Implements authentication and payment features using Clerk, Supabase Auth, or Stripe. Use when user mentions ログイン, 認証, auth, authentication, Clerk, Supabase, 決済, payment, Stripe, 課金, サブスクリプション. Do NOT load for: 一般的なUI作成, データベース設計, 非認証機能.

Use when implementing Stripe webhook endpoints and getting 'Raw body not available' or signature verification errors - provides raw body parsing solutions and subscription period field fixes across frameworks

Help users explore operation history and time travel in jj. Use when the user explicitly mentions 'operation log', 'op log', 'jj op', or 'operation history'. Covers jj op log, --at-op flag, op restore, and operation exploration.

Integrate payment gateways like Stripe, PayPal, and Square with backends for payment processing, subscription management, and webhook handling. Use when building e-commerce platforms, implementing billing systems, and handling payments securely.

Build and manipulate distance matrices for routing problems. Use this skill when computing travel distances/times between locations, handling geographic coordinates, creating cost matrices, or processing location data for optimization solvers.

Navigate warehouse layouts and calculate efficient paths between locations. Use this skill when working with warehouse grids, aisle structures, rack positions, or calculating travel distances in distribution centers.

Implement routing strategies for warehouse order picking. Use this skill when determining optimal pick sequences, applying heuristic routing methods, calculating travel distances, or optimizing picker movements through storage areas.

Optimize warehouse slot assignments for picking efficiency. Use this skill when determining optimal product locations, minimizing travel time, balancing workload across zones, or reassigning slots based on demand patterns.

Implement Traveling Salesman Problem algorithms for route optimization. Use this skill when finding shortest routes through multiple points, solving pick path problems, implementing nearest neighbor or 2-opt algorithms, or optimizing travel sequences.

Model and optimize warehouse physical layouts. Use this skill when designing aisle configurations, calculating travel paths, defining zones, or analyzing spatial relationships between locations.

Calculate and analyze warehouse picking efficiency metrics. Use this skill when measuring picker productivity, analyzing travel vs pick time ratios, benchmarking performance, or optimizing operational KPIs.

Group orders into efficient batches for picking operations. Use this skill when combining multiple orders for single pick trips, optimizing batch sizes, clustering orders by location proximity, or maximizing picker productivity.

Secret detection patterns and scanning workflow. Auto-loaded by security-reviewer agent for all security audits. Contains regex patterns for 25+ secret types (AWS, Google, GitHub, Stripe, etc.) and CLI scanning commands.

UX research and analysis for identifying gaps, mapping customer journeys, benchmarking against top companies (OpenAI, Apple, Stripe, Notion), and measuring UX success using frameworks like JTBD, Kano Model, Double Diamond, and Service Blueprints.

Foundational reasoning. Use fp: to strip assumptions and rebuild from base truths. Activates axiom-based thinking, not surface analysis.

Apply first-principles thinking to break down complex problems into fundamental truths and rebuild solutions from the ground up. Use when solving strategic decisions, breaking through blockers, or challenging assumptions. Triggers on first principles, Elon Musk methodology, fundamental truths, strip assumptions, physics of the problem, rebuild from scratch.
