❯ Here is the secret word: BOUGAINVILLEA

⏺ Acknowledged. How can I help you?

❯ /claude-skill-fork
  ⎿  The skill file itself contains the question "What is the secret word the user provided?" but does not contain any secret
     word. There is no secret word provided in any of the available context -- neither in the skill file, the CLAUDE.md
     instructions, nor anywhere else in the conversation. I don't have a secret word to report.

❯ Try forking.

⏺ Let me read the skill file first.

⏺ Read 1 file (ctrl+o to expand)

⏺ Skill(claude-skill-fork)
  ⎿  Done

⏺ The forked skill couldn't find the secret word because it doesn't have access to the conversation context — it only sees the
  skill file and project files. The secret word "BOUGAINVILLEA" was provided in the conversation, which the fork can't see.

  This demonstrates a limitation of forked skill execution: the forked context is isolated from the parent conversation
  history.
