27-27: Add documentation for the SUMMARY_LENGTH variable.Consider adding a comment to explain:
- The purpose of this variable
- The unit of measurement (characters/tokens)
- Any model-specific constraints
Example:
+# Maximum length of generated document summaries (in tokens) SUMMARY_LENGTH=10000src/callout.handlers/base.ts (1)

1-85: Consider enhancing document preparation for summarizationGiven that this PR focuses on document summarization, consider enhancing the document generation to include metadata that could aid in the summarization process:
- Add a timestamp to track document freshness
- Include document relationships (parent-child between callout and contributions)
- Add content type hints to help the summarization algorithm
Example metadata structure:
metadata: { documentId, source, type, title, timestamp: new Date().toISOString(), relationships: { parentId: callout.id, type: 'contribution' }, contentHints: { format: 'text/markdown', priority: contribution.priority } }This would help the summarization process:
- Prioritize recent content
- Understand document relationships
- Apply appropriate summarization strategies based on content type

73-79: Consider enhancing error handling for document summarization.Given that this PR implements document summarization functionality, the error handling could be more specific to distinguish between embedding and summarization failures.
Consider:
- Adding specific error codes for summarization failures
- Including summary-related metadata in error messages
- Structuring the error object to include both embedding and summarization status
Example enhancement:
export enum ErrorCode { VECTOR_INSERT = 'VECTOR_INSERT', SUMMARY_GENERATION = 'SUMMARY_GENERATION', SUMMARY_INTEGRATION = 'SUMMARY_INTEGRATION' } // Enhanced error structure interface IngestError { code?: ErrorCode; message: string; context?: { phase: 'embedding' | 'summarization'; documentCount?: number; failedDocuments?: string[]; }; }src/callout.handlers/link.collection.ts (1)
59-61: Consider if explicit loader types are necessary.While the type signature change is technically correct, it might be unnecessary since both
PDFLoaderandDocxLoaderextendBaseDocumentLoader. The current implementation doesn't use any loader-specific features that would require this explicit typing.src/summarize/body.of.knowledge.ts (1)
5-15: Refactor to avoid duplication of the 'system' messageThe 'system' message is identical in both
summarizePromptandrefinePrompt. Consider defining it once to reduce duplication.Here's how you can refactor the code:
+const systemMessage = [ + 'system', + `You are tasked with concising summaries sent by a user based entirely on the user input. While doing so + preserve as much information as possible like names, references titles, dates, etc.`, +]; const summarizePrompt = ChatPromptTemplate.fromMessages([ - [ - 'system', - `You are tasked with concising summaries sent by a user based entirely on the user input. While doing so - preserve as much information as possible like names, references titles, dates, etc.`, - ], + systemMessage, [ 'human', 'Write a detailed summary, no more than {summaryLength} characters of the following: {context}', ], ]); const refinePrompt = ChatPromptTemplate.fromMessages([ - [ - 'system', - `You are tasked with concising summaries sent by a user based entirely on the user input. While doing so - preserve as much information as possible like names, references titles, dates, etc.`, - ], + systemMessage, [ 'human', `Produce a final detailed summary, no more than {summaryLength} characters. Existing summary up to this point: {currentSummary} New context: {context} Given the new context, refine the original summary.`, ], ]);Also applies to: 16-33
src/summarize/document.ts (1)
6-6: Refine the comment for clarity and professionalismThe comment on line 6 reads:
// the system message is the same for both prompts but putting it into a variable and typing it is too hard...
Consider rephrasing or removing this comment to maintain a professional tone and clarity in the codebase.src/summarize/graph.ts (1)
58-64: Consider adding error handling for the state graph compilationWhile compiling the state graph, it's beneficial to include error handling to catch any issues during the graph construction.
const graph = new StateGraph(SummarizeAnnotation) .addNode('initialSummary', initialSummary) .addNode('refineSummary', refineSummary) .addEdge(START, 'initialSummary') .addConditionalEdges('initialSummary', shouldRefine, ['refineSummary', END]) .addConditionalEdges('refineSummary', shouldRefine, ['refineSummary', END]) - .compile(); + .compile() + .catch((error) => { + throw new Error(`Failed to compile the state graph: ${error.message}`); + });src/embed.ts (1)
105-105: Use actual space name instead of placeholderThe
titlefield is set to the placeholder'space name'. Replace it with the actual space name to ensure accurate metadata.Consider updating the code as follows:
- title: 'space name', + title: spaceID, // or use the actual space name if available

50-51: Verify the necessity of re-added GraphQL dependencies.The GraphQL-related packages that were previously removed have been re-added. Let's verify if these dependencies are still actively used in the codebase.
Also applies to: 55-55, 59-60
✅ Verification successful
Let me gather more specific information about GraphQL usage in the codebase.
I'm looking for evidence of active GraphQL usage in the codebase, including schema files, operations, generated types, and build scripts. This will help determine if these dependencies are actually needed or if they're remnants that can be safely removed.
Based on the comprehensive results, I can now generate the final response:
GraphQL dependencies are actively used and required
The GraphQL-related packages are actively used throughout the codebase as evidenced by:
- Multiple GraphQL schema files and fragments in the
graphql/directory- Active GraphQL client implementation in
src/graphql.client/AlkemioCliClient.ts- Generated types being used across multiple files (9 TypeScript files importing GraphQL operations/generated types)
- Codegen configuration (
codegen.yml) and npm script for code generation🏁 Scripts executed
The following scripts were executed for the analysis:

