Claude Code now supports hooks

I've been playing with Claude Code the past few days. It is very energetic and maybe will help me get over the hump on some long-standing difficult problems, but it loses focus quickly. Despite explicit directions in CLAUDE.md to build with "make -j8" and run unit tests with "make -j8 check", I see it sometimes running make without -j or calling the test executable directly. I would like to limit it to doing certain essential aspects of workflow with the commands I specify, just as a developer would normally do. Are "Hooks" the right answer?

For the `-j` issue specifically, exporting `MAKEFLAGS=-j8` should work.

or mcp

Thanks, I'll let Claude know.

The AI definitely gets confused when there is a lot of stuff happening. It helps if you try to make the commands as easy as possible. Like, change 'make' so that '-j8' is default, or add scripts like make-check.sh that does 'make -j check', or add an MCP server that has commands for the most common actions (tell the AI to write an MCP server for you).

Hooks would probably help, I think you could add a hook to auto-reject the bot when it calls the wrong thing.
