pytest-coverage from marielynneblock/arcanum-artifex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add marielynneblock/arcanum-artifex/pytest-coverage@git:20260710.ffb3400Pins git:20260710.ffb3400 in mdr.lock. Pin the fingerprint instead.

Run pytest tests with coverage, discover lines missing coverage, and increase coverage to 100%.
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
The goal is for the tests to cover all lines of code. Generate a coverage report with: pytest --cov --cov-report=annotate:cov_annotate If you are checking for coverage of a specific module, you can specify it like this: pytest --cov=your_module_name --cov-report=annotate:cov_annotate You can also specify specific tests to run, for example: pytest tests/test_your_module.py --cov=your_module_name --cov-report=annotate:cov_annotate Open the cov_annotate directory to view the annotated source code. There will be one file per source file. If a file has 100% source coverage, it means all lines are covered by tests, so you do not need to open the file. For each file that has less than 100% test coverage, find the matching file in cov_annotate and review the file. If a line starts with a ! (exclamation mark), it means that the line is not covered by tests. Add tests to cover the missing lines. Keep running the tests and improving coverage until all lines are covered.

How to install
mdr add marielynneblock/arcanum-artifex/pytest-coverage@sha256:6721222aee6f22e4The line at the top of this page pins the label git:20260710.ffb3400, 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.
