What Makes a Good Tool for Claude Code

Author here. Been thinking a lot on what are the hallmarks of writing tools for Claude Code after reading a this recent blog post (https://www.alephic.com/writing/the-magic-of-claude-code).

Came up with three principles: 1) Wide usage 2) Good documentation 3) Good error messages. Seen this in my own experience while working on Perfetto (perfetto.dev) as well. Curious to see if others are seeing the same.
