- voice-baselinehuytieu/COG-second-brainMeasure your own writing corpus for the words and sentence shapes you over-use, so an agent writing in your voice stops amplifying your tics into a style.

Use when asked to build a habit, help me stick to [habit], I keep failing at [routine], or start a new habit. Produces a shrunk-down version of the habit, a concrete cue/anchor and time/place, a tracking method, a friction plan (make good easy, bad hard), and a get-back-on-track rule so one miss doesn't end it.DesignNo warnings★ 1.5K↓ —
