What problem does it solve? Game GUI features often depend on configuration data, and manually keeping Excel source tables in sync with their exported *_data.lua mirrors is error-prone. This Skill automates Phase 4 of the Atom Game GUI pipeline by editing design/tables Excel sources and propagating identical changes to the corresponding *_data.lua files without human interruption. ## Core Features & Use Cases - Excel source table editing: Modifies the authoritative Excel config tables under design/tables as the single source of truth. - Tool-first export with manual fallback: Prefers formal export tools (GDE CLI, excel-config, excel-mcp) to regenerate *_data.lua; falls back to hand-mirroring with a TODO(simulated export) marker when tools are unavailable. - Structured subagent reporting: Returns edited/skipped/blocked status plus changed files and degradation notes to the orchestrator, which records run state centrally. - Use Case: While building a new Bag panel batch-sell button, a subagent adds the new item config rows to the Excel table and mirrors them into bag_data.lua so the runtime and later pipeline phases immediately see the new configuration. ## Quick Start Ask the agent to run the gui-config phase for a panel whose feature requires new configuration data, providing the panel ID and the config fields to add.
