What is the Keep the Why Claude Code skill?

Keep the Why is a skill for Claude Code that automatically captures, organizes, and updates the architectural reasoning, rejected alternatives, and constraints behind code changes inside your repository.

How does Keep the Why prevent AI coding regressions?

By explicitly recording why specific technical approaches were rejected or constrained, Keep the Why stops AI agents from repeatedly suggesting solutions that were already tested and discarded.

How are architectural records organized in the codebase?

Knowledge is structured into concise, topic-focused markdown files within a dedicated context folder, tracking evidence levels, status, and revisit triggers alongside the code.

When should Keep the Why be used during development?

Use it during non-trivial architectural decisions, bug workarounds, legacy code analysis, or maintainer offboarding interviews to prevent institutional knowledge loss.

Keep the Why - Claude Code Skill for Architecture Docs

Keep the Why is a repo-native documentation and persistence skill designed to capture the rationale that code alone cannot explain. By tracking architectural decisions, rejected alternatives, operational workarounds, and incident learnings alongside code changes, it prevents AI agents from repeatedly re-suggesting dismissed approaches. It works across continuous workflow capture, legacy code archaeological reconstruction, and structured maintainer offboarding interviews, generating structured, human-and-agent-readable context files that accelerate developer onboarding and make legacy codebases maintainable.
