xhigh Reasoning — Frontier Maths Problem
effort: xhighreasoning_effort: xhigh Solve the following problem with full rigour, showing every step: A convex polytope P in ℝⁿ is defined by m linear inequalities. Prove that the number of vertices of P is at most C(m, n) — the binomial coefficient — and construct an explicit example of a polytope in ℝ³ defined by 6 inequalities that achieves the maximum vertex count C(6, 3) = 20 vertices. For the proof: 1. State and invoke the correct theorem about vertices as basic feasible solutions 2. Show why each vertex corresponds to a unique n-subset of the m constraints 3. Prove the upper bound rigorously, with no steps omitted For the construction: 1. Give explicit inequality coefficients 2. Enumerate all 20 vertices with their coordinates 3. Verify one vertex explicitly by solving the system

xhigh Reasoning — Strategic Due Diligence
effort: xhighreasoning_effort: xhigh I am considering acquiring a B2B SaaS company at a $40M valuation. Revenue: $3.2M ARR, growing 85% YoY. 120 customers, ACV $26,700. Net Revenue Retention: 118%. Gross margin: 71%. Team: 28 people (12 engineers). Primary risk: 2 customers account for 41% of ARR. Analyse this deal with maximum rigour: 1. VALUATION ASSESSMENT — is 12.5× ARR justified? Compare to sector comps 2. CONCENTRATION RISK — quantify the financial downside scenarios if the top 2 customers churn 3. RETENTION QUALITY — what does 118% NRR actually tell us, and what do we still need to know? 4. RED FLAGS — what would cause you to walk away? 5. VALUE CREATION PLAN — if you acquired it, the top 3 levers to get to $10M ARR in 24 months 6. NEGOTIATION POSITION — what terms and conditions would you insist on beyond price? Show all reasoning. Do not hedge every answer — take a position.

xhigh Reasoning — Complex Legal Analysis
effort: xhighreasoning_effort: xhigh Analyse the following legal scenario with the depth of a senior commercial litigator: Scenario: A SaaS company (Company A) has a signed contract with a customer (Company B) for a 3-year $1.2M deal. 14 months in, Company B is acquired by Company C. Company C immediately attempts to terminate the contract, claiming the change-of-control clause in their standard terms (which were never signed by Company A) allows them to exit without penalty. Company A's signed contract has a change-of-control clause that makes the contract assignable by the customer but does not allow termination on this basis. Analyse: 1. Which contract governs? Walk through the offer/acceptance/consideration analysis 2. Does Company C have grounds to terminate? Apply contract interpretation principles 3. What are Company A's remedies if Company C terminates anyway? 4. What is the litigation risk/reward analysis for Company A pursuing the remaining $635K? 5.

RUNBOOK: A 10-step runbook for the next person who sees this exact incident Think aloud. Do not wait for me to confirm each step — run through the full investigation assuming you have read-only access to production logs and metrics.
Visual Design System — Component Audit
effort: highI'm providing screenshots of 8 different pages from our SaaS application. Conduct a design system audit: 1. COMPONENT INVENTORY — list every UI component visible across all screens (buttons, inputs, cards, modals, navigation, etc.) 2. INCONSISTENCIES — where the same component appears with different visual treatment (colour, size, spacing, state) across screens 3.

Reasoning Effort: High — Technical Writing
effort: highreasoning_effort: high Write a technical deep-dive blog post (2,000 words) aimed at senior engineers explaining how large language model inference is optimised for speed at scale.

Grok 4.6 Prompt Tips
Do
- ✓ Use
reasoning_effort: xhighfor maths, law, strategy, algorithm design - ✓ Structure long-running agent tasks as numbered sequential phases
- ✓ Use the 500K context for full codebases, long RFPs, or large corpora
- ✓ Leverage image input for design audits, floor plans, and product photos
- ✓ Ask it to establish architecture before writing code — better first passes
- ✓ Use low/medium effort for classification and summarisation (saves cost)
Avoid
- ✗ Using xhigh for simple tasks — medium or high covers most work
- ✗ Asking for more than one complete visual build in a single prompt
- ✗ Confusing Grok 4.6 with Grok Imagine Image 2.0 (different capabilities)
- ✗ Vague agent prompts without named phases or deliverables
- ✗ Forgetting image input is available — describe both text + image context
- ✗ Neglecting to specify output format for structured data tasks
