The Agent Skills Directory

[DYNAMIC_EXECUTION]: scripts/on_serverless/emr_serverless_submit_cli.py uses the __import__ function to dynamically load task modules from the serverless SDK based on hardcoded mapping lists. This enables the skill to handle various job types like Spark and Ray through dynamic dispatch.
[EXTERNAL_DOWNLOADS]: The skill installs a local Python wheel asset (assets/libs/python_serverless-1.0.3.4.1-py3-none-any.whl) using pip install via the scripts/bin/install_serverless_sdk.sh script. This package is a ByteDance-developed SDK required for EMR Serverless operations.
[COMMAND_EXECUTION]: The skill provides CLI-style Python scripts that act as wrappers for Volcano Engine OpenAPI endpoints. These allow the agent to manage cluster nodes, submit big data jobs, and update service configurations.
[INDIRECT_PROMPT_INJECTION]: The skill ingests external data from EMR diagnostic tools and logs, which represents a potential attack surface.
Ingestion points: Diagnostic reports and session histories fetched by scripts/emr_agent/expert.py and scripts/emr_agent/emr_agent_manager.py.
Boundary markers: None identified; external data is integrated into the output stream without specific delimiters.
Capability inventory: Cluster resource management, job execution (Spark/Ray), and file management within the ./tmp directory.
Sanitization: Content from external APIs is displayed directly; no specific sanitization for malicious prompts in logs was observed.
