What
The built-in skill that explains Claude Code's own configuration now lists the claude plugin subcommands available in the session and whether plugin eval is enabled.
Details
- Its offline reference gained sections on a configurable eval directory, grading of images and binaries by a vision judge, and UTF-16 handling.
- Each of those three sections is marked as describing an upcoming release, not current behaviour.
Evidence
run from a shell, not the prompt
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
Names in the bundleclaude plugin
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Added since
A small documentation edit on Create and distribute a plugin marketplace touched a line naming claude plugin after this was published.
Test your marketplace before sharing. Validation checks file structure; to test whether a plugin changes what Claude does on realistic prompts, run its eval suite with [`claude plugin eval`](/docs/en/plugin-evals) before you publish a new …plugin-marketplaces see the edit
Confirmed since
Anthropic's documentation has since written up claude plugin, on Claude Code changelog.
* Added `--json` to `claude plugin install`, `uninstall`, `update`, `enable` and `disable`, and `errorDetails`/`noteDetails` to each row of `claude plugin list --json`changelog see the edit
