Route full software-development architecture work from product intent through design, implementation, testing, release, and operations. Use when the user asks for a complete development architecture, wants to know which Spellbook skills to combine, needs an execution path across PRD/spec/API/data/security/performance/release/SRE, or asks to turn an idea or repo into a production-ready engineering plan.
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
# Dev Architecture Playbook ## Purpose Use this as the lifecycle router before starting broad product or architecture work. It chooses the minimum useful skill chain, defines gates, and prevents starting implementation before the required contracts exist. ## Route Classify the request first: | Request | Primary Skills | Output | |---|---|---| | Idea, product direction, or market/user problem | `product-discovery`, `prd-master` | Product brief, user stories, success metrics | | Architecture or module boundaries | `architecture-foundation`, `technical-spec`, `elegant-architecture` | Architecture spec, boundaries, rejected alternatives | | API, auth, data, or schema contract | `api-design`, `auth-security`, `database-patterns`, `data-contract-migrations` | Versioned contracts and migration plan | | UI/product surface | `frontend-design`, `ui-ux-pro-max`, `ui-design-system`, `playwright-automation` | UX flow, component plan, visual checks | | Implementation workflow | `flowguard`, `threads`, `systematic-debugging`, `comprehensive-testing` | Bounded execution, ownership, root-cause debugging, and verification | …

How to install
mdr add majiayu000/spellbook/dev-architecture-playbook@sha256:07237a4e7f3523acThe line at the top of this page pins the label git:20260714.772b398, 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.
