Sf Flow

sf-flow: Salesforce Flow Creation and Validation

Expert Salesforce Flow Builder with deep knowledge of best practices, bulkification, and Winter '26 (API 65.0) metadata. Create production-ready, performant, secure, and maintainable flows.

📋 Quick Reference: Validation Script

Validate Flow XML before deployment:

# Path to validation script
python3 ~/.claude/plugins/marketplaces/sf-skills/sf-flow-builder/hooks/scripts/validate_flow.py <flow-file.xml>

# Example
python3 ~/.claude/plugins/marketplaces/sf-skills/sf-flow-builder/hooks/scripts/validate_flow.py \
  force-app/main/default/flows/Auto_Lead_Assignment.flow-meta.xml

Scoring: 110 points across 6 categories. Minimum 88 (80%) for deployment.

Core Responsibilities

1. Flow Generation: Create well-structured Flow metadata XML from requirements
2. Strict Validation: Enforce best practices with comprehensive checks and scoring
3. Safe Deployment: Integrate with sf-deploy skill for two-step validation and deployment
4. Testing Guidance: Provide type-specific testing checklists and verification steps

⚠️ CRITICAL: Orchestration Order

sf-metadata → sf-flow → sf-deploy → sf-data (you are here: sf-flow)

⚠️ Flow references custom object/fields? Create with sf-metadata FIRST. Deploy objects BEFORE flows.

1. sf-metadata  → Create objects/fields (local)
2. sf-flow      ◀── YOU ARE HERE (create flow locally)
3. sf-deploy    → Deploy all metadata (remote)
4. sf-data      → Create test data (remote - objects must exist!)

See docs/orchestration.md for extended orchestration patterns including Agentforce.

🔑 Key Insights

Workflow Design (5-Phase Pattern)

Phase 1: Requirements Gathering

Before building, evaluate alternatives: See docs/flow-best-practices.md Section 1 "When NOT to Use Flow" - sometimes a Formula Field, Validation Rule, or Roll-Up Summary Field is the better choice.

Use AskUserQuestion to gather:

• Flow type (Screen, Record-Triggered After/Before Save/Delete, Platform Event, Autolaunched, Scheduled)
• Primary purpose (one sentence)
• Trigger object/conditions (if record-triggered)
• Target org alias

Pre-Development Planning: For complex flows, document requirements and sketch logic before building. See docs/flow-best-practices.md Section 2 "Pre-Development Planning" for templates and recommended tools.

Then:

1. Check existing flows: Glob: pattern="**/*.flow-meta.xml"
2. Offer reusable subflows: Sub_LogError, Sub_SendEmailAlert, Sub_ValidateRecord, Sub_UpdateRelatedRecords, Sub_QueryRecordsWithRetry → See docs/subflow-library.md (in sf-flow folder)
3. If complex automation: Reference docs/governance-checklist.md (in sf-flow folder)
4. Create TodoWrite tasks: Gather requirements ✓, Select template, Generate XML, Validate, Deploy, Test

Phase 2: Flow Design & Template Selection

Select template:

Element Pattern Templates (templates/elements/):

Template Path Resolution (try in order):

1. Marketplace folder: ~/.claude/plugins/marketplaces/sf-skills/sf-flow/templates/[template].xml
2. Project folder: [project-root]/sf-flow/templates/[template].xml

Example: Read: ~/.claude/plugins/marketplaces/sf-skills/sf-flow/templates/record-triggered-flow-template.xml

Naming Convention (Recommended Prefixes):

Format: [Prefix]_Object_Action using PascalCase (e.g., Auto_Lead_Priority_Assignment)

Screen Flow Button Config (CRITICAL):

Rule: allowFinish="true" required on all screens. Connector present → "Next", absent → "Finish".

Orchestration: For complex flows (multiple objects/steps), suggest Parent-Child or Sequential pattern.

• CRITICAL: Record-triggered flows CANNOT call subflows via XML deployment. Use inline orchestration instead. See docs/xml-gotchas.md (in sf-flow) and docs/orchestration-guide.md (in sf-flow)

Phase 3: Flow Generation & Validation

Create flow file:

mkdir -p force-app/main/default/flows
Write: force-app/main/default/flows/[FlowName].flow-meta.xml

Populate template: Replace placeholders, API Version: 65.0

CRITICAL Requirements:

• Alphabetical XML element ordering at root level
• NO <bulkSupport> (removed API 60.0+)
• Auto-Layout: all locationX/Y = 0
• Fault paths on all DML operations

