`classify_as_spare_part(category: str) -> bool` — Scoring algorithm with fuzzy matching, regex patterns, exclusion rules + - `is_consumable(category: str) -> bool` — Inverse classification + - `get_spare_part_type(category: str) -> Optional[str]` — Normalized type extraction for search queries +- **Key features:** + - 33-item spare parts whitelist (RAM, SSD, CPU, GPU, PSU, etc.) + - 14-item consumable keyword list (cables, fasteners, thermal materials) + - Fuzzy matching at 70-80% threshold (FuzzyWuzzy library) + - Regex pattern matching for common categories + - Special case handling (power supply vs. power cable distinction) + - Scoring algorithm: ≥40 points → spare part, <40 → consumable +- **Acceptance criteria:** ✓ All passed + - Exact match tests: Kingston DDR4 RAM → True, 6ft SATA Cable → False + - Fuzzy match: "Random Access Memory" → True (DDR4 equivalent) + - Edge case: "Corsair RM850x 850W PSU" → True, "6ft Power Cable AC Cord" → False + - Type hints and docstrings included + +### Task 2: Enhance Gemini AI Prompt ✓ +- **File modified:** `config/ai_prompt.md` (added 37 lines) +- **Section added:** "Spare-Parts vs Consumables Classification" (post "Other Fields") +- **Content includes:** + - Detailed spare parts list with technical description + - Consumables exclusion list with examples + - Decision tree logic (3-question qualification check) + - 8 concrete examples (4 spare parts + 4 consumables with classification rationale) +- **Integration:** Prompt now used by both Gemini and Claude extractors via shared `config/ai_prompt.md` +- **Acceptance criteria:** ✓ All passed + - Classification guide present with decision tree + - Examples included (Kingston Fury RAM, 6ft Cable, etc.) + - Prompt structure preserved, JSON output format intact + +### Task 3: Enhance Claude AI Prompt ✓ +- **File modified:** `config/ai_prompt.md` (same file as Task 2) +- **Scope:** Identical classification guide shared with Gemini +- **Impact:** Both AI providers now receive consistent spare-parts classification instructions +- **Acceptance criteria:** ✓ All passed + - Content identical to Gemini classification guide + - Maintains Claude SDK compatibility + +### Task 4: Create Unit Tests for Classification ✓ +- **File created:** `tests/test_spare_parts_classification.py` (191 lines) +- **Test coverage:** + - **Exact match tests:** 4 test methods (RAM, storage, processors, power supplies) + - **Consumable tests:** 3 test methods (cables, fasteners, thermal materials) + - **Fuzzy match tests:** 2 test methods (RAM variants, storage variants) + -
