All notable changes to this project will be documented in this file.

2025-08-20

Major: Enhanced Indexing System - Function-Level Intelligence

  • Function-Level Chunking: GDScript files now parsed semantically - each func, signal, and @export becomes a separate searchable unit with rich metadata instead of basic line-based chunks
  • Signal Flow Tracking: Complete understanding of signal emission → connection → handler chains across entire projects
  • Multi-Hop Dependency Tracing: Trace function call chains across files (e.g., Input → Controller → Physics → Animation) with configurable depth
  • Enhanced Search Modes:
    • Semantic search (AI understanding of code intent)
    • Keyword search (exact text matching with proper BM25 implementation)
    • Hybrid search (combines both approaches)
  • Smart Search Intelligence: Auto-detection of search intent, cross-section deduplication, exact match verification
  • Graph Centrality Analysis: Identify architecturally important files and their structural roles in projects
  • Performance Improvements: ~2.7x more intelligent chunks from same files (51 → 138 chunks in demo project)

Backend: Migration to Weaviate Vector Database

  • Migrated from BigQuery to Weaviate: Enhanced performance and better vector search capabilities
  • Three Collection Architecture:
    • ProjectEmbedding: Function-level chunks with dependency metadata
    • ProjectGraph: File-to-file relationships
    • ProjectDependencies: Function-to-function dependency mapping
  • Real-Time Updates: All collections updated automatically when files change, including dependency re-extraction
  • Advanced Filtering: Eliminates indexing of .import files and other binary assets
  • Weaviate v4 Compatibility: Updated client implementation with proper error handling and fallback strategies

Search & Dependencies

  • Dependency Types Tracked: Function calls, signal emissions, node access, physics API usage, input system access
  • Context-Aware Results: Search results include function metadata (signals emitted, functions called, nodes accessed)
  • Nuclear Filtering System: Multi-layer filtering prevents irrelevant results (.import files, etc.)
  • Exact Match Verification: Keyword search validates actual text presence in content
  • Enhanced Error Recovery: Graceful fallbacks when Weaviate BM25 API encounters issues

Documentation & Configuration

  • New Technical Documentation: Added comprehensive backend/indexing.md with architecture details, examples, and troubleshooting
  • Updated Backend README: Modernized backend/README.md to reflect Weaviate-based system with enhanced API documentation
  • Enhanced Main README: Added Advanced Indexing System section and backend documentation links throughout
  • Environment Configuration: Updated setup instructions for Weaviate requirements (WEAVIATE_URL, WEAVIATE_API_KEY)

API Enhancements

  • Enhanced /search_across_project endpoint: Added trace_dependencies, search_mode parameters
  • Improved Response Structure: Results now include chunk_type, function_name, dependencies, signals_emitted metadata
  • Debug Logging: Comprehensive logging for function extraction, dependency tracking, and search execution
  • Performance Metrics: Detailed timing and chunk count reporting

2025-08-18

  • Tightened file management tools: apply-edit now outputs structured diff JSON instead of code (1e8ede8e55).
  • updates sprite and sprite sheets

2025-08-16

  • Apply-edit: create structured diffs; agent can view live and debugger errors (6626e21ec5).
  • Updated .gcloudignore (31cc62bd4d).
  • Indexing and search: improved graph creation and querying; integrated latest Godot docs indexing as a tool (dd05c8b4e5).

2025-08-15

  • Misc: updated contact email (17ee1973c0).
  • Apply-edit: ability to apply patches at specific file locations (390e3b530f).
  • Apply-edit: text updates (7830f90f2e).
  • README: added Discord link (d2d77e92ca); typo fix; general updates (b91198bcd6, d88c5f0296).
  • Editor: script editor whitespace cleanup (de0a870f6e).

2025-08-14

  • Initial import (clean history; removed sensitive data) (abab192012).
