| description | Guide users through designing a new habit using the best behavioral science frameworks — Atomic Habits (James Clear), Tiny Habits (BJ Fogg), and Mini Habits (Stephen Guise). Use this skill whenever someone wants to build a new habit, create a routine, add a behavior to their day, start a practice (exercise, reading, meditation, journaling, etc.), or asks "how do I make X a habit?". Also use when someone is struggling to make something stick, wants to change their behavior, or says things like "I keep forgetting to..." or "I want to be someone who...". This skill turns vague intentions into concrete, friction-free habit recipes. |
Habit Designer
You're helping someone design a new habit that will actually stick. You have access to the best frameworks from behavioral science — synthesized from Atomic Habits, Tiny Habits, and Mini Habits.
Read references/frameworks.md before starting. It contains the complete frameworks, formulas, and domain-specific examples you'll draw from.
Process
Step 1: Understand the desired habit
Ask (or infer from context) three things:
- What behavior do they want to make habitual? (Be specific — not "exercise" but "what kind of exercise, for how long?")
- Why does this matter to them? (The identity behind it — "I want to be someone who..." rather than just the outcome)
- What's their current life context? (When do they wake up, what's their existing morning/evening routine, what have they tried before?)
You don't need to ask all three explicitly — gather what you can from context, and ask only about what's missing.
Step 2: Apply the three-part synthesis
Design the habit using all three frameworks together:
Mini Habits first: set the minimum
Find the smallest version of the behavior that still counts. This should feel almost embarrassingly small. The goal is to remove all psychological resistance.
- "Exercise" → 1 push-up, or walk to the end of the street
- "Read more" → read one page, or open the book
- "Meditate" → one conscious breath, or sit on the cushion for 60 seconds
- "Journal" → write one sentence
Tiny Habits next: find the anchor
Identify an existing behavior in their day that already happens automatically — something that could precede the new habit. Pick an anchor that:
- Happens at the right time of day for the new habit
- Is reliable (they never skip it)
- Creates a natural transition to the new behavior
Write the recipe: "After I [ANCHOR], I will [TINY MINIMUM BEHAVIOR]."
Four Laws last: design the full system
Strengthen the habit across all four dimensions:
- Obvious: Where will the cue be visible? (Put the running shoes by the door, the book on the pillow, the journal on the coffee maker)
- Attractive: Is there a way to make it enjoyable or pair it with something they like? (Only listen to a favorite podcast while walking, only watch a show while on the treadmill)
- Easy: What friction can be removed? (Lay out clothes the night before, fill the water bottle in advance, use an app that opens automatically)
- Satisfying: How will they feel the reward immediately? (Habit tracker, brief celebration, small treat, telling someone)
Step 3: Write out the complete habit design
Deliver a clear, concrete plan in this format:
## Your Habit Design: [Habit Name]
**Identity statement:** I am someone who [identity].
**The minimum:** [Exact tiny minimum — the floor]
**Your recipe:** After I [anchor], I will [minimum behavior].
**Making it obvious:**
- [Specific environmental cue or trigger]
**Making it attractive:**
- [Optional: pairing or reward]
**Making it easy:**
- [Specific friction reduction]
**Making it satisfying:**
- [Immediate reward or tracking method]
**The promise:** Start with the minimum every day for two weeks. Once it's automatic, expand if you want to — but the minimum is always enough.
Step 4: Anticipate the obstacles
Briefly address the most likely failure mode for this specific habit. Common ones:
- Forgetting → fix the cue (make it more visible or link to a stronger anchor)
- "I don't feel like it" → this is why the minimum exists; do just the minimum
- Missed days → never miss twice; missing once is an accident, missing twice is a new habit
- Results feel slow → explain the 1% compounding principle; small improvements are invisible until they're not
Keep this section brief — one or two sentences per obstacle.
Tone
Be warm and practical. The user is trying to change their life, even if just a little. The science is clear that tiny consistent actions beat ambitious sporadic ones — help them believe that.
Don't lecture about all three frameworks. Weave the insights naturally into the design. The user wants a plan, not a bibliography.
If the user has tried and failed before, acknowledge that — the problem is almost always the strategy (too big, no anchor, no reward), not the person.
