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 want Ensue to store and search your persistent knowledge. Review drafts before saving, avoid secrets or highly sensitive personal details, and keep the Ensue API key scoped to an account you trust for this data.
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 skill describes saving, searching, retrieving, updating, and deleting second-brain knowledge, and the documented Ensue API operations match that purpose.
Instruction Scope
The trigger phrases are broad and include common language, but the artifact gives clear intent mapping, draft-and-confirm rules for saves, confirmation for deletes, and explicit anti-patterns against auto-saving or storing secrets.
Install Mechanism
The bundle uses a disclosed shell wrapper around curl to call the Ensue API and requires ENSUE_API_KEY; there is no hidden installer, package install, obfuscation, or unrelated execution path.
Credentials
Saved entries and search queries are sent to Ensue's external API, which is privacy-relevant but proportionate for a cloud-backed knowledge-base integration and disclosed through the API-key and endpoint usage.
Persistence & Privilege
The skill intentionally creates persistent remote memory entries and can update or delete them, but that authority is central to the purpose and bounded by user-facing confirmation guidance for mutating actions.
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
