Documentation

You’re in the simian-agent reference docs. The site root has the marketing pitch; this section is the reference.

Start here

Brand new?Getting started walks from make all through your first directed-chaos fault and your first autonomous-mode plan against an Online Boutique deployment.

Installing in-cluster?Deploying with Helm covers the chart install patterns and the recommended overlay.

Picking which chaos engine to use?Using the chaos engines covers the directed and autonomous patterns for chaos-mesh, network-policy, and envoy-fault — including which one to reach for on which kind of cluster.

Pointing it at GKE?GKE bring-up covers the Dataplane V2 and Autopilot constraints, and how to measure which fault kinds actually land on your cluster.

Hit something weird?Known limitations collects the GKE Dataplane V2 NetworkChaos question, the Envoy injection vs gRPC probe interaction, and other gotchas worth knowing about before you debug.

Getting things done

Concepts and design

  • Design — architecture: Fault Executor chokepoint, LLM Provider contract, chaos drivers, MCP surface, deployment topology.
  • Requirements — scope, operating modes, deployment postures, the R-* requirements catalog.
  • Roadmap — phased development plan; what’s shipped, what’s next.
  • DPv2-compatible chaos engines — why we built network-policy and envoy-fault, and what they replace.

Operating

Working on Simian

  • Contributing — how to file issues, structure PRs, and keep the recommended-defaults overlay honest.

Getting started

From clone to your first chaos fault in under 10 minutes.

GKE bring-up

Pointing Simian at a real GKE cluster, and finding out which faults actually land on it.

Design

Architecture: Fault Executor chokepoint, LLM Provider contract, chaos drivers, MCP surface.

Requirements

Scope, operating modes, deployment postures, and the R-* requirements catalog.

Roadmap

Phased development roadmap — what’s shipped, what’s next.

Eval substrate plan

Plan for turning Simian into the fault plane and ground-truth source for evaluating the go-steer agentic SRE stack.

DPv2-compatible chaos engines

Why we ship network-policy + envoy-fault engines for GKE Dataplane V2 clusters.

Deploying with Helm

How to install the controller in-cluster via the Helm chart.

Web UI design

Design doc for a single browser surface serving two purposes: live operator dashboard over simian serve, and the eval scorecard over run artifacts.

Using the chaos engines

Directed and autonomous patterns for chaos-mesh, network-policy, envoy-fault, and kube-state.

Efficacy probes

Probes gate Apply so a fault that silently did nothing is never reported as applied.

CLI reference

Every flag on every simian subcommand.

Helm values reference

Every Helm chart value, what it does, and the recommended setting.

Known limitations

Cluster-side gotchas, dataplane caveats, and feature limitations contributors should know about.

Contributing

How to file issues, structure PRs, and keep our chart values overlay honest.
