Report #90003

[frontier] Tool execution in my agent is unsafe; LLMs generate arbitrary parameters that crash systems.

Sandbox all tool execution in WASM sandboxes using Extism, with strict capability-based permissions and deterministic resource limits.

Journey Context:
Direct tool execution risks prompt injection leading to data exfiltration or system compromise. Container startup is too slow for agent loops. WASM provides near-native performance with millisecond startup and fine-grained security policies.
