Full Analysis
- [REMOTE_CODE_EXECUTION]: The skill instructs users to install the steward CLI by fetching a script from the author's official repository and piping it to the bash shell (
curl -fsSL https://raw.githubusercontent.com/Arenukvern/skill_steward/main/install.sh | bash). While this is the intended setup method from the vendor, it represents a remote script execution pattern.\n- [COMMAND_EXECUTION]: The skill requires the execution of various command-line tools, includingsteward,dart, andnpx, to perform repository maintenance, validation, and contract checks.\n- [DYNAMIC_EXECUTION]: The skill facilitates the compilation and execution of local tools, such as usingdart compile exefor binary creation anddart runfor executing local packages, which are standard developer workflows for this harness.\n- [INDIRECT_PROMPT_INJECTION]: The skill processes multiple untrusted repository files, which could contain malicious instructions designed to influence the agent's behavior. 1. Ingestion points: The agent reads files such assteward.yaml,package.json,Cargo.toml, and other metadata files within the repository. 2. Boundary markers: There are no explicit delimiters or instructions provided to the agent to treat the content of these files as data only. 3. Capability inventory: The skill possesses capabilities to execute shell commands, run local scripts, and perform network operations during installation. 4. Sanitization: There is no mention of sanitization or strict schema validation performed on the contents of these files before the agent acts upon them.
Recommendations
- HIGH: Downloads and executes remote code from: https://raw.githubusercontent.com/Arenukvern/skill_steward/main/install.sh - DO NOT USE without thorough review
