Rider AI Chat shows both commands and skills in "/" autocomplete menu #35564

Description

When using OpenCode in Rider AI Chat and typing / to access the command autocomplete menu, both commands and skills are displayed together. This is incorrect behavior.
Expected Behavior: Only custom commands (defined in .opencode/commands/) should appear when typing /. Skills should not be displayed in this menu, as they are meant to be loaded on-demand via the skill tool used by agents.
Actual Behavior: Both commands and skills are shown together in the same autocomplete list, which is confusing for users.

Note: This issue is specific to the Rider integration. When using the OpenCode terminal (TUI), the behavior is correct—only commands are displayed
