claude-code - 💡(How to fix) Fix Regression: AskUserQuestion still unavailable in context: fork skills (closed #46654 reoccurring) [4 comments, 4 participants]

Summary

Issue #46654 ("Deferred tools not loaded in context: fork skills") is marked closed/resolved, but the same failure mode is still reproducing on Claude Code 2.1.123.

A skill declaring context: fork with AskUserQuestion in its allowed-tools list does not get the AskUserQuestion schema loaded inside the forked context. The model in the fork either falls back to plain-text questioning or silently skips the call — no error surfaces to the user.

Version

• Claude Code: 2.1.123
• Platform: macOS (darwin 25.3.0)

Reproduction

1. Author a skill with the following frontmatter:

   ---
   name: repro-skill
   context: fork
   allowed-tools:
     - Bash
     - AskUserQuestion
   ---

2. In the skill body, instruct the model to use AskUserQuestion to gather input.
3. Invoke the skill.

Actual: AskUserQuestion is not invoked. The forked agent prints the question as plain text or skips it.

Expected: Per the resolution of #46654, deferred tools listed in allowed-tools should have their schemas auto-loaded in the forked context so the call succeeds.

Workaround in use

Removing context: fork from the affected skill frontmatter. This restores AskUserQuestion behavior but loses the context isolation the field was meant to provide.
