RTK — a token-optimized CLI proxy that wraps common dev commands and strips noise before it ever hits Claude. Across 1,360 commands, here's where the savings landed:

 #  Command                   Count   Saved    Avg%    Time
────────────────────────────────────────────────────────────
 1  rtk read                     51  549.1K   22.6%     0ms
 2  rtk:toml ps aux               4  252.7K   98.6%   166ms
 3  rtk:toml ps -ef               2   99.5K   98.7%   134ms
 4  rtk grep                    194   83.3K   35.5%     4ms
 5  rtk curl …nordvest…           1   20.0K   99.3%    47ms
 6  rtk find                     75   19.9K   68.9%     5ms
 7  rtk curl …                    1   14.7K   99.1%   335ms
 8  rtk curl …127…                2   12.7K   98.0%   112ms
 9  rtk curl …                    2   10.6K   97.6%   130ms
10  rtk git diff resources…       1   10.0K   85.2%    17ms

The big surprise: ps aux and ps -ef cost ~99% of their tokens in noise — a couple of process listings would have eaten 350K tokens uncompressed.

I know I'm the main power user of my own app Audio Brevity but this is kinda impressive...

I was super impressed with the airflow in my wife's hospital room (she's fine - routine stuff) as there were four people in the room and it stayed under 500 ppm. All through the hospital that day I didn't see it more than 500 ppm even in the crowded waiting room. Nice.

Working on a machine I didn't realize how fast I was in dangerous air. It's about knowing your air to make smart decisions.
