Claude Code is notably better than Pi, although I wish them the best of luck in their efforts. As https://c-daniele.github.io/en/posts/2026-05-18-coding-harne... notes, "Pi's lightness comes from a default setup that does not survive contact with reality."

The same post on Claude Code: "Even though the System Prompt and tool descriptions are clearly more verbose, most of the extra tokens encode product features and rational design choices: a memory system, scheduled tasks, sub-agents, plan mode, worktree support. Whether those features are worth paying for depends on your needs. Calling the prompt 'bloated' without looking at the whole picture feels wrong to me."

How is text editing in it? This is what I hate about terminal coding UIs the most: all the text editing experience - the basic stuff like moving the cursor around, copying, pasting - is just broken.

I ask Claude to implement non-regression tests. It works like magic. With a couple of modules checking for code quality, more magic. Add some online performance tests if relevant, and it is close to paradise. From time to time, send it to some blog pages and articles with implementation ideas and recommendations. Look for best practices and let it do the analysis and implementation job if it makes sense... T

It is has a lot of javascript. I was forced to make my own for small projects.
