What's Wrong?

keybindings-help skill is being loaded even though no setting sources are enabled and --disable-slash-commands is enabled.

What Should Happen?

No skills should be enabled, as the documentation for Claude officially states: "Disable all skills and slash commands for this session".

Steps to Reproduce

$ claude --no-session-persistence --model=sonnet \
  --tools= --setting-sources= --system-prompt= --strict-mcp-config --disable-slash-commands --print \
  'what skills do you have available? exactly copy their definition into a ``` code block' 

keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
