[DOCS] CLAUDE_CODE_PLUGIN_SEED_DIR docs missing multiple directory syntax

Documentation Type

Incorrect/outdated documentation

Documentation Location

https://code.claude.com/docs/en/env-vars

Section/Topic

The CLAUDE_CODE_PLUGIN_SEED_DIR row in the environment variables table and the "Pre-populate plugins for containers" section on the plugin marketplaces page.

Current Documentation

The env-vars page describes CLAUDE_CODE_PLUGIN_SEED_DIR as:

"Path to a read-only plugin seed directory"

The plugin-marketplaces page has a full "Pre-populate plugins for containers" section that uses singular language throughout: "a plugins directory", "point CLAUDE_CODE_PLUGIN_SEED_DIR at this directory", and shows $CLAUDE_CODE_PLUGIN_SEED_DIR/ as a single root.

What's Wrong or Missing?

Changelog v2.1.79 states: "CLAUDE_CODE_PLUGIN_SEED_DIR now supports multiple seed directories separated by the platform path delimiter (: on Unix, ; on Windows)."

Both documentation pages describe this variable as accepting a single directory path. The multiple-directory syntax using platform path delimiters is not documented anywhere. Users who need to combine plugin seeds from multiple sources (e.g., enterprise plugins plus team-specific plugins) have no documented way to do so.

Suggested Improvement

A. Update env-vars page

Change the description from singular to support both forms:

Before:

"Path to a read-only plugin seed directory"

After:

"Path to one or more read-only plugin seed directories. Separate multiple paths with : on Unix/macOS or ; on Windows."

B. Update plugin-marketplaces page

In the "Pre-populate plugins for containers" section, add a subsection or note about multiple directories:

Multiple seed directories: To combine plugins from multiple sources, separate paths with the platform path delimiter: CLAUDE_CODE_PLUGIN_SEED_DIR=/path/to/enterprise-plugins:/path/to/team-plugins

Impact

Medium - Makes feature difficult to understand
