guardrail-chain · packages

Provides a framework for orchestrating sequences of LLM guardrails with built-in budget management, circuit breaking, and retry logic. It exports the `GuardrailChain` orchestrator and `ChainBuilder` class, requiring the `@reaatech/guardrail-chain-observability` package for logging and telemetry.

Loads and validates Guardrail Chain configurations by merging JSON or YAML files with environment variable overrides. It provides utility functions that return validated configuration objects using Zod schemas.

Provides a collection of thirteen pre-built input and output guardrail classes for the `@reaatech/guardrail-chain` framework. These classes implement the `Guardrail` interface to perform tasks like PII redaction, prompt injection detection, and content moderation using deterministic regex-based logic.

Provides pluggable interfaces for structured logging, metrics collection, and distributed tracing within the Guardrail Chain framework. It exposes global getter and setter functions to inject custom implementations for these observability subsystems.
