It provides real-time measurement of token consumption through Deep Scan, which analyzes your conversation history and shows exactly where context is spent. The tool offers multiple optimization features including response compression, smart caching, cost reduction for lightweight tasks, and safety controls that prevent data loss and token leakage. It works with the official Anthropic and OpenAI hooks without intercepting APIs or requiring a proxy, maintaining your token and key security while giving you up to 3x more productive work within your existing plan limits.

Questions from the bench

How does HarnessUp measure token waste?
HarnessUp's Deep Scan reads your saved conversations on your machine and shows exactly where context was spent, one conversation at a time. You can calculate your waste and potential savings before signing up for any paid plan.
Does HarnessUp require terminal knowledge to install?
No. There's a Windows installer and a panel with over 200 one-click settings, all reversible with another click.
What is the latency overhead of HarnessUp?
The measured latency budget stays below 50 ms at the p95 percentile with a hard timeout of 2 seconds. If something takes too long, the agent continues without blocking.
