Chainable deadline logic for LangChain

Use `calculate_statute_deadline` to kick off your legal reasoning chain. Feed the output directly into subsequent nodes to determine the base filing window for any state-specific claim. Your agent builds a logical sequence by passing results through your LangGraph pipeline. This approach removes manual data entry and ensures the math stays consistent across every step of your workflow.

Automated tolling adjustments

Trigger `check_tolling_impact` when your agent encounters evidence of suspended limitations. It processes the incident data to verify if external factors have moved your filing target. LangSmith tracing lets you inspect exactly how these adjustments modify your final output. You see the logic path, ensuring the agent doesn't miss a critical statutory extension.

Contextual discovery rule application

Invoke `evaluate_discovery_rule` within your LangChain agent when the initial incident date doesn't match the discovery of harm. It re-calculates the clock based on the actual awareness of the injury. This tool acts as a conditional branch in your chain. By integrating this into your agentic flow, you create a robust system that handles complex litigation scenarios without hard-coded rules.
