Token Kits
One battle-tested pack that cuts agent token costs roughly in half. Installed from GitHub into the file your IDE reads.
Promise
Cut token costs in half with one line of code — always-on rules, not a chat tip you re-paste every session.
What it enforces
- Tiny context packs — budgets by task size (bug fix vs feature vs refactor)
- Hard stops — no folder dumps, no full log history, no stacked “extras”
- Dense replies — plan → edits → verify
- Cost flags — green / yellow / red self-check before expanding context
Pricing
- Prelaunch — $39 one-time for the first 100 users
- Regular — $79 one-time after prelaunch

Who it’s for
Developers and teams paying real money for Cursor, Claude Code, Windsurf, Copilot, or similar agents — and watching context spend climb because soft prompts don’t stick.
