Handle cross-platform compatibility including file paths, environment detection, platform-specific dependencies, and testing across Windows, macOS, and Linux. Use when dealing with platform-specific code or OS compatibility.
Use when creating, modifying, debugging, or scaffolding OMP extensions, slash commands, custom tools, event hooks, TUI primitives, ExtensionAPI integrations, .omp/extensions, .omp/commands, .omp/tools, package.json omp.extensions, or OMP lifecycle handlers.
Design Director state machine for `/supi:ui-design`. Drives 9 model-owned phases from scope selection through user review, producing a validated HTML mockup artifact.
Guides the harness-engineering pipeline — turn a codebase into one that resists agentic slop with agent-neutral docs, mechanically enforced architecture, and three runtime guardrails
Gray-area extraction stage — surfaces decisions the user must make before the plan can be authored, without expanding scope
Structured extraction of the user's seed prompt into a typed intake artifact — first stage of the UltraPlan authoring pipeline
Per-stack research stage — produces library choices, established patterns, pitfalls, and test architecture for one applicable stack
Requirement coverage checker — verifies every intake success criterion maps to a scenario, no scope creep exists, and deferred ideas are not silently included
