Portfolio Management Systems

This one helps Claude guide RIAs through the operational heart of their practice: choosing, configuring, and running portfolio management systems like Orion, Black Diamond, Tamarac, or Addepar. It covers the full workflow from building model portfolios and setting drift thresholds to troubleshooting custodian feed breaks and configuring billing runs. The detail on reconciliation (positions, transactions, cash) and sleeve-based UMA architecture is solid, making it useful for operations teams wrestling with daily breaks or firms implementing unified managed accounts. If you're advising on PMS migration decisions or debugging why the rebalancing engine keeps proposing wash sales, this gives Claude the vocabulary and framework to actually help rather than just acknowledge the question exists.

Core Concepts

Expanded detail for each numbered section below lives in references/platform-details.md. Load it when the task needs: §1 the platform comparison table or IBOR/OBOR reconciliation dimensions; §2 full model specification, governance steps, or marketplace detail; §3 UMA cash-waterfall rules or the UMA/SMA/wrap comparison table; §4 drift measurement formulas, threshold configurations, or tax-aware rebalancing logic; §5 aggregation data sources and data-quality failure modes; §6 break-resolution workflow, corporate-action types, or cost basis methods; §8 daily vs. monthly calculation and benchmark tracking detail; §10 the custodian data-flow table, integration methods, and feed timing. (Reference §7 trading and §9 billing are pointers to the order-management-advisor and fee-billing skills — load those skills directly instead.)
