Resources & Tools

OFFICE ENGINE

Office Engine embeds DOCX, XLSX, and PPTX viewing and editing in a browser through React or a web component. Progressive loading, Web Worker parsing, and virtualized views handle large files, while saves regenerate edited parts and preserve the original bytes elsewhere.

DJS

djs is a JavaScript and TypeScript engine written in Rust for agent-generated scripts running in a WebAssembly sandbox. It keeps the entire VM state in one byte array, allowing execution to pause between instructions, snapshot while waiting for tools, and resume elsewhere. The focused runtime deliberately omits features such as ES modules, Intl, and a JIT.

THREE-LIVE

Three-Live compiles a declarative subset of Three.js into GLB and USDZ assets for web, Android, and Apple rendering pipelines. It runs generated scripts with execution timeouts and geometry quotas, then hands the assets to platform-specific viewers. The Apache-licensed project is in Developer Preview and is not an officially supported Google product.

CRASHTEST

Crashtest runs adversarial security tests against a JavaScript app's real route handlers entirely in-process, so it never opens a socket or needs a live server. Its built-in campaigns cover identity-spoofing headers, prototype pollution, cross-tenant ID enumeration, leaked secrets, and cost-amplification abuse, and every attack ends in a verdict of REFUSED, EXPLOITED, or BOUNDED (an accepted risk with a named owner). It plugs into Hono, Express, and Fastify, and its GitHub Action fails CI only on a new exploit or a regression, never on risks the team already accepted.

SAFEAGENTS

safeagents is a local proxy that sits between a coding agent and its model API and checks each tool call before the harness runs it. It blocks calls to undeclared tools and calls that reach hosts nobody mentioned in the conversation, and it runs atif-scan detectors that catch reads of /proc/1/environ or curl --noproxy. Ambiguous calls can go to an optional judge model that sees only the user's prompt, the call, and the findings, never the agent's reasoning, and it works with any harness that accepts a custom base URL, including Claude Code, OpenCode, and Hermes.

FLOCI

Floci is a free, open-source local AWS emulator for development, testing, and CI that works without a cloud account or auth token. It supports standard tools like Terraform and the AWS CLI, and Lambda or RDS workloads run in real Docker containers for higher fidelity than mocks. The project also acts as a drop-in replacement for LocalStack.

AGENT-DESKTOP

Agent-Desktop is a CLI that enables AI agents to see and operate desktop applications on macOS, Windows, and Linux through the OS accessibility tree. It reads the accessibility tree as JSON, allowing agents to interact with elements without using screenshots or pixel matching.
