Custom slash commands from .claude/commands/ no longer appear in autocomplete (v2.1.88)

Description

After updating to Claude Code v2.1.88, custom slash commands defined in .claude/commands/*.md no longer appear in the autocomplete list when typing / in the prompt.

Steps to reproduce

1. Have custom commands in .claude/commands/ (e.g., session-save.md, daily-tasks.md)
2. Update Claude Code to v2.1.88
3. Type /sess in the prompt — no autocomplete suggestion appears
4. Previously (pre-2.1.88), typing /sess would show session-save in the list

Expected behavior

Custom commands from .claude/commands/ should appear in the slash command autocomplete, as they did in previous versions.

Actual behavior

Only built-in skills (update-config, simplify, loop, schedule, etc.) appear. Custom commands from .claude/commands/ are invisible in autocomplete.

The command files are valid — correct frontmatter, UTF-8 encoding, proper permissions (644). The files haven't changed; only the Claude Code version was updated.

Environment

• Claude Code version: 2.1.88
• OS: macOS (Darwin 25.3.0, arm64)
• Node: v22.12.0
• Shell: zsh
