ToolSuture: Recovering Agent Capability When APIs Change

说明与用途

ToolSuture 在 API 变更后恢复代理功能，无需重新部署代理，利用 Gemini 进行语义推理并进行独立验证。

问题

Agents break when underlying API contracts change, even if the agent logic remains correct.

结果

ToolSuture restored the original shipment agent’s capability after a provider contract upgrade without modifying the agent code, achieving 0 bytes changed and 0 execution attempts in dangerous scenarios.

工作流

• Freeze deployed agent and capture original mission
• Detect API change and obtain new tool contract
• Observe mission, old and new contracts, and runtime evidence
• Diagnose semantic equivalence using Gemini 3.6 Flash
• Apply policy to decide repair or refusal
• Plan bounded compatibility repair
• Validate repair against new contract
• Replay original mission with repaired environment
• Verify success through independent evidence checks
