How-Tos & Practical Guides

OpenClaw v2026.4.8 ships an experimental plugin called memory-wiki — a persistent, structured knowledge base that lives across agent sessions. Unlike the flat key-value store of standard memory plugins, memory-wiki organizes knowledge into structured entries and, crucially, detects contradictions when new facts conflict with existing ones. This guide walks you through installing the plugin, configuring it, and using it effectively in your agents. Prerequisites OpenClaw v2026.4.8 or later (run openclaw --version to check) Node.js v20 or later If upgrading from an older install: run openclaw doctor --fix first to migrate legacy config Step 1: Install the Plugin openclaw plugins install memory-wiki This pulls the plugin from ClawHub and adds it to your OpenClaw configuration. The memory-wiki plugin ships as part of the 4.8 release package, so the install should complete immediately without downloading external dependencies. ...

Google’s Agent-to-Agent (A2A) protocol is fast becoming the standard handshake for cross-agent communication in production agentic systems. A new deep-dive from freeCodeCamp — paired with a working GitHub implementation at win4r/openclaw-a2a-gateway — shows exactly how to wire A2A into an OpenClaw plugin so your agent can receive tasks from any A2A-compliant caller. This how-to summarizes the architecture and key implementation steps. For the full guide, see the freeCodeCamp article. What You’re Building An A2A plugin bridge does three things: ...

Three command injection vulnerabilities in Claude Code CLI — CVE-2026-35020, CVE-2026-35021, and CVE-2026-35022 — carry CVSS scores of 9.8 (Critical) and chain together to enable credential exfiltration over HTTP. If you’re running Claude Code in any CI/CD pipeline, this guide walks you through immediate mitigation steps and longer-term hardening practices. This is not optional maintenance. These are exploitable, validated vulnerabilities with confirmed callback evidence. Prerequisites Access to your Claude Code CLI deployment(s) Access to your CI/CD pipeline configurations (GitHub Actions, GitLab CI, Jenkins, or equivalent) Basic shell access to environments where Claude Code runs Permission to update environment variable configurations and outbound network rules Step 1: Check Your Version and Patch Immediately The vulnerabilities are confirmed exploitable on v2.1.91 and earlier. Your first action is to identify and update every Claude Code CLI instance. ...

Google DeepMind’s new research framework maps six categories of “AI Agent Traps” — adversarial techniques embedded in the environment that can hijack autonomous agents without the user or the agent knowing. With content injection attacks succeeding in up to 86% of tested scenarios, this isn’t theoretical risk. This guide walks through each of the six trap categories and gives you concrete, actionable mitigations you can implement today — whether you’re running OpenClaw, a custom LangGraph pipeline, or any other agent framework. ...

LangChain published a framework today for thinking about continual learning in AI agents — and it’s one of the clearest mental models for this problem that’s appeared in the wild. This guide takes that framework and turns it into a practical implementation playbook, with code examples for each layer and decision criteria for choosing between them. The three layers, briefly: agents can learn through context (runtime-injected instructions), storage (external memory), or weights (model fine-tuning). Each has different costs, speeds, and durability characteristics. ...

MolmoWeb is Ai2’s open-source browser agent — 8B parameters, Apache 2.0, no API key required. It scores 78.2% on WebVoyager and beats GPT-4o-based agents on multiple benchmarks. Here’s how to get it running locally. System requirements: GPU with at least 16GB VRAM (for 8B model) or 8GB VRAM (for 4B model) Ubuntu 20.04+ or macOS 12+ (Linux recommended for GPU support) Python 3.10+ Chrome or Chromium browser installed Step 1: Clone the Repository git clone https://github.com/allenai/molmoweb.git cd molmoweb Step 2: Create a Virtual Environment and Install Dependencies python3 -m venv molmoweb-env source molmoweb-env/bin/activate pip install -r requirements.txt The requirements include PyTorch, the Transformers library, Playwright for browser control, and Pillow for screenshot processing. The full install typically takes 3–5 minutes on a good connection. ...

Claude Code Ultraplan offloads your most complex planning tasks to a cloud Opus 4.6 session for up to 30 minutes — while you keep working locally. Here’s how to use it in five steps. Prerequisite: Ultraplan requires the $400/month Claude Code plan tier. Step 1: Open Ultraplan from the Command Palette In Claude Code, open the command palette (Cmd/Ctrl + Shift + P) and type Ultraplan. Select “Claude Code: Start Ultraplan Session”. ...

Claude Code’s latest release (v2.1.9x) adds initialPrompt — a YAML frontmatter field that auto-submits a first turn when a subagent is spawned. This guide shows you exactly how to use it. What You’ll Accomplish By the end of this guide, you’ll have subagents that start executing immediately when invoked — no manual prompting required. Prerequisites Claude Code v2.1.9x or later (claude --version to check) An existing Claude Code project with at least one subagent definition Basic familiarity with YAML frontmatter in agent files Step 1: Update Claude Code First, make sure you’re on the latest version: ...

CVE-2026-33579 is a critical privilege escalation vulnerability in OpenClaw (CVSS 8.1–9.8) that allowed anyone with operator.pairing scope — the lowest permission level — to silently grant themselves full admin access. It was patched in v2026.3.28, but the exploit leaves no obvious trace. Security experts recommend that any OpenClaw instance running a pre-patch version should be treated as potentially compromised, even without visible evidence of breach. This checklist walks you through the full audit process. ...

CVE-2026-32211 is a CVSS 9.1 information disclosure vulnerability in Azure MCP Server. Missing authentication allows unauthenticated attackers with network access to read sensitive data — API keys, agent tokens, and data source credentials the MCP server manages. No credentials required to exploit. No prior access needed. This guide walks through the immediate mitigation steps while an official patch is pending, and the longer-term hardening practices that should apply to any MCP server deployment. ...
