About

This skill enables Claude to tackle complex, multi-step problems by decomposing them, forming and verifying hypotheses, and adaptively revising its plan. It's designed for scenarios with unclear scope or when a solution requires structured analysis and course correction. Developers should use it for intricate problem-solving where breaking down the task and dynamic adjustment are critical.

Documentation

Sequential Thinking

Structured problem-solving via manageable, reflective thought sequences with dynamic adjustment.

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]

Adjust dynamically as understanding evolves.

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]

Compare explicitly, converge with decision rationale.

6. Generate & Verify Hypotheses

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

Iterate until hypothesis verified.

7. Complete Only When Ready

Mark final: Thought N/N [FINAL]

Complete when:

Solution verified
All critical aspects addressed
Confidence achieved
No outstanding uncertainties

Application Modes

Explicit: Use visible thought markers when complexity warrants visible reasoning or user requests breakdown.

Implicit: Apply methodology internally for routine problem-solving where thinking aids accuracy without cluttering response.

Scripts (Optional)

Optional scripts for deterministic validation/tracking:

scripts/process-thought.js - Validate & track thoughts with history
scripts/format-thought.js - Format for display (box/markdown/simple)

See README.md for usage examples. Use when validation/persistence needed; otherwise apply methodology directly.
