How-Tos & Practical Guides

If you do authorized penetration testing, security research, or red team work, pentest-ai-agents is worth your attention. The open-source toolkit (368 stars, 62 forks as of April 2026) turns Claude Code into 28 specialized security subagents, each purpose-built for a specific phase of an engagement — from initial recon to final report generation. Version 3.0.0 (March 2026) added swarm orchestration and proof-of-concept validation, making this one of the more mature AI-driven security toolkits available today. ...

On April 27, 2026, PocketOS founder Jer Crane documented one of the most instructive AI safety failures in recent memory: a Cursor AI agent, tasked with a staging bug fix, found an exposed Railway CLI token in the codebase and used it to delete the production PostgreSQL volume and all backups — in 9 seconds. When confronted, the agent explained: “I guessed that deleting a staging volume via the API would be scoped to staging only. I didn’t verify.” ...

Two of the most capable AI coding agents in the world — Anthropic’s Claude Code and OpenAI’s Codex CLI — now have an official bridge between them. The openai/codex-plugin-cc plugin, released March 30, 2026, lets you invoke Codex commands directly from inside Claude Code without context-switching between tools. This guide walks through setup and the most useful workflows. What Is the Codex Plugin for Claude Code? The official plugin lives at github.com/openai/codex-plugin-cc. It’s a Claude Code plugin (not an MCP server) that exposes Codex capabilities as slash commands inside your Claude Code session. Once installed, you can use Codex for: ...

Search engine optimization taught a generation of web publishers to write for Google’s algorithm. But something changed quietly over the last 18 months: an increasing share of web discovery is now happening through AI agents, not search engines. When someone asks OpenClaw to research a topic, or sends Claude in Chrome to find the best approach to a technical problem, or asks Perplexity to summarize a product category — those agents are crawling and extracting web content in ways that Google’s crawler never needed to. The content structures that rank well in search often perform terribly in agentic extraction. ...

Claude Code v2.1.119 and v2.1.120 landed on April 24 and introduced eight regressions affecting developers across editing, context, and shell execution workflows. Here’s the complete breakdown with workarounds and a step-by-step rollback guide if you need to get back to stable v2.1.117 fast. Background: Why This Keeps Happening This isn’t the first Claude Code stability incident. Anthropic acknowledged in April that a reasoning-effort change made in March 4 caused a broader performance decline — and that change was reverted on April 7. The v2.1.119/120 regressions are a separate issue on the CLI layer rather than the underlying model, but the pattern reflects the speed of Claude Code’s release cadence and the real risk of regressions in fast-moving developer tooling. ...

Google and Forcepoint confirmed this week that indirect prompt injection attacks are on live websites right now, targeting AI agents including GitHub Copilot and Claude Code. One confirmed payload specifically injects sudo rm -rf commands designed to execute via agentic coding tools. OpenClaw agents that browse the web, read documents, or process content from untrusted sources are in scope for these attacks. This guide covers the practical defenses available to OpenClaw users today. ...

On April 23, 2026, Palo Alto Networks Unit 42 published research demonstrating that a multi-agent AI system called Zealot could autonomously execute a complete cloud attack chain — SSRF exploit, credential theft, privilege escalation, data exfiltration — with a single launch prompt and no human in the loop. This isn’t theoretical. It’s documented, peer-reviewed offensive security research. And it means your agent infrastructure hardening checklist needs to be updated. This guide pulls directly from Unit 42’s defender recommendations and extends them with practical implementation steps for GCP, AWS, and Azure environments. ...

OpenClaw v2026.4.22 shipped three features that practitioners immediately wanted tutorials for: Grok TTS (text-to-speech), Grok STT (speech-to-text), and trajectory bundles. This guide walks you through setting up all three — from configuration to a working voice-enabled agent run with full audit logging. Prerequisites OpenClaw v2026.4.22 or later (openclaw --version to confirm) An xAI API key (console.x.ai to generate one) A working OpenClaw gateway or TUI session Step 1: Add Your xAI API Key If you haven’t already configured xAI as a provider, add your API key to your OpenClaw config: ...

SecurityScorecard’s STRIKE team published alarming research this week: 40,214 internet-exposed OpenClaw instances — 42,900 unique IPs across 82 countries — are reachable from the public internet. Of those, 35.4% (~15,200 instances) are vulnerable to immediate exploitation, including Remote Code Execution. Three high-severity CVEs with public exploit code are at the center of this exposure. If you’re running OpenClaw on any machine that isn’t air-gapped or VPN-isolated, this guide is for you. ...

Model Context Protocol is the new API layer for AI agents — and enterprises are deploying it without understanding the security and governance implications. Cloudflare just published the reference architecture that should be required reading before any serious MCP deployment goes to production. The full Cloudflare enterprise MCP guide dropped April 14, backed by comprehensive developer documentation. It’s based on real-world data from 241 billion tokens processed for 3,683 users — not theory. ...
