Guides transaction processing: ACID guarantees for financial operations, idempotency (idempotency keys, deduplication), distributed transactions (saga with compensating transactions), settlement workflows, batch processing, reconciliation, and transaction lifecycle state management. Use when implementing payment flows or financial operations.
npx claudepluginhub rnavarych/alpha-engineer --plugin domain-fintechThis skill is limited to using the following tools:
- Implementing atomic balance transfers with correct isolation levels
Designs and optimizes AI agent action spaces, tool definitions, observation formats, error recovery, and context for higher task completion rates.
Designs, implements, and audits WCAG 2.2 AA accessible UIs for Web (ARIA/HTML5), iOS (SwiftUI traits), and Android (Compose semantics). Audits code for compliance gaps.
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.
