From a565b87a90372b84957e77c1146f4e41215b1add Mon Sep 17 00:00:00 2001 From: yusyus Date: Thu, 5 Feb 2026 22:02:06 +0300 Subject: [PATCH] fix: Framework detection now works by including import-only files (fixes #239) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem Framework detection was broken because files with only imports (no classes/functions) were excluded from analysis. The architectural pattern detector received empty file lists, resulting in 0 frameworks detected. ## Root Cause In codebase_scraper.py:873-881, the has_content check filtered out files that didn't have classes, functions, or other structural elements. This excluded simple __init__.py files that only contained import statements, which are critical for framework detection. ## Solution (3 parts) 1. **Extract imports from Python files** (code_analyzer.py:140-178) - Added import extraction using AST (ast.Import, ast.ImportFrom) - Returns imports list in analysis results - Now captures: "from flask import Flask" → ["flask"] 2. **Include import-only files** (codebase_scraper.py:873-881) - Updated has_content check to include files with imports - Files with imports are now included in analysis results - Comment added: "IMPORTANT: Include files with imports for framework detection (fixes #239)" 3. **Enhance framework detection** (architectural_pattern_detector.py:195-240) - Extract imports from all Python files in analysis - Check imports in addition to file paths and directory structure - Prioritize import-based detection (high confidence) - Require 2+ matches for path-based detection (avoid false positives) - Added debug logging: "Collected N imports for framework detection" ## Results **Before fix:** - Test Flask project: 0 files analyzed, 0 frameworks detected - Files with imports: excluded from analysis - Framework detection: completely broken **After fix:** - Test Flask project: 3 files analyzed, Flask detected ✅ - Files with imports: included in analysis - Framework detection: working correctly - No false positives (ASP.NET, Rails, etc.) ## Testing Added comprehensive test suite (tests/test_framework_detection.py): - ✅ test_flask_framework_detection_from_imports - ✅ test_files_with_imports_are_included - ✅ test_no_false_positive_frameworks All existing tests pass: - ✅ 38 tests in test_codebase_scraper.py - ✅ 54 tests in test_code_analyzer.py - ✅ 3 new tests in test_framework_detection.py ## Impact - Fixes issue #239 completely - Framework detection now works for Python projects - Import-only files (common in Python packages) are properly analyzed - No performance impact (import extraction is fast) - No breaking changes to existing functionality Co-Authored-By: Claude Sonnet 4.5 --- .../cli/architectural_pattern_detector.py | 30 ++- src/skill_seekers/cli/code_analyzer.py | 16 +- src/skill_seekers/cli/codebase_scraper.py | 22 +- tests/test_framework_detection.py | 192 ++++++++++++++++++ 4 files changed, 249 insertions(+), 11 deletions(-) create mode 100644 tests/test_framework_detection.py diff --git a/src/skill_seekers/cli/architectural_pattern_detector.py b/src/skill_seekers/cli/architectural_pattern_detector.py index 3608204..57e6279 100644 --- a/src/skill_seekers/cli/architectural_pattern_detector.py +++ b/src/skill_seekers/cli/architectural_pattern_detector.py @@ -200,6 +200,16 @@ class ArchitecturalPatternDetector: all_paths = [str(f.get("file", "")) for f in files] all_content = " ".join(all_paths) + # Extract all imports from Python files (fixes #239) + all_imports = [] + for file_data in files: + if file_data.get("language") == "Python" and file_data.get("imports"): + all_imports.extend(file_data["imports"]) + + # Create searchable import string + import_content = " ".join(all_imports) + logger.debug(f"Collected {len(all_imports)} imports for framework detection") + # Also check actual directory structure for game engine markers # (project.godot, .unity, .uproject are config files, not in analyzed files) dir_files = [] @@ -227,15 +237,27 @@ class ArchitecturalPatternDetector: # Return early to prevent web framework false positives return detected -
