This should trigger for requests such as Create an OpenSpec change from an issue; Convert a plan into OpenSpec; Update an existing OpenSpec change; Split broad requirements into reviewable OpenSpec changes. Part of Plinth Toolkit

Use when creating or refining a structured Java implementation plan from trusted issue summaries, approved designs, ADRs, OpenSpec changes, existing plans, or a valid combination. The plan records its source artifacts and derivation direction and can remain the execution artifact without requiring OpenSpec. This should trigger for requests such as Create a plan from an issue; Create a plan from OpenSpec; Design an implementation plan; Refine an existing plan. Part of Plinth Toolkit

Use when a sanitized issue summary, requirement summary, or design brief needs technical design exploration before creating ADRs, specifications, or implementation plans. This skill inspects repository context, clarifies material ambiguity, compares feasible approaches and trade-offs, recommends a direction, obtains approval, and identifies ADR candidates. This should trigger for requests such as Explore a design; Compare implementation approaches; Recommend an architecture direction; Clarify technical options before planning. Part of Plinth Toolkit

Use when you need to generate Java project diagrams — including UML sequence diagrams, UML class diagrams, C4 model diagrams, UML state machine diagrams, UML Deployment Diagrams, ER (Entity Relationship) diagrams, and bounded-context diagrams — through a modular, step-based interactive process that adapts to your specific visualization needs.
