+It records a numbered thought, whether more thinking is needed, and optional revision or branch metadata.
+
+Use it when a task benefits from breaking work into steps, revising earlier assumptions, exploring alternatives, or extending the plan as new information appears.
+
+Guidance:
+- Start with an estimated totalThoughts count and adjust it as needed.
+- Set nextThoughtNeeded to true until the answer is ready.
+- Mark revisions with isRevision and revisesThought.
+- Mark branches with branchFromThought and branchId.
+- Use needsMoreThoughts when the current sequence should continue beyond the estimate.
+- Finish only when the reasoning is complete enough to produce the final answer.`;

     title: "Sequential Thinking",
-    description: `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:
-1. Start with an initial estimate of needed thoughts, but be ready to adjust
-2. Feel free to question or revise previous thoughts
-3. Don't hesitate to add more thoughts if needed, even at the "end"
-4. Express uncertainty when present
-5. Mark thoughts that revise previous thinking or branch into new paths
-6. Ignore information that is irrelevant to the current step
-7. Generate a solution hypothesis when appropriate
-8. Verify the hypothesis based on the Chain of Thought steps
-9. Repeat the process until satisfied with the solution
-10. Provide a single, ideally correct answer as the final output
-11. Only set nextThoughtNeeded to false when truly done and a satisfactory answer is reached`,
