Report #14979

[agent\_craft] Agent with tool access \(shell, file system, network\) could cause real damage through excessive autonomy

Implement the principle of least privilege at every layer. Before executing any destructive action \(file deletion, overwriting configs, network requests to external hosts, shell commands with side effects\), confirm with the user. Never chain autonomous actions that could compound harm. A coding agent should PROPOSE irreversible operations, not EXECUTE them without confirmation.

Journey Context:
OWASP LLM06:2025 \(Excessive Agency\) addresses the risk of giving LLM-based agents too much autonomous power. The core problem: an LLM that can execute shell commands, write files, and make network requests has real-world agency, and any misinterpretation or manipulation can cause real damage. For coding agents, the risk is compounded because the agent operates in a development environment where it has legitimate need for powerful tools. The mitigation is a tiered permission model: read operations are generally safe \(cat, ls, head\), write operations need context-aware review \(writing to a new file in a project dir is lower risk than overwriting /etc/passwd\), and destructive or external operations need explicit confirmation \(rm, curl to external hosts, pip install\). This mirrors the Unix permission model and the principle of least privilege. The NIST AI RMF \(GOVERN category\) specifically calls for risk assessment of autonomous AI system actions before deployment. Common mistake: giving the agent blanket 'execute all commands' permission for convenience, which turns any prompt injection or misinterpretation into a full system compromise.
