Ralph Iterative Implementation Loop FAQs

Question 1

What is 'context rot' and how does Ralph fix it?

Accepted Answer

Context rot occurs when a long LLM session accumulates too much history, causing the model to become less accurate. Ralph fixes this by using a 'disk as memory' approach, spawning a brand-new subagent with a fresh context for every single iteration of the build process.

Question 2

What is the 'DONE condition' in the Ralph loop?

Accepted Answer

Before starting an implementation loop, Ralph proposes an observable and unambiguous 'DONE condition' (like 'all acceptance criteria in the spec are met'). This ensures the loop terminates only when the goal is objectively achieved.

Question 3

How does Ralph know what to build?

Accepted Answer

Ralph uses a PLANNING mode to generate a declarative spec file containing goals and acceptance criteria. During the BUILDING phase, it performs a gap analysis against this file to determine the next necessary step.

Question 4

Does Ralph work with any programming language?

Accepted Answer

Yes, Ralph auto-detects your project environment, including languages, frameworks, and test commands, and can be used across any codebase supported by Claude Code.

Question 5

When should I use Ralph instead of normal Claude Code?

Accepted Answer

Use Ralph for large, complex implementations where the amount of code and logic would eventually degrade the quality of a single chat session. For small bug fixes or quick tasks, standard Claude Code is usually faster.
