Worked on enhancing error handling and documentation for the moysklad/api-remap-1.2-doc and moysklad/api-remap-1.2-doc-in repositories, focusing on downtime scenarios. Introduced a new error code, 1095, to clearly indicate temporary unavailability, and provided user-facing descriptions with retry guidance to improve developer experience during outages. Applied Markdown to update and standardize documentation formatting, ensuring consistency and readability across repositories. Emphasized API design and technical writing skills to align error messaging and documentation structure. The work contributed to improved maintainability and reduced support overhead by making error states and recovery steps more transparent for users and internal teams.
