Use when designing systems, structuring code, reviewing diffs, handling state, or adhering to core software engineering discipline principles.
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
# Engineering Principles Suite A catalogue of 21 foundational principles for software architecture, code quality, state management, and agentic workflows. ## Principles Catalog Read the specific principle file via `view_file` on demand when applying its rule: | Principle | When to Apply | File Path | |---|---|---| | **`boundary-discipline`** | Apply when wiring validation, error handling, or framework adapters. Concentrate guards at system boundaries (CLI, config, network, external APIs); trust internal types and keep business logic in pure functions. | [`boundary-discipline/SKILL.md`](./boundary-discipline/SKILL.md) | | **`build-the-lever`** | Apply to any non-trivial work, not just bulk work: edits, migrations, analyses, checks. Build the tool that does it or proves it (codemod, script, generator, or a skill your subagents follow) instead of working by hand. The tool is the artifact a reviewer can rerun. | [`build-the-lever/SKILL.md`](./build-the-lever/SKILL.md) | …

How to install
mdr add j-star-films-studios/vibecode-protocol-suite/engineering-principles@sha256:8050fcac9b948511The line at the top of this page pins the label v2.0.0, 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.
