Codex Desktop suggests installing GitHub from claude-plugins-official even though github@openai-curated is enabled

What version of the Codex App are you using (From “About Codex” dialog)?

26.423.10653

What subscription do you have?

Pro

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

In Codex Desktop, when I type a prompt containing GitHub, the prompt box shows an inline suggestion saying “为此提示使用 GitHub 插件” / “Use GitHub plugin for this prompt”, with an “Install” button.

Clicking the Install button opens an install dialog for GitHub from claude-plugins-official. The dialog shows:

• Plugin name: GitHub
• Marketplace/source label: claude-plugins-official
• Category: productivity
• Included content: MCP server github

This is confusing because the OpenAI-curated GitHub plugin is already enabled locally.

Relevant local config state:

• github@openai-curated is enabled.
• claude-plugins-official was imported as an additional marketplace.
• The only enabled plugins from claude-plugins-official are context7 and playwright.
• There is no github@claude-plugins-official enabled in my Codex config.

The visible issue is that Codex Desktop recommends installing GitHub from the imported Claude marketplace instead of recognizing or preferring the already enabled github@openai-curated plugin / GitHub app surface.

What steps can reproduce the bug?

1. Open Codex Desktop on Windows.
2. Ensure github@openai-curated is enabled.
3. Import an additional marketplace, for example claude-plugins-official.
4. Ensure no GitHub plugin from claude-plugins-official is enabled.
5. Start a new prompt.
6. Type GitHub.
7. Observe the inline suggestion above the prompt box.
8. Click the suggestion’s Install button.

Observed result:
Codex Desktop opens an install dialog for GitHub from claude-plugins-official, even though github@openai-curated is already enabled.

I could not find an exact duplicate issue. Related but different issues include:

• #18454, about plugin search not matching plugin descriptions.
• #16083, about disabling the built-in GitHub app.

What is the expected behavior?

If github@openai-curated is already enabled, Codex Desktop should not suggest installing another GitHub plugin for the prompt.

If Codex still wants to show a GitHub-related suggestion, it should resolve to the already enabled OpenAI-curated GitHub plugin / GitHub app surface rather than an install prompt for GitHub from claude-plugins-official.

More generally, prompt-box plugin recommendations should take enabled plugin state, marketplace source, and compatibility/ranking into account.

Additional information

This may be an enabled-state detection, marketplace source ranking, or plugin compatibility filtering issue.

I am attaching two screenshots:

1. The prompt box after typing GitHub, showing the inline suggestion “为此提示使用 GitHub 插件” with an Install button.
2. The install dialog opened from that suggestion, showing GitHub from claude-plugins-official, category productivity, and included MCP server github.

The issue is about Codex Desktop UI/recommendation behavior. The OpenAI-curated GitHub plugin itself appears to be installed and enabled.
