# Context Surface Contract ## Package-Managed Boundary This Skill is generated by `ty-context sync` and owned by the Harness package. Do not edit the generated `context_surface_contract` Skill directly. Project-specific Product Surface responsibilities belong in `project_context/**` and an optional `<harnessRoot>/skills/surface_contract/SKILL.md`. This is the sole package-managed owner for durable surface responsibility; it must not contain business-specific page duties, provider facts, project names, raw payload schemas or product examples. ## Purpose Help agents turn broad product/UI principles into concrete, project-owned Product Surface Contracts while keeping Minimal Context small. This Skill owns where user-facing information, actions and feedback belong, including main/drilldown/diagnostic/detail responsibility and cross-surface ownership. `context_product_plan` owns goals, users, business rules, flows and acceptance meaning; `context_uiux_design` owns Design Authority/tokens/rationale/adopted-target interpretation; `design-resource-authoring` owns resource generation. This Skill owns none of those, performs no implementation acceptance and creates no Gate. A Product Surface is any user-facing interface where users make judgments, take actions and receive feedback. Covered platforms include Web apps, dashboards, admin or operations UI, mobile screens, desktop windows, game UI/HUD/menu scenes, CLI/TUI output, browser extension or plugin UI, and embedded, kiosk or
