Usage Guidance
This skill is instruction-only and appears internally consistent with its purpose, so installing it carries low intrinsic risk. Before using it: (1) confirm the publisher/owner (registry metadata and _meta.json disagree); (2) avoid pasting secrets or sensitive data into regex tests—any data you provide to the agent may be processed or logged by the agent environment; (3) ask which regex flavor the agent will use (JS, PCRE, Python, etc.) if exact matching behavior matters; and (4) because the skill has no code, its behavior depends on the agent implementation—test it with harmless examples first.
Capability Analysis
Type: OpenClaw Skill
Name: regex-playground
Version: 1.0.0
The regex-playground skill bundle is a documentation-only package providing instructions for an AI agent to assist with regular expression testing and learning. It contains no executable code, installation scripts, or suspicious prompt-injection attempts in SKILL.md, and its functionality is entirely consistent with its stated purpose.
Capability Assessment
Purpose & Capability
The name/description (regex learning and testing) matches the SKILL.md content. The skill is instruction-only and does not request credentials, binaries, or config paths. Minor metadata inconsistencies exist: registry metadata lists ownerId 'kn78bfpa…' and version 1.0.0, while _meta.json shows ownerId 'openclaw' and version 0.1.0; this looks like an administrative mismatch but does not change the runtime footprint.
Instruction Scope
SKILL.md contains only user-facing commands and examples (explain, test, library, generate). It does not instruct the agent to read local files, environment variables, or external endpoints. One functional ambiguity: the SKILL.md does not state which regex flavor/engine (PCRE, JavaScript, Python, etc.) to use, so matching/explanation behavior may vary depending on the agent's runtime. Also the metadata block in SKILL.md contains stray punctuation (trailing commas) suggesting it is documentation-only.
Install Mechanism
No install spec and no code files; nothing will be downloaded or written to disk by the skill itself. This is the lowest-risk install pattern.
Credentials
No environment variables, credentials, or config paths are requested. The skill's described functionality does not justify additional secrets or system access.
Persistence & Privilege
always is false and the skill is not asking for persistent or elevated privileges. It is user-invocable and can be invoked autonomously (platform default) but there are no other privileged behaviors requested.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install regex-playground - After installation, invoke the skill by name or use
/regex-playground - Provide required inputs per the skill's parameter spec and get structured output
