Civ Grounded Development

Enforce repository-grounded development. Read relevant code first, map existing mechanisms, then implement inside the current architecture and data model.

Mandatory Workflow

1. Scope the request in one sentence.
2. Identify affected domain: logic, config, components, hooks, utils, workers.
3. Read current implementation before proposing changes:
   • Start from references/system-map.md.
   • Read the specific modules actually used by the feature.
   • Trace imports/exports to confirm data flow and ownership.
4. Write a short "existing mechanism summary" before coding:
   • Current logic path.
   • Economic principle involved (production/consumption/prices/wages/taxes/trade).
   • Numeric system involved (rates, caps, coefficients, thresholds, progression).
   • UI binding path (state source -> component -> interaction/effect).
5. Implement by extending existing system first:
   • Prefer modifying current modules/configs over creating new architecture.
   • Keep logic in existing domain folders (src/logic, src/utils, src/config).
   • Keep UI style and interaction patterns consistent with existing components.
6. Add concise Chinese comments only for non-obvious logic.
7. Validate with available checks (npm run lint, npm run build) when feasible.
8. Report results with:
   • What was reused.
   • What changed.
   • Why changes stay within project architecture.

Hard Constraints

• Do not create a parallel system when an existing path can be extended.
• Do not rewrite core mechanics without reading current implementations first.
• Do not introduce a new data model for economy/logic/UI unless existing models are insufficient.
• If a new subsystem is unavoidable, state this explicitly and ask user confirmation before implementation.

Reuse Decision Rule

1. Can current module be extended with a small change? Extend it.
2. Can behavior be config-driven in existing config files? Do that.
3. Can shared utility cover it with minor addition? Add to current utility.
4. Only when all above fail, propose a new subsystem and request confirmation.

Output Requirements

Before coding, output a brief "grounding note" with:

• Related files read.
• Existing mechanism summary.
• Reuse-first implementation plan.

After coding, output a brief "alignment note" with:

• Existing systems reused.
• Numeric/economic consistency checks.
• Any unavoidable new abstraction and user confirmation status.

Resources

• references/system-map.md: quick read order and key files for architecture, logic, economy, numeric balance, and UI bindings.
