# `ReqManagedAgents.Providers.BedrockAgentCore.HarnessSpec`
[🔗](https://github.com/cash-mckeeman/req_managed_agents/blob/v0.12.0/req_managed_agents/lib/req_managed_agents/providers/bedrock_agent_core/harness_spec.ex#L1)

Typed CreateHarness spec assembled by `BedrockAgentCore.build_spec/2`. `environment` is the opaque, provider-verbatim `Environment.Spec.config` passthrough (env vars live nested inside it, as the AWS API shapes them — there is no separate indexed field).

# `t`

```elixir
@type t() :: %ReqManagedAgents.Providers.BedrockAgentCore.HarnessSpec{
  environment: map() | nil,
  execution_role_arn: String.t(),
  model: String.t() | map() | nil,
  name: String.t(),
  system_prompt: String.t(),
  tools: [map()]
}
```
