[BUG] Slash command autocomplete shows only ~5 built-in commands, hides all 78 custom skills (regression from #22020)

What's Wrong?

The / slash command autocomplete dropdown in Claude Code Desktop app (v2.1.109, Windows 11) only shows ~5 built-in commands (schedule, btw, rewind, clear, export). None of my 78 custom skills from ~/.claude/skills/ appear in the picker.

This worked correctly ~9 hours ago (same machine, same skills directory). The list also loads incrementally — first shows 3 items, then 2 more appear after a moment — suggesting an async loading issue with a premature cutoff.

Skills themselves work fine when invoked by typing /skill-name manually in a message — the model picks them up via the Skill tool. The issue is only with the autocomplete UI.

This appears to be a regression of #22020 (fixed in Feb 2026), where having ~50+ custom skills caused built-in commands to disappear from autocomplete. The original fix may have been lost or broken by recent changes.

Setup:

• ~/.claude/skills/ contains 79 directories, 78 with valid SKILL.md files
• - Each SKILL.md has proper frontmatter (name, description, version, category, tags, etc.)
• - - Skills are loaded into the system prompt correctly (visible in conversation context)

What Should Happen?

The / autocomplete dropdown should list ALL discovered skills — both built-in commands and custom skills from ~/.claude/skills/. This worked correctly before the recent update. With 78 custom skills, all should appear in a scrollable/filterable list, same as they did 9 hours ago.

Error Messages/Logs

Steps to Reproduce

1. Create 50+ custom skills in ~/.claude/skills/ (each as skill-name/SKILL.md with valid frontmatter)
2. 2. Open Claude Code Desktop app (v2.1.109)
3. 3. In the chat input, type /
4. 4. Observe the autocomplete dropdown

Expected: All custom skills + built-in commands appear in a scrollable list
Actual: Only ~5 built-in commands appear (schedule, btw, rewind, clear, export). Custom skills are completely missing from the dropdown. The list loads asynchronously — first 3 items, then 2 more after a brief delay.

Note: Typing /skill-name directly in a message and sending it works — the model correctly invokes the skill via the Skill tool. The issue is isolated to the autocomplete UI.

Workaround: Typing /skill-name in the message body works — skills are correctly loaded into the system prompt and the Skill tool invokes them. Only the autocomplete UI is broken.
