In the pack: ChatGPT, Claude & Gemini Prompts for Coding and Developers
Trace One Request Through the Codebase
Prompt
Stack: {{FRAMEWORK}}
The trigger (route, CLI command, queue message or UI action): {{TRIGGER}}
Code along the path (handlers, middleware, services, data access, in call order if I know it): {{CODE_PATH}}
The question I'm trying to answer: {{QUESTION}}
Produce:
1. A numbered trace: each step names the file and function, what it receives, what it does, and what it passes on. Note where the data changes shape.
2. Every branch point that changes the outcome (auth checks, feature flags, validation, cache hits, retries), with the condition quoted.
3. Every place the request leaves the process: database queries, network calls, file writes, messages published.
4. A short sequence diagram in Mermaid syntax.
5. The direct answer to my question, citing the steps that prove it.
6. Gaps: any step where the code I pasted stops and you'd need another file to be sure. Name the file or symbol you'd need.
Do not fill gaps with plausible framework behavior unless you label it "framework default, verify".
