VX Agent Workflow — Token-Efficient Command Execution

Core principle: Use vx rg as the universal cross-platform filter. Never use platform-specific tools like Select-String (PowerShell), grep (Unix), or findstr (cmd). One command, every OS.

Why This Matters

AI agents pay per-token for both input and output. A full cargo test run can produce 500+ lines when you only need the 5 lines showing failures. Agents that dump raw output waste 95% of their context window on noise.

The vx advantage: vx auto-installs rg (ripgrep), jq, fd, and other filtering tools on every platform. Use them instead of shell-specific builtins.

Token Savings Per Operation (Measured)
