Ask Codex CLI (gpt-5.6-sol) to run local app verification that needs computer use, browser automation, simulators, screenshots, app launching, or independent runtime inspection. This is how gpt-5.6-sol is invoked for computer-use work. Use when the user asks Claude to have Codex or gpt-5.6-sol test a flow, verify UI behavior, inspect a running app, capture screenshots, or report confirmation and feedback about implemented behavior.
Ask Codex CLI (gpt-5.6-sol) to implement scoped code changes in the current repository, then have Claude inspect the resulting diff and verification. This is how gpt-5.6-sol is invoked for implementation work. Use when the user asks Claude to delegate implementation to Codex or gpt-5.6-sol, when the model-selection rubric routes the work to gpt-5.6-sol, or when a bounded task would benefit from another coding agent producing a patch.
Ask Codex CLI (gpt-5.6-sol) for an independent code review of uncommitted changes, a branch diff, a commit, or a specific implementation. This is how gpt-5.6-sol is invoked for review work. Use when the user asks Claude to have Codex or gpt-5.6-sol review work, when the model-selection rubric calls for a gpt-5.6-sol review perspective, or when Codex should audit a diff, find bugs or regressions, or compare Claude's implementation against requirements. For a review by Claude itself, use the normal review process instead.
