Claude Cowork plugins updates: What's new in 2026

Anthropic's Claude Cowork just got a substantial update. On February 24, 2026, the company announced an expansion of its plugin ecosystem, new enterprise connectors, and platform features designed to make AI agents more accessible to knowledge workers across every department.

If you've been tracking the AI agent space, you know Claude Cowork made waves when it launched in research preview last month. The initial release triggered market reactions, including stock drops for legal software providers who suddenly faced competition from AI that could handle document review and analysis. This update shows Anthropic's push to move Cowork from an experimental tool to an enterprise-grade product.

Let's break down what's actually new and what it means for teams considering AI agents.

What are the Claude Cowork plugin updates?

The February 2026 updates represent a maturation of the Cowork platform. Anthropic is positioning these changes as the transition from research preview to a product ready for widespread enterprise deployment.

Key themes in this release:

• Department-specific plugins Pre-built agents tailored for HR, finance, engineering, design, and other functions
• Enterprise connectors Deeper integrations with the tools companies already use
• Admin controls Better governance and customization for IT teams
• Private marketplaces Organizations can build and distribute their own plugins internally

The updates are available to all Cowork users on paid plans (Pro, Max, Team, and Enterprise). If you're on a free plan, you'll need to upgrade to access the plugin ecosystem.

According to Kate Jensen, Head of Americas at Anthropic, the goal is to make Cowork "much more accessible and much more ready for anyone to be able to use." The company clearly sees an opportunity to capture enterprise market share, where it already derives roughly 80% of its business.

New plugins by department

Anthropic built ten new plugin categories, each designed with practitioners in the relevant field. The idea is that workflows, terminology, and outputs should reflect how work actually gets done, not generic AI responses.

HR

The HR plugin supports people operations across the employee lifecycle. It can draft offer letters, build onboarding plans, write performance reviews, and run compensation analyses. For HR teams drowning in administrative work, this could automate the repetitive documentation while keeping humans in the loop for decisions.

Design

Design teams get help with critique frameworks, UX copy drafting, accessibility audits, and user research planning. The plugin aims to accelerate design workflows without replacing the creative judgment that defines good design work.

Engineering

Engineering teams can use Cowork for standup summaries, incident response coordination, deploy checklists, and postmortem drafting. If you've ever stayed late writing up an incident report, this one's for you.

Operations

The operations plugin handles process documentation, vendor evaluations, change request tracking, and runbook creation. It's designed for the glue work that keeps companies running but rarely gets prioritized.

Financial analysis

Finance teams get support for baseline workflows: market and competitive research, financial modeling, and PowerPoint template creation with quality checking. The plugin targets the repetitive analysis work that consumes analyst time.

Investment banking

For deal teams, the investment banking plugin accelerates workflows like reviewing transaction documents, building comparable company analyses, and preparing pitch materials. Given the long hours in this industry, even modest time savings could add up quickly.

Equity research

Research analysts can use Cowork to parse earnings transcripts, update financial models with new guidance, and draft research notes. The plugin aims to streamline the information processing that underlies investment recommendations.

Private equity

PE firms get support for deal sourcing and diligence: reviewing large document sets, extracting standardized financial data, modeling scenarios, and scoring opportunities against investment criteria.

Wealth management

Advisors can analyze portfolios, identify drift and tax exposure, and generate rebalancing recommendations at scale. This could help advisors serve more clients without sacrificing personalization.

Brand voice (by Tribe AI)

This plugin analyzes existing documents, marketing materials, and conversations to distill brand voice into clear, enforceable guidelines. It's a meta-tool for maintaining consistency across all the other content your team produces.

New enterprise connectors

Plugins are only useful if they connect to the tools you already use. Anthropic announced several new connectors:

• Google Workspace Calendar, Drive, and Gmail integration
• DocuSign Document signing and workflow management
• Sales and marketing tools Apollo, Clay, Outreach, Similarweb
• Financial data MSCI, FactSet
• Legal LegalZoom, Harvey
• Content management WordPress

Partner companies have also built plugins for joint customers, including Slack by Salesforce, LSEG, S&P Global, Apollo, and Common Room.

The connector experience has been overhauled with an improved directory, streamlined admin controls, and easier management of which connectors are bundled into plugins.