38-72: Consider integrating document summarization before embedding.Based on the PR objectives to "generate summaries for documents using LangGraph," consider adding a summarization step before the embedding process.
Let's verify if summarization is implemented elsewhere:
src/callout.handlers/link.collection.ts (1)
59-61: Review document chunking strategy for summarization.Given the PR's objective to maximize chunk sizes for better summarization, consider reviewing the document loading configuration. For example, the PDFLoader's
splitPages: falsesetting affects how content is chunked.Let's verify the current chunking configurations across loaders:
✅ Verification successful
Let me gather more information about the document loading and chunking configurations by checking other loaders and related code:
Based on the gathered information, I can now provide the final response:
Document chunking strategy appears to be consistently implemented
The codebase already implements a well-defined chunking strategy using
RecursiveCharacterTextSplitterwith explicitchunkSizeandchunkOverlapparameters insrc/embed.ts. The PDFLoader'ssplitPages: falseconfiguration insrc/callout.handlers/link.collection.tsaligns with this strategy by ensuring the PDF content is processed as a single document before being chunked by the text splitter.
- The chunking is centralized in
src/embed.tswhere documents from all loaders are processed uniformly- The PDFLoader's configuration complements this by preventing premature content splitting

61-77: Add error handling for document generationThe document generation process should handle potential errors gracefully.
Consider wrapping the document generation in a try-catch:

27-39: Consider adding return type annotation for better type safety.The function's return type can be explicitly annotated to improve type safety and documentation.
export const buildGraph = ( summarizePrompt: ChatPromptTemplate, refinePrompt: ChatPromptTemplate -) => { +): StateGraph<typeof SummarizeAnnotation> => {src/embed.ts (1)
21-25: Consider breaking down this function for better maintainability.While the type changes improve safety, this function has grown to handle multiple responsibilities:
- Document processing
- Summarization
- Embedding generation
- Database operations
Consider splitting this into smaller, focused functions:
async function processDocuments(docs: Document[], splitter: TextSplitter): Promise<ProcessedDocs>; async function generateSummaries(docs: ProcessedDocs): Promise<Summaries>; async function generateEmbeddings(docs: Summaries): Promise<Embeddings>; async function persistToDatabase(embeddings: Embeddings): Promise<boolean>;This would improve:
- Testability
- Maintainability
- Error handling
- Code reuse

🛠️ Refactor suggestion
Add validation and fix the 'source' typo.
- Fix the typo in metadata:
metadatas.push({
documentId: spaceID,
- soruce: space.profile.url,
+ source: space.profile.url,
type: 'bodyOfKnowledgeSummary',
title: space.profile?.displayName,
});- Add validation and error handling:
+ if (summaries.length === 0) {
+ logger.warn('No summaries generated, skipping body of knowledge generation');
+ return true;
+ }
const bokDescriptions = new Document({ pageContent: summaries.join('\n') });
const bokChunks = await splitter.splitDocuments([bokDescriptions]);
- const bokSummary = await summariseBodyOfKnowledge(bokChunks);
+ let bokSummary;
+ try {
+ bokSummary = await summariseBodyOfKnowledge(bokChunks);
+ if (!bokSummary) {
+ logger.error('Failed to generate body of knowledge summary');

104-109: Add validation for optional profile properties.While the metadata structure is correct, consider adding validation for optional profile properties:
metadatas.push({ documentId: spaceID, - source: space.profile.url, - type: 'bodyOfKnowledgeSummary', - title: space.profile?.displayName, + source: space.profile?.url ?? 'unknown', + type: 'bodyOfKnowledgeSummary', + title: space.profile?.displayName ?? 'Untitled Space', });

21-195: Consider breaking down the large function into smaller, focused components.The function currently handles multiple responsibilities:
- Document processing and summarization
- Embedding generation
- Collection management
- Data persistence
Consider splitting these into separate services or modules for better maintainability and testing:
- DocumentProcessingService
- EmbeddingService
- CollectionManagementService
This refactoring would:
- Improve testability
- Enhance maintainability
- Make the code more modular
- Allow for better error handling at each layer

Add validation and error handling for body of knowledge summary.
The current implementation needs additional safeguards:
+ if (summaries.length === 0) {
+ logger.warn('No summaries to process for body of knowledge');
+ return false;

🛠️ Refactor suggestion
Enhance error handling and logging in document processing.
While the summarization logic is well-structured, consider these improvements:
- Validate the generated summary
- Add logging for skipped documents
- Handle edge cases more gracefully
metadatas.push({ ...chunk.metadata, embeddingType: 'chunk', chunkIndex });
});
if (doc.pageContent.length > summaryLength) {
+ logger.debug(`Generating summary for document ${doc.metadata.documentId}`);
try {
const documentSummary = await summarizeDocument(splitted);
+ if (!documentSummary) {
+ logger.warn(`Failed to generate summary for ${doc.metadata.documentId}, using original content`);
+ summaries.push(doc.pageContent);
+ return;
+ }
ids.push(`${doc.metadata.documentId}-${doc.metadata.type}-summary`);
documents.push(documentSummary);
metadatas.push({ ...doc.metadata, embeddingType: 'summary' });
summaries.push(documentSummary);
} catch (err) {
logger.error(err);
+ logger.warn(`Error generating summary for ${doc.metadata.documentId}, using original content`);
+ summaries.push(doc.pageContent);
}
} else {
