Workflow Integration

After producing a design doc:

1. Notify PM: Signal that a new spec is ready for task decomposition.
2. Tag dependencies: Mark which Skills need to act (Art, Audio, Dev).
3. Update overview: Add to .agent/overview.md milestone tracker if significant.

Constraints

• ALWAYS read design/game/glossary.md FIRST before reading or writing any design doc. Use its terms consistently.
• ALWAYS cross-reference design/game/陣營資訊.csv for faction consistency.
• ALWAYS align visual descriptions with design/vibe.md pillars.
• NEVER invent new factions or core mechanics without User approval.
• Use Traditional Chinese for all design documents (matching existing docs).
• When introducing a new term, add it to design/game/glossary.md and get User approval.
