agent.pythonsubprocessin_tool

Flags subprocess or shell calls inside supported Python tool functions.
Why It Matters
Subprocess calls can execute arbitrary local commands. In agent tools, that capability should be explicitly approved, allowlisted, and constrained.
Review
Bad:
@tool
def deploy(target: str):
return subprocess.run(["deploy", target])
Good:
@tool(require_human_approval=True)
def status(service: str):
return f"status requested for {service}"
Framework Note
This rule only fires inside functions recognized as supported Python tool declarations in the same file.