Run Enhanced Validation (automatic via plugin hooks): The plugin automatically validates Flow XML files when written. Manual validation:

python3 ${CLAUDE_PLUGIN_ROOT}/hooks/scripts/validate_flow.py force-app/main/default/flows/[FlowName].flow-meta.xml

Validation (STRICT MODE):

• BLOCK: XML invalid, missing required fields (apiVersion/label/processType/status), API <65.0, broken refs, DML in loops
• WARN: Element ordering, deprecated elements, non-zero coords, missing fault paths, unused vars, naming violations

New v2.0.0 Validations:

• storeOutputAutomatically detection (data leak prevention)
• Same-object query anti-pattern (recommends $Record usage)
• Complex formula in loops warning
• Missing filters on Get Records
• Null check after Get Records recommendation
• Variable naming prefix validation (var_, col_, rec_, inp_, out_)

Run Simulation (REQUIRED for record-triggered/scheduled):

python3 ${CLAUDE_PLUGIN_ROOT}/hooks/scripts/simulate_flow.py force-app/main/default/flows/[FlowName].flow-meta.xml --test-records 200

If simulation fails: STOP and fix before proceeding.

Validation Report Format (6-Category Scoring 0-110):

Score: 92/110 ⭐⭐⭐⭐ Very Good
├─ Design & Naming: 18/20 (90%)
├─ Logic & Structure: 20/20 (100%)
├─ Architecture: 12/15 (80%)
├─ Performance & Bulk Safety: 20/20 (100%)
├─ Error Handling: 15/20 (75%)
└─ Security: 15/15 (100%)

Strict Mode: If ANY errors/warnings → Block with options: (1) Apply auto-fixes, (2) Show manual fixes, (3) Generate corrected version. DO NOT PROCEED until 100% clean.

⛔ GENERATION GUARDRAILS (MANDATORY)

BEFORE generating ANY Flow XML, Claude MUST verify no anti-patterns are introduced.

If ANY of these patterns would be generated, STOP and ask the user:

"I noticed [pattern]. This will cause [problem]. Should I: A) Refactor to use [correct pattern] B) Proceed anyway (not recommended)"

DO NOT generate anti-patterns even if explicitly requested. Ask user to confirm the exception with documented justification.

Phase 4: Deployment & Integration

Pattern:

1. Skill(skill="sf-deploy", args="Deploy flow [path] to [org] with --dry-run")
2. Review validation results
3. Skill(skill="sf-deploy", args="Proceed with actual deployment")
4. Edit <status>Draft</status> → Active, redeploy

For Agentforce Flows: Variable names must match Agent Script input/output names exactly.

For complex flows: docs/governance-checklist.md (in sf-flow)

Phase 5: Testing & Documentation

Type-specific testing: See docs/testing-guide.md | docs/testing-checklist.md | docs/wait-patterns.md (Wait element guidance)

Quick reference:

• Screen: Setup → Flows → Run, test all paths/profiles
• Record-Triggered: Create record, verify Debug Logs, bulk test 200+ records
• Autolaunched: Apex test class, edge cases, bulkification
• Scheduled: Verify schedule, manual Run first, monitor logs

Best Practices: See docs/flow-best-practices.md (in sf-flow) for:

• Three-tier error handling strategy
• Multi-step DML rollback patterns
• Screen flow UX guidelines
• Bypass mechanism for data loads

Security: Test with multiple profiles. System mode requires security review.

Completion Summary:

✓ Flow Creation Complete: [FlowName]
  Type: [type] | API: 65.0 | Status: [Draft/Active]
  Location: force-app/main/default/flows/[FlowName].flow-meta.xml
  Validation: PASSED (Score: XX/110)

Best Practices (Built-In Enforcement)

⛔ CRITICAL: Record-Triggered Flow Architecture

NEVER loop over triggered records. $Record = single record; platform handles batching.

Loops for RELATED records only: Get Records → Loop collection → Assignment → DML after loop

⛔ CRITICAL: No Parent Traversal in Get Records

recordLookups cannot query Parent.Field (e.g., Manager.Name). Solution: Two Get Records - child first, then parent by Id.

recordLookups Best Practices

Critical Requirements

• API 65.0: Latest features
• No DML in Loops: Collect in loop → DML after loop (causes bulk failures otherwise)
• Bulkify: For RELATED records only - platform handles triggered record batching
• Fault Paths: All DML must have fault connectors
  • ⚠️ Fault connectors CANNOT self-reference - Error: "element cannot be connected to itself"
  • Route fault connectors to a DIFFERENT element (dedicated error handler)
• Auto-Layout: All locationX/Y = 0 (cleaner git diffs)
  • UI may show "Free-Form" dropdown, but locationX/Y = 0 IS Auto-Layout in XML
• No Parent Traversal: Use separate Get Records for relationship field data

XML Element Ordering (CRITICAL)

All elements of the same type MUST be grouped together. Do NOT scatter elements across the file.

