# Changelog

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

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [4.2.2] - 2025-06-11

### Fixed
- **Evaluation Prompt Instructions**: Strengthened evaluation prompts to prevent improvement suggestions
  - Added CRITICAL, FORBIDDEN, and FINAL REMINDER directives to ensure pure developer assessment
  - Prevents AI models from suggesting code improvements when evaluation is requested
  - Ensures focus remains on skill assessment, AI assistance detection, and professional maturity

### Improved
- **Semantic Chunking Optimization**: Significantly reduced API calls through better batch consolidation
  - Now attempts to fit all threads in a single batch when possible
  - Smart merging of smaller semantic groups to minimize batch count
  - Increased thread limit per batch from 15 to 30
  - Example: 21 threads now consolidate into 1 batch instead of 3 (67% reduction in API calls)

## [4.2.1] - 2025-06-11

### Fixed
- **Missing Evaluation Prompt**: Added evaluation review type to bundled prompts
  - Fixes "No prompt template found for evaluation" error when using npx or published package
  - Evaluation review type was defined but not accessible in bundled prompts
  - Now includes comprehensive developer skill assessment framework in bundled prompts

## [4.2.0] - 2025-06-11

### Added

  - Includes meta coding quality indicators (documentation, testing, workflow)
  - Structured schema output for consistent evaluation results
- **Golang Language Support**: Comprehensive support for Go/Golang projects
  - Golang-specific prompt templates for all review types (architectural, quick-fixes, security, performance, unused-code, best-practices, evaluation)
  - Idiomatic Go pattern analysis and best practices
  - Go project type detection and file filtering (.go, go.mod, go.sum)
  - Concurrency, interface design, and error handling expertise
- **Enhanced Grading System**: Academic-style grading for consolidated reviews
  - A+ to F grading scale for code quality assessment

### Updated
- Version bumped to 4.2.0 to reflect significant new functionality

### Fixed
- Removed duplicate `-i` flag documentation in README

## [4.1.0] - 2025-06-07

## [4.0.0] - 2025-06-04

### Added
- **🧠 AI-Guided Semantic Chunking with TreeSitter Integration**
  - Real AST parsing for TypeScript, JavaScript, Python, Ruby using TreeSitter
  - Intelligent code structure boundaries preserving functions/classes/modules
  - AI-guided chunking strategy selection based on review type and code complexity
  - 95%+ token reduction (from 196K+ to ~4K tokens in typical cases)
  - Context limit problem resolution - no more 200K token failures
- **Environment Variable Control for Semantic Chunking**
  - New `AI_CODE_REVIEW_ENABLE_SEMANTIC_CHUNKING` environment variable (default: true)
  - CLI flag override: `--enable-semantic-chunking` for runtime control
  - Configuration precedence: CLI flag > env var > default
  - Debug logging for chunking decisions and environment variable status
- **5 Intelligent Chunking Strategies**
  - `individual`: Each declaration reviewed separately (high complexity code)
  - `grouped`: Related small declarations together (utility functions)
  - `hierarchical`: Classes with their methods (object-oriented code)
  - `functional`: Related business logic grouped (feature-based code)
  - `contextual`: Preserves import/dependency context (complex dependencies)
- **Review Type Optimization**
  - Architectural reviews → hierarchical chunking for class structures
  - Security reviews → contextual chunking for data flow analysis
  - Performance reviews → functional chunking for execution paths
  - Quick-fixes → individual chunking for focused analysis
- **Robust 4-Level Fallback System**
  - Semantic chunking (TreeSitter + AI-guided) → Line-based chunking (500-line chunks) → Individual file processing → Emergency fallback
  - Graceful degradation ensures no review failures
- **Comprehensive Documentation**
  - Complete semantic chunking guide (`SEMANTIC_CHUNKING.md`)
  - Technical implementation status (`TREESITTER_IMPLEMENTATION_STATUS.md`)
  - Environment variable documentation in `.env.example` and `.env.sample`
  - Updated `PROJECT.md` with configuration details

### Changed

  - Specific technical recommendations vs generic suggestions
- **Enhanced Performance**
  - 40-100ms analysis time with TreeSitter parsing
  - Significant API cost reduction through token efficiency
  - Reliable operation for large codebases that previously failed
- **Better Code Structure Analysis**
  - Real syntax tree understanding vs text-based chunking
  - Preserved semantic relationships between code elements
  - Intelligent boundary detection at function/class levels

### Technical Details
