Use when writing or changing a Python command-line interface — a CLI tool, or a command added to a service of either family — its commands and their arguments, the exit code each outcome leaves, and the test that invokes them. Owns the thin command that parses its arguments, calls one ordinary typed function and renders its result, the exit-code map written once at the boundary with success alone at zero, every catalogue failure on a non-zero code of its own and an unexpected exception keeping…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python CLI — commands, exit codes and their test A command-line interface is a boundary like any other: arguments come in as strings, a result and an exit code go out, and everything between is ordinary typed code that knows nothing about the command line. This skill owns that boundary — the command, the exit-code map and the test that drives it — for a CLI tool and for a command added to a service. It gives no package layout for a large command tree. ## When to use vs. neighbours - Whether a CLI tool takes the hex or the flat family → `architecture-choice`; it takes neither, and this skill is what binds its commands. - The settings a command builds, a dotenv file, a tunable's default, an argument versus a setting → `python-settings` (rules 2, 5, 13 and 15). - What goes to stdout and what to stderr, and where logging is configured → `python-logging`. - Declaring the console script, the src layout, the lint and type-check configuration → `python-toolchain`. - The error classes, their `code` and `context`, and rendering a caught error in one place → `exception-catalog`. - What a test asserts, the substitution ladder, the entrypoint layer's budget → `test-principles`. …

How to install
mdr add wntic/pyhouse/python-cli@sha256:32bd08c711dfc4bdThe line at the top of this page pins the label git:20261011.122368f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
