What problem does it solve? This Skill enforces mdeai-specific conventions when working with Linear issues, preventing bare issue numbers, title-only descriptions, and premature Done states across the sanjiovani workspace. ## Core Features & Use Cases - Executable Issue Descriptions: Generates full issue skeletons with lettered completion-step checklists (A1–E5), Mermaid Gantt diagrams, and persona-first plain-language summaries. - Issue Lifecycle Workflows: Covers creation, update, and Done-gate workflows including branch naming (ai/san-NNN-spec-id-slug), PR magic words (Closes SAN-NNN), and progress tracker sync with todo.md and changelog.md. - Use Case: When asked to create a Linear issue for a launch P0 task, the Skill drafts a complete description with completion steps, a Gantt chart, required labels (phase:launch, prefix, stack), and creates it via the Linear MCP save_issue tool. ## Quick Start Ask the agent to create a Linear issue for a specific task and it will draft the full executable description with checklist, Gantt diagram, and labels before saving it to the sanjiovani workspace.
