Tips suggest installing skills/plugins already installed in project

Description

The tips system in Claude Code suggests installing skills/plugins that are already installed in the current project. For example, it suggested /plugin install frontend-design@claude-plugins-official when frontend-design is already an active skill in the project.

Expected behavior

Tips should check the project's existing skills/plugins before suggesting installs, and suppress tips for things already present.

Steps to reproduce

1. Have a project with skills installed (e.g., frontend-design)
2. Use Claude Code normally in a terminal
3. Observe tips suggesting you install skills you already have

Environment

• Claude Code CLI
• macOS
