Choose AI tools by where the source of truth lives

The best AI tool for a task often depends on where its source of truth lives.
In “Grok for the browser. Codex for the repository.” I suggest a simple starting point: use Grok when the relevant evidence is in the browser, and Codex when it is in the codebase. Their capabilities overlap, but that is less important than how many boundaries the work must cross to reach the evidence.
This matters in practical AI systems because tool selection is also context selection. Keeping the work close to its source of truth gives the agent a clearer operating environment and reduces unnecessary handoffs.
