Practical setups and field guides — wiring a code graph into your agent, and finding your way around codebases you didn't write.

The problem

• Why your AI coding agent burns tokens — and how a code map fixes itThe token math behind agent file-crawling, and why a queryable graph is 30–90× leaner on discovery.

Set up your agent

• Give Claude Code a map of your codebaseStop Claude Code from crawling your repo file by file. OpenVisio serves a queryable code graph over MCP — setup takes two commands, and tokens drop 30–90× on discovery.
• Give Cursor a map of your codebaseStop Cursor from crawling your repo file by file. OpenVisio serves a queryable code graph over MCP — setup takes two commands, and tokens drop 30–90× on discovery.
• Give Codex a map of your codebaseStop Codex from crawling your repo file by file. OpenVisio serves a queryable code graph over MCP — setup takes two commands, and tokens drop 30–90× on discovery.
