What is knowledge-graph-manager?

A tool that turns Markdown notes into a linked knowledge graph, a structured map of people, projects, meetings, topics, and relationships. It lets you search that map with plain-language questions or SPARQL, a query language for linked data.

Use it to convert a Markdown vault into RDF/Turtle files, find people or projects, inspect meeting history, and discover links between entities.

It removes the need to scan many notes manually or keep relationships only in your head. Converting notes into structured data makes connections easier to find.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00030	$0.01337
Opus 5.5	$0.00012	$0.00535
Sonnet 5.5	$0.00006	$0.00267
Haiku 4.5	$0.00003	$0.00134

Measured 2mo ago against content hash 626cf57156b9, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

knowledge-graph-manager scanned grade A with 0 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Knowledge Graph Manager

Convert markdown vault to RDF/TTL knowledge graph and query with SPARQL.

Overview

This agent transforms markdown files into a semantic knowledge graph (RDF/TTL format) and provides natural language querying via SPARQL.

Key Features

Vault → TTL Conversion: Parse markdown files to RDF triples
SPARQL Queries: 17+ preset queries for common use cases
Natural Language Interface: Ask questions about your data

Trigger Phrases

"Build knowledge graph"
"Sync vault to TTL"
"Query the graph"
"Search for [keyword]"
"Show all [entities]"
"Find relationships"

Workflow

1. Build/Sync Knowledge Graph

Convert vault markdown files to TTL:

source .venv/bin/activate && \
python .claude/skills/ontology-engine/scripts/vault_to_ttl.py ./vault --output ./knowledge.ttl

What gets extracted:

Person: From persons/ folder (configurable)
Project: From projects/ folder (configurable)
Meeting: From ## YYYY.MM.DD heading sections
Organization: From filename pattern Name_Org.md
Topic: From hashtags and keywords in content
Relationships: From [[wikilinks]] → knows/involvedIn

2. Query Knowledge Graph

Run SPARQL queries:

source .venv/bin/activate && \
python .claude/skills/ontology-query/scripts/query_knowledge.py ./knowledge.ttl \
  --preset <preset_name> --param "<value>"

`all_persons`	All persons	-
`person_meetings`	Meetings with person	Name
`person_topics`	Topics discussed with person	Name
