What's Wrong?

after rewinding, claude loses skills should be already registered.

What Should Happen?

claude should report the installed skills, just like fresh session.

Error Messages/Logs

this is the correct output with a fresh session:


❯  what skills do you have, and where are they defined?

⏺ Here are the skills available, as listed in the system prompt:

  Other skills:
  - keybindings-help — Customize keyboard shortcuts

  Let me find where they're defined on disk.



this is the incorrect output after rewind:


❯ what skills do you have, and where are they defined?

∴ Thinking…

  The user is asking about what skills I have available and where they're defined. Let me check for any skill definitions in the project.

⏺ CL, I don't have any custom skills defined. There are no skill files in either:

  - .claude/skills/ (project-level)
  - ~/.claude/skills/ (user-level)
  - .claude/commands/ (legacy location)

  Skills are user-defined prompt templates that can be invoked via /skillname. They're typically defined as markdown files in .claude/skills/ (project-scoped) or ~/.claude/skills/
  (global). Each file becomes a slash command.

  The only built-in slash commands I have are the standard Claude Code ones like /help, /clear, /compact, etc. — those aren't skills, they're CLI builtins.

  Want me to create any skills for this project?

Steps to Reproduce

1. Start a fresh claude session and ask: what skills do you have
2. /rewind to go back to the first conversation: "what skills do you have"
3. enter to send the message.

step 1 shows the correct skills registry, but step 3 shows just the basic skills
