So, are you saying that skills are not such a good tool for agents to learn, they still need tool-trial-and-error dance after injecting them? (I'm assuming each tool comes with its own skill.)

It honestly depends on the model. For my pi-brains extension for pi

https://github.com/gitsense/pi-brains

I've found after the first hook injection they get it, but there are occasions it can forget, but since everything is driven by hooks, you can inject as often as needed.

The issue with skills is, they are a one time thing, so you really can't use skills to correct haviorial issues.

I do not need to waste tokens on skills, I use Claude Code hooks.

Have a look at the TDD guard at https://codeleash.dev - the scripts/tdd_log.py arguments are pretty specific but it also has guidance in CLAUDE.md and lots of helpful error messages.
