# Outcome Produce a concrete, reviewable result for the workflow below without overstating what was observed, executed, or verified. ## Compatibility Portable across Claude Code, Codex, and OpenCode. The optional matrix generator requires Python 3.11, reads JSON, writes only an explicit output path, and runs no commands. Adapt process and signal tests to the supported operating systems and CLI framework. ## Use this skill when - An existing or new Python CLI needs a focused test architecture. - A repository-wide test strategy also needs a CLI-specific matrix for help, streams, exit statuses, stdin, and shell invocation; also use `python-test-architecture`. - Framework-runner tests miss installed entry-point, process, stream, signal, or platform behavior. - Tests need safe isolation for home/config, environment, stdin, filesystem, TTY, or external boundaries. - A risk-based CLI CI matrix and stable output assertions are required. ## Do not use this skill when - The task is the full Python project's unit/integration strategy without a CLI-specific test deliverable; use `python-test-architecture`. - The task is merely to execute or report an already-defined smoke or health command without changing test design or test code. - The task is to define exit statuses, stream policy, or error schema; use `python-cli-error-output` first. - The task is to redesign commands/options/help rather than verify them; use `python-cli-command-design`. ## Inputs Inspect or obtain: -
