DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
The slash command system now properly propagates the shouldQuery flag from command handlers. This allows custom commands to control whether their output should trigger a follow-up query to Claude.
Example usage:
# Custom commands can now return both messages and control query behavior
/my-command some arguments
# The command can decide whether Claude should process the result further
