Full Analysis
  • [REMOTE_CODE_EXECUTION]: The skill explicitly suggests executing code from https://opencode.dev/install by piping it directly to bash (curl -fsSL ... | bash). This is a high-risk pattern as it allows for arbitrary code execution from an untrusted external source without verification.
  • [COMMAND_EXECUTION]: The skill relies on the bash tool to interact with the local environment, including running the opencode CLI and managing process lifecycles, which poses a risk if these commands are manipulated by external input.
  • [INDIRECT_PROMPT_INJECTION]: The skill ingests data from the output of the OpenCode process which could be influenced by external project data or attacker-controlled prompts.
  • Ingestion points: Data is ingested via process.poll in SKILL.md.
  • Boundary markers: There are no boundary markers or instructions to the agent to ignore embedded commands within the tool output.
  • Capability inventory: The skill has access to bash, process.write, and process.kill as seen in SKILL.md.
  • Sanitization: There is no evidence of output filtering or sanitization before the data is processed by the agent.
Recommendations
  • HIGH: Downloads and executes remote code from: https://opencode.dev/install - DO NOT USE without thorough review
  • AI detected serious security threats
