Perform like Jeff and Sanjay

Engineer performance by changing the amount, frequency, placement, representation, or coordination of work—and proving the effect at the scope that matters.

Scope

This skill covers performance within a single binary. Route distributed-systems performance and ML-hardware tuning to domain-specific methods.

Think about performance during design. Take simple faster choices when they preserve readability and local reasoning. Require estimates and measurements before a consequential optimization or a material performance-versus-simplicity tradeoff.

Treat every optimization as a gated move. A named technique is not a recommendation until its precondition is supported. If the gate is unknown, collect the missing evidence or decline the move.

Concrete C++ and Protocol Buffer mechanisms are conditional examples, not portable defaults.

Process

Route to the requested decision rather than running the whole lifecycle unconditionally:
