Ignoring repository standards
Over-formatting documentation
Treating style as decoration
Prioritizing appearance over clarity
Allowing documentation drift
#Definition of Done
Documentation is considered style-compliant when
- Every document follows the repository's standardized structure, terminology, formatting conventions, engineering philosophy, and documentation lifecycle without unnecessary deviation.
- Writing communicates engineering knowledge through clear, precise, objective, and professional language that minimizes ambiguity while maximizing long-term maintainability.
- Terminology remains consistent across the entire repository so that identical engineering concepts are always described using identical language, definitions, and naming conventions.
- Documentation emphasizes engineering principles, architectural reasoning, operational guidance, decision support, and long-term software quality instead of implementation-specific details whenever practical.
- Every section contributes meaningful engineering value, supports repository cohesion, preserves organizational knowledge, and aligns with established documentation standards.
- Engineering reviews continuously validate clarity, consistency, readability, correctness, completeness, maintainability, accessibility, and repository alignment before publication.
- Documentation evolves through disciplined governance, version management, structured reviews, terminology control, and continuous refinement while preserving backward consistency across the repository.
- Repository-wide writing standards remain stable enough that engineers experience every document as part of a single, unified engineering knowledge system rather than independent articles.
- The documentation consistently demonstrates engineering discipline, professional communication, architectural clarity, operational maturity, maintainability, and long-term knowledge preservation.
- The repository continues to improve without sacrificing consistency, readability, discoverability, or engineering quality.
Exceptional engineering documentation is immediately recognizable.
Every document follows a familiar structure, every concept is described with consistent terminology, every engineering decision is communicated with precision, and the repository grows into a unified body of engineering knowledge where readers focus entirely on understanding systems rather than interpreting documentation styles.
