1. Step-by-Step Essay Architect
WRITINGBuild a deeply reasoned essay by breaking the topic down into logical steps.
Write a persuasive essay on [topic]. Before writing, outline the core argument in 3 logical premises. Then, for each paragraph, explicitly state the reasoning step you are making and provide evidence. End with a conclusion that follows directly from those steps. (Enable Thinking mode so the premise-outlining step is worked through deliberately before drafting begins.)

2. Chain-of-Thought Story Plotting
WRITINGDevelop a complex narrative with cause-and-effect reasoning.
I have a story idea: [brief premise]. Use chain-of-thought reasoning to develop a plot outline. Start with the inciting incident, then trace the logical consequences of each major character's decision. Identify where the story's internal logic could break and suggest fixes. (Run this with Thinking mode on - the "where could this break" check is exactly what that mode is built for.)

3. Precision Editing for Technical Documents
WRITINGFast, sharp attention to detail for tightening technical prose - no heavy deliberation needed.
Edit this technical document for clarity and precision: [paste document]. Focus on: ambiguous terms, redundant phrases, and any logical leaps. For each change, briefly explain why it improves the argument. Preserve all factual content. (This is a good fit for Non-Thinking mode - it's a direct editing pass, not a problem needing extended deliberation.)

4. Multi-Perspective Dialogue Builder
WRITINGCreate dialogue that reflects distinct worldviews and reasoning styles.
Write a dialogue between [character A] and [character B] on [conflict]. Each character should argue from a coherent, internally consistent worldview. After the dialogue, provide a brief analysis of the logical strengths and weaknesses of each position. (Thinking mode helps here since checking each position for internal consistency is itself a reasoning task, not just a writing one.)

5. Long-Form Content with Signposting
WRITINGA long guide that keeps its own structure straight across the entire piece, not just the last section.
Write a comprehensive guide on [topic] (~2000 words, or longer if the topic genuinely needs it - this model's 1M-token context window means length isn't the constraint, clarity is). Use clear numbered signposts: "First, I will explain... Now we turn to...". After each major section, briefly summarize the key takeaway. Include a final "roadmap" summary at the end that's actually consistent with what was covered in the sections above it.

6. Logical Flow Check for Arguments
WRITINGTest whether your argument actually holds together, claim by claim.
Here is my draft argument: [paste text]. Check the logical flow. Does each claim follow from the previous one? Identify any non-sequiturs or unsupported leaps. Suggest where I need to add bridging reasoning or evidence. (Enable Thinking mode for this - working through each claim's support deliberately catches more gaps than a fast read-through.)

7. Abstract to Concrete Translator
WRITINGTurn dense philosophical or theoretical writing into accessible prose.
Translate this abstract passage into clear, concrete language for a general audience: [paste text]. Maintain all core ideas but replace jargon with everyday analogies. Then, explain how you simplified each key concept.

8. Mathematical Problem Solver with Reasoning
ANALYSISA full step-by-step derivation, DeepSeek's classic strength, now under the Thinking-mode toggle.
Solve this math problem: [problem statement]. Show every step of your reasoning. Explain why you chose each method, and after the solution, reflect on whether there is a simpler or alternative approach. Enable Thinking mode - this is precisely the class of problem it's built for, and it's worth checking the final answer against the alternate approach it suggests.

9. Root Cause Analysis with Fault Tree
ANALYSISApply systematic logical reasoning to complex problems, branch by branch.
I'm facing this problem: [describe problem]. Construct a fault tree analysis. Start with the top-level failure, then branch out possible direct causes. Keep drilling down until you reach root causes. Assign a tentative probability to each branch and recommend the most high-leverage fix. (Thinking mode is worth the extra latency here - a shallow first pass tends to miss the second- and third-level causes that matter most.)

10. Algorithmic Trading Logic Audit
ANALYSISDeepSeek's code and logic strength can review trading strategies.
Here is the logic for my trading algorithm: [describe logic/pseudocode]. Audit it for hidden assumptions, look-ahead bias, and unrealistic fills. Simulate a mental backtest under high volatility and explain where the strategy might break. Suggest protective logic.

11. Argument Deconstruction & Steelmanning
ANALYSISDeepSeek can strip an argument to its logical skeleton and rebuild it stronger.
Deconstruct this argument: [paste argument]. Extract the premises and the conclusion. Test if the conclusion follows. Then, steelman the opposing view build the strongest possible counter-argument using the same factual base. End with an evaluation of which side has the stronger logic.

12. Statistical Fallacy Checker
ANALYSISDeepSeek can spot subtle misuse of statistics.
Here is a claim with supporting stats: [paste text]. Examine the statistical reasoning. Check for base rate neglect, cherry-picked timeframes, Simpson's paradox traps, and causation vs. correlation errors. Explain any flaws in plain language.

13. Business Model Viability Stress Test
ANALYSISUse DeepSeek's reasoning to pressure-test a business model.
Stress test this business model: [describe model]. Analyze unit economics, customer acquisition cost assumptions, and churn rates. Then simulate three scenarios: rapid growth, recession, and a strong competitor entering. Highlight the weakest assumptions.
