Godot 4.7 Baseline

• Expert patterns in this skill target Godot 4.7+ (stable, 2026-06-18).
• Consult the Godot 4.7 migration guide when upgrading projects from 4.6.
• NEVER assume 4.6 defaults (stretch mode, audio area_mask, RichTextLabel percent flags) without checking 4.7 migration notes.

NEVER Do (Expert Anti-Patterns)

World Design & Exploration

• NEVER allow "Soft-Locks" where a player is trapped; if they enter via a one-way path ("valve"), they MUST be able to leave using current abilities. Always design fail-safe escape routes.
• NEVER create empty dead ends; if a player backtracks to a remote area, they MUST be rewarded with a collectible, lore, or currency. Empty rooms are design failures.
• NEVER make backtracking purely repetitive; as the player gains movement (Dash/Teleport), traversal through old areas MUST become faster. Open shortcuts to bypass long, early routes.
• NEVER hide the critical path without "crumbs"; use distinct Landmarks, unique lighting, or environmental storytelling to build the player's mental map.
• NEVER design abilities that serve only one purpose; strictly implement dual-use traversal and combat functionality (e.g., a "Dash" that crosses gaps and dodges attacks).
