Building With Claude: The Prompt Playbook
The difference between a vague AI chat and a working strategy is knowing exactly what to ask for at each stage. This is that playbook — five stages, the specific mistakes to catch, and a full copy-and-paste prompt library.
- Prompts for all 5 stages: idea → rule → backtest → debugging → deployment
- The full library, filterable by stage, with one-click copy
- Real tooling by name: NinjaScript, MQL5, ccxt, CrossTrade, Databento
- The failure modes of AI-generated trading code — and the prompts that catch them
DAY
Five stages. One library.
No vague chats.
Idea → Precise Rule
The prompts that turn "I keep noticing…" into a rule specific enough that two people would find the same trades.
Rule → Honest Backtest
Backtest-build prompts with the out-of-sample holdout and cost modeling written in from the first message.
Reading Results Together
How to interrogate what Claude hands back — the questions that surface look-ahead bias and quiet overfitting.
Debugging & Porting
When it breaks — and the porting prompts for NinjaScript, MQL5 and ccxt when it's time to go live.
The Full Library
Every prompt in one filterable place with one-click copy — 28 and growing with free updates.
Two Editions
The interactive HTML playbook plus a clean PDF reading edition — both in one download, yours forever.
A library you copy from,
not a lecture you forget.
Idea → precise rule
The stage-one prompts — sharpening a hunch into something testable before any code exists.
Copy, paste, build
Every prompt in the playbook, filterable by stage — from sharpening an idea to guarding against look-ahead bias.
The AI-code failure modes
The specific ways AI-generated trading code goes wrong, so you catch them in the chat — not in your account.
Actual screens from the playbook · works offline, no account needed.
Everything you might be wondering.
It's written for Claude — the same assistant the founder uses to build her own systems — but the prompts are plain English and the method transfers to any capable coding assistant.
No. That's the point — the prompts do the technical specification for you, and the playbook teaches you to read and question what comes back, which matters far more than syntax.
They pair well but stand alone. The Starter Kit teaches the whole path; this playbook goes deep on one stage of it — the actual building-with-Claude conversation.
One download with both editions: the interactive HTML playbook (filterable library, one-click copy, works offline) and a clean PDF reading edition with every prompt printed in full.
