DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / Environment variables

CLAUDE_CODE_PLUGIN_ATTRIBUTION

A Claude Code environment variable, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

You can declare where a plugin came from via a JSON file or an environment variable.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.246.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Changelog entries naming it

Documentation pages

None of Anthropic's documentation pages this site has a copy of carries this name.

Names beside it

Every environment variable in the inventory starting claude_code_plugin, up to twelve of them.

CLAUDE_CODE_PLUGIN_BINARY_ASSETSNo description from anybody. 2.1.196 CLAUDE_CODE_PLUGIN_CACHE_DIROverride the plugins root directory. Despite the name, this sets the parent directory, not the cache itself: marketplaces and the plugin cache live in subdirectories under this path. Defaults to ~/.claude/plugins 2.1.138 CLAUDE_CODE_PLUGIN_GIT_TIMEOUT_MSTimeout in milliseconds for git operations when installing or updating plugins (default: 120000).

See [Git operations time out](/docs/en/plugin-marketplaces#git-operations-time-out) 2.1.138 CLAUDE_CODE_PLUGIN_KEEP_MARKETPLACE_ON_FAILURESet to 1 to skip the re-clone attempt and keep using the existing marketplace cache when a git pull fails. Useful in offline or airgapped environments where re-cloning would fail the same way. See [Marketplace updates fail in offline environments](/docs/en/plugin-marketplaces#marketplace-updates-fail-in-offline-environments) 2.1.138 CLAUDE_CODE_PLUGIN_PREFER_HTTPSSet to 1 to clone GitHub owner/repo shorthand sources over HTTPS instead of SSH. Applies to plugin install and update, and to /plugin marketplace add and update. Useful in CI runners, containers, or any environment without a configured SSH key for github.com 2.1.141 CLAUDE_CODE_PLUGIN_SEED_DIRPath to one or more read-only plugin seed directories, separated by : on Unix or ; on Windows. Use this to bundle a pre-populated plugins directory into 2.1.138 CLAUDE_CODE_PLUGIN_USE_ZIP_CACHENo description from anybody. 2.1.138

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the environment variable does. All environment variables.
