Full Analysis
- [COMMAND_EXECUTION]: The skill uses local Node.js scripts to automate development tasks by spawning system processes. Specifically,
runtime/serve.mjscan launch code editors to open files at specific line numbers, andruntime/shoot.mjsexecutes headless browser commands to capture UI screenshots. These executions are core to the skill's utility and include safeguards such as directory-restricted path resolution and argument escaping. - [INDIRECT_PROMPT_INJECTION]: The skill provides a mechanism for ingesting untrusted data in the form of reviewer feedback, which creates a surface for indirect prompt injection.
- Ingestion points: Reviewer comments are gathered via
runtime/html-mark.jsand presented to the agent as instructions for code modification. - Boundary markers: The feedback format uses specific metadata tags to delineate reviewer notes from element selectors and snapshots.
- Capability inventory: The agent possesses the ability to modify project source code and execute local scripts based on the ingested instructions.
- Sanitization: There is no automated sanitization of the reviewer-provided text, meaning a malicious comment could attempt to manipulate the agent into performing unauthorized file or system operations.
