Describe the problem that you experienced

The agent skill for Signal Forms states that null should never be used for numbers , and instead enforces initializing with defaults 0 for numbers.

However, in recent Angular versions, null is permitted for optional number fields. The skill is misleading and prevents users from modeling optional/nullable fields correctly. As the possibility to use null has been introduced in the 21.2.x version it should encourage the usage of null for input number that have an empty value.

The skill should:

• Clearly state when and where null can be used for any field, especially numbers and optionals.
• Provide examples for both required and optional model initialization.
• Remove or update warnings/callouts forbidding null in all cases.
• Help users confidently create models that fit their needs.
