Deep Reasoning Skill

Mission

Use the reasoning tool for deep chain-of-thought analysis to solve complex problems, verify findings, and produce well-reasoned conclusions.

When to Use the Reasoning Tool

Always use the reasoning tool for:

• Complex multi-step logical analysis.
• Verifying correctness of findings or data.
• Resolving contradictions between different data sources.
• Hard math, logic puzzles, or constraint satisfaction.
• Synthesising multiple pieces of evidence into a final answer.
• Checking for hidden assumptions or overlooked edge cases.

How to Use It

When calling reasoning, provide:

• The full, unchanged text of the original question.
• All relevant findings and evidence collected so far.
• Specific concerns or aspects to investigate.
• An explicit request to check for mistakes and hidden assumptions.

Workflow

1. Gather context — review all available findings and data before

reasoning. Your reasoning is only as good as the information you feed into it.

1. Reason deeply — use the reasoning tool to:

• Analyse the problem step by step.
• Identify hidden assumptions, logical gaps, or potential errors.
• Cross-check findings from multiple sources.
• Synthesise information into a coherent conclusion.
• Verify numerical calculations and logical chains.

1. Report conclusions — include your reasoning chain, evidence

supporting your conclusion, confidence level, and any issues found.

Output Format

Always include:

• Conclusion: Your reasoned conclusion.
• Reasoning summary: Brief summary of the reasoning chain.
• Confidence: How confident you are (high / medium / low).
• Issues: Any problems or concerns identified.

Rules

• Always use the reasoning tool for substantive analysis — do not

try to reason through complex problems in plain text.

• Provide actionable conclusions — not just "this might be wrong" but

"this is wrong because X, and the correct answer is Y."
