AGENTS (Repository Guidance)

Repository Intent

The web/desktop and web/mobile folders host the live HUD demo (Desktop and mobile). Keep everything that should be served from a webserver inside those folders.
docs/game_rulebook.md is the Single Source of Truth (SSOT) for Galaxy Forge’s game logic, builder system, resources, and requirements. Any UI work, game behavior, or rules must align with — not contradict — that document unless a new decision is logged.
docs/ stores documentation while planning/ holds sketches/notes that are not meant for deployment.

Reference SSOT first. When implementing features or answering questions related to game balance, resources, blueprints, buildings, or world generation, open docs/game_rulebook.md and confirm compliance. Note any missing detail needs a Decision Log entry (see section 13).
Respect folder intent. Changes to web assets go in web/desktop or web/mobile only. Use planning/ for drafts and docs/ for textual explanations.
Document assumptions. If you must deviate from docs/game_rulebook.md, append an entry to the Decision Log (section 13) explaining the why/when.
Keep mobile/desktop aligned. When adjusting UI/partials, mirror updates in both web/desktop and web/mobile unless the change is explicitly mobile-only or desktop-only and documented.
Speak German. All explanations, comments, and user-facing text from agents must be in German unless the user explicitly requests otherwise in another language.
Smoke tests mandatory. After every change touching runtime code or assets, perform a smoke test (e.g., php -S localhost:8000 -t web/desktop/public) and note the outcome before wrapping up.

Expand docs/game_rulebook.md if you update core rules, flow, or systems described there. Keep numbering/sections intact; append entries in the Decision Log (section 13) with dates.
The root README.md should mention where to find the SSOT and purpose of each folder.

Section 13 of docs/game_rulebook.md is the Decision Log. Add a dated entry whenever:
- You introduce a new rule variant or exception.
- The implementation deviates from the documented defaults.
