Deploying Apex code to a Salesforce production environment has strict requirements to ensure stability and quality. Regardless of how the Apex is invoked, such as by an Agent Action, the deployment will fail unless two key conditions are met. First, the Apex classes and triggers in the deployment package must have a cumulative code coverage of at least 75%, and all triggers must have some coverage. Second, all dependent components that the Apex code references (e.g., custom objects, fields, other classes) must be included in the deployment package or already exist in the destination organization. These are fundamental platform-level prerequisites for any production deployment containing Apex.

B. The 75% code coverage is a mandatory check at the time of deployment to a production environment. The deployment itself will fail if this threshold is not met, regardless of the feature's activation status.

C. The Salesforce platform does not provide a mechanism to bypass the 75% code coverage requirement based on the code's intended use or invocation source. This rule applies universally to all Apex code deployed to production.

1. Salesforce Apex Developer Guide: Under the section "Deploying Apex to a Production Organization

" the guide states

"Before you can deploy your code to production

at least 75% of Apex code must be covered by unit tests... In addition

all triggers must have some test coverage." This confirms the 75% rule is a deployment prerequisite. (See Chapter: Deploying Apex).

2. Salesforce Metadata API Developer Guide: In the "Deploying Changes to a Salesforce Org" section

the documentation details the checkOnly deployment option. It explains that a test-level of RunLocalTests is the default for production deployments

which enforces the 75% code coverage requirement. (See Section: Deploying and Retrieving Metadata).

3. Salesforce Platform Developer I Certification Courseware (University-level equivalent): Modules on Apex testing and deployment consistently emphasize that all dependencies must be included in a change set or deployment package for the deployment to validate and succeed. A missing dependency will cause a deployment failure. (See Module: Apex Testing

Unit: Testing and Code Coverage).
