Component Catalog

Every pipeline component shipped in force-app/main/default/classes/. Use this as the lookup when authoring pipeline JSON or building components in Studio. 75 types across 4 base classes.

AI nodes. LLM-backed

All extend BaseLLMNode. Inherit shared LLM stage config keys. Differ in default Component_Type__c lookup, prompt shape, and output validation.

Type	Role	Config
LLMChat	Single-turn chat completion. Generic.	messages (alternative to prompt)
LLMGenerator	Free-form generation. Looser defaults than LLMChat.	—
LLMSummarizer	Summarisation. Defaults `summarizeMaxTokens` (400) + `summarizeTemperature` (0.3).	maxTokens, style
LLMClassifier	Pick one label from a closed enum.	outputSchema.enum
LLMExtractor	Extract structured fields from unstructured text.	outputSchema.properties
LLMRewriter	Rewrite text per style instruction.	style, tone
LLMTranslator	Translate text to target locale.	targetLanguage
LLMValidator	Pass/fail evaluation against a rubric.	rubric
LLMCritic	Multi-criterion scoring. Surfaces `__meta.scores`.	criteria[]
LLMQuestionAnswer	RAG-style Q&A. Pairs with a retrieval stage.	context placeholder
LLMAnalyzer	Multi-axis analysis (sentiment + intent + entities).	axes[]
LLMImprover	Self-improvement loop on a draft.	iterations, criteria
LLMSelector	Pick best of N candidates.	candidates
LLMEmbedder	Returns vector embedding for text.	model must have IsEmbedding__c = true
ComplianceEvaluator	Specialised LLMValidator pinned to a compliance prompt.	policyKey

AI nodes. Non-LLM

Type	Role	Provider interface
AudioTranscriber	Speech-to-text	AudioProvider.AudioTranscriber
TextToSpeech	Text-to-speech	AudioProvider.TextToSpeech
DocumentReader	OCR + layout extraction	DocumentProvider.DocumentReader
FormExtractor	Structured form extraction (key-value)	DocumentProvider.FormExtractor
KnowledgeQuery	Search a Knowledge index	VectorDBProvider.KnowledgeQuery
RAGRetriever	Vector retrieval for RAG	VectorDBProvider.RAGRetriever

Operators. Data transform + IO

All extend BaseOperator. Pure functions of context unless flagged otherwise.

Type	Role
SoqlQuery	Run SOQL under user mode. FLS-honoured.
DmlOperation	Insert/update/delete records.
HttpCallout	Outbound HTTP via Named Credential. URL allowlist enforced.
EmailSender	Messaging.SingleEmailMessage send.
Logger	Emit FMLog line. Honours enableVerboseDebugLogs gate.
TemplateRenderer	Render Visualforce / string template.
DataMapper	Map fields between two SObject shapes.
JsonTransformOperator	JSONPath-style transform.
Filter	Predicate filter on a list.
Aggregate	count / sum / avg / min / max / group_by on a list.
MergeData	Merge records by key.
Split	Partition input into branches by predicate.
OutputRouter	Route to one of N named outputs by predicate.
CombinerNode	Concatenate/zip stage outputs.
VariableSet	Write to context.variables.
PipelineOutput	Set the pipeline's terminal output.
Validate	Schema-validate input; throws on failure.
Guard	Predicate gate. Skips downstream stages on failure.
RuleChecker	Evaluate one or more declarative rules.
PolicyLookup	Resolve a policy from FM_Pii_Policy__mdt or similar.
RateLimiter	Per-key rolling rate cap.
DelayOperator	Sleep N ms (sync) or yield (async).
CacheOperator	LRU lookup against local.FMLLMCache.
FileParser	Parse CSV/JSON/XML attachment.
InvocableApex	Call any @InvocableMethod. Bridge for legacy code.
WebhookWaiterAsync	Block on inbound webhook. Async via FM_Signal__c.

Flow control. Branch, loop, recover, fan-out

All extend BaseFlowControl. These steer the executor; many cause the runner to yield, fan-out, or push a sub-frame.

Type	Role
ConditionalFlowControl	if / else branch on expression.
Router	Multi-way dispatch by stage-id mapping.
SwitchRouter	switch on expression; cases → branches.
ForEach	Iterate a list. Optional parallel fan-out via parallelism. Cap forEachMaxItems (500).
LoopExecutor	Generic while-loop with break/continue.
BreakLoop	Exits nearest ForEach / LoopExecutor.
ContinueLoop	Skips to next iteration.
ReturnEarly	Terminates pipeline with current output as result.
TryCatch	Catches downstream errors; finally always runs.
RetryHandler	Exponential-backoff retry around a sub-tree.
CircuitBreaker	Fail-fast / buffered modes. Buffered writes to FM_Circuit_Queue__c.
TimeoutHandler	Wall-clock timeout around a sub-tree.
ParallelExecutor	Async fan-out across N branches. Joins via ExecutionState.asyncTokens.
WaitForSignal	Suspend until FM_Signal__c row matches.
SubPipeline	Recursive pipeline call. Inputs resolved like a normal stage.

Org Chat private components

Five components only used inside the org_chat_phase_1 pipeline. Not in the Studio palette.

• OrgChatDecompose — planner LLM step (REL-3 enriched with relationship hints)
• OrgChatPickObject — pick the target SObject from the user query + allowlist
• OrgChatBuildSoql — build SOQL using FMSchemaCatalog.toPromptTextWithRels
• OrgChatGuardSoql — validate SOQL via FMSoqlValidator (REL-2 child-subquery aware)
• OrgChatShapeResponse — shape rows + summary for the LWC turn

Adding a new component

1. Subclass BaseNode, BaseOperator, or BaseFlowControl (or BaseLLMNode for LLM stages).
2. Implement executeImpl(context, config) (or executeAsync for async-capable operators).
3. Register the type string in FM_Component_Type__mdt.
4. Add a Studio palette descriptor in Flow_Node_Type__mdt.
5. Write <YourClass>_Test.cls covering happy path + at least one error path.
