Salesforce Spring '26: The Dawn of the Agentic Enterprise

The Salesforce Spring '26 release represents a seismic shift in the ecosystem, moving from assistive AI Copilots to autonomous Agentforce agents. This release is a technical "gobstopper," packed with features that redefine how we build on the platform.

From the rebranding of Data Cloud to Data 360 to the introduction of Agent Script, we are witnessing the birth of the Agentic Enterprise.

1. Predictable Autonomy with Agent Script (Beta)

While LLMs are powerful due to their variability, enterprise software demands predictability. Agent Script is a new, declarative YAML-like language designed to provide strict structure to agents.

Why it matters:

It allows you to define "guardrails" using a series of blocks (System, Variables, Language, Topics) that dictate how an agent reasons and which actions it can take.

Agent Script Example (my_agent.agent):

Copy
1system:
2  instructions: |
3    You are a professional support agent. 
4    Always verify the customer's identity before sharing order details.
5variables:
6  customer_status: "Guest"
7language:
8  default: "en-US"
9topics:
10  - name: "Order Support"
11    description: "Handles questions about order status and tracking."
12    instructions: "If customer provides an Order ID, call the 'GetOrderStatus' action."
13    actions:
14      - "GetOrderStatus"

2. High-Performance Data: Named Query API (GA)

The Named Query API is now Generally Available, offering a high-performance alternative to traditional data retrieval methods. It allows you to define and expose custom SOQL queries as scalable REST actions.

Syntax & Usage

When you create a Named Query API, it is accessible via a simple GET request. Parameters are passed as URI query parameters.

Endpoint Syntax: GET /services/data/v66.0/named/query/NQ_API_NAME?param_name=param_value

Supported Parameter Types

The API supports a wide range of literal types for parameters, ensuring flexibility across different data models:

• String: name=Acme
• Date/Datetime: closedate=2025-10-14 or date=2025-10-14T09:00:00-07:00
• Date Formulas: createddate=TODAY or LAST_N_DAYS:10
• Numeric: quantity=36 or amount=10.99
• Boolean: doNotCall=false
• Multi-Currency: amount=USD20000

Real-World Example

Suppose you have a Named Query named Get_Account_Details_FromName. Here is how you would invoke it and what you can expect in return.

Example Request: /services/data/v66.0/named/query/Get_Account_Details_From_Name?name=Acme

Example Response Body:

Copy
1{
2    "totalSize": 1,
3    "done": true,
4    "records": [
5        {
6            "attributes": {
7                "type": "Account",
8                "url": "/services/data/v66.0/sobjects/Account/001Ws00003cPDMRIA4"
9            },
10            "Name": "Acme",
11            "Description": "A trendy dining group...",
12            "Phone": "214-555-1010",
13            "Website": "www.urbaneats.com",
14            "BillingAddress": {
15                "city": "Dallas",
16                "state": "TX"
17            }
18        }
19    ]
20}

3. Mastering Large Datasets: Apex Cursors (GA)

Managing large SOQL results in asynchronous Apex just got easier. The Cursor Class allows you to store a query in the server cache and access it in precise chunks.

• Scale: Up to 50 million records.
• Consistency: The PaginationCursor class ensures that page sizes remain consistent even if records are deleted between fetches.

Apex Cursor Example:

Copy
1// Create a cursor for 1M+ records
2Database.Cursor myCursor = Database.getCursor('SELECT Id, Name FROM Large_Object__c');
3
4// Fetch first 200 records
5List<Large_Object__c> firstChunk = myCursor.fetch(0, 200);
6
7// Fetch next 200 records from a different position
8List<Large_Object__c> nextChunk = myCursor.fetch(200, 200);

4. Smarter Deployments: RunRelevantTests (Beta)

Tired of waiting for 1,000 unit tests to run for a one-line change? RunRelevantTests uses dependency graphs to discover and execute only the tests connected to your payload.

You can now explicitly link tests to classes using the testFor parameter in the @isTest annotation:

Copy
1@isTest(testFor='OrderController')
2public class OrderControllerTest {
3    @isTest(critical=true) // Mark as critical to always run
4    static void testOrderCreation() {
5        // Test logic
6    }
7}

5. LWC Innovations: GraphQL Mutations & Complex Logic

The boundary between server-side and client-side logic continues to blur with major LWC updates.

GraphQL Mutations

We now have full imperative support for creation, updates, and deletions via the executeMutation adapter.

LWC GraphQL Mutation Example:

Copy
1import { gql, executeMutation } from 'lightning/graphql';
2
3const CREATE_ACCOUNT = gql`
4  mutation CreateAcc($input: AccountCreateInput!) {
5    uiapi {
6      AccountCreate(input: $input) {
7        Record { Id, Name { value } }
8      }
9    }
10  }
11`;
12
13// Imperative call
14const result = await executeMutation({
15    query: CREATE_ACCOUNT,
16    variables: { input: { Account: { Name: 'Tirnav Solutions' } } }
17});

Complex Template Expressions (Beta)

You can finally write inline JavaScript logic in your HTML templates, drastically reducing boilerplate getters.

Copy
1<!-- Complex Expressions in LWC -->
2<template>
3    <p>{isPremium ? '💎 Premium Member' : 'Standard User'}</p>
4    <p>Total: {items.filter(i => i.active).length}</p>
5</template>

6. Security Enforcement: No More Session IDs

In a move to harden the platform, Salesforce will no longer send Session IDs with Outbound Messages starting February 16, 2026.

The fix: If you depend on two-way integrations via Outbound Messages, you must migrate to Flow-based approvals or use External Client Apps with OAuth for authentication.
