Design architecture foundations before implementation. Use when asked to design or refactor architecture, choose Rust/Go crate, package, module, runtime, workflow, or service boundaries, compare mature project architecture, prevent stacked one-off PRs, audit migration debt in existing repos, or produce a spec before coding.
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
# Architecture Foundation ## Overview Use this skill to turn an architecture discussion into explicit boundaries, contracts, validation gates, and a small execution plan. The goal is not to copy an admired project, but to identify the project's shape and choose the minimum architecture that keeps ownership, effects, errors, and tests clear. For large existing repos, first explain the architecture they already have, then decide whether the work is boundary creation, boundary completion, or boundary deletion. ## When To Use - The user asks "what architecture should this use?", "is this stacked work?", "make a complete spec", "design the runtime", or "compare good libraries". - The change touches runtime, state ownership, adapters, plugins, event loops, rendering, schedulers, persistence, or cross-module contracts. - A repo has many issues/PRs that look individually valid but may not converge on one architecture. - A mature repo has duplicated paths, compatibility shims, generated configs, workflow definitions, or docs that may disagree about the source of truth. - A new skill, framework, library, or large feature needs a foundation guide before implementation. …

How to install
mdr add majiayu000/spellbook/architecture-foundation@sha256:37bdec7d1e5c8449The line at the top of this page pins the label git:20260605.a09e45c, 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.
