Pairs code-work and code-verification for strict scope control, test-backed changes, adaptive parallelism, and fresh independent evidence.

code-verification
Independently review, test, diagnose, and verify software against explicit requirements, repository standards, and material risks using traceable fresh evidence. Use when Codex is asked to review code or a diff, inspect a pull request, diagnose a failing check without changing code, run or assess tests, validate a bug fix or feature, audit code quality, identify coverage gaps, judge release readiness, or report whether an implementation is correct. Default to read-only source inspection and existing checks; create or change tests only when explicitly requested, and do not modify production code unless the user separately authorizes a fix.
code-work
Implement, modify, refactor, debug, and maintain software with strict scope control, repository-aware planning, root-cause analysis, incremental test-backed changes, adaptive parallelism, and fresh verification evidence. Use when Codex is asked to write or change production code, fix a defect, implement a feature, refactor a component, perform a migration, or complete another coding task that authorizes source changes. Use code-verification instead when the primary request is read-only review, testing, diagnosis, audit, or validation.
