Description
One-click Gene comparison and evaluation for Rotifer Protocol. Import from ClawHub Skills, local files, or build from scratch — automatically compile, match...
Usage Guidance
This skill appears to do what it says (compile Genes, submit to Arena, report results) but there are two practical inconsistencies to check before installing:
- The SKILL.md requires npx and the @rotifer CLI (it runs commands like `npx @rotifer/playground` and `rotifer compile`), but the skill metadata lists no required binaries. Make sure your environment has Node.js/npx or otherwise be prepared for npx to fetch packages at runtime.
- The agent will read local files (phenotype.json) and can write Markdown reports into your project (arena-reports/...md) when you confirm 'save'. Ensure you trust the rotifer packages it will fetch (verify the npm package and repository links) and that writing those files in the project workspace is acceptable.
If you want higher assurance, ask the publisher to: (1) update metadata to declare required binaries (node/npx) and any expected network endpoints, (2) point to a specific, pinned rotifer release or repository, and (3) document any remote servers the CLI communicates with. If you cannot verify those, treat the skill as untrusted in sensitive projects.
Capability Analysis
Type: OpenClaw Skill
Name: rotifer-arena
Version: 1.0.3
The rotifer-arena skill bundle is a developer tool designed to benchmark and compare AI agent capabilities (referred to as 'Genes') using the Rotifer Protocol. It provides structured instructions for an AI agent to wrap, compile, and evaluate skills using the `@rotifer/playground` CLI via `npx`. The workflow includes automated opponent matching, Arena submission, and the generation of detailed Markdown reports. The skill includes safety constraints, such as requiring user confirmation for cloud publishing and file saving. No malicious patterns, data exfiltration, or harmful prompt injections were identified; the code and instructions are entirely consistent with the stated purpose.
Capability Assessment
Purpose & Capability
The name/description (Gene/Arena comparison) align with the SKILL.md workflow: wrapping/importing Genes, compiling, running arena battles, and producing reports. However, the published metadata claims no required binaries or env vars while the instructions clearly rely on npx and the @rotifer CLI. This metadata omission is inconsistent and should be corrected.
Instruction Scope
Instructions are narrowly scoped to Rotifer operations (rotifer compile, arena submit, list, wrap) and report generation. They instruct the agent to read phenotype.json (local project data) when needed and to write Markdown reports to <project>/arena-reports/*.md after a user 'save' confirmation — both relevant to the stated purpose but involve local filesystem access that users should be aware of.
Install Mechanism
There is no install spec (instruction-only), which is lower risk. However, the SKILL.md expects npx usage (e.g., npx @rotifer/playground and npx @rotifer/mcp-server). npx will fetch and run code from the npm registry at runtime; this dependency is not captured in the skill metadata. That mismatch is worth noting.
Credentials
The skill declares no required environment variables or credentials and the instructions do not request secrets. This is proportionate to the advertised functionality.
Persistence & Privilege
always is false and autonomous invocation is allowed (the platform default). The skill's workflow writes reports to the project workspace when the user explicitly confirms 'save'; this is reasonable for its purpose and does not request elevated platform privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install rotifer-arena - After installation, invoke the skill by name or use
/rotifer-arena - Provide required inputs per the skill's parameter spec and get structured output
