These packages give you a middleware-based fault injection engine that sits between your agent and its tools, injecting failures like latency spikes, rate limits, and malformed output to test whether your circuit breakers, confidence gates, and fallback trees actually work. You'd adopt them to validate agent reliability under realistic failure conditions before they hit production. The most distinctive thing is the transparent interceptor pattern — adapters for LangChain, LlamaIndex, and Vercel AI SDK wrap your existing tool calls without modifying agent code, while a declarative YAML/JSON scenario system with probability-based fault selection and hot reloading lets you change failure modes at runtime.
Framework adapters for injecting fault-tolerance testing into LangChain, LlamaIndex, Vercel AI SDK, or any custom agent with a tool-call interface, using a shared interceptor pattern that wraps tools without modifying agent code. Each adapter exports a framework-specific wrapper (e.g., a tool wrapper for LangChain, a tool spec wrapper for LlamaIndex) that pairs with the `@reaatech/agent-chaos-core` engine at runtime.
A CLI that validates, generates, and runs chaos engineering scenarios for AI agents, providing `init`, `generate`, `validate`, and `run` commands for managing fault-injection test scenarios defined in YAML or JSON.
Middleware-based fault injection engine for agent systems that intercepts tool calls and injects latency, timeout, malformed output, token exhaustion, and other failure modes via a single `engine.intercept()` call, with scenario-driven YAML/JSON configuration, probability-based fault selection, and seeded randomness for reproducible testing.
End-to-end test suite that validates the full agent-chaos pipeline—scenario loading, schema validation, fault injection, engine event recording, CLI execution, and cross-package integration—against mock agent implementations.
Structured logging, metrics collection, OpenTelemetry tracing, and report generation for chaos engineering experiments, exposed as a set of classes (`MetricsCollector`, `Tracer`, `ReportGenerator`) that consume events from `@reaatech/agent-chaos-core`.
A scenario loader and validator for the agent-chaos fault injection toolkit that parses YAML and JSON scenario files, validates them against a JSON Schema, supports composition via `extends` with circular reference detection, and provides hot-reloading via file watching. Exports `ScenarioLoader` and `SchemaValidator` classes, plus a `createScenarioLoader` factory function; depends on `yaml`, `ajv`, and `ajv-formats` at runtime.
