System Architect Specialist. Use this to design system architecture, creating C4 models and ADRs (Decision Records).
Design a module's interface using parallel sub-agents producing radically different designs ("design it twice"). Compare on depth, simplicity, and efficiency. Embedded grill on the synthesized choice. Use when designing a new API, exploring interface options, or deciding the shape of a refactor before writing code.
Create well-structured RFCs and technical proposals for software projects. Use this skill whenever the user wants to write an RFC, technical proposal, design doc, architecture doc, or system design overview. Also trigger when the user says things like "write an RFC", "I need to propose a new system", "create a technical proposal", "document the architecture", "write up the design", "I need a design doc", or "explain the system architecture in a doc". Even if they just say "RFC", "design doc", or "arch doc", use this skill. Covers both RFCs (proposing what to build) and architecture docs (documenting an existing codebase).
Refactors specified code to improve clarity, reduce duplication, or align with the project's architectural patterns — without changing external behavior. Invoked when the user asks to refactor, clean up, simplify, or restructure code.
Transform a PRD into a technical SPEC document — architecture, API design, data model, error handling, and implementation contracts. Triggers on: prd-to-spec, prd to spec, prd转spec, 需求转设计, 需求转规格, generate spec from prd, design from prd, 技术方案, 设计方案.
Use when designing, reviewing, refactoring, or implementing code that should stay simple, testable, readable, and sustainable. Applies principles for investigating before changes, keeping few layers, making I/O explicit, using dependencies deliberately, organizing by feature, naming consistently, and presenting plans progressively.
Front door of the SDD flow. When the user asks for a feature or bug fix ("implementa…", "agrega…", "arregla…", "add…", "build…", "fix…"), FIRST scan the request + codebase context for load-bearing ambiguity and ask a few targeted clarifying questions (selectable options, recommended first) BEFORE writing any spec or code — then hand a well-formed goal to /opsx:propose (small) or the sdd-feature-flow workflow (large). Skip the questions when the request is already unambiguous. Modeled on GitHub Spec-Kit's /clarify.
Comprehensive knowledge of all 23 Gang of Four design patterns with progressive disclosure (Quick/Practical/Deep), pattern recognition for problem-solving, and philosophy-aligned guidance to prevent over-engineering.
You MUST use this when a request needs design decisions before code — new features, product or UX behavior, architecture changes, unclear success criteria, or two materially different approaches. Explicitly specified mechanical refactors, localized fixes with known expected behavior, and single-outcome config changes go straight to implementation.
Explore requirements and approaches through collaborative dialogue before planning implementation
