LangChain features
- Build agents fast. Start with proven patterns, customize harness, context, memory and model choice.
- Trace-based testing. Debug runs with step-by-step tracing and query complex traces instantly.
- Managed deployments. Deploy long-running agents with serverless or dedicated sandboxes and 30+ endpoints.
- Production monitoring. Online evals, dashboards and alerts track quality, cost, latency and errors.
- Feedback loop engine. Automatically detect issues, diagnose root causes and feed fixes back into evals.
- Governance controls. Enforce cost limits, data redaction and human approval via LLM Gateway.
PIC Standard: Provenance & Intent Contracts features
- Action Proposal schema. Agents emit a JSON contract describing intent, impact, provenance and evidence before each tool call.
- Deterministic evidence verification. SHA-256 resolvable artifacts are validated; unverifiable evidence blocks high-impact actions.
- Fail-closed security model. If verification fails, the action is automatically rejected to prevent unsafe operations.
- CLI and SDK integrations. Provides a command-line tool and drop-in integrations for LangGraph and MCP servers.
- Cryptographic signing. Supports signing of contracts and API attestations for trusted provenance.
- Risk classification. Allows agents to label impact classes such as money, privacy, compute or irreversible actions.
