92% of tokens saved — making the invisible cost of AI agents visible
RTK wraps common dev commands so only the essentials reach the agent's context window. A numbers breakdown across 13,361 commands and 114.8M tokens.
92% of tokens saved. 105.6M out of 114.8M.
That's what rtk gain reports — the RTK command that measures the toolkit's impact on my AI consumption.
The principle
Instead of dumping entire files or verbose outputs into an agent's context, RTK wraps common commands (find, grep, git diff, lint…) so they return only the essentials.
Some numbers across 13,361 commands
rtk find: 57.1% saved (82.6M total)rtk git diff --cached: 98.9%rtk lint eslint: 99.9% on linter output, often the most polluting
Making cost visible
What I like is that gain makes an ordinarily invisible cost visible. You code with an agent, you see the bill at the end of the month, but you have no idea where the tokens went.
Token-by-token frugality — that's also what AI engineering looks like in 2026.
What about you — which dev shortcuts save you the most?
