 When you adapt your programming tooling and workflow to JP, you are ensuring
 that you will have access to all of the frontier models, all of the local-first
 open source inference runtimes, and all of the major inference aggregation
 services.
 
+## Architecture / Tool Calling
+
+JP's architecture routes to explicitly configured helper binaries as its list of
+tools the LLM may call upon.
+The current self-dev configuration uses a sub-project, `jp-tools`, (invoked
+through the justfile) to satisfy all the binaries required for understanding
+code, modifying files, interacting with version control, generating RFDs
+covering new features, filing Github issues, and making selected shell
+operations.
+JP does not need any tools to operate, but you will want at least a subset of
+the `jp-tools` collection for your valid developer configuration.

+## Roadmap
+
+JP's direction is planned in the open through Requests for Discussion (RFDs),
+short design documents that precede any significant change.
+The RFD index ([on the web][rfds via web] / [in this repo][rfds local]) is the
+canonical, always-current view of what's proposed, in progress, and decided.
