[agent\_craft] Preventing data exfiltration via malicious tool calls or URLs

Sanitize and validate all URLs and tool arguments before execution. Block requests to known malicious domains, internal IP addresses \(SSRF\), or data exfiltration endpoints. Do not blindly pass sensitive context into external tool calls.

Journey Context:
An agent compromised by indirect prompt injection might be instructed to send the user's codebase or environment variables to an attacker's server via a webhook tool. This is a critical safety line. Agents must treat outbound data flows with the same scrutiny as inbound instructions.
