# Ejemplos Prácticos: Validación de Archivos en Klaus
**Objetivo:** Mostrar cómo funciona la validación en UNA PASADA para diferentes tipos de archivos
---
## Caso 1: Archivo Python (CODE_PYTHON)
### Input
```
File: proxy/knowledge.py
Size: 45 KB
Content (first 100 chars):
"""Knowledge base — project file indexing and semantic Q&A via Qdrant.
Colección separada del caché semántico...
```
### Validación (Fase 1-3)
```
FASE 1: detect_file_category(file_path, content_sample)
├─ Extension check: .py
│ └─ MATCH: CODE_PYTHON
└─ Return: FileCategory.CODE_PYTHON
FASE 2: should_index_file(file_path, category, content)
├─ Size check: 45 KB < 50 MB ✓
├─ Category check: CODE_PYTHON
│ └─ Policy: INDEX ✓
├─ LLM response check: is_llm_response(content)
│ └─ Pattern match: No LLM starters ✓
└─ Return: (True, "category_code_python_index")
FASE 3: ChunkingPolicy.for_category(category)
└─ Return: {
strategy='ast',
chunk_size=500,
overlap=0,
extract_symbols=True,
preserve_structure=True,
}
```
### Chunking Result
```
File: proxy/knowledge.py
Chunks: 15 (via AST parsing)
├─ Chunk 0: def _tokenize(text: str) → [lines 140-142]
├─ Chunk 1: def _sparse_vector(text: str) → [lines 145-158]
├─ Chunk 2: def is_llm_response(content: str) → [lines 161-184]
├─ Chunk 3: class ChunkingPolicy → [dataclass definition]
├─ Chunk 4: def embed_text(...) → [lines 187-211]
├─ Chunk 5: def _chunk_python(file_path, content) → [lines 233-286]
├─ Chunk 6: def _chunk_markdown(file_path, content) → [lines 289-312]

├─ Chunk 13: async def get_stats() → [lines 1047-1058]
└─ Chunk 14: async def flush() → [lines 1078-1089]
Module-level code (imports, docstring):
├─ Chunk 15: Imports + module docstring → [lines 1-140]
```
### Embedding & Storage
```
Chunk 0 (symbol: "_tokenize", type: "function")
├─ Semantic prefix: "proxy/knowledge.py: function _tokenize —"
├─ Full text: "proxy/knowledge.py: function _tokenize — def _tokenize(text..."
├─ Embed → vector (1536 dims)
├─ Quality score: 0.85 (function, >100 chars)
├─ Store in Qdrant:

│ │ symbol_type: "function",
│ │ quality_score: 0.85,
│ │ language: "python",
│ │ }
│ └─ id: uuid5("proxy/knowledge.py:0:...")
└─ Status: STORED ✓
```
### Métricas Resultantes
```
proxy/knowledge.py:
Category: CODE_PYTHON

```
### Búsqueda: ¿Cómo funciona la recuperación?
Query: "¿Cuántas réplicas tiene el deployment?"
```
Vector search:
Query text: "¿Cuántas réplicas tiene el deployment?"
Query vector: [0.23, -0.15, 0.89, ...] (embedded)
Dense search (cosine similarity):
├─ Score config/kubernetes/deployment.yaml:chunk_1: 0.82 ✓ MATCH
│ └─ Contains "replicas: 3"
├─ Score config/kubernetes/deployment.yaml:chunk_0: 0.45
└─ Score other_file.yaml:chunk_X: 0.31
Sparse search (BM25):
├─ "deployment", "replicas", "kubernetes" are TF tokens
└─ RRF fusion combines rankings
Result:
└─ config/kubernetes/deployment.yaml:chunk_1 (score: 0.82)
Content: "replicas: 3"

## Interpretación de Resultados
### "¿Debería haber más archivos indexados?"
```
Indexation rate: 88.9%
Expected: 75-95%
Analysis:
✓ 88.9% está en el rango esperado
✓ Los 11.1% skipped son categorías sensatas
(vendored, tests, binaries, logs)
Conclusión: Distribución CORRECTA
```
### "¿Por qué tanto vendored skipped?"
```
category_vendored_skip: 3500 files (37%)
Reason:
- node_modules/: ~2500 files (npm packages)
- vendor/: ~500 files (PHP packages)
- dist/, build/: ~500 files (compiled output)
Conclusion: ESPERADO — código externo, no proyecto
No es contenido a indexar
```
### "¿Qué significa chunks_stored: 35,891?"
```
8,328 indexed files × 4.3 avg chunks/file = 35,891 chunks
Breakdown:
- CODE: ~1,100 files × 8 chunks = 8,800 chunks
- DOCS: ~740 files × 3 chunks = 2,220 chunks
- CONFIG: ~2,854 files × 1.5 chunks = 4,281 chunks
- Module code: Various = ~20,590 chunks
Total: ~35,891 ✓
Average chunk size: ~12 KB (45 MB / 35,891 chunks)
Reasonable: 8 KB - 15 KB per chunk is good
```
