cc-boost is an open-source Claude Code plugin that reduces token consumption by filtering noisy tool output before it reaches the context window. It strips ANSI escape codes, collapses repetitive npm/pip progress bars into single summary lines, and folds consecutive node_modules stack frames into compact summaries — typically achieving 60–90% character reduction on verbose command output. It also intercepts interactive scaffold commands (create-next-app, vite, sveltekit, remix, angular) that Claude cannot run interactively, prompting Claude to ask the user for configuration choices first before re-running with the correct flags.
