What is the core philosophy of Outfitter Atlas?

It treats errors as data rather than exceptions and emphasizes 'agent-first' design, ensuring tools provide structured, predictable output that AI agents can reason about.

Why does Outfitter Atlas favor Bun-native APIs?

Utilizing Bun-native APIs like Bun.sqlite and Bun.hash ensures high performance and a zero-dependency footprint, which is ideal for fast-booting tools and microservices.

How does the error taxonomy improve my code?

It maps every failure to one of ten specific categories, automatically providing the correct CLI exit code or HTTP status, allowing both humans and agents to make informed retry decisions.

Can I use this for projects beyond CLI tools?

Absolutely. The Handler contract is transport-agnostic, meaning the same core logic can be exposed via CLI, MCP servers, or standard web APIs without modification.

API開発

Generates architectural patterns and type-safe handlers for building agent-ready Bun applications using the Outfitter infrastructure.

Outfitter Atlas serves as a comprehensive guide and pattern generator for the @outfitter ecosystem, enabling developers to build robust, transport-agnostic infrastructure. It enforces a functional 'Result-first' error handling strategy and a unified handler contract that allows the same logic to serve CLI, MCP, and API surfaces simultaneously. By prioritizing structured output and a strictly mapped error taxonomy, it ensures that your tools are optimized for both human developers and AI agents, fostering predictable behavior across all deployment environments.
