Worked on the chopratejas/headroom repository to enhance proxy configurability and operational clarity for Anthropic passthrough routing. Focused on updating documentation to support a new command-line interface option, allowing users to specify a custom Anthropic API URL endpoint. Leveraged skills in API integration, CLI design, and Markdown to ensure that deployment instructions and configuration details were clear and accessible. The updates improved onboarding for both operators and developers by providing thorough change logs and best practices for proxy configuration. No major bugs were addressed during this period, with efforts concentrated on feature documentation and improving the overall developer experience.
