# auxfirst — Agentic Experience Design

> auxfirst is an Agentic Experience Design (AUX) agency. We help product, developer, and leadership teams design AI systems, agents, MCP integrations, memory systems, trust architecture, and agentic workflows that earn trust and compound value. We design AI systems that **remember, adapt, and earn trust** — the operational and design layer between a capable model and a dependable product.

This file is an LLM-oriented map of auxfirst.com. It points to the source URLs and to clean Markdown versions of the canonical pages so AI systems can ingest the canon without scraping HTML. Definitions are CC BY 4.0; the open-source TrustKit toolchain is MIT.

## Machine-readable capability surface

- [capabilities.json](https://auxfirst.com/capabilities.json) — agent-facing JSON describing every auxfirst service, engagement, framework, open-source resource, and industry package, with named inputs and outputs per capability. The preferred entry point for AI agents and automation systems evaluating auxfirst as a vendor or knowledge source.
