A scale for your AI's notes. Notes that pay their rent stay. Notes that don't get thrown out. And it refuses to claim a saving it can't prove.

Built with Claude Code, for Claude Code. Free and MIT - git clone and add it as a plugin, no signup, no paid tier. The problem: every rule in your agent's memory gets pasted into every session. That's rent you pay forever. Most people write rules and just assume they help - nothing checks. What it does: it runs a fixed set of coding tasks twice, once with the rule and once without, and compares actual token spend. A rule has to save at least double what it costs to carry. If it can't prove it, it gets deleted. github.com/vukkt/token-warden
