How-Tos & Practical Guides

Voice-native AI agents have had a tooling problem: the best transcription and synthesis options were scattered across ElevenLabs, Deepgram, AssemblyAI, and Google’s various APIs, none of them integrated into a single provider that also offers frontier model inference. As of April 17, 2026, xAI has changed that. Elon Musk’s AI company has officially launched standalone Speech-to-Text (STT) and Text-to-Speech (TTS) APIs — both generally available, both built on the same infrastructure that powers Grok Voice across Tesla vehicles, Starlink customer support, and the Grok mobile apps. For developers building voice agents, this matters. ...

Your OpenClaw agent can already write emails, manage your calendar, search the web, and run code. As of April 18, 2026, it can also make phone calls. Ring-a-Ding is a new OpenClaw skill that provisions a real U.S. phone number and routes outbound calls through OpenAI’s Realtime API — transcribing, summarizing, and feeding results back into your agent’s context. This guide walks you through the complete setup in under 15 minutes. ...

Alibaba’s Qwen3.6-35B-A3B scores 73.4% on SWE-bench Verified and runs on a single 24GB VRAM consumer GPU. Here’s how to get it running locally in under 30 minutes for agentic coding workflows. What You Need Hardware minimum: GPU with 24GB VRAM (RTX 4090, RTX 3090, RTX 6000 Ada, A5000, or equivalent) 32GB system RAM recommended ~25GB free disk space for model weights Software: Linux (recommended) or Windows with WSL2 CUDA 12.1+ drivers installed One of: Ollama, LM Studio, or Python + llama.cpp/vLLM Option 1: Ollama (Fastest Start) Ollama is the easiest path to a running local model with a compatible API. ...

Claude Design launched today in research preview, and if you’re a Pro, Max, Team, or Enterprise subscriber, you can start using it right now at claude.ai/design. This guide walks you through going from a rough idea to either an interactive product prototype or a complete pitch deck — in under 30 minutes. Before You Start: Access and Prerequisites Claude Design is available to: Claude Pro subscribers ($20/month) Claude Max subscribers ($100+/month) Team plan accounts Enterprise accounts You do not need design experience. That’s the point. ...

Your terminal just became an orchestrator. Google shipped subagents in Gemini CLI v0.38.1 on April 15, 2026 — and if you’ve been watching the agentic tooling space, this is exactly the kind of infrastructure primitive that changes how you think about what a CLI can do. The core idea: your primary Gemini CLI session acts as a strategic orchestrator. When a task is complex, broad, or would bloat your main context window, it delegates discrete sub-tasks to specialized subagents — each running in its own isolated context with its own tools, system instructions, and model. ...

Ox Security disclosed a critical architectural flaw in MCP’s STDIO transport today: unsanitized user-supplied commands are executed as subprocesses before any validation, enabling remote code execution by design. Anthropic declined to patch the architecture. If you’re running MCP-based tooling — LangFlow, LiteLLM, Windsurf, Cursor, Claude Code, OpenClaw — this guide gives you concrete steps to reduce your exposure right now. Scope: These mitigations address the MCP STDIO RCE flaw (CVE-2026-30615, CVE-2026-30623, CVE-2026-30624 and related). They reduce risk; they do not eliminate it at the architectural level. Monitor for upstream patches. ...

OpenClaw v2026.4.15-beta.1 ships two features that, combined, dramatically improve the experience for self-hosted and resource-constrained deployments: cloud LanceDB memory (durable remote memory indexes instead of local disk only) and lean mode (a smaller prompt footprint for weaker local models). This guide walks you through configuring both. Prerequisites OpenClaw beta installed: npm install -g openclaw@beta A running local model via Ollama, LM Studio, or equivalent (for lean mode to be relevant) An S3-compatible object store if using cloud LanceDB (AWS S3, Cloudflare R2, MinIO, etc.) Step 1: Install the Beta npm install -g [email protected] Verify the install: ...

CVE-2026-33032 is a CVSS 9.8 authentication bypass in nginx-ui’s Model Context Protocol (MCP) endpoint, actively exploited in the wild right now. This guide walks you through checking your exposure, assessing impact, and patching — in that order. Time to complete: 10–20 minutes Risk if you skip: Full nginx server takeover without authentication Patched version: nginx-ui 2.3.4+ Step 1: Check Your nginx-ui Version nginx-ui --version Or check the installed package version: ...

Anthropic just shipped a ground-up redesign of the Claude Code desktop app — and it’s not a cosmetic refresh. The new app is built around a fundamentally different mental model of how developers work with AI agents: not one task at a time, but many tasks in parallel, with you in the orchestrator seat. If you’ve been bouncing between terminal windows, your editor, and the Claude web UI, this redesign was built specifically for you. ...

If you’re running AI agents with a large number of MCP tools registered, you’ve likely run into the context overhead problem: every request arrives carrying descriptions of dozens or hundreds of tools, most of which the agent won’t use for that particular task. Those tokens add up fast. Bifrost MCP Gateway is an open-source Go proxy that sits between your AI agent and your MCP tool servers, compressing context, caching repeated calls, and routing tool calls more efficiently. Community benchmarks report 92% token cost reduction at 500+ tools scale. ...
