Project-Specific Guidelines

Current Database Usage

1. SQLite (orchestrator/context/graph_store.py)

   • Graph context storage
   • FTS5 for full-text search
   • JSON columns for flexible properties

2. Schema Structure

-- Current schema in graph_store.py
CREATE TABLE nodes (
    id TEXT PRIMARY KEY,
    node_type TEXT NOT NULL,
    title TEXT,
    content TEXT,
    metadata TEXT DEFAULT '{}',  -- JSON
    tags TEXT DEFAULT '[]',       -- JSON array
    created_at TEXT NOT NULL,
    updated_at TEXT NOT NULL,
    importance_score REAL DEFAULT 1.0,
    extra_data TEXT DEFAULT '{}'  -- JSON for type-specific fields
);

CREATE TABLE edges (
    id TEXT PRIMARY KEY,
    source_id TEXT NOT NULL,
    target_id TEXT NOT NULL,
    edge_type TEXT NOT NULL,
    weight REAL DEFAULT 1.0,
    metadata TEXT DEFAULT '{}',
    created_at TEXT NOT NULL,
    FOREIGN KEY (source_id) REFERENCES nodes(id) ON DELETE CASCADE,
    FOREIGN KEY (target_id) REFERENCES nodes(id) ON DELETE CASCADE
);

CREATE TABLE embeddings (
    node_id TEXT PRIMARY KEY,
    embedding BLOB NOT NULL,
    model_name TEXT,
    created_at TEXT NOT NULL,
    FOREIGN KEY (node_id) REFERENCES nodes(id) ON DELETE CASCADE
);

-- FTS5 for full-text search
CREATE VIRTUAL TABLE nodes_fts USING fts5(
    id, title, content, tags,
    content='nodes',
    content_rowid='rowid'
);
