tool calls

Self-hosted LLM proxy that redacts personal data before requests reach model providers, including inside tool-call arguments and multimodal content. It supports OpenAI-compatible clients, runs locally with zero telemetry, and uses Presidio plus an optional privacy filter for broader PII and secret detection.

Open-source SDK for governing AI agent tool calls before side effects happen, with policy enforcement, approval flows, audit logs, and local execution.

Open-source execution runtime for production agents. It records tool and LLM calls as durable steps, supports resume after interruption, and lets teams allow, deny, or approve steps with human oversight.

An open-source tool that screens AI agent tool calls and tool results before they are used. It works as an MCP proxy plus hooks adapter, with policy-based decisions, shadow mode, and local logging.

A Ruby gem that encodes the Vercel AI SDK Data Stream protocol for Rails and Rack backends, so Ruby apps can stream text, reasoning, tool calls, and data parts to useChat/useObject.

A technical case study on reducing token usage in a coding agent, including a model-free harness, wire-level measurement, and several concrete optimizations that cut a long run from 1.04M to 517k tokens.
