ccline: AI at the zsh prompt — for benchmark-minded terminal power users

[jianshuo]

Hey hyperfine community! ⏱️

If you're using hyperfine to benchmark your shell commands, you're clearly a terminal power user who cares about precision. I built something that adds AI to the shell itself.

It's ccline — natural language at the zsh prompt.

What it does

ccline hijacks zsh's command_not_found_handler. Type something that isn't a real command — plain English, a question — and it asks Claude AI. Answer renders as Markdown. Press Enter to run.

$ benchmark two implementations of the same command
→ hyperfine 'cmd1' 'cmd2' --warmup 3
→ [press Enter to run]

$ run benchmark with export to markdown table
→ hyperfine --export-markdown results.md 'your-command'
→ [press Enter to run]

$ find the fastest way to count lines in a large file
→ [Claude compares wc -l, ripgrep, awk approaches]

When you need a quick answer before deciding what to benchmark — ccline is there.
