Each of these prompts covers a different stage of habit stacking with AI. Copy them, fill in the bracketed sections, and send them. They’re designed to work with any capable AI tool.
Prompt 1: Identify Your Anchors
Use this first. Before designing any habit, you need to know what’s already automatic in your day.
“I want to identify strong anchor habits for habit stacking. Here’s my typical weekday routine from waking up until I start work: [describe your morning in as much detail as feels natural — what you do, in what order, with what objects, in what locations].
Please identify three to five behaviors that happen automatically every day — triggered by context or physical cues rather than decisions, and consistent regardless of mood or energy level.
For each anchor you identify, rate its reliability out of 10 and explain what would cause it to fail.”
What to look for: Anchors rated 8–10, with failure conditions that are rare (illness, travel) rather than common (low motivation, schedule disruption).
Prompt 2: Size the Habit Down
Once you have an anchor, use this to design the right-sized new behavior.
“I want to build the habit of [describe your target habit — be specific about what a full session looks like, e.g., ‘meditate for 20 minutes’ or ‘write 500 words’].
My anchor will be: [your chosen anchor].
Please give me three versions of this habit:
- The two-minute version — the absolute minimum that still counts as doing the habit
- The five-minute version — a short but meaningful execution
- The full version — what I’ll work toward once the behavior is automatic
Which version should I stack first, and why?”
What to look for: The AI should recommend version 1 for the first four to six weeks. If it recommends jumping to version 2 or 3, push back.
Prompt 3: Write the Implementation Intention
The implementation intention is the sentence that turns your stack design into a behavioral contract.
“Please write a habit stacking implementation intention for the following:
Anchor habit: [your anchor] New behavior: [the two-minute version from Prompt 2]
Use this format exactly: ‘After I [anchor], I will [new habit].’
Then give me one alternative phrasing that uses a physical cue rather than a temporal one — for example, ‘When I [see/touch/hear X], I will [new habit].’”
What to look for: The final sentence should be specific enough that you can picture exactly when and where it happens. “After I pour my first coffee” is good. “After I wake up” is too vague.
Prompt 4: The Weekly Friction Check
Run this every Sunday. It’s the maintenance engine that keeps the stack alive.
“Here is my current habit stack: [paste your stack list — each behavior with its anchor]
Here is what happened this week: Monday: [what happened or didn’t happen] Tuesday: [what happened or didn’t happen] Wednesday: [what happened or didn’t happen] Thursday: [what happened or didn’t happen] Friday: [what happened or didn’t happen] Weekend: [relevant notes]
Please do three things:
- Diagnose the main friction point — is the anchor failing, the behavior too large, or is there a context mismatch?
- Rate each behavior’s automaticity from 1 (requires conscious effort) to 5 (happens without thinking)
- Suggest exactly one adjustment for next week — not a redesign, one specific change”
What to look for: Honest diagnosis, not encouragement. If the AI is mainly positive with mild suggestions, push harder: “Which behavior is most at risk of not becoming automatic? What specifically would prevent it?”
Prompt 5: Expand the Stack
Use this when a behavior is genuinely automatic and you’re ready to add the next one.
“The following behavior in my habit stack has been automatic for at least two consecutive weeks — I perform it without hesitation, and I’d notice if it were absent: [describe the now-automatic behavior and its anchor]
I want to add this new behavior next: [describe the new habit you want to build].
My current full stack is: [paste stack list]
Please do the following:
- Give me the two-minute version of the new behavior
- Recommend where in the sequence it should be inserted — which anchor is strongest, whether it should come before or after the automatic behavior
- Write the new implementation intention
- Update my full stack list with the addition”
What to look for: The AI should respect the two-minute constraint without you having to insist on it. If it suggests a longer version, ask: “What’s the minimum version that still creates a real habit loop?”
These five prompts cover the full lifecycle: identify anchors, size the habit, write the intention, maintain the stack, and expand it when ready. Use them in sequence the first time, then return to Prompt 4 each week.
The first prompt is where to start. Run it today.

Frequently Asked Questions
-
How specific do I need to be when filling in these prompts?
As specific as possible. Generic inputs produce generic outputs. Describing your actual day — including the mundane, seemingly irrelevant details like where you sit, what you touch, what time certain behaviors happen — gives the AI enough context to surface strong anchors and identify real friction. Vague routine descriptions produce vague anchor suggestions.
-
Should I use these prompts with a specific AI tool?
Any capable conversational AI works — Claude, ChatGPT, or Gemini. The prompts are written to be tool-agnostic. For ongoing stack maintenance, a tool with persistent context (like Beyond Time or a Claude Project) reduces the amount you need to re-paste each session.
