py-rig SKILL.md skillA
py-rig from mudrii/hermesd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mudrii/hermesd/py-rig@git:20260923.e104882Pins git:20260923.e104882 in mdr.lock. Pin the fingerprint instead.

Use this skill when building, reviewing, or refactoring Python code that requires strong maintainability discipline: SRP, DRY, OCP, explicit dependency injection, TDD/ATDD workflow, strict typing, architecture review, and clean project structure. Complements the project's Python AGENTS.md with process rigor.
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
<objective> Apply strict design and testing discipline for Python projects. This skill complements `AGENTS.md`, `.codex/rules/python-patterns.md`, and `.codex/rules/python-idioms.md`. It must stay aligned with all three and applies as an execution discipline layer on top of the project's Python standards. This skill adds execution rigor: - ATDD/TDD workflow - SRP, DRY, and OCP decision rules - explicit dependency injection discipline with a pragmatic carve-out for CLI composition roots - strict type discipline - comment quality standards - structured implementation and review checks - hermesd-specific invariants (cache-preservation, read-only access, panels as OCP seam) If `AGENTS.md` is stricter on any point, follow `AGENTS.md`. </objective> <when_to_use> Use this skill when: - implementing a new feature or behavior increment - refactoring Python code for clearer ownership or testability - reviewing module boundaries or dependency flow - replacing hidden collaborator construction with explicit injection - tightening tests around user-visible or integration behavior - removing `Any` types or tightening weak types in touched code …

How to install
mdr add mudrii/hermesd/py-rig@sha256:b08a03bd3cd0c265The line at the top of this page pins the label git:20260923.e104882, 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.
