Report #56778

[frontier] Tool execution compromises agent security and context integrity

Spawn ephemeral sandboxed processes \(containers or WASM\) per tool invocation with mandatory output validation gates—tool results must pass schema validation and content safety checks before reintegration into agent context, preventing prompt injection and context pollution.

Journey Context:
Production agents executing arbitrary tools face injection attacks where tool outputs \(web pages, API responses\) contain malicious instructions. The emerging pattern is treating every tool call as a potential attack vector: execute in isolated ephemeral environments \(Docker containers, gVisor, WASM\) and validate outputs against strict schemas before the agent 'sees' them. This mirrors security patterns from browser sandboxing applied to LLM tools. Prevents 'tool output poisoning' that bypasses prompt injection defenses.
