How-Tos & Practical Guides

Anthropic’s Mythos-class models come with a non-negotiable privacy tradeoff: mandatory 30-day data retention for all conversations. Zero Data Retention (ZDR) is off the table — not restricted to specific use cases, not configurable, simply unavailable for Fable 5 and Mythos 5 on any platform. If you run agentic workflows with sensitive data and you’ve been operating under a ZDR arrangement, upgrading to Fable 5 or Mythos 5 isn’t just a model swap. It’s a compliance review. ...

OpenClaw v2026.6.5 has landed, and it’s one of the more consequential point releases in recent memory. Across 216 merged pull requests, the team has shipped two headline features — built-in parallel web search with no API key required for basic use, and a new security.installPolicy control for governing skill and plugin installations — while quietly hardening everything from Discord delivery to Anthropic extended-thinking resilience. Here’s what you need to know, and how to actually use it. ...

One day after v2026.6.5 shipped, OpenClaw pushed v2026.6.6-beta.1 onto the pre-release track — and it’s almost entirely security fixes. Seventeen distinct boundary tightenings across exec approvals, transcript redaction, sandbox binds, MCP stdio, Codex HTTP access, and more. If you run OpenClaw in anything resembling a production environment, this beta is worth a close read before it merges to stable. The single most important change: exec approvals now fail closed on timeout. Let’s unpack what that means and why the rest of this release matters. ...

Clock Is Ticking: Claude Fable 5 Free Access Ends June 22 — Here’s What to Audit Now Claude Fable 5 launched on June 9, 2026. If you’re using it on a Claude Pro, Max, Team, or Enterprise plan, you’re currently getting access at no extra cost. That changes in 12 days. On June 22, 2026, Claude Fable 5 shifts to usage-based billing at 2× the credit rate of Claude Opus. The API pricing: $10/million input tokens, $50/million output tokens. If your workflows — especially agentic ones — are currently running on Fable 5 without you fully tracking that, you could be in for a surprise bill or abrupt capability reduction after the deadline. ...

MCP’s 2026 Roadmap: Progressive Discovery, Programmatic Tool Calling, and What’s Coming Next The Model Context Protocol has had a breakout year — 97 million SDK downloads, adoption by OpenAI, Google, Microsoft, AWS, and the Linux Foundation, and a growing ecosystem of MCP servers covering everything from database access to browser automation. At the June 2026 MCP Dev Summit, Anthropic’s David Soria Parra (the co-creator and lead of MCP) laid out where the protocol is heading next. ...

OpenClaw v2026.6.5 — Free Parallel Search, MCP Hardening, and 216 Merged PRs The June stable train for OpenClaw just landed, and v2026.6.5 is one of the more substantive releases in recent memory. With 216 pull requests merged since v2026.6.1, this update touches nearly every layer of the platform — from first-run experience to MCP reliability to channel output safety. Here’s what shipped and why it matters. Parallel Search Is Now Free Out of the Box The headline feature is Parallel Search Free — zero-setup web search that works on a fresh OpenClaw install with no API keys required. When no other search provider is configured, the parallel-free Search MCP provider activates automatically. Rather than running web searches one at a time, agents can now fan out multiple queries simultaneously, which meaningfully accelerates any workflow involving research, competitive analysis, or content synthesis. ...

AG2 — the framework formerly known as AutoGen — just released version 0.13.3, and it represents a significant architectural leap for teams building distributed multi-agent systems. The three headline features — Cross-Process Network, background_agent_tool, and LocalSandbox — collectively unlock patterns that were either impossible or very awkward to implement in previous AG2 versions. Background: Where v0.13.x Fits AG2 has been in a major architectural transition since v0.13.0, building toward a v1.0 milestone. The 0.13.x series introduces the new “Network” abstraction for agent communication. Prior to v0.13.0, agents in AG2 communicated in-process — workable for single-machine setups, but limiting for production-scale distributed workflows. ...

AI coding agents are writing code faster than ever — but at enterprise scale, the question is no longer just “did the agent write correct code?” but “can I trust what the agent built, packaged, and shipped?” JFrog and Anthropic answered that question today with the launch of an official JFrog plugin for Claude Code, bringing the supply chain governance capabilities that enterprise security teams need directly into the AI coding workflow. ...

OpenClaw just shipped its most consequential stability and security release in months. Version 2026.6.5 — built under the new YYYY.M.PATCH versioning scheme — delivers three headline capabilities that practitioners have been waiting for: zero-config parallel web search, fine-grained plugin installation governance, and dramatically hardened MCP recovery behavior. If you’re running OpenClaw in any production or multi-user capacity, this release deserves your immediate attention. New Versioning Scheme Before diving into features, note the format change: OpenClaw has moved from a traditional v0.x.y style to calendar-based YYYY.M.PATCH numbering starting with this June 2026 train. The practical effect is that you’ll now see v2026.6.5 instead of something like v0.22.5. This makes it easier to track roughly when a release was made and how current your installation is. ...

The clock is ticking. Anthropic announced back on April 14, 2026 that claude-sonnet-4-20250514 and claude-opus-4-20250514 would be retired from the API — and that retirement happens on June 15, 2026 at 9AM PT. There is no grace period. When the clock hits, API calls using these model IDs will error immediately. If you haven’t migrated yet, you have five days. Here’s your checklist. What’s Being Retired Model ID (retiring) Retirement date Recommended replacement claude-sonnet-4-20250514 June 15, 2026 9AM PT claude-sonnet-4-6 claude-opus-4-20250514 June 15, 2026 9AM PT claude-opus-4-6, claude-opus-4-7, or claude-opus-4-8 Note: GitHub Copilot already deprecated Sonnet 4 in May 2026. If you’re on Copilot, that may already be resolved, but double-check any API integrations you maintain separately. ...
