English | 中文

AI-powered data generation plugin for sqlseed.

LLM-driven schema analysis, self-correcting config generation, and template pool assistance. Uses OpenAI-compatible API (default: OpenRouter free models).

Installation

pip install sqlseed-ai

Quick Start

# Set API key (OpenRouter, OpenAI, DeepSeek, etc.)
export SQLSEED_AI_API_KEY="your-api-key"

# Generate AI-suggested YAML config
sqlseed ai-suggest app.db --table users --output users.yaml

# With self-correction (3 rounds by default)
sqlseed ai-suggest app.db --table users --output users.yaml --verify

# Specify model
sqlseed ai-suggest app.db --table users -o users.yaml --model deepseek/deepseek-chat

# Skip cache
sqlseed ai-suggest app.db --table users -o users.yaml --no-cache

Features

Schema Analyzer

SchemaAnalyzer extracts rich context from your database (columns, indexes, sample data, foreign keys, data distribution) and builds a structured prompt for LLM analysis. Returns column-level generation configs as JSON.

Self-Correcting Refiner

AiConfigRefiner validates LLM output against actual schema:

1. LLM generates column config
2. Refiner checks for unknown generators, type mismatches, expression errors
3. If errors found, sends correction request back to LLM
4. Up to 3 retry rounds, then raises AISuggestionFailedError

Auto Model Selection

Queries OpenRouter API to find the best available free model. Falls back through a priority list:

nvidia/nemotron-3-super-120b-a12b:free → tencent/hy3-preview:free → ...

Result cached for 1 hour. Skip auto-selection by specifying --model or SQLSEED_AI_MODEL.

Template Pool

When sqlseed fills a table with skip_ai=False, the plugin pre-generates candidate values for columns that can't be mapped to a deterministic generator (via sqlseed_pre_generate_templates hook).

File Caching

AI configs cached in .sqlseed_cache/ai_configs/ with schema hash validation. Schema changes auto-invalidate cache. Use --no-cache to skip.

Configuration

Environment Variables

Variable	Fallback	Default	Description
SQLSEED_AI_API_KEY	OPENAI_API_KEY	—	API key (required)
SQLSEED_AI_BASE_URL	OPENAI_BASE_URL	https://openrouter.ai/api/v1	API endpoint
SQLSEED_AI_MODEL	—	auto-select	Model name
SQLSEED_AI_TIMEOUT	—	60	API timeout (seconds)

CLI Options

--model, -m       Model name (overrides auto-selection)
--api-key         API key (overrides env)
--base-url        API base URL (overrides env)
--max-retries     Self-correction rounds (default: 3, 0=disable)
--verify/--no-verify  Toggle self-correction (default: verify)
--no-cache        Skip file cache
--timeout         API timeout in seconds (default: 120)

Plugin Hooks

This plugin registers via [project.entry-points."sqlseed"] and implements:

Hook	Purpose
sqlseed_ai_analyze_table	LLM-driven table analysis, returns column configs
sqlseed_pre_generate_templates	Pre-generate candidate values for complex columns
sqlseed_register_providers	Placeholder (no-op, entry-point registration)
sqlseed_register_column_mappers	Placeholder (no-op, entry-point registration)

Requirements
