Master API Error Design with AI-Driven Solutions

Master API Error Design with AI-Driven Solutions

This AI agent skill assists developers in designing the error surface of public APIs, enabling seamless self-service error resolution. It provides a structured approach to implementing a machine-readable error-code taxonomy, using a flat catalog, code/subcode, and Google-style domain/reason formats, along with utilizing the RFC 9457 problem-details envelope supplemented by extension members.

What this skill does

• Creates a machine-readable error-code taxonomy for categorizing API errors efficiently.
• Implements the RFC 9457 problem-details standard to standardize error responses.
• Generates actionable error messages that guide integrators towards resolution without the need for external support.
• Signals retryability, including retryable flags and Retry-After headers, for relevant API error scenarios.
• Provides comprehensive per-endpoint error documentation and logs request IDs for better tracking.

Who it is for

• API developers looking to enhance the error handling capabilities of their public APIs.
• Development teams utilizing AI coding agents like Claude Code, Cursor, and Codex for improved API management.
• Technical writers documenting API error handling processes and procedures.

Use cases

• Automating the design of error responses for a newly developed API to ensure integrators can address issues independently.
• Refining existing API error handling by adopting a standardized error-code taxonomy and detailed error responses.
• Improving self-service support capabilities by providing clear, actionable error messages and retry signals.
• Implementing comprehensive error documentation for development teams to reduce support ticket volume.

Technical details

This skill utilizes agent-skills and aiapplication components designed for API error design. It is compatible with AI coding agents such as Claude Code, Cursor, and Codex, aiding in the precise design and response alignment of public APIs to follow standardized formats such as RFC 9457 and application/problem+json.
