Token-Warden: AI habits that actually save money

Meet the office manager your AI assistants never knew they needed. Token-Warden quietly tracks every token your AI spends, flags when a task costs more than usual, and tests proposed habits on a frozen set of practice tasks. Only rules that save at least twice what they cost stay in memory; the rest are evicted without ceremony.
A receipt for every thought
Every AI task leaves a paper trail: the tokens used, the files opened, the detours taken. Token-Warden saves this receipt in a drawer labeled “cost ledger.” When a task blows the budget, it asks a junior AI to explain why—and to suggest a habit that might cut the bill, like searching for the right file before opening random ones.
The habit audit
Instead of accepting hunches, Token-Warden runs a controlled experiment. It executes the same practice tasks twice—once with the new habit, once without—and records the difference in token use. A habit must deliver at least twice the savings it consumes in memory space, or it’s shown the door. Winners are written into the agent’s permanent memory; losers are remembered only as failed experiments.
Self-funding memory
Agent memory is often cluttered with unverified advice. Token-Warden treats context space as a scarce resource: every rule must earn its keep by lowering token costs on a fixed benchmark. Active rules are re-tested in rotation, and those that stop paying rent are removed automatically. Collection happens in a background hook that never blocks your work, so the system pays for itself without interrupting the flow.
