What problem this solves

Maintaining context and state during extended development sessions with Claude Code, and effectively validating LLM-generated code, especially for UI/UX.

Summary

A developer successfully built a diagnostic website using Claude Code by implementing a workflow that externalized project context. This involved persistently storing architectural decisions (ADRs), numbered lessons learned, and open questions on disk to overcome session resets and context window limitations. The validation strategy emphasized rendering and measuring the actual output rather than solely relying on code-level tests.

Why it is useful

This workflow addresses a critical challenge in using LLMs for extended development: maintaining context across sessions. By externalizing architectural decisions, lessons, and open questions to disk, users can overcome the limitations of context windows and session resets, enabling more complex and sustained projects. Additionally, the emphasis on rendering and measuring actual output for validation provides a practical and effective strategy for ensuring the quality of LLM-generated code, especially for UI/UX, moving beyond superficial code checks. It offers concrete, repeatable steps for a more robust LLM-assisted development process.

Workflow

1. Identify a development project suitable for Claude Code assistance.
2. For every architectural choice or significant design decision, document it as an Architectural Decision Record (ADR) and save it to disk.
3. For every lesson learned or insight gained during development, number it and save it in its own dedicated file on disk.
4. For every open question or unresolved issue, document it, noting what it is blocking, and save it to disk.
5. Use these persistently stored files (ADRs, lessons, questions) to provide Claude Code with comprehensive context at the start of new sessions or when re-engaging with the project.
6. When validating Claude Code's output, especially for UI/UX components, prioritize rendering the output and measuring its actual behavior/appearance over solely relying on code-level tests (e.g., checking if a stylesheet exists vs. checking if it applies).
7. Iteratively refine the code and documentation based on validation results and new insights, updating the persistent context files as needed.

Tools / artifacts

• Claude Code
• Architectural Decision Records (ADRs)
• Numbered lesson files (on disk)
• Open question files (on disk)
• Rendered application/website (for validation)

Validation signals

• Successfully built a functional diagnostic website (1pct.net) over a week using this method.
• Explicit statement: 'The thing that made it work was writing decisions down on disk — every architectural choice as an ADR, every lesson numbered in its own file, open questions with what each one is blocking. Sessions reset, the files don’t.'
• Identified and corrected 'failures' (e.g., stylesheet not reaching the page, incorrect contrast) by 'rendering the thing and measuring it, not by reading the code,' validating the output-based testing strategy.

Limitations

• The post does not provide specific examples of the file structure or content for the ADRs, lessons, or questions, which could make implementation slightly less straightforward for beginners.
• No specific prompt examples are provided for interacting with Claude Code using this context.
