Tilde is a harness SDK platform designed for quickly building and self-hosting AI agents. The project, developed over a year, aims to provide developers with the desired developer experience, portability, and composability for AI agent creation.

Tilde offers modular components for agents, including Tools for server spin-up and credential management, Chat Kit for integrations with platforms like Slack and GitHub, and Memory for persistent storage and skill registries. These components are cloud-based, centrally managed, and permissioned.

A practical example showcased is a code-review agent. This agent can be triggered on GitHub PRs, securely check out code in a sandbox without exposing credentials, analyze git diffs based on prompts, and provide feedback inline and as a summary. The example demonstrates Tilde's ability to handle the underlying infrastructure, allowing focus on agent logic. The repository provides a deployable example, with configuration options for GitHub and sandbox settings, emphasizing portability.
