Description
Reference tool for devtools — covers intro, quickstart, patterns and more. Quick lookup for System Hardener concepts, best practices, and implementation patt...
Usage Guidance
This skill appears to be a harmless, self-contained reference tool: it only prints builtin documentation and does not access the network or secrets. If you plan to run the bundled script, you can safely inspect scripts/script.sh locally (it is plain shell with heredocs) before invoking. Note the small non-security issues: metadata version (2.0.1) does not match the script's VERSION (2.0.0) and the help heredoc uses single quotes so $VERSION will not expand — both are benign maintenance issues. If you require absolute assurance, request the maintainer to bump the embedded VERSION to match the package and confirm there are no planned updates that would introduce external network or credential usage.
Capability Analysis
Type: OpenClaw Skill
Name: system-hardener
Version: 2.0.1
The 'system-hardener' skill bundle is a documentation reference tool that provides static text information about security best practices. The primary script (scripts/script.sh) only outputs plain-text documentation via heredocs and contains no network activity, file system modifications, or credential access. The SKILL.md instructions are consistent with the script's functionality and lack any indicators of prompt injection or malicious intent.
Capability Assessment
Purpose & Capability
The name/description (reference for System Hardener concepts) aligns with the included materials (plain-text reference outputs). There is a minor metadata vs. script mismatch (package version 2.0.1 vs. script VERSION=2.0.0) but this appears to be a benign bookkeeping inconsistency.
Instruction Scope
SKILL.md explicitly states the commands output plain-text docs and require no network or credentials. The runtime script only emits heredoc text and uses basic shell control flow; it does not read files, access environment secrets, make network calls, or transmit data externally.
Install Mechanism
No install spec is provided (instruction-only behavior). A single helper script is bundled but it does not perform downloads, extraction, or write outside its own execution — low install risk.
Credentials
The skill requests no environment variables or credentials and the script does not reference any secret env vars or config paths. No disproportionate access is requested.
Persistence & Privilege
The skill does not request permanent presence (always=false) and does not modify agent or system configurations. It can be invoked autonomously by the agent (default), which is expected for skills, but there are no additional privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install system-hardener - After installation, invoke the skill by name or use
/system-hardener - Provide required inputs per the skill's parameter spec and get structured output
