What is the primary purpose of the Agent Recorder Fixtures skill?

It records live HTTP traffic from AI providers and generates Swift code fixtures to be used in deterministic unit tests for the SwiftAgent SDK.

Does this skill support streaming AI responses?

Yes, it is designed to capture and format raw text/event-stream payloads, ensuring that streaming agent behaviors can be replayed accurately in tests.

Which AI platforms can I record with this tool?

It currently supports recording and fixture generation for both OpenAI and Anthropic provider traffic.

Is the generated code ready for immediate use?

Yes, the output is specifically formatted for ReplayHTTPClient, allowing you to paste it directly into your SwiftAgent unit tests.

How does it handle sensitive API keys?

The tool includes built-in redaction for common authorization fields and offers a --no-include-headers flag to prevent secrets from being committed to the repository.

Security & Testing

Generates production-ready Swift test fixtures by recording real-time HTTP interactions with AI providers like OpenAI and Anthropic.

The Agent Recorder Fixtures skill streamlines the development of autonomous AI agents by capturing live network traffic and converting it into deterministic Swift code for unit testing. By recording requests and responses—including complex streaming text, event-streams, and tool calls—it allows developers to keep their test suites perfectly in sync with evolving API payloads without manual mock creation. This tool is essential for debugging agent loops and maintaining high-fidelity provider adapters within the SwiftAgent ecosystem.
