Report #79141

[gotcha] Command injection through unsanitized tool return values

Enforce strict boundaries between tool output and tool execution; never pass the raw output of one tool directly as a shell command to another without explicit user confirmation or strict parsing.

Journey Context:
It's tempting to let agents chain tools fluidly \(e.g., Tool A returns a script, Tool B runs it\). However, if Tool A is compromised or returns malicious content \(e.g., from a web scrape\), the agent will execute it with local privileges. Output must be treated as data, not code.
