Description
Typed knowledge graph for AI agent memory. Create entities, link relations, enforce constraints. JSONL append-only storage, zero dependencies. Use when agent...
Usage Guidance
Do not install or enable this skill until you confirm where the implementation lives. Questions to ask the publisher: (1) Where are scripts/ontology.py and any supporting code? The SKILL.md's CLI examples rely on that file. (2) If the code is provided separately, inspect it for filesystem and network access before running. (3) If you intend the agent to implement these semantics itself, understand the agent will create and modify memory/ontology/graph.jsonl (local files) — back up that folder and restrict file permissions. (4) Verify how credentials are handled: the schema requires secret_ref (good), but confirm the runtime never writes secrets into the JSONL. If the author cannot provide source code or a clear install path, treat the package as incomplete and avoid enabling autonomous invocation.
Capability Analysis
Type: OpenClaw Skill
Name: ontology-kg
Version: 1.0.0
The ontology-kg skill bundle provides a structured knowledge graph system for AI agent memory, using JSONL for storage. The documentation (SKILL.md, schema.md) defines clear entity types and relations with a focus on security, such as explicitly forbidding the storage of raw secrets in Credential entities. No malicious instructions, data exfiltration patterns, or suspicious execution commands were identified in the provided files.
Capability Assessment
Purpose & Capability
The skill claims a zero-dependency JSONL store for a typed KG, which is coherent, but the SKILL.md examples and references assume a Python CLI (scripts/ontology.py). No such scripts or install steps are included in the package or manifest. That leaves a missing implementation: either the agent must implement the behavior itself or the package is incomplete.
Instruction Scope
Instructions tell the agent to create/read/relate/validate entities by running python scripts that read/write memory/ontology/graph.jsonl. The instructions reference local filesystem paths and document paths (which could point to arbitrary local files). While the described operations are appropriate for a memory/ontology tool, the SKILL.md grants implicit permission to read/write local files and to run arbitrary Python scripts — and since the scripts aren't provided, it's unclear what code would run.
Install Mechanism
There is no install spec (instruction-only), which is low risk in principle. However, the lack of included implementation while instructing use of specific scripts is an inconsistency: either an install or code files should be present or the SKILL.md should explain how the agent provides equivalent functionality.
Credentials
The skill requests no environment variables or credentials. The schema references secret_ref for credentials (encouraging not storing secrets directly), which is a reasonable safety constraint. There are no declared env/credential requirements that appear disproportionate.
Persistence & Privilege
always is false and model invocation is permitted (defaults). The skill does instruct writing to a local graph.jsonl (agent-local storage), which is expected for a memory tool. No indications it attempts to change other skills or gain elevated platform privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install ontology-kg - After installation, invoke the skill by name or use
/ontology-kg - Provide required inputs per the skill's parameter spec and get structured output
