New Script

/new-script — Unity C# Script Scaffold

Create a new C# script that follows .claude/rules/tech_defaults.md exactly, and — because the user is a Unity beginner — always explain where it goes and how to wire it up.

Steps

1. Ask (or infer from context): class name, feature area (Flood / Weather / XR / UI), and what it should do.
2. Confirm the Unity project exists (unity/Assets/ present). If not, stop — scripts have nowhere to live before Phase 0's Unity project is created.
3. Create the file at unity/Assets/Scripts/<Feature>/<ClassName>.cs. Filename must match the class name.
4. Follow the template and conventions below.
5. Tell the user, step by step: which GameObject to attach it to, which Inspector fields to fill in, and what they should see when they press Play (the eye-verification step).

Template

using System.Collections;

using UnityEngine;

/// <summary>
/// One sentence: what this component does and what it attaches to.
/// </summary>
public class ClassName : MonoBehaviour
{
    [Header("Settings")]
    [SerializeField] private float exampleValue = 1f;

    [Header("References")]
    [SerializeField] private Transform exampleTarget;

    private void Awake()
    {
        // Cache components here — never GetComponent<X>() in Update().
    }

    private void Update()
    {
        // No allocations here: no `new`, no LINQ, no string concat, no Find().
    }
}

Convention checklist (enforce all of these)

• [SerializeField] private for Inspector-exposed fields — never bare public fields.
• PascalCase class/methods, camelCase fields. One class per file.
• using groups: System / UnityEngine / third-party / project — blank-line separated.
• [Header("...")] groups in the Inspector.
• No magic numbers — extract to a serialized field or const.
• Coroutines need using System.Collections; (IEnumerator, non-generic).
• Event subscriptions in Awake()/OnEnable() get mirrored unsubscriptions in OnDestroy()/OnDisable().
• Network calls (Phase 4): coroutine + UnityWebRequest, never blocking the main thread.

After creating

Remind the user: a script does nothing until attached to a GameObject — and the scene must be saved (Ctrl+S) afterwards.
