Claude Cowork vs. Claude Skills: what B2B teams need to know

What Claude Cowork is

Claude Cowork is Anthropic's agentic product for everyday knowledge work. The framing Anthropic uses is useful: it's built on the same architecture as Claude Code, but instead of writing software it handles the rest of your work. Formatted documents, synthesized research, organized files, multi-step tasks that would normally take you thirty minutes of context-switching. You describe what you need, Cowork plans the steps, executes them using your connected tools, and delivers a finished result.

Anthropic has said that more than 90% of what Cowork handles is not software development. It's the knowledge work every B2B team does every day: drafting, reviewing, compiling, formatting, summarizing. Cowork runs on desktop, web, and mobile across all paid plans. Tasks run in the background, so you're not watching Claude work; you hand it off and come back to finished output.

What Claude Skills are

In Claude's native product, a Skill is a reusable instruction set you save once and use everywhere. In chat, in Cowork, in Claude Code. The idea is straightforward: if you find yourself giving Claude the same instructions across different conversations, that's a Skill. You define it once, and every Cowork task or chat that touches that process follows the same instructions automatically.

That's the native definition. Claude Partners like TEG also build Skills in a more technical sense: custom automations built on Claude's API that handle structured inputs and outputs, connect to your CRM and other tools via MCP, and run operational workflows at volume. These are what most people mean when they say "we want to automate something with Claude." The underlying concept is the same (a defined process Claude follows consistently), but the implementation is more involved and the automation can do more.

How they work together

Skills and Cowork are not in competition. The relationship Anthropic describes is direct: Cowork is the agent that plans and acts; Skills are the instruction sets it follows for specific jobs. A Skill is not a replacement for Cowork, and Cowork is not a replacement for Skills. Cowork runs your Skills better than a conversation without them, because it has the full agentic context to execute them properly.

Think of it this way: Cowork is what does the work. A Skill is how to do a specific piece of it. If you have a weekly competitive analysis you want Claude to produce, Cowork handles the task. If you have a Skill that defines exactly how TEG wants competitive analysis structured, what sources to check, and what format the output takes, then every Cowork run of that task produces consistent output rather than a reasonable-but-variable interpretation.

The question that actually separates them

For most B2B teams, the decision isn't really Cowork versus Skills in isolation. It's a simpler question: does a human need to start this task, or should it run on its own?

Cowork is human-directed. You initiate a task, Cowork executes it. That's the right model for the majority of knowledge work, because most work benefits from a human deciding it's time to do it and reviewing what came back. Research, drafting, document review, synthesis. These are tasks where Cowork's design fits the actual workflow.

But some workflows shouldn't require a human to start them. A new lead comes into HubSpot and needs to be qualified. An inbound email arrives with a client request and should be routed and logged immediately. A weekly report should land in Slack every Monday morning whether or not anyone remembered to ask for it. For those workflows, you don't want Cowork, because Cowork still requires a human to initiate each run. You want a built automation that fires on the event and runs to completion without waiting for anyone.

Scheduled Tasks: the middle ground

Anthropic added Scheduled Tasks to Cowork, which covers a meaningful slice of what used to require a fully custom automation. You define a Cowork task once and set a cadence: hourly, daily, weekly. Cowork runs it on schedule, with full access to your connected tools and Skills, and delivers the output whether or not your device is online. A daily briefing, a weekly pipeline summary, a recurring research pull.

Scheduled Tasks are worth knowing about because they extend Cowork's value significantly for recurring knowledge work. You don't need a custom build for a daily market brief or a weekly competitor summary. Set the Cowork task, add the right Skills, schedule it, and it runs.

What Scheduled Tasks can't do is respond to events in other systems. They run on time, not on triggers. If you want Claude to act when something happens in HubSpot, not on a calendar, you need an event-driven automation, not a scheduled one.

When to use Cowork (with or without custom Skills)

Cowork is the right tool when you're driving the work. Complex, variable tasks where the shape of the output depends on what you're working with that day. Multi-step research or synthesis that benefits from your judgment at the end. Tasks that run occasionally and don't have a fixed structure. Anything where you want to supervise the output before it goes anywhere.

If you use the same workflows repeatedly, add native Skills to standardize how Claude handles them inside Cowork. If those workflows connect to external data (pulling from a report, referencing a live data source), add MCPs that give Cowork access. That combination, Cowork plus Skills plus relevant MCP connections, handles most B2B knowledge work without custom development.

When to build Skills that run without Cowork

Build a custom Skill (or a full automation) when the workflow needs to run without a human initiating it. When it needs to trigger on an event: a new record, an inbound message, a form submission, a status change in your CRM. When it needs to write back to your systems as part of its output, not just produce a document for a human to copy from. When it needs to run at a volume where human initiation is a bottleneck.

These are the automations TEG builds. A lead comes into HubSpot, the automation fires, Claude evaluates it against your ICP, writes a qualification summary and recommended next action back to the CRM record, and routes it to the right rep, all before anyone on your team has looked at it. No one started a Cowork task. The automation is sitting in your infrastructure, waiting for the trigger, and running every time.

What TEG builds, and when it makes sense

TEG implements both. We help teams configure Cowork and set up the Skills and MCP connections that make it more consistent and more capable. We also build the event-driven automations that run without Cowork, triggered by activity in your actual systems.

The honest answer about which one your team needs is: both, for different things. Cowork handles the knowledge work your team directs. Custom Skills handle the operational processes that should run without anyone directing them. Teams that get the most value from Claude have figured out which workflows belong in which category.

TEG offers a free training session to help B2B teams work through exactly that: where Cowork fits, where you need something built, and what implementation actually looks like in your stack.
