Description (problem / solution / changelog)

Problem

When using the / command in Gemini CLI to invoke a skill, pressing Enter after selecting a skill from the autocomplete dropdown does nothing. The CLI silently ignores the keypress and the skill is never triggered.

Steps to reproduce

1. Type / in the Gemini CLI prompt — the dropdown shows available skills
2. Use arrow keys to navigate and select a skill
3. Press Enter to run the selected skill

Workaround: Manually delete the last character of the inserted skill name and retype it — after this, Enter works as expected.

Root Cause

When the user navigates the suggestion dropdown with arrow keys, hasUserNavigatedSuggestions.current is set to true. When Enter is pressed to select a skill, handleAutocomplete inserts the skill name into the buffer — but hasUserNavigatedSuggestions.current was never reset in the default autocomplete code path.

On the subsequent Enter press (intended to execute the skill), the isPerfectMatch fast-path in InputPrompt.tsx evaluates:

   if (
     completion.isPerfectMatch &&
     keyMatchers[Command.SUBMIT](key) &&
     recentUnsafePasteTime === null &&
     (!(completion.showSuggestions && isShellSuggestionsVisible) ||
       (completion.activeSuggestionIndex <= 0 &&
         !hasUserNavigatedSuggestions.current))  // ← still true from arrow-key navigation!
   ) {
     handleSubmit(buffer.text);
   }

Since hasUserNavigatedSuggestions.current was still true, the condition short-circuits to false. Enter falls through to the ACCEPT_SUGGESTION handler, which calls handleAutocomplete again (a no-op since the text is already complete), and the keypress is effectively swallowed.

│ This also explains the workaround: deleting and retyping a character triggers a non-navigation keypress, which resets hasUserNavigatedSuggestions.current = false, allowing the next Enter to work.

Fix

Reset hasUserNavigatedSuggestions.current = false immediately after the default handleAutocomplete call in the ACCEPT_SUGGESTION handler. This mirrors what the shell mode path already does correctly.

                 // Default behavior: auto-complete to prompt box
                 completion.handleAutocomplete(targetIndex);
                 setExpandedSuggestionIndex(-1); // Reset expansion after selection
   +             hasUserNavigatedSuggestions.current = false;
