Sequential Thinking

When to Apply

• Complex problem decomposition
• Adaptive planning with revision capability
• Analysis needing course correction
• Problems with unclear/emerging scope
• Multi-step solutions requiring context maintenance
• Hypothesis-driven investigation/debugging

Core Process

1. Start with Loose Estimate

Thought 1/5: [Initial analysis]

2. Structure Each Thought

• Build on previous context explicitly
• Address one aspect per thought
• State assumptions, uncertainties, realizations
• Signal what next thought should address

3. Apply Dynamic Adjustment

• Expand: More complexity discovered → increase total
• Contract: Simpler than expected → decrease total
• Revise: New insight invalidates previous → mark revision
• Branch: Multiple approaches → explore alternatives

4. Use Revision When Needed

Thought 5/8 [REVISION of Thought 2]: [Corrected understanding]
- Original: [What was stated]
- Why revised: [New insight]
- Impact: [What changes]

5. Branch for Alternatives

Thought 4/7 [BRANCH A from Thought 2]: [Approach A]
Thought 4/7 [BRANCH B from Thought 2]: [Approach B]

6. Generate & Verify Hypotheses

Thought 6/9 [HYPOTHESIS]: [Proposed solution]
Thought 7/9 [VERIFICATION]: [Test results]

7. Complete Only When Ready

Thought N/N [FINAL]

• Solution verified
• All critical aspects addressed
• Confidence achieved
• No outstanding uncertainties
