💡 The Core Thesis: Bridging Intent vs. Effect
"Dry-run sandboxing is the piece that stands out. Guardrails and masking catch known bad patterns, but a sandbox shows what an agent's query would actually do before production. That gap between intent and effect is where most agent database incidents begin."
When an AI coding agent acts on your database, static AST rules and regex patterns only catch known bad syntax (like DROP TABLE or WHERE 1=1). They cannot catch semantically plausible queries where the effect completely diverges from the user's intent:
┌──────────────────────────────────────┐ ┌────────────────────────────────────────────────────────────┐
│ AGENT'S STATED INTENT │ │ AGENT'S EMITTED SQL │
│ "Update avatar for user #402" │ ──► │ UPDATE users SET role = 'admin' WHERE id = 402; │
│ Expected Effect: 1 row, non-sens col │ │ Simulated Effect: Privilege escalation to superadmin! │
└──────────────────────────────────────┘ └────────────────────────────────────────────────────────────┘
