…ype checking - Simplify error handling from 12 to 3 layers (file-level, safeIterate, extractImports) - Enable type checking with lenient settings for better cross-file symbol resolution - Add detailed error tracking with phase detection and file paths - Remove excessive defensive coding while maintaining robustness - Improve error logging: first 10 errors at INFO level, rest at DEBUG - Better progress reporting with success/failure counts This improves callee extraction accuracy while maintaining graceful error handling.
…ncements Critical reliability fixes, performance improvements, and testability enhancements for Go support: ## High Priority Fixes - Fix silent dependency failures in copy-wasm.js script - Add runtime WASM validation to Go scanner with early error detection - Standardize error logging levels across scanners - Enhance progress feedback with time estimates ## Performance & Reliability - Add configurable concurrency via environment variables (DEV_AGENT_*_CONCURRENCY) - Implement system resource detection with intelligent defaults - Add batch processing for embeddings and file operations - Prevent memory issues on resource-constrained systems ## Architecture & Testability - Extract reusable utility modules for WASM resolution, concurrency, file validation - Implement dependency injection for mockable file system operations - Add comprehensive test coverage (57 new tests) for utility functions - Centralize error handling patterns across scanners ## Documentation - Add Configuration section to README with performance tuning - Create LANGUAGE_SUPPORT.md with contributor guidelines - Document new environment variables and troubleshooting steps - Add system requirements and optimization recommendations ## New Environment Variables - DEV_AGENT_TYPESCRIPT_CONCURRENCY: TypeScript scanner concurrency - DEV_AGENT_INDEXER_CONCURRENCY: Embedding batch concurrency - DEV_AGENT_GO_CONCURRENCY: Go scanner concurrency - DEV_AGENT_CONCURRENCY: General fallback concurrency These changes ensure robust Go support for production use while maintaining backward compatibility and improving the overall developer experience.
Resolved conflict in README.md by combining v0.6.0 Go support with performance improvements into a unified release entry.
The lockfile was out of sync with packages/core/package.json after adding tree-sitter-wasms dependency. This ensures CI builds work correctly with the new Go scanner dependencies.
Remove all Renovate configuration files, workflows, and documentation: - renovate.json5 and renovate.json (main configuration) - .github/renovate-automerge.json5 (automerge settings) - .github/renovate-groups.json5 (package grouping) - .github/workflows/renovate.yml (GitHub Actions workflow) - docs/DEPENDENCY_MANAGEMENT.md (Renovate documentation) Dependencies will now be managed manually to give more control over updates and reduce automated PR noise.
