👋 Welcome to the September Edition!
This week, we’re looking at how AI agents are moving deeper into developer workflows, what’s happening across the Node.js community, and how NodeSource is bringing runtime diagnostics and security context directly into developer and AI-assisted environments.
Here’s what’s inside:
🤖 AI-Powered Dependency Auditing: See how the N|Solid Plugin + Codex can turn Node.js dependency vulnerabilities into actionable upgrade recommendations using NCM vulnerability intelligence.
🧩 N|Solid DevTools: Bring live Node.js telemetry, CPU profiles, heap snapshots, performance insights, and package security directly into VS Code, Cursor, Windsurf, and compatible editors.
🌎 Community & Events: Catch up on Node.js Interactive 2026, explore the NodeConf EU program, and discover the upcoming virtual JS Days 2026 conference.
🤖 AI Corner: Recommended reads on autonomous coding agents, collaborative agent workflows, and how tools like Cursor, Slack, Codex, and GitLab are pushing AI deeper into the software development lifecycle.
🚀 Node.js Upgrade Program: Learn how organizations running End-of-Life Node.js versions can get free expert guidance to plan and execute their next upgrade.
Happy reading! 🚀

🤖 nsolid-plugin v1.0.3 is now available
A new version of the N|Solid Plugin is out, making it easier to work across organizations and improving the experience for AI coding agents connected to N|Solid.
This release includes:
- 🏢 Organization switching with the new
switch-orgcommand andns-switch-orgskill - 🔗 Improved MCP URL handling
- 🧪 Test reliability fixes
The N|Solid Plugin gives AI coding agents access to real Node.js runtime context — including telemetry, CPU profiles, heap snapshots, package security insights, and application benchmarks — so they can investigate issues using production evidence, not just source code.
👉 Install nsolid-plugin v1.0.3

🟢 N|Solid is getting ready for Node.js 26 LTS
N|Solid is already running on top of Node.js 26.7.0, with the full test suite passing.
That means the groundwork is in place for N|Solid to support Node.js 26 as it moves toward LTS — helping teams adopt the next LTS line while keeping the production diagnostics, security intelligence, and runtime visibility they rely on.

🤖 AI Corner
AI coding agents are becoming collaborative workflows
GitHub’s latest Copilot updates show where AI-assisted development is heading: beyond a single developer chatting with an agent.
Recent additions include shared agent sessions from Slack and Microsoft Teams, the ability to continue Copilot or Claude agent sessions inside VS Code, organization-wide custom agents, and even an experimental /rubber-duck command that asks a complementary model for a second opinion.
The interesting shift: agents are becoming part of the development workflow itself — across IDEs, repositories, reviews, and team conversations.
👉 Explore GitHub Copilot’s latest updates
💡 AI Tip of the Week
Ask another agent to challenge the first one
Don’t only ask your coding agent to generate a solution.
Before accepting a meaningful change, try asking a second model or agent to review it specifically for:
- incorrect assumptions
- edge cases
- security issues
- unnecessary complexity
- regressions
A useful prompt can be as simple as:
“Review this solution as a skeptical senior engineer. Don’t rewrite it yet — identify assumptions, risks, and edge cases the original implementation may have missed.”
This “second opinion” pattern is becoming increasingly common in agentic development workflows — and GitHub is even experimenting with it directly through Copilot’s /rubber-duck command.

Automating repetitive work at OpenAI with Codex
A practical look at how an OpenAI engineer uses Codex to handle recurring engineering work while keeping humans involved in planning, approvals, and consequential decisions.
Instead of creating one-off automation for every repeated task, the workflow captures context, commands, results, decisions, and lessons learned so future agent runs can build on previous work.
It’s a particularly interesting example of an important agentic pattern: don’t just automate the task — preserve the context generated while solving it.
