Design documentation is one of the first things cut when project budgets are tight - but it is also one of the most valuable artifacts for construction support, peer review, and future reference. I built an AI-agent tool that captures the complete design trail automatically as a byproduct of the design process itself, requiring zero additional time from the engineer.

My Role

Sole developer. Self-initiated project - identified the documentation gap and built the solution end-to-end.

What I Built

AI agent for automatic design documentation:

  • The tool runs alongside the design process and captures every design change, consideration, assumption, decision, and rationale as the engineer works
  • Produces a single comprehensive design document covering the full design trail - from initial assumptions through final decisions
  • No hallucination - the tool documents what actually happened during the design process, not what an AI thinks should have happened
  • General-purpose - works across project types and disciplines, not tied to a specific software or workflow

Zero-overhead integration:

  • The tool requires no additional design time or documentation time from the engineer
  • It captures the design narrative as a natural byproduct of the work being done
  • The output is a structured, readable document that can be included directly in the project deliverables

Impact

  • Eliminates manual documentation effort entirely - design trail is captured automatically
  • First deployed on a UV treatment facility detailed design project where the documentation budget was limited
  • The project manager was impressed by the completeness and quality of the documentation package delivered alongside the drawings
  • Applicable across all projects - particularly valuable on budget-constrained work where traditional documentation time is not available

Technical Approach

Python-based AI agent leveraging large language models for context-aware capture and summarization of design decisions. The agent observes the design process and distills it into structured documentation without introducing fabricated content.