Complete alphabetical order:

apiVersion → assignments → constants → decisions → description → environments →
formulas → interviewLabel → label → loops → processMetadataValues → processType →
recordCreates → recordDeletes → recordLookups → recordUpdates → runInMode →
screens → start → status → subflows → textTemplates → variables → waits

Common Mistake: Adding an assignment near related logic (e.g., after a loop) when other assignments exist earlier.

• Error: "Element assignments is duplicated at this location"
• Fix: Move ALL assignments to the assignments section

Performance

• Batch DML: Get Records → Assignment → Update Records pattern
• Filters over loops: Use Get Records with filters instead of loops + decisions
• Transform element: Powerful but complex XML - NOT recommended for hand-written flows

Design & Security

• Variable Names (v2.0.0): Use prefixes for clarity:
  • var_ Regular variables (e.g., var_AccountName)
  • col_ Collections (e.g., col_ContactIds)
  • rec_ Record variables (e.g., rec_Account)
  • inp_ Input variables (e.g., inp_RecordId)
  • out_ Output variables (e.g., out_IsSuccess)
• Element Names: PascalCase_With_Underscores (e.g., Check_Account_Type)
• Button Names (v2.0.0): Action_[Verb]_[Object] (e.g., Action_Save_Contact)
• System vs User Mode: Understand implications, validate FLS for sensitive fields
• No hardcoded data: Use variables/custom settings
• See docs/flow-best-practices.md (in sf-flow) for comprehensive guidance

Common Error Patterns

DML in Loop: Collect records in collection variable → Single DML after loop Missing Fault Path: Add fault connector from DML → error handling → log/display Self-Referencing Fault: Error "element cannot be connected to itself" → Route fault connector to DIFFERENT element Element Duplicated: Error "Element X is duplicated" → Group ALL elements of same type together Field Not Found: Verify field exists, deploy field first if missing Insufficient Permissions: Check profile permissions, consider System mode

XML Gotchas: See docs/xml-gotchas.md (in sf-flow)

Edge Cases

Debug: Flow not visible → deploy report + permissions | Tests fail → Debug Logs + bulk test | Sandbox→Prod fails → FLS + dependencies

⚠️ Flows for sf-ai-agentscript

When sf-ai-agentscript requests a Flow:

• sf-ai-agentscript will invoke sf-flow (this skill) to create Flows
• sf-flow creates the validated Flow XML
• sf-deploy handles deployment to org
• Action Definition registration required (see below)
• Only THEN can sf-ai-agentscript use flow://FlowName targets

Variable Name Matching: When creating Flows for Agentforce agents:

• Agent Script input/output names MUST match Flow variable API names exactly
• Use descriptive names (e.g., inp_AccountId, out_AccountName)
• Mismatched names cause "Internal Error" during agent publish

Output Variable Naming for Agentforce

Use out_ prefix for output variables to distinguish them in Action Definition schema:

<variables>
    <name>out_CaseSubject</name>
    <dataType>String</dataType>
    <isOutput>true</isOutput>
</variables>
<variables>
    <name>out_CaseStatus</name>
    <dataType>String</dataType>
    <isOutput>true</isOutput>
</variables>

Formula Expression Limitations in Flows

Flow formulas have more limited function support than formula fields. Avoid:

Action Definition Registration (REQUIRED)

CRITICAL: Creating a Flow is NOT sufficient for Agentforce. The Flow must be registered as an Action Definition.

Registration Workflow:

1. Deploy Flow to target org via sf-deploy
2. Navigate to Setup > Agentforce > Action Definitions
3. Click "New Action", select "Flow" as target type
4. Choose your deployed Flow from the list
5. Map input/output variables - these become the action's schema
6. Configure planner flags:
   • is_displayable: Can LLM show output to user?
   • is_used_by_planner: Can LLM use output for decisions?
7. Save the Action Definition

Flow Created  →  Deployed to Org  →  Action Definition Created  →  Agent Can Use
     ↑               ↑                        ↑                         ↑
   sf-flow       sf-deploy           Setup > Agentforce         @actions.MyAction

Why This Matters: The Action Definition is what exposes the Flow to the agent runtime with proper input/output schema mapping. Without it, @actions.FlowName will fail with ValidationError: Tool target 'FlowName' is not an action definition.
