What issue are you seeing?

After updating to the latest version of codex-cli, the fuzzy search behavior for slash commands seems to be broken. Some commands that should match the typed pattern are not shown in the suggestion list, and the results appear inconsistent.

For example:

Typing /a correctly shows /approvals, /compact, /feedback, etc.

Typing /ac unexpectedly returns no results, even though commands like /feedback, and /compact contain the substring "ac" and used to match in previous versions.

There is no visible error message—only the autocomplete results are missing or inconsistent.

This behavior suggests that the fuzzy-matching logic may have regressed in the latest release.

What steps can reproduce the bug?

Install or update to the latest version of codex-cli.

Open the CLI and start entering a slash command.

Type /a and observe that several matching commands appear (e.g., /approvals, /compact, /feedback).

Then type /ac — expected behavior is that commands containing "ac" should appear, but no suggestions are shown.

Repeat with other partial substrings and note irregular or missing fuzzy-match results.

What is the expected behavior?
