A syntax-highlighted Bash tool call in Pi

## Install ```sh pi install npm:@giladbarnea/pi-pretty-bash ``` Start a new Pi session, or run `/reload` in the current session. Every later Bash tool call is highlighted automatically. ## Bash commands and JSON output get syntax colors The extension starts from Pi's complete built-in Bash definition. It highlights the visible command with Pi's Bash colors. After a command finishes, the extension checks its complete output with `JSON.parse()`. Valid JSON gets Pi's JSON colors without reformatting. All other output keeps Pi's built-in rendering. Pi still owns command execution, streaming output, timing, truncation, expansion, and error display. ## Compatibility `pi-pretty-bash` requires Pi `0.83.0` or newer. ## License [MIT](LICENSE)
