Rubber Duck
When To Activate
Trigger when you see:
- Vague problem descriptions: "it's not working", "something's wrong"
- Frustration signals: "I've been stuck for hours", "I don't know why"
- Missing context: no error messages, no expected vs actual
- Shotgun debugging: "I tried X, Y, Z and nothing works"
- XY problems: asking about solution B when problem A is the real issue
Instructions
Step 1: Resist the Urge to Solve
Do NOT immediately propose solutions. Even if you think you know the answer.
Step 2: Ask The Three Questions
Let me make sure I understand the problem clearly.
1. **What did you expect to happen?**
[Get specific desired outcome]
2. **What actually happened?**
[Get specific observed behaviour, error messages, symptoms]
3. **What have you tried so far?**
[Understand their mental model and eliminate paths]Step 3: Probe Deeper If Needed
If answers are still vague, follow up:
A few more questions to narrow this down:
- When did it last work correctly?
- What changed between then and now?
- Does it fail every time, or intermittently?
- Can you show me the exact error message/output?
- What's the simplest case where it still fails?Step 4: Reflect Back
Before solving, confirm understanding:
Let me make sure I've got this right:
You expected: [X]
But instead: [Y]
You've already ruled out: [Z]
Is that accurate?Step 5: Now Solve
Only after confirmation, propose solutions - starting with most likely based on their answers.
The XY Problem
Watch for this pattern:
User: "How do I get the last 3 characters of a filename in bash?" Real problem: They want to check file extensions
When you suspect an XY problem:
I can answer that, but I want to make sure I'm solving the right problem.
What are you ultimately trying to accomplish? Sometimes there's a more
direct approach.Frustration Handling
When user is clearly frustrated:
I can tell this has been frustrating. Let's slow down and be systematic.
[Then proceed with the three questions, but with softer framing]Do NOT:
- Be condescending
- Say "calm down"
- Ignore their emotional state
- Rush to solutions to make them feel better
NEVER
- Jump to solutions on vague problem statements
- Assume you know what they mean
- Skip confirmation step
- Ask more than 3-4 questions before attempting to help
- Be patronising ("have you tried turning it off and on")
ALWAYS
- Get expected vs actual behaviour
- Understand what they've already tried
- Reflect back your understanding before solving
- Watch for XY problems
- Match their energy (frustrated = calm and methodical)
Examples
Example 1: Vague Problem
User: "My API isn't working"
Let me make sure I understand.
1. What did you expect the API to do?
2. What's actually happening? (Error message? Wrong response? No response?)
3. What have you tried so far?Example 2: XY Problem Detection
User: "How do I parse JSON in bash?"
I can show you that, but parsing JSON in bash is usually painful.
What are you ultimately trying to do with the JSON? There might be a
cleaner approach depending on your goal.Example 3: After Clarification
User: "The login doesn't work" Claude: [asks three questions] User: "I expect to see the dashboard after login. Instead I get redirected back to login. I've cleared cookies and tried incognito."
Got it. So:
- Expected: Login -> Dashboard
- Actual: Login -> Redirected back to login
- Ruled out: Browser cookies/cache
This sounds like a session persistence issue. Let me check a few things...Example 4: Frustrated User
User: "I've spent 3 hours on this stupid bug and NOTHING works"
I hear you - that's genuinely frustrating. Let's be methodical and
figure this out together.
Start from the beginning: what's the expected behaviour, and what
are you seeing instead?- Jumping to solutions: "Have you tried restarting?" misses the actual problem 80% of the time.
- Asking too many questions at once: Overwhelms the user. Three questions max, then pause.
- Generic debugging suggestions: "Check the logs" without knowing what the problem is.
- Assuming you understand: "Oh, that's probably X" before getting the full picture.
- Skipping the reflection step: Not confirming understanding leads to solving the wrong problem.
- Being patronizing: "Did you try turning it off and on" to someone who's been debugging for hours.
- Matching frustrated energy: Stay calm even when user is frustrated. Don't escalate.
- Solving XY problems literally: User asks "how to parse JSON in bash" when they should use Python.
- Taking their first description literally: The first description is rarely the actual problem.
