I Built a Claude Code Toolkit That Checks Copy Traders Before You Copy Them

This story was originally published on HackerNoon at: https://hackernoon.com/i-built-a-claude-code-toolkit-that-checks-copy-traders-before-you-copy-them .

In one week the trader I copy lost about 4% and my copy lost about 28%. So I built Strike Copilot, a free, open-source toolkit for Claude Code that checks traders and replays them on your own settings before you copy them. It can't place orders or withdraw, keeps your API key on your computer, and shows a dry run before every change. The main lesson: let scripts do the maths and let the AI explain it.

This story was originally published on HackerNoon at: https://hackernoon.com/a-borrower-pays-euro100-where-does-the-money-go . How payment allocation exposes a deeper Financial Product Engineering challenge: turning financial intent into precise, reliable, evolvable software behavior.

This story was written by: @adamsaghy . Learn more about this writer by checking @adamsaghy's about page, and for more stories, please visit hackernoon.com . A €100 borrower payment has no universal destination — its allocation across past-due, due, and future installments, and across principal, interest, fees, and penalties, is a policy decision. Financial Product Engineering turns a lender's intent into precise, deterministic, evolvable software behavior: configurability with exact semantics, chronological event processing, rule changes that preserve existing contracts, and testing lifecycles, not calculations.

B2B verification's problem isn't the rules but the design. Dumb friction — repeated data entry, unexplained requests, vague statuses — should become smart friction: relevant controls, reused evidence, clear next steps. The framework: start from the evidence journey, not the form; define purpose, source, freshness, confidence, action per item; layer experience, orchestration, evidence, policy, records; design for business, operator, auditor; measure speed with control quality.
