About this project
TypeSafe AI System One integration for adk-go, bringing Choice, Score, and Noul primitives to Go agents and workflows with models such as Jev. Provides a typed HTTP client, ADK function tool, classification and routing agent, assessment callbacks, and dynamic context filtering. The client is a temporary bridge until TypeSafe publishes a Go SDK; its API types are generated from TypeSafe's OpenAPI schema. Other providers: adk-go-bedrock · adk-go-ollama · adk-go-kronk.
Quoted from the project's README. Read the full README.
Highlights
- Provides a typed HTTP client with configurable model, timeout, base URL, and inspectable API errors.
- Exposes an ADK function tool where the app fixes questions and the agent supplies only state text.
- Adds a routing agent with confidence threshold, child routes, fallback, and session-state output.
- Ships model and tool assessment callbacks plus a Noul-based history filter with observe mode.
Watch out

Questions about this entry
Short answers drawn from the linked project or page.
It is a temporary bridge with API types generated from the OpenAPI schema, and adapters depend on an evaluator interface so the HTTP client can later be swapped for an official SDK without changing call sites.
No. Retries are disabled by default and opt in with a zero policy covering a small set of statuses with bounded backoff. Transport errors and other statuses are not retried; bound calls with context deadlines.
Low confidence selects the configured fallback child, and API failures stop execution rather than guessing. The full assessment, usage, and routing decision are saved in session state for inspection.
No. Filtering selects original messages for the outgoing request without modifying saved history, retains protected and structural turns, and reports proposed versus applied removals for review.
go get github.com/craigh33/adk-go-typesafe, match the Go version in go.mod, and let typesafe.New(nil) read TYPESAFE_API_KEY. The default model is jev-latest, overridable per client or per request, the default timeout is ten seconds with context cancellation preserved, and errors.As with *typesafe.APIError exposes StatusCode and RetryAfter.
None of the questions. Your application fixes the questions and rubrics at construction and the calling agent supplies only text in the state field; ADK generates the tool's input schema from the Go input type. The tool returns the full structured evaluation and works with any ADK model that supports function tools, including Bedrock, Ollama or Kronk setups.
BeforeModel assesses request messages, AfterModel assesses the model response, and BeforeTool assesses the tool name and arguments. Each needs an application Policy returning a Decision with Block and Reason; a block replaces the response or output, or returns a structured explanation without executing the tool. AfterModel rejects partial responses, so use non-streaming execution.
