• src/tools/localTools/projectHints.ts:119-302 (handler)

  Main execution handler for the 'local_project_hints' tool. Validates inputs, generates project or folder hints using ProjectHintsGenerator, supports multiple formats (compact, structured, json, markdown, html), analyzes file composition, and returns formatted hints with metadata.
  export async function handleProjectHints(args: any): Promise<any> { const { projectPath, format = 'compact', maxFiles = 100, folderPath, includeContent = false, useAI = true, maxFileSizeForSymbols = 50000, query, } = args; // Validate that projectPath is provided and is absolute if (!projectPath) { throw new Error( '❌ projectPath is required. Please provide an absolute path to the project directory.' ); } const resolvedProjectPath = validateAndResolvePath(projectPath); logger.info('📊 Generating project hints', { originalPath: projectPath, resolvedPath: resolvedProjectPath, format, maxFiles, folderPath, }); try { const hintsGenerator = new ProjectHintsGenerator(); if (folderPath && folderPath !== '.') { // Folder-specific analysis const folderHints = await hintsGenerator.generateFolderDocumentation( resolvedProjectPath, folderPath, { useAI, maxDepth: 2, includeSubfolders: true, } ); return { success: true, hints: formatFolderHints(folderHints, format), type: 'folder-specific', metadata: { folderPath, keyFiles: folderHints.keyFiles.length, subFolders: folderHints.subFolders.length, confidence: folderHints.confidence, }, }; } else { // Use the core ProjectHintsGenerator which handles embedding-assisted features logger.info('📊 Generating project hints with core generator', { format, maxFiles, useEmbeddingAssisted: hintsGenerator['shouldUseEmbeddingAssistedHints']?.(), }); const hintsResult = await hintsGenerator.generateProjectHints(resolvedProjectPath, { maxFiles, includeContent, useAI, maxFileSizeForSymbols, format: 'json', // Get raw hints object for processing }); // Type guard to ensure we have the ProjectHints object const hints = hintsResult as ProjectHints; // Handle different output formats let formattedHints: string; logger.info('🎨 Formatting hints', { requestedFormat: format }); if (format === 'html') { // Regenerate with the desired format using the generator's built-in formatting logger.info('🔄 Regenerating with built-in HTML formatting'); formattedHints = (await hintsGenerator.generateProjectHints(resolvedProjectPath, { maxFiles, includeContent, useAI, maxFileSizeForSymbols, format, })) as string; logger.info('✅ Generated formatted hints', { format, length: formattedHints.length, preview: formattedHints.substring(0, 100) + '...', }); } else if (format === 'structured') { // Use enhanced structured format that includes embedding-assisted features logger.info('🔧 Using structured format with potential embedding enhancement'); const fileDiscovery = new FileDiscovery(resolvedProjectPath, { maxFileSize: maxFileSizeForSymbols, }); const allFiles = await fileDiscovery.discoverFiles(); const limitedFiles = fileDiscovery.sortByRelevance(allFiles).slice(0, maxFiles); // Analyze file composition across the project const fileCompositionStructured = analyzeFileComposition(allFiles, limitedFiles); const enhancedSummary = await buildEnhancedProjectSummary( resolvedProjectPath, limitedFiles, query ); // Add answer draft if query provided if (query) { const answerDraft = generateAnswerDraft(enhancedSummary, query); if (answerDraft) { (enhancedSummary as any).answerDraft = answerDraft; } } formattedHints = formatProjectHints(enhancedSummary, format); return { success: true, hints: formattedHints, type: 'enhanced-project-wide', metadata: { filesAnalyzed: enhancedSummary.summary.files, capabilities: enhancedSummary.capabilities.domains, hintsCount: enhancedSummary.hints.length, riskScore: enhancedSummary.risks.score, nextMode: enhancedSummary.next.mode, hasQuery: !!query, enhanced: true, embeddingAssisted: hintsGenerator['shouldUseEmbeddingAssistedHints']?.() || false, fileComposition: fileCompositionStructured, }, }; } else { // Use local formatting for remaining cases logger.info('📝 Using local formatting for', { format }); formattedHints = formatProjectHints(hints, format); } // Analyze file composition for metadata const fileDiscoveryForComposition = new FileDiscovery(resolvedProjectPath, { maxFileSize: maxFileSizeForSymbols, }); const allFilesForComposition = await fileDiscoveryForComposition.discoverFiles(); const limitedFilesForComposition = fileDiscoveryForComposition .sortByRelevance(allFilesForComposition) .slice(0, maxFiles); const fileComposition = analyzeFileComposition( allFilesForComposition, limitedFilesForComposition ); return { success: true, hints: formattedHints, type: 'project-wide', metadata: { filesAnalyzed: hints.totalFiles, foldersFound: Object.keys(hints.folderHints).length, primaryLanguages: hints.primaryLanguages, architecturePatterns: hints.architectureKeywords, topFunctions: hints.symbolHints.functions.slice(0, 10).map((f: any) => f.word), codebaseSize: hints.codebaseSize, enhanced: false, embeddingAssisted: hintsGenerator['shouldUseEmbeddingAssistedHints']?.() || false, fileComposition, }, }; } } catch (error) { logger.error('❌ Project hints generation failed', { error: error instanceof Error ? error.message : String(error), }); return { success: false, error: error instanceof Error ? error.message : String(error), fallback: `Could not analyze project structure for ${projectPath}.

• src/tools/localTools/index.ts:129-137 (registration)

  Module-level registration of the 'local_project_hints' handler in the localHandlers object, which is imported and used by higher-level tool registries.
  export const localHandlers = { ...(allowLocalContext ? { local_context: handleSemanticCompact } : {}), local_project_hints: handleProjectHints, local_file_summary: handleFileSummary, frontend_insights: handleFrontendInsights, local_debug_context: handleLocalDebugContext, manage_embeddings: handleManageEmbeddings, ast_grep_search: handleAstGrep, };
• src/index.ts:135-142 (registration)

  Primary MCP server registration of the 'local_project_hints' handler in the AmbianceMCPServer instance's handlers object, used for tool execution requests.
  this.handlers = { ...(allowLocalContext ? { local_context: handleSemanticCompact } : {}), local_project_hints: handleProjectHints, local_file_summary: handleFileSummary, frontend_insights: handleFrontendInsights, local_debug_context: handleLocalDebugContext, ast_grep_search: handleAstGrep, };
• src/tools/localTools/projectHints.ts:26-59 (helper)

  Helper function used by the handler to analyze file composition by type (extensions), providing metadata on total files, analyzed files, and filtered out files.
  function analyzeFileComposition( allFiles: FileInfo[], analyzedFiles: FileInfo[] ): { totalFiles: number; byType: Record<string, number>; analyzedFiles: number; filteredOut: Record<string, number>; } { const byType: Record<string, number> = {}; const filteredOut: Record<string, number> = {}; // Count all files by extension for (const file of allFiles) { const ext = file.ext || path.extname(file.relPath).toLowerCase() || 'no-extension'; byType[ext] = (byType[ext] || 0) + 1; } // Count filtered out files (not in analyzedFiles) const analyzedFileSet = new Set(analyzedFiles.map(f => f.absPath)); for (const file of allFiles) { if (!analyzedFileSet.has(file.absPath)) { const ext = file.ext || path.extname(file.relPath).toLowerCase() || 'no-extension'; filteredOut[ext] = (filteredOut[ext] || 0) + 1; } } return { totalFiles: allFiles.length, byType, analyzedFiles: analyzedFiles.length, filteredOut, }; }
