Living documentation

As explained in The Art of Code

Living documentation is documentation automatically generated or maintained through the development process so that it reflects the current state of a system.

Living documentation is generated or maintained through development so it reflects the system’s current state with minimal updating effort. It preserves useful reasoning alongside implementation. section 3.2.1

From development artifacts to durable context

OpenAPI specifications and Cucumber scenarios can generate documentation as part of development. A bug-fix analysis can also record the error, root cause, alternatives, and chosen design decision for future maintainers. section 3.2.1 section 3.2.1

Use living documentation deliberately:

  • Keep it accurate and current; outdated documentation can mislead developers and AI agents. section 3.2.1
  • Store valuable reports and reviews in the codebase when they explain constraints, boundaries, decisions, or deferred improvements. section 3.2.1

How The Art of Code covers it

How deep it goes
Defines automated generation and maintenance, explains its value and risk, but stops short of prescribing an implementation workflow.
Examples
Uses OpenAPI specifications, Cucumber scenarios, bug-fix analyses, sustainability reviews, and stored design decisions as documentation artifacts.
What you can do after
Apply it through OpenAPI specifications, Cucumber scenarios, and codebase records that preserve current system context.
How it connects
Connects OpenAPI specifications, Cucumber scenarios, design decisions, technical constraints, architectural boundaries, and AI agents.
