codebase-walkthrough

What problem does it solve?

It prevents wasted implementation time by helping you understand exactly how the codebase handles a task end-to-end before you start changing anything.

Core Features & Use Cases

• Flow-first walkthroughs: builds an end-to-end journey diagram (main path plus side effects) and walks every leg including persistence and downstream consumers.
• Code-grounded explanations: shows the relevant file paths, line ranges, and key function signatures/code blocks (without dumping entire files) for each leg of the flow.
• Change impact mapping: links the ticket’s changes to the specific affected legs, files, and before/after data shapes.
• Implementation-ready reading list: produces a prioritized “files to read” list limited to directly relevant and essential context files.
• Assumptions surfaced early: explicitly calls out assumptions and open questions, marking what must be verified rather than guessed.

Quick Start

Ask the AI to run a deep walkthrough for your ticket or task so it traces the full flow (including side effects and code) before proposing any implementation changes.
