What's Wrong?

Problem

Currently, / slash commands require exact name matching. When I have 30+ skills installed, I need
to remember the full exact name of each skill (e.g., /hugo-aurora-writer) to invoke it. Typing a
partial keyword like /aurora or /writer does not match anything.

This makes the experience frustrating as the number of installed skills grows.

Expected Behavior

When typing / followed by a keyword, I'd expect one of the following:

1. Fuzzy matching — /aurora matches hugo-aurora-writer
2. Substring matching — /writer matches hugo-aurora-writer
3. Autocomplete/filter list — typing /hu shows a filtered list of all skills starting with hu

Any of these would significantly improve the usability of slash commands.

Current Workaround

• Memorize exact skill names
• Run /skills to look up the full name before invoking

Environment

• Claude Code CLI
• 30+ skills installed (project + user + plugin)
• macOS

What Should Happen?

When typing / followed by a keyword, I'd expect one of the following:

1. Fuzzy matching — /aurora matches hugo-aurora-writer
2. Substring matching — /writer matches hugo-aurora-writer
3. Autocomplete/filter list — typing /hu shows a filtered list of all skills starting with hu

Any of these would significantly improve the usability of slash commands.
