Port a feature from an existing repository by copying its actual code and editing the copy, so its bug fixes and behavioral nuances survive. Use when asked to copy or port an existing feature (especially an exact copy), when moving one into a different…
Use the local Codex CLI as an independent second agent. Two branches — (1) proactively run `codex review` for a second opinion after completing a substantive change, before presenting it as done or committing; (2) delegate a well-defined implementation task…
Compare screenshots against the intended design, distinguishing approved references from historical baselines. Use for iterative implementation matching, before/after visual review, objective image telemetry, or checking a lone capture for flat, empty, or…
Use the unprimed sub agent as a second set of eyes before accepting visual work — MANDATORY before declaring any user-reported visual bug fixed or claiming a visual change verified; primed eyes pass defects fresh eyes catch.
Write tests that pin real behavior instead of implementation details, config values, or lucky samples. Use when adding tests for new behavior, writing a regression test, fixing a brittle or flaky test, reviewing a test diff, or when a test breaks after a…
Build, debug, or review WebGPU renderer work — three.js/TSL scene layers, node materials, or raw WGSL passes and compute. Use when changing GPU resource layouts, render or compute passes, node materials, bind groups, buffers, shaders, frame orchestration,…
