2: Dependency auto-install behavior is undocumented for /reload-plugins and marketplace auto-update

Status: RESOLVED

At https://code.claude.com/docs/en/plugin-dependencies, line 11:

When you install a plugin that declares dependencies, Claude Code resolves and installs them automatically and lists which dependencies were added at the end of the install output. If a dependency later goes missing, /reload-plugins and the background plugin auto-update reinstall it, provided its marketplace is already in your configured marketplaces.

This explicitly covers the auto-install behavior during /reload-plugins and marketplace auto-update, including the prerequisite about configured marketplaces.

Verdict: The dependency auto-install behavior is fully documented.

---

Claim 3: The prerequisite that auto-install only works for already-configured marketplaces is missing

Status: RESOLVED

At https://code.claude.com/docs/en/plugin-dependencies, line 11 (same quote as above):

If a dependency later goes missing, /reload-plugins and the background plugin auto-update reinstall it, provided its marketplace is already in your configured marketplaces.

And line 11 further clarifies:

Dependencies from a marketplace you have not added are left unresolved.

Verdict: The prerequisite is clearly documented.

---

Current State

Claim	Status
plugin.json schema documents dependencies field	RESOLVED
Dependency auto-install behavior documented	RESOLVED
Prerequisite about configured marketplaces documented	RESOLVED

---

Suggested Fix

N/A - issue has been resolved.

Conclusion & Recommendation

Primary Concern: Plugin docs missing dependency auto-install behavior for /reload-plugins and marketplace auto-update

Resolution Status: RESOLVED

Recommendation: CLOSE

The documentation now fully addresses all three claims in the issue. The plugin.json schema reference documents the dependencies field (lines 390-394, 437 of plugins-reference), the plugin-dependencies page documents the auto-install behavior and its prerequisite (line 11), and the discover-plugins page notes that install output lists auto-installed dependencies (line 276). All four affected pages listed in the issue have been updated to cover the new behavior.
