Report #80210

[frontier] Agent remembers how to use dangerous tools but forgets safety guardrails \('always ask before deleting'\)

Convert guardrails into mandatory binary tool calls \(e.g., \`verify\_human\_consent\(tool\_name='delete', resource\_id='xyz'\)\` that must return \`\{'approved': True\}\` before executing the actual tool.

Journey Context:
LLMs maintain 'tool schemas' in a separate, structurally reinforced attention space because they map to JSON function definitions. Text-based rules \('don't delete without asking'\) live in the general semantic space which suffers from higher drift. The 'Constraint-as-Tool' pattern leverages the fact that agents have stronger 'muscle memory' for tool-calling protocols than for policy adherence. By making safety checks a hard dependency in the tool graph, you create a compile-time error \(tool call failure\) rather than a runtime policy violation. This became standard in 2026 agent safety engineering.
