Classify the layer
Route the task to UI, dependencies, containers, infrastructure, APIs, auth, AI tools, security, data, or internal policy before choosing a source.
A structured source map for AI coding agents.
The atlas organizes the registries, package indexes, documentation sources, marketplaces, catalogs, and review checks that agents need before they make implementation decisions.
Purpose
Better source selection for better agent output.
RegistryRouter uses the atlas to help agents distinguish official implementation sources from discovery material, examples, marketplaces, community lists, and policy-controlled systems.
Prefer authority
Use official registries, docs, package indexes, vendor references, and internal catalogs as implementation authority. Treat examples as discovery unless verified.
Expose risk
Surface maintenance, license, pricing, secrets, data access, compatibility, and approval checks before the agent changes the codebase.
Coverage
Full-stack registry coverage.
The reference spans the systems agents commonly touch when building modern software.
Layer
Examples
Agent question
Primary risk
UI / frontend
shadcn/ui, Radix, React Aria, MUI
Should this be copied, installed, or custom-built?
Accessibility and visual fit.
Packages
npm, PyPI, Maven, NuGet, crates.io
What is the official package and current install path?
Package identity and supply chain.
Infra / deploy
Docker Hub, Terraform Registry, Artifact Hub
Which provider, module, image, or chart is authoritative?
Permissions, versioning, rollback.
APIs / SaaS
Postman, official API docs, cloud marketplaces
Which docs define auth, rate limits, schemas, and pricing?
Cost, data access, lock-in.
AI / MCP / tools
MCP registries, model hubs, tool catalogs
Can this tool be trusted with the requested data?
Permissions and prompt-injection surface.

}Human-readable now. Structured for agents next.
The long-form atlas is available as a browsable reference. RegistryRouter is designed to expose the same source intelligence through agent-readable records, policy checks, and preflight reports.
Use the atlas as a source map: the goal is not to browse every registry manually, but to give agents a better way to select trusted sources before implementation.
