Full Analysis
- [METADATA_POISONING]: The skill makes several deceptive claims regarding AI models and performance metrics.
- It references fictitious models such as "GPT-5.2" and "GPT-5.1-thinking" which do not exist in the referenced OpenAI ecosystem.
- It cites specific but unverifiable benchmarks (e.g., "76.3% SWE-bench") for these non-existent models to build false trust.
- [COMMAND_EXECUTION]: The skill provides instructions that create a command injection vulnerability.
- It directs the agent to use syntax like
echo "your prompt here" | codex exec .... If the user input contains shell metacharacters (e.g., backticks or command substitutions), it could lead to arbitrary command execution on the host system. - [METADATA_POISONING]: The skill explicitly instructs the agent to suppress error output by default.
- Using
2>/dev/nullfor all commands hides stderr, which is a concealment tactic. This prevents the user from seeing potential warnings, errors, or evidence of malicious activity generated by the underlyingcodexCLI tool. - [PRIVILEGE_ESCALATION]: The skill encourages the use of high-risk flags.
- It promotes the use of
--sandbox danger-full-accessand--full-auto, which grants the CLI tool broader system permissions and autonomous execution capabilities, increasing the potential impact of a compromise.
