What problem does it solve? Software architecture knowledge often lives only in chat sessions or a single stale document, so design decisions, quality gates, and repository conventions drift out of sync with the actual codebase across sessions and agents. ## Core Features & Use Cases - Architecture knowledge base: Builds a progressive-disclosure design tree under docs/design/ with domain indexes and leaf contracts, separating current reality, target architecture, and open decisions. - Repository governance and quality gates: Creates or repairs AGENTS.md plus formatter, linter, type-checker, test, and CI configuration matched to the actual languages in the repository. - ADR-gated decisions and MINE integration: Routes material decisions through digest-bound ADR approval and initializes the MINE execution graph via the mine CLI or MCP tools. - Use Case: When starting a new project or rescuing a repository with stale architecture docs, run this Skill to audit the code, research official documentation, and produce a validated design knowledge base with working quality gates. ## Quick Start Ask the agent to use mine-arch to design the target architecture for this repository and initialize its design knowledge base and quality gates.
