knowledge-graph-system CLAUDE.md

Developer instructions for a document system that turns text into connected concept graphs stored in PostgreSQL. Apache AGE is a PostgreSQL extension for graph data, and Docker runs the system's services in containers.

In plain words
What is it for?
Use them when starting the containers, updating images, working on the API, web interface, graph storage, document extraction, or optional command-line and MCP tools.
Why use it?
They describe the system's components and lifecycle so agents can update or operate it without requiring a local Python installation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade D, and why

knowledge-graph-system CLAUDE.md scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

sudo ./operator.sh upgrade # Pull images, migrate, restart apps

Knowledge Graph System - Claude Development Guide

Project Overview

A multi-dimensional knowledge extraction system that transforms documents into interconnected concept graphs using Apache AGE (PostgreSQL graph extension).

Fully Containerized - no local Python installation required.

                   MCP Server (optional)

Tech Stack:

  • Python 3.11+ FastAPI (REST API server)
  • Apache AGE / PostgreSQL 16 (graph database, openCypher)
  • TypeScript/Node.js (CLI + MCP)
  • React/Next.js (web visualization)
  • Garage (S3-compatible storage)
  • Docker Compose (orchestration)

Quick Start

Production deployment (standalone installer):

curl -fsSL https://raw.githubusercontent.com/aaronsb/knowledge-graph-system/main/install.sh | bash

Development setup (from repo):

git clone https://github.com/aaronsb/knowledge-graph-system.git
cd knowledge-graph-system
./operator.sh init    # Guided setup
./operator.sh start   # Daily start

Optional CLI:

cd cli && npm run build && ./install.sh
kg health

Platform Lifecycle

operator.sh is the primary management tool (apt-style commands):

# Updates (pull images, no restart)
./operator.sh update             # Pull all images
./operator.sh update api         # Pull specific service

# Upgrades (pull, migrate, restart)
./operator.sh upgrade            # Full upgrade
./operator.sh upgrade --dry-run  # Preview changes

# Daily operations
./operator.sh start              # Start platform
./operator.sh stop               # Stop platform
./operator.sh status             # Check health
./operator.sh logs api -f        # Follow API logs
./operator.sh shell              # Configuration shell

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

knowledge-graph-system CLAUDE.md is an instructions file published in the GitHub repository aaronsb/knowledge-graph-system (124 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 2,036 tokens to every session, about $0.0102 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
