Make wrong Salesforce logic look wrong

Teach them how to make wrong Salesforce logic stand out like a neon sign.

In Salesforce, we often do the opposite. We bury critical business logic deep inside nested Flow loops, mid-trigger actions, and invisible validation rules.

When a process breaks, it takes hours of log-diving to find out why.

The code isn't wrong; the architecture is wrong. But because it’s buried, it looks fine.

We need a Salesforce equivalent to Joel’s rule: The Gatekeeper Architecture.

Every Record-Triggered Flow, Apex Trigger, or Subflow must enforce a standard entry criterion right at the very top. Before you assign a single variable or execute a decision, you must validate three explicit criteria at the perimeter:

1. Early Country Validation: Is this automation supposed to run for this country?
2. Business Process Validation: Does this record state map to the active business lifecycle?
3. Actor Context Validation: Does the running user’s Profile or Custom Permission allow them to trigger this logic?

If it doesn't happen at the gate > Just stop

Imagine opening a Flow. Instead of a sprawling, 50-element spiderweb, the very first element is a decision box named: "Verify Context"

If that "Verify Context" isn't there, the Flow instantly looks wrong. A reviewer can spot the flaw in two seconds.

Joel emphasized that code reviews fail when you have to look in five different places to understand if a single line of code is safe. When you don’t validate Country, Process, and Persona at the absolute beginning, you force your team to reverse-engineer the entire platform just to debug one field update.

Bring the context to the very front. Make your wrong logic look wrong, so your right logic runs at twice the speed.
