Use for agent tasks in native Windows that need file edits, text conversion, JSON processing, or shell commands with quoting or encoding problems. Prefer Python for these operations. Do not apply Windows shell rules to macOS, Linux, or WSL.
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
# Windows Python First Worker entrypoint. Confirm that the task runs in native Windows before using these rules. Use Python for file and text operations in native Windows. Use PowerShell to launch programs and for Windows APIs that require it. Keep direct Git, build, and test commands when they already work. ## Select the runtime Confirm the OS and the shell from the tool context. If needed, use `$PSVersionTable.PSVersion` to identify the PowerShell version. A Windows host can run a WSL shell. Use Linux rules inside WSL. Use the project's Python interpreter when it has one. Otherwise, check `py -3 --version`. If that command is unavailable, check `python --version`. Confirm Python 3 and its executable path before use. A command name alone does not prove that an interpreter is installed. For file and text work, launch the selected interpreter with `-X utf8`. This enables Python UTF-8 mode. It does not change the encoding of other programs or prove that PowerShell will decode their output correctly. …

How to install
mdr add ancienttwo/repo-harness/windows-python-first@sha256:de7045013bced4f4The line at the top of this page pins the label git:20261010.a2dbbbb, 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.
