I measured every token of it, deleted it, and published all 267 raw runs — including the ones where I lose. /eco : −35% to −57% output tokens on the same review task across Opus 5, Sonnet 5, Opus 4.8 and Fable 5 (n=5 per arm, measured the same day), up to −73% on long agentic tasks at high effort — with both planted bugs found in every single run. Haiku is the documented exception. /eco-max : up to −75% by dialing reasoning effort down — opt-in, labeled. Since 1.2.0 the same rules also ship as an output style (zero invocation cost), plus opt-in hooks that enforce the expensive rules mechanically instead of asking the model nicely.

The waste it removes isn't occasional — it repeats on every turn of every session , which is why usage limits evaporate and API bills surprise you. What you get Component What it does Cost when idle --- --- --- /eco Frugality rules with a non-negotiable quality floor. Full reasoning depth. One invocation covers the session. 80 tok /eco-max The same rules plus a low reasoning-effort override for routine chores.
