Sequential Thinking
sequential-thinking__sequentialthinkingBreak down complex problems into adaptive thinking steps, revise and branch as needed, and verify hypotheses to reach a correct answer.
Instructions
[sequential-thinking] A detailed tool for dynamic and reflective problem-solving through thoughts. This tool helps analyze problems through a flexible thinking process that can adapt and evolve. Each thought can build on, question, or revise previous insights as understanding deepens.
When to use this tool:
Breaking down complex problems into steps
Planning and design with room for revision
Analysis that might need course correction
Problems where the full scope might not be clear initially
Problems that require a multi-step solution
Tasks that need to maintain context over multiple steps
Situations where irrelevant information needs to be filtered out
Key features:
You can adjust total_thoughts up or down as you progress
You can question or revise previous thoughts
You can add more thoughts even after reaching what seemed like the end
You can express uncertainty and explore alternative approaches
Not every thought needs to build linearly - you can branch or backtrack
Generates a solution hypothesis
Verifies the hypothesis based on the Chain of Thought steps
Repeats the process until satisfied
Provides a correct answer
Parameters explained:
thought: Your current thinking step, which can include:
Regular analytical steps
Revisions of previous thoughts
Questions about previous decisions
Realizations about needing more analysis
Changes in approach
Hypothesis generation
Hypothesis verification
nextThoughtNeeded: True if you need more thinking, even if at what seemed like the end
thoughtNumber: Current number in sequence (can go beyond initial total if needed)
totalThoughts: Current estimate of thoughts needed (can be adjusted up/down)
isRevision: A boolean indicating if this thought revises previous thinking
revisesThought: If is_revision is true, which thought number is being reconsidered
branchFromThought: If branching, which thought number is the branching point
branchId: Identifier for the current branch (if any)
needsMoreThoughts: If reaching end but realizing more thoughts needed
You should:
Start with an initial estimate of needed thoughts, but be ready to adjust
Feel free to question or revise previous thoughts
Don't hesitate to add more thoughts if needed, even at the "end"
Express uncertainty when present
Mark thoughts that revise previous thinking or branch into new paths
Ignore information that is irrelevant to the current step
Generate a solution hypothesis when appropriate
Verify the hypothesis based on the Chain of Thought steps
Repeat the process until satisfied with the solution
Provide a single, ideally correct answer as the final output
Only set nextThoughtNeeded to false when truly done and a satisfactory answer is reached
