From fcab559368711d732f8ba1c837a25669566154c0 Mon Sep 17 00:00:00 2001 From: Leo Meyerovich Date: Sun, 6 Jul 2025 19:29:10 -0700 Subject: [PATCH 01/22] feat: Add comprehensive GFQL LLM specifications and validation framework MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit implements a complete system for GFQL LLM integration and validation: ## GFQL LLM-Friendly Specifications - **Language Specification**: Complete EBNF grammar and operation documentation - **Wire Protocol**: JSON schema for type-safe serialization - **Cypher Mapping**: Translation guide between Cypher and GFQL - **Synthesis Examples**: LLM-optimized code generation patterns ## Validation Framework - **Core API**: validate_syntax(), validate_schema(), validate_query() - **Schema Extraction**: Auto-extract from DataFrames and Plottables - **Error Handling**: Structured ValidationIssue with suggestions - **Custom Exceptions**: GFQL-specific exception hierarchy ## Documentation & Notebooks - **4 Validation Guides**: Fundamentals, Advanced, LLM Integration, Production - **84 Interactive Cells**: Comprehensive examples for all user types - **Sphinx Integration**: Complete RST documentation structure - **Cross-References**: Seamless navigation between specs and guides ## Testing & Quality - **44 Unit Tests**: Complete coverage of validation functionality - **CI Ready**: All tests pass, documentation builds successfully - **Type Safety**: Full type annotations with mypy compatibility This enables robust LLM code generation for GFQL with comprehensive validation and error handling for production use. ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- ai_code_notes/gfql/README.md | 212 +++

MATCH` - Handle nulls in post-processing +- `WITH` clauses - Use intermediate chains +- `ORDER BY/LIMIT` - Use pandas after +- `CREATE/DELETE` - GFQL is read-only + +## ๐Ÿงช Validation Checklist + +Before generating GFQL: +1. โœ“ Check column names exist in schema +2. โœ“ Verify predicate types match column types +3. โœ“ Ensure temporal values use proper types +4. โœ“ Validate operation names

+1. **GFQL is functional**: Chain operations, don't mutate +2. **Filter early**: Put selective conditions first +3. **Think patterns**: Focus on graph patterns, not procedures +4. **Post-process**:

Matching**: `(a)-[r]->(b)` โ†’ `chain([n(), e_forward(), n()])` +2. **WHERE Embedding**: Move WHERE conditions into matchers +3. **Path Length**: `*N` โ†’ `hops=N`, `*` โ†’ `to_fixed_point=True` +4. **Labels**: `:Label` โ†’ `{"type": "Label"}` or `{"label": "Label"}` + +### For Optimization + +1. **Filter Early**: Put selective filters in first operations +2. **Limit Hops**: Use specific hop

-## Error Cases - -### Common Synthesis Errors - -**Error**: Using unsupported Cypher features -```python -# Incorrect - OPTIONAL MATCH is not supported -# OPTIONAL MATCH (n)-[r]->(m) - -# Correct - Handle optionality in post-processing -g.chain([n(), e_forward()]) -# Then check for nulls in results -``` - -**Error**: Aggregations in chain -```python -# Wrong - Can't aggregate in chain -# g.chain([n(), e(), count()]) - -# Correct - Aggregate after -result = g.chain([n(), e()]) -count = len(result._edges) -``` - -**Error**: Wrong predicate types -```python -# Wrong - String predicate on number -# n({"age": contains("3")}) - -# Correct - Use numeric predicate -n({"age": gt(30)}) -``` - -### Validation Examples - -**Schema Validation**: -```python -# Given schema: nodes have ['id', 'type', 'name'] -# Wrong: -g.chain([n({"username": "Alice"})]) # 'username' doesn't exist - -# Correct: -g.chain([n({"name": "Alice"})]) -``` - -**Type Validation**: -```python -# Given: 'created' is a datetime column -# Wrong: -n({"created": gt("2024-01-01")}) # String instead of datetime - -# Correct: -n({"created": gt(pd.Timestamp("2024-01-01"))}) -``` - -## Synthesis Tips - -### For Natural Language Processing - -1. **Identify Entities**: Look for nouns that map to node types -2. **Identify Relationships**: Look for verbs that map to edge types -3. **Extract Filters**: Look for adjectives and conditions -4. **Determine Direction**: "from", "to", "by" indicate direction -5. **Handle Time**: "recent", "last N days", "since" map to temporal predicates - -### For Cypher Translation - -1. **Pattern Matching**: `(a)-[r]->(b)` โ†’ `chain([n(), e_forward(), n()])` -2. **WHERE Embedding**: Move WHERE conditions into matchers -3. **Path Length**: `*N` โ†’ `hops=N`, `*` โ†’ `to_fixed_point=True` -4. **Labels**: `:Label` โ†’ `{"type": "Label"}` or `{"label": "Label"}` - -### For Optimization - -1. **Filter Early**: Put selective filters in first operations -2. **Limit Hops**: Use specific hop counts when possible -3. **Name Results**: Use `name` parameter for important nodes/edges -4. **Combine Filters**: Put multiple conditions in one operation -
