Hook Intercept & Slash Command Pattern FAQs

Question 1

Is Go required to implement this skill?

Accepted Answer

The specific implementation examples provided are in Go, but any language capable of reading from stdin and writing JSON to stdout can implement the Claude Code hook protocol.

Question 2

Will my custom commands appear in the /help menu?

Accepted Answer

Yes. By creating a markdown stub file in the commands directory, Claude Code will automatically discover your command and display it in the help menu, even if the logic is handled by a hook.

Question 3

Can I pass arguments to commands using this pattern?

Accepted Answer

Yes. The pattern uses regex matching in the handler to capture user-provided arguments, allowing for complex command structures like /command .

Question 4

Why use this pattern instead of letting Claude handle the command?

Accepted Answer

It provides three main benefits: it's significantly faster because it skips the LLM round-trip, it's free because it uses no tokens, and it's deterministic, meaning it provides the exact same output every time.

Question 5

What does 'decision: block' mean in this context?

Accepted Answer

In the Claude Code hook API, 'block' is a success state. It indicates that the hook has fully handled the user's request and the prompt should not be sent to the Claude API, saving time and tokens.