Key platform improvements

Beyond new plugins and connectors, Anthropic introduced several platform-level features:

Private plugin marketplaces

Enterprises can now build private marketplaces to distribute custom plugins across their organizations. Admins control which plugins teams can access, including organization-specific marketplaces and private GitHub repositories as plugin sources (currently in private beta).

This addresses a real enterprise concern: how do you let teams benefit from AI agents while maintaining governance and consistency?

Plugin Create

Want something custom? Cowork now includes Plugin Create, a built-in plugin that walks you through building custom plugins from scratch. You can also start from Anthropic's templates and modify them. The company has published its plugin templates on GitHub for transparency and community contribution.

Slash commands with structured forms

Slash commands now launch with structured forms, so running a workflow like "generate report" or "create dashboard" feels like filling out a brief. Enter the details, and Claude takes it from there. It's a small UX improvement that could make AI agents feel more approachable to non-technical users.

Excel and PowerPoint integration

Perhaps the most technically interesting update: Claude can now handle multi-step tasks end-to-end across Excel and PowerPoint. It can use and pass context from one Office add-in to the other, making it possible to assign larger projects like running an analysis in Excel and turning it into a presentation in PowerPoint.

This is currently available in research preview for all paid plans on Mac and Windows. You'll need to download the add-ins for Claude in Excel and Claude in PowerPoint to try it.

OpenTelemetry support

For admins who need visibility, Anthropic added OpenTelemetry support for tracking usage, costs, and tool activity across teams. This matters for enterprises that need to justify AI investments or manage spend.

How to access the new plugins

Getting started with the new plugins is straightforward:

1. Open the Claude Desktop app and switch to the "Cowork" tab
2. Click the "Customize" menu in the left sidebar
3. Click "Browse plugins" to view all available options
4. Click "Install" on your selected plugin
5. Use slash commands (type /) to see available commands from your installed plugins

Plugins you add yourself are saved locally to your machine. If you're on a Team or Enterprise plan, your organization can also distribute managed plugins that maintain consistency across your team.

After installing, you can customize plugins to better fit your workflow. Click "Customize" on an installed plugin, and Claude will walk you through adjusting skills, commands, and connectors to match how you work.

Market impact and industry reaction

The announcement comes nearly three weeks after the initial Cowork plugins release triggered a plunge in stock prices for legal industry software providers. That disruption showed how AI technology is affecting knowledge workers and the shift underway as AI tools replace some entry-level work while augmenting high-level roles.

According to Lian Jye Su, an analyst at Omdia, "The decline in market valuation of the SaaS market shows that the market truly believes that AI technology is now ready to take over some of the more manual tasks in the professional service space."

Anthropic has secured notable partnerships, including PwC, which is partnering to bring enterprise-grade agents into the office of the CFO. Sanjay Subramanian, Anthropic Alliance Leader at PWC, framed it this way: "Three waves have reshaped professional work: productivity tools, cloud and search, and now agentic AI."

The company faces competition from big tech vendors like Salesforce and ServiceNow, as well as from OpenAI and Google. But Anthropic's enterprise focus, where it already generates roughly 80% of its business, gives it a clear target market.

Getting started with Claude Cowork plugins

Who should consider these updates? If you're a knowledge worker spending significant time on repetitive documentation, analysis, or coordination tasks, the new plugins are worth exploring. The department-specific focus means there's likely something relevant to your role.

Plan requirements are straightforward: you'll need a paid Cowork plan (Pro, Max, Team, or Enterprise). The core plugins and connectors are included; you don't pay extra per plugin.

For teams evaluating AI agents, this update makes Claude Cowork a more credible enterprise option. The private marketplace features, admin controls, and OpenTelemetry support address real enterprise concerns about governance and visibility.

If your focus is specifically on customer service automation rather than general knowledge work, tools like eesel AI offer purpose-built AI agents for support teams. We integrate directly with help desks like Zendesk and Freshdesk to handle frontline support tickets autonomously. The key difference: Claude Cowork targets general knowledge workers across all departments, while we focus specifically on customer service use cases.

For teams ready to experiment, the installation process takes minutes. Start with one plugin relevant to your daily work, test it on a few tasks, and expand from there. The risk is low, and the potential time savings are worth measuring.
