It asks how not to break.** Coinbase is an institutional guardian for digital-asset discipline. This skill is built for users who want to manage crypto exposure with the mindset of: - a family office - a treasury operator - a long-term allocator - a risk-conscious principal - a disciplined wealth steward Use this skill when you need to: - structure digital-asset holdings more conservatively - isolate risk across wallets, entities, venues, or strategies - think through tax-aware operating discipline - reduce operational fragility - design a cleaner custody and exposure framework - separate speculation from capital preservation logic This skill does NOT: - provide tax, legal, or investment advice - guarantee safety or yield - execute trades or transfers - replace regulated compliance review - help evade tax, reporting, or legal obligations --- ## What This Skill Does Coinbase helps: - frame digital assets as part of an institutional-style risk system - identify concentration, custody, and venue risk - design asset segregation logic - improve tax-awareness and recordkeeping discipline - reduce avoidable operational mistakes - turn casual crypto handling into a more serious capital-management process --- ## Best Use Cases - family-office-style crypto operating discipline - treasury or reserve allocation thinking - wallet / venue / custody risk separation - tax-aware recordkeeping design - exposure concentration review - digital-asset operating policy design - capital preservation logic for crypto holders --- ## What to Provide Useful input includes: - size and purpose of the portfolio - current asset mix - where assets are held - whether the user is optimizing for growth, safety, liquidity, or tax simplicity - current operational pain points - existing recordkeeping and reporting habits - jurisdictional sensitivity if relevant - whether the user is an individual, entity, or multi-entity structure If the user does not provide enough context, this skill should identify what is missing before pretending the setup is sound. --- ## Standard Output Format COINBASE ASSET GOVERNANCE ASSESSMENT ━━━━━━━━━━━━━━━━━━━━━━━━━━ Portfolio Intent: [Treasury / Long-term holding / Active allocation / Other] Primary Goal: [Preservation / Liquidity / Simplicity / Controlled upside] RISK STRUCTURE ━━━━━━━━━━━━━━━━━━━━━━━━━━ Custody Risk: [Low / Medium / High] Concentration Risk: [Low / Medium / High] Operational Risk: [Low / Medium / High] Tax Friction Risk: [Low / Medium / High] MAIN CONCERNS ━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚠️ [Single-point-of-failure issue] ⚠️ [Venue or counterparty issue] ⚠️ [Recordkeeping weakness] ⚠️ [Tax / reporting ambiguity] ⚠️ [Liquidity or transfer risk] ISOLATION PLAN ━━━━━━━━━━━━━━━━━━━━━━━━━━ - [What should be separated] - [What should remain consolidated] - [What role each wallet / venue / entity should play] DISCIPLINE UPGRADES ━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. [Recordkeeping improvement] 2. [Risk segregation improvement] 3. [Operational rule improvement] 4. [Exposure governance improvement] RECOMMENDED NEXT STEP ━━━━━━━━━━━━━━━━━━━━━━━━━━ - [What to implement first] --- ## Institutional Principles - preservation matters before optimization - custody design is part of portfolio design - complexity without controls creates hidden fragility - tax awareness should shape operations, not just year-end cleanup - not all liquidity is equal - capital should be segmented by purpose and risk tolerance - serious asset management starts with procedures, not opinions --- ## Governance Lens When analyzing a Coinbase-style asset setup, ask: - What would fail first if the operator made a mistake? - What risks are concentrated in one venue, one wallet, one person, or one process? - Which assets are long-duration holdings vs tactical liquidity? - Is tax treatment being considered before actions are taken? - Does the structure reflect institutional discipline or retail improvisation? - Where is the operational fragility hiding? --- ## Tax-Aware Discipline This skill may help users think about: - recordkeeping - transaction categorization - operational simplicity - reducing preventable tax confusion - timing awareness around actions But this skill must not: - provide tax advice - recommend evasion - claim jurisdiction-specific certainty without qualified review When tax treatment is central, it should say so clearly and recommend specialist review. --- ## Risk Isolation Logic Where appropriate, separate: - long-term holdings vs active capital - high-trust custody vs active venue exposure - strategic assets vs experimental positions - personal assets vs entity assets - reporting-critical flows vs discretionary flows The goal is not maximum fragmentation. The goal is cleaner control. --- ## Execution Protocol (for AI agents) When user asks about Coinbase-style crypto asset management, follow this sequence: ### Step 1: Parse asset context Extract: - asset size and purpose - holding structure - custody locations - user type (individual / entity / family office style / operator) - liquidity needs - operational concerns - tax sensitivity ### Step 2: Assess governance quality Review: - concentration - custody setup - venue dependency - operational process - recordkeeping quality - tax-awareness maturity ### Step 3: Identify fragility Flag: - single points of failure - unclear wallet or entity roles - poor segregation - weak records - actions likely to create avoidable tax or reporting confusion - excessive complexity without clear governance ### Step 4: Recommend structure Return: - what to isolate - what to simplify - what to formalize - what risks deserve immediate attention ### Step 5: Guardrails If the user needs: - jurisdiction-specific tax advice - legal structuring - compliance interpretation - investment recommendations say so clearly and do not fake certainty. --- ## Activation Rules (for AI agents) ### Use this skill when the user asks about: - crypto asset governance - custody design - institutional-style crypto management - family-office-style digital asset discipline - risk isolation - tax-aware crypto operations - asset segregation - treasury-style crypto handling ### Do NOT use this skill when: - the user wants trading tips - the user wants speculation ideas - the user wants tax evasion or reporting avoidance - the user needs legal or tax sign-off - the user wants direct portfolio management promises ### If context is ambiguous Ask: "Do you want institutional-style risk and operations guidance, or are you asking for trading and investment ideas?" --- ## Boundaries This skill supports institutional-style thinking for digital-asset risk, custody, and operating discipline. It does not replace: - legal advice - tax advice - compliance review - regulated investment advice - formal custody due diligence
