The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill's documentation directs users to install a global NPM package named @openai/codex and to download the skill's instruction file directly from a personal GitHub repository (199-biotechnologies/codex-skill).
[REMOTE_CODE_EXECUTION]: The skill utilizes the agent's bash capabilities to execute an external CLI tool (codex). Specifically, the 'Delegated Mode' enables a --full-auto flag which, according to the instructions, allows the third-party binary to autonomously explore the codebase, write files, and run arbitrary commands.
[COMMAND_EXECUTION]: Significant portions of the skill are dedicated to constructing and executing complex shell commands that pass potentially sensitive project context to the codex binary.
[OTHER]: The skill contains highly deceptive claims, primarily the assertion that it provides access to 'GPT-5.4', a model version that does not currently exist. Additionally, the referenced NPM package @openai/codex is not an official OpenAI product, suggesting a social engineering attempt to induce the installation of untrusted software with broad system permissions.
