# David Grimsley Full Agent Context > Fuller AI-agent context for David Grimsley's public portfolio, public APIs, MCP servers, production apps, and Quantum API integration guides. Start with `/llms.txt` for the short index. This file uses plain Markdown intentionally. Canonical site origin: `https://davidjgrimsley.com` ## Quantum API - Human page: `/public-facing/api/quantum` - Agent Markdown: `/public-facing/api/quantum.md` - Direct API base URL: `https://davidjgrimsley.com/public-facing/api/quantum/v1` - Live OpenAPI: `/public-facing/api/quantum/openapi.json` - Live endpoint directory: `/public-facing/api/quantum/v1/portfolio.json` Use the OpenAPI document for exact current endpoint schemas. The portfolio document lists the current public API surface and request-ready mounted paths. Authentication summary: - Health and portfolio metadata are public. - Runtime endpoints normally use `X-API-Key`. - Key management and IBM profile endpoints use the signed-in user's bearer token. - Never invent or expose credentials, IBM tokens, API keys, or private service state. ## Plugin & Package Guides - Quantum API Unreal Plugin: `/public-facing/api/quantum/ue-plugin.md` (`QuantumApi`, UE 5.8 Runtime plugin, version `0.2.0-beta`) - TypeScript SDK: `/public-facing/api/quantum/typescript-sdk.md` (`@mr.dj2u/quantum-api`, version `0.1.2`) - Python SDK: `/public-facing/api/quantum/python-sdk.md` (`quantum-api-sdk`, version `0.1.0`) - Godot Addon: `/public-facing/api/quantum/godot-addon.md` (Godot 4 runtime addon) - Unity Package: `/public-facing/api/quantum/unity-package.md` (`com.quantumapi.runtime`, Unity 2021.3+, version `0.1.0`) Each guide has a human companion at the same path without `.md`. The human page advertises its Markdown companion with `rel="alternate" type="text/markdown"` and points to `/llms.txt` with `rel="describedby"`. Important Unreal beginner point: “What does ‘array of Quantum Api Circuit Operation’ mean?” It means a list of gate steps. A struct is a bundle of fields, an array is a list, and each `Quantum Api Circuit Operation` is one gate instruction such as applying an H gate to qubit 0. ## Public MCP Resources - Human MCP index: `/public-facing/mcp` - App MCP server: `/public-facing/mcp/mrdj-app-mcp` - Pokemon MCP server: `/public-facing/mcp/mrdj-pokemon-mcp` ## Discovery - Root agent index: `/llms.txt` - Full agent context: `/llms-full.txt` - Sitemap: `/sitemap.xml` - Robots policy: `/robots.txt`
