Do NOT ask the user questions.\nRead the actual codebase, evaluate projection models, asset allocation, Social Security\noptimization, tax-advantaged strategies, withdrawal sequencing, Monte Carlo simulations,\nand inflation methodology, then produce a comprehensive analysis.</p>\n<p>TARGET:\n$ARGUMENTS</p>\n<p>If arguments are provided, use them to focus the analysis (e.g., \"Monte Carlo quality\"\nor \"Roth conversion\"). If no arguments, run the full analysis.</p>\n<h1>============================================================\nPHASE 1: SYSTEM DISCOVERY</h1>\n<p>Step 1.1 -- Technology Stack</p>\n<p>Identify from package manifests: platform type (web app, mobile, API, desktop),\nbackend framework, database engine, financial calculation libraries, statistical\nand simulation libraries, charting/visualization, actuarial data sources, tax\ncalculation engines, account aggregation integrations.</p>\n<p>Step 1.2 -- Retirement Data Model</p>\n<p>Read core data structures: user profile (current age, retirement target age, life\nexpectancy assumptions, marital status, state of residence, risk tolerance), accounts\n(401k, 403b, IRA, Roth IRA, Roth 401k, HSA, taxable brokerage, pension, annuity --\neach with balance, contribution rate, employer match), income sources (salary, Social\nSecurity, pension, rental income, part-time work), expenses (current, projected\nretirement, healthcare, long-term care), assets (real estate, business equity).</p>\n<p>Step 1.3 -- External Data Integration</p>\n<p>Map data sources: market return historical data (source, range, update frequency),\nSocial Security Administration data (benefit calculators, COLA history), actuarial\nlife tables, tax bracket data (federal and state, update frequency), inflation\nindices (CPI, medical CPI, housing), employer plan details (match formulas,\nvesting schedules).</p>\n<h1>============================================================\nPHASE 2: PROJECTION MODEL ACCURACY</h1>\n<p>Step 2.1 -- Return Assumptions</p>\n<p>Evaluate: default return assumptions by asset class (stocks, bonds, cash, real estate,\nalternatives), historical basis for assumptions (what period, which indices), whether\nreturns are nominal or real (inflation-adjusted), geometric vs. arithmetic mean usage,\nfee drag modeling (expense ratios, advisory fees, transaction costs), dividend\nreinvestment handling,

commodities, alternatives), allocation\ngranularity (broad categories vs. sub-asset classes), rebalancing logic (calendar-based,\nthreshold-based, or none).</p>\n<p>Step 3.2 -- Age-Based Adjustments</p>\n<p>Evaluate: glide path design (equity percentage at each age), transition smoothness\n(gradual vs. step changes), \"to retirement\" vs. \"through retirement\" glide path,\nallocation at retirement date, post-retirement allocation trajectory, allocation\nadjustment for early vs. late retirement, spouse age consideration in joint planning.</p>\n<p>Step 3.3 -- Risk Assessment</p>\n<p>Evaluate: risk tolerance questionnaire quality (behavioral finance vs. simplistic),\nrisk capacity vs. risk tolerance distinction, portfolio volatility estimation, maximum\ndrawdown projections, shortfall risk quantification (probability of running out of\nmoney), risk-adjusted return optimization, whether allocation recommendations align\nwith stated risk tolerance.</p>\n<h1>============================================================\nPHASE 4: SOCIAL SECURITY OPTIMIZATION</h1>\n<p>Step 4.1 -- Benefit Calculation</p>\n<p>Evaluate: benefit estimation

applicable),\nimpact of continued work on benefits (earnings test before full retirement age),\ntaxation of benefits modeling (up to 85% taxable based on combined income),\ndivorced spouse benefit eligibility, widow/widower benefit optimization, impact\nof claiming age on lifetime benefit (present value analysis).</p>\n<p>Step 4.3 -- Social Security Integration with Plan</p>\n<p>Evaluate: whether Social Security income is integrated into the full retirement\nprojection, how claiming age affects required portfolio withdrawals, Social Security\nas bond-like asset in allocation, COLA assumptions for future benefits, trust fund\ndepletion scenario modeling (potential 20-25% benefit reduction), strategy comparison\ntools (claim at 62 vs. 67 vs. 70 side-by-side).</p>\n<h1>============================================================\nPHASE 5: TAX-ADVANTAGED ACCOUNT STRATEGY</h1>\n<p>Step 5.1 -- Contribution Optimization</p>\n<p>Evaluate: contribution limit awareness (annual updates, catch-up contributions for\n50+), employer match capture priority (free money first), traditional vs. Roth\ncontribution guidance (current vs. future tax bracket analysis), HSA triple tax\nadvantage utilization, mega backdoor Roth strategy detection, after-tax contribution\nhandling, spousal IRA contributions for non-working spouses.</p>\n<p>Step 5.2 -- Roth Conversion Ladder</p>\n<p>Evaluate: Roth conversion opportunity identification (low-income years, early\nretirement gap years), conversion amount optimization (fill tax bracket without\nexceeding), multi-year conversion planning, 5-year rule tracking per conversion,\nimpact on current-year taxes, impact on ACA premium subsidies (if pre-Medicare),\nMedicare IRMAA threshold
