jharness-toolkit

Tool registration, Python function adaptation, JSON Schema validation, retry, and circuit breaking for JHarness.

uv add jharness-toolkit

from jharness.toolkit import ToolRegistry, function_tool

ToolRegistry validates tool arguments and, when a tool declares an output schema, the structured_content of every non-failure result. A ToolFailure is a framework error envelope rather than a successful business payload, so its structured content is not checked against the success schema. RetryingTool retries only selected implementation exceptions and requires an idempotent tool when more than one attempt is configured. CircuitBreakingTool is an in-process policy, not a distributed rate limiter.

Installing this distribution installs the exact matching jharness-kernel version.
