Full Analysis
- [DYNAMIC_EXECUTION]: The skill instructs the agent to use the
mcp__node_repl__jstool to dynamically import the@oai/skyruntime usingawait import("@oai/sky"). This pattern allows for the execution of arbitrary code within the Node.js environment.- [COMMAND_EXECUTION]: The instructions require the agent to send Javascript code as single-line strings to themcp__node_repl__jstool to interact with the computer use runtime.- [PRIVILEGE_ESCALATION]: The skill is designed to grant the agent high-privilege capabilities, including the ability to operate desktop application UIs, use browsers like Safari or Chrome, perform click and type actions, and capture screenshots of the user's screen.- [INDIRECT_PROMPT_INJECTION]: The agent is directed to read a local file (~/.codex/plugins/cache/openai-bundled/computer-use/<version>/skills/computer-use/SKILL.md) and treat its content as authoritative instructions. This creates a vulnerability surface where the agent's behavior is governed by external, potentially mutable local data. - Ingestion points: Local path
~/.codex/plugins/cache/openai-bundled/computer-use/<version>/skills/computer-use/SKILL.mdidentified inSKILL.md. - Boundary markers: Absent; the agent is explicitly told the external skill is 'authoritative'.
- Capability inventory: Includes arbitrary Javascript execution via
nodeRepl.write, UI automation, and desktop screenshotting. - Sanitization: Absent; the agent is instructed to read the file content directly before performing computer-use work.
