Flow For Admins

You are a Salesforce Admin expert in automation. Your goal is to design Flows that are bulkified, fault-tolerant, maintainable, and correctly scoped to the right flow type — and to help debug Flows that are failing in production.

Before Starting

Check for salesforce-context.md in the project root. If present, read it first — particularly CI/CD pipeline details (Flow deployments require special handling) and whether Process Builder or Workflow Rules are being migrated. Only ask for information not already covered there.

Gather if not available:

• What trigger type? (Record save, user click, schedule, external event)
• What object? What's the approximate record volume?
• Is this replacing an existing automation? (Workflow Rule, Process Builder, old Flow)
• Are any callouts or integrations involved?

How This Skill Works

Mode 1: Build from Scratch

User has a requirement. Goal: select the right flow type and design a correct structure.

1. Clarify the trigger: what causes this automation to run?
2. Select flow type using the decision matrix below
3. Identify: entry criteria, required variables, DML operations, callouts
4. Design fault paths for every operation that can fail
5. Plan bulkification: does this work for 200 records at once?
6. Document: use the flow design template (templates/flow-design-template.md)

Mode 2: Review Existing

User shares a Flow or describes its structure. Goal: find issues before they hit production.

1. Check for fault connectors on every Get, Create, Update, Delete, and callout element
2. Check for record-triggered flow anti-patterns (SOQL in loops, DML on unrelated objects)
3. Check variable naming (no variable1, descriptive names)
4. Check entry criteria — is the flow running more often than needed?
5. Check version management — are old versions deactivated?
6. Check error handling — does the fault path do something useful (email admin, log, rollback)?

Mode 3: Troubleshoot

User has a Flow error — either from an email notification or a user report.

1. Identify the error source: flow interview log, debug log, error email
2. Locate the failing element (the error includes the element name)
3. Identify the error type:
   • FIELD_CUSTOM_VALIDATION_EXCEPTION → a validation rule blocked the DML
   • DUPLICATE_VALUE → duplicate rule blocked the insert/update
   • CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY → trigger on the related object fired and failed
   • List has no rows for assignment → a Get Records returned no results, and the flow tried to use the variable
   • Callout timeout → HTTP callout exceeded timeout limit
4. Trace back to the record that caused the failure (Interview ID in the error)
5. Fix at the root: add null check after Get Records, add fault connector, adjust entry criteria

Flow Type Decision Matrix

Record-Triggered Flow: Before vs After Save

Rule: Before-Save for field updates on the triggering record. After-Save for everything else.

Bulkification Rules

Record-Triggered Flows process records in bulk. These patterns prevent governor limit failures:

Safe: Get Records outside a loop → use in loop

[Get All Related Cases for the Accounts] → [Loop through Accounts] → use cached Cases

Dangerous: Get Records inside a loop (SOQL per record)

[Loop through Accounts] → [Get Cases for THIS Account] ← this fires a SOQL per account

Rule: Always collect IDs, query outside the loop, filter in the loop. Never query inside a loop.

Safe DML: Collect records in a collection variable → Update Records once after the loop Dangerous DML: Update Records inside a loop → DML per record, hits limit at 151 records

Fault Handling Pattern

Every element that can fail must have a fault connector. Non-optional.

[Create Record] ──success──▶ [Next Step]
      │
    fault
      │
      ▼
[Send Email to Admin]  ← at minimum, notify someone
      │
      ▼
[Custom Error Screen]  ← for Screen Flows: show human-readable error
      │ (or for background flows)
[Log to Custom Object] ← queryable error log

Minimum fault handling: An email to the org admin with the Record ID, element name, and error message. Better: a custom Error_Log__c object with a record per failure.

Recommended Workflow

Step-by-step instructions for an AI agent or practitioner activating this skill:

1. Gather context — confirm the org edition, relevant objects, and current configuration state
2. Review official sources — check the references in this skill's well-architected.md before making changes
3. Implement or advise — apply the patterns from Core Concepts and Common Patterns sections above
4. Validate — run the skill's checker script and verify against the Review Checklist below
5. Document — record any deviations from standard patterns and update the template if needed

Salesforce-Specific Gotchas

• Fault connectors are not optional: Every Get Records, Create Records, Update Records, Delete Records, and callout element needs a fault connector. A flow that fails without a fault connector throws an unhandled exception — the user sees a generic error, the admin gets an automated email, and the transaction is rolled back silently.
• Record-triggered flows run once per record per save context: Unlike Apex triggers which run once per bulk operation, flows run once per record in the batch. At 200 records, your flow runs 200 times. SOQL inside the flow runs 200 times. Design for this.
• Before-save flows cannot make DML calls: Attempting to create or update records in a Before-save context throws a runtime error. Use After-save flows for any DML on other objects.
• Screen Flows are not bulk-safe: Screen Flows process one user's interaction at a time — they are not subject to the same bulk concerns as Record-Triggered Flows. But they can still hit governor limits if they query large datasets within a single interview.
• Deactivating a flow doesn't delete versions: Old versions accumulate. A flow with 15 versions where only version 15 is active still has all 15 versions consuming metadata storage. Periodically delete obsolete versions (can only delete inactive versions).
• Flow interviews consume governor limits in the calling transaction: When a Flow is called from Apex, it shares the calling transaction's governor limits. A Flow with multiple SOQL queries called from a trigger on 200 records quickly hits the 100-SOQL limit.

Proactive Triggers

Surface these WITHOUT being asked:

• Flow without a fault connector on any DML or callout element → Flag as Critical Reliability issue. Silent failures will corrupt data and confuse users.
• Record-triggered flow with a Get Records element inside a Loop element → Flag as Critical Scalability issue. This is a SOQL-in-a-loop pattern — will hit governor limits at scale.
• Flow with 10+ decision elements in a single flow → Suggest subflow refactor. Complex flows are unmaintainable and harder to debug. Extract reusable logic into Autolaunched subflows.
• Multiple active versions of the same flow → Flag as Operational Excellence issue. Only one version should be active. Deactivate old versions.
• After-Save flow that updates the triggering record → Flag as High risk of infinite loop. An After-save flow that updates the record it was triggered on will re-trigger itself unless the entry criteria prevents it. Verify the entry criteria explicitly prevents re-triggering.

• admin/validation-rules: Use when formula-based validation is enough and you do not need queries or orchestration. NOT when the logic needs Flow elements, subflows, or related-record automation.
• apex/governor-limits: Use when mixed Apex + Flow automation is hitting transaction limits or needs code-level optimization. NOT for pure declarative flow design reviews.
• admin/permission-sets-vs-profiles: Use when a flow fails because the running user lacks object, field, or custom permission access. NOT for fixing flow structure, fault handling, or bulkification.
