From grimoire
Attaches a new habit to an existing anchor habit (e.g., morning coffee) using an explicit formula, with a 2-minute starter and tracking to build consistency.

Attach a new habit to an existing anchor habit so that the current behavior becomes the automatic cue.
Attach a new habit to an existing anchor habit so that the current behavior becomes the automatic cue.
Adopted by: Behavior design programs at Stanford (BJ Fogg's Tiny Habits), corporate wellness programs, athletic training systems Impact: Gollwitzer (1999): implementation intentions — specifying exact when/where/how — double habit adoption success rates vs. intention alone; Clear: habit stacking creates unambiguous cues that eliminate the decision of when to start
Why best: The brain encodes behavior as sequences. Attaching a new behavior to an established one borrows the existing neural pathway as a trigger, removing the need for willpower or memory. Starting at 2 minutes eliminates the resistance barrier that causes most new habits to collapse in week two.
Formula: "After I pour my morning coffee, I will open my journal and write one sentence."
Expansion path: Week 1–2: one sentence → Week 3–4: five sentences → Month 2: ten-minute freewrite
Bad anchor: "After I feel motivated" — motivation is not a reliable cue; use a concrete, timed behavior
npx claudepluginhub jeffreytse/grimoire --plugin grimoireAnchors new habits to existing daily routines using habit stacking technique from Clear, Fogg, and Duhigg. Use when building a new behavior cue.
Creates if-then implementation intentions and WOOP plans for student behaviour change goals. Use when students know what to do but struggle to follow through on habits or routines.
Diagnoses why a behavior persists and designs interventions using habit loops, friction analysis, and the intention-behavior gap.
