Serialization

Ensures alignment between user and Claude during feature/spec planning through a structured interview process. Use this skill when the user invokes /plan-interview before implementing a new feature, refactoring, or any non-trivial implementation task. The skill runs an upfront interview to gather requirements across technical constraints, scope boundaries, risk tolerance, and success criteria before any codebase exploration. Do NOT use this skill for: pure research/exploration tasks, simple bug fixes, or when the user just wants standard planning without the interview process.

Analyze code coverage and CRAP (Change Risk Anti-Patterns) scores to identify high-risk code. Use OpenCover format with ReportGenerator for Risk Hotspots showing cyclomatic complexity and untested code paths.

Implement, review, or improve maps and location features in iOS/macOS apps using MapKit and CoreLocation. Use when working with Map views, annotations, markers, polylines, user location tracking, geocoding, reverse geocoding, search/autocomplete, directions and routes, geofencing, region monitoring, CLLocationUpdate async streams, or location authorization flows. Also use when working with maps, coordinates, addresses, places, directions, distance calculations, or location-based features in Swift apps.

Guide the design, evaluation, and monitoring of trade execution quality and best execution practices. Use when assessing best execution obligations under FINRA Rule 5310 or RIA fiduciary duty, designing smart order routing across exchanges and dark pools, selecting execution algorithms (VWAP, TWAP, implementation shortfall, POV), building transaction cost analysis (TCA) for pre-trade estimation or post-trade measurement, analyzing bid-ask spread decomposition or market impact or information leakage, conducting best execution committee reviews, evaluating payment for order flow (PFOF) arrangements, interpreting Rule 605/606 reports, or handling fixed income or ETF execution via RFQ protocols. Also covers Reg NMS Order Protection Rule and venue fee structures.

Low/high fidelity wireframes, user flows, information architecture, prototyping techniques, and design iteration processes

Validate, lint, audit, or fix bash/shell/.sh scripts via ShellCheck.
