Stacklink

Overview

Stacklink is the integration, knowledge, and execution boundary for AI agents.

Stacklink connects tools, knowledge, accounts, events, and workbenches for AI agents. It is the backend boundary for external provider integrations and verified knowledge packs, so your app keeps only its own product reasoning and user experience.

The boundary

Stacklink owns external provider accounts, provider toolkits, tool search, tool execution, knowledge packs, verified evidence receipts, triggers, polling, webhooks, jobs, artifacts, and raw provider events. Your consumer app owns final answer generation, product policy, and product-specific UI when using the tool integrations. With Bots, Stacklink also runs the configured model/tool loop and produces the answer. Your application supplies its UI.
