Description
Personal knowledge base powered by Ensue for capturing and retrieving understanding. Use when user wants to save knowledge, recall what they know, manage their toolbox, or build on past learnings. Triggers on "save this", "remember", "what do I know about", "add to toolbox", "my notes on", "store this concept".
Usage Guidance
Install this only if you intend to use Ensue as a cloud-backed persistent memory service. Review every draft before saving, do not store secrets or highly sensitive personal data, and use an API key you are comfortable granting access to this knowledge base.
Capability Analysis
Type: OpenClaw Skill
Name: second-brain
Version: 0.1.4
The skill bundle is designed for a 'second-brain' knowledge base using the Ensue API. The `SKILL.md` file provides clear instructions for the AI agent, explicitly warning against storing sensitive data (credentials, API keys, private paths) and logging API keys, and emphasizes user confirmation for actions. The `scripts/ensue-api.sh` script securely retrieves the `ENSUE_API_KEY` from an environment variable and uses it to authenticate with the `api.ensue-network.ai` endpoint via `curl`. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or prompt injection with harmful intent. All components align with the stated purpose and follow good security practices.
Capability Assessment
Purpose & Capability
The stated purpose is to save, search, update, delete, and retrieve second-brain knowledge entries, and the documented Ensue API operations match that purpose.
Instruction Scope
The skill gives concrete triggers, requires confirmation and draft review before saving, confirms deletes, and explicitly warns against storing credentials, secrets, private paths, or system details.
Install Mechanism
The bundle contains one executable shell wrapper that calls the Ensue API with curl. This is disclosed in SKILL.md and is proportionate, but a tighter manifest-level command permission would improve reviewability if the platform supports it.
Credentials
The skill requires ENSUE_API_KEY and sends note contents and search queries to Ensue's external API. That is expected for a cloud-backed knowledge-base integration, but it is still a privacy-relevant data flow.
Persistence & Privilege
The skill intentionally creates persistent remote memory entries and can update or delete them. This is central to its purpose and is bounded by user-confirmation instructions for saves and deletes.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install second-brain - After installation, invoke the skill by name or use
/second-brain - Provide required inputs per the skill's parameter spec and get structured output
