You already know how to use Claude. This guide covers the three layers that turn it into a genuine productivity multiplier — Skills, Plugins, and Cowork. The difference between a tool you use and a capability that compounds.
Right now, Claude is like a brilliant contractor who starts fresh every time they walk through your door — no memory of how you like things done. Skills give them your standing brief — your preferences, your context, your standards — so they just know. Plugins make them a specialist — already wired into your tools, ready to operate in your domain. Cowork gives them a desk — they're working on your machine, in your files, getting things done while you're in a meeting.
| Layer | What it does | Effort to set up | Best for |
|---|---|---|---|
| Skills | Saved instructions Claude applies automatically in every session | Low — write once | Your tone, style, recurring task formats |
| Plugins | Pre-built bundles of skills + tool connectors + sub-agents | Zero — just install | Role-specific workflows & app integrations |
| Cowork | Autonomous desktop agent that reads, edits, and creates your files | Low — describe the outcome | Multi-step work you want off your plate |
Persistent instructions you write once. Claude follows them in every future conversation.
Pre-built specialist bundles. Install and Claude becomes an expert in your domain instantly.
Claude on your desktop. Give it a goal, walk away. Come back to finished work.
Think of Skills like the standing brief you'd give a great EA before handing them work. You don't re-explain your communication style, your preferred formats, or your industry context every time — they know it already. That's what a well-written Skill does for Claude. Every chat, every Cowork task, every Plugin session: Claude already knows how you work.
Persistent Memory
Skills are saved to your Claude account and applied automatically in every conversation — no need to paste instructions repeatedly.
Behaviour Instructions
Tell Claude your preferred tone, output format, what to avoid, role context — anything you'd normally type at the start of every chat.
Write Once, Use Always
You create a skill once. It applies in every subsequent chat, Cowork task, and plugin session automatically.
User Skills (Your Preferences)
Your personal instructions — tone, communication style, context about your role. Example: "I'm a business consultant. Always reply concisely. Use bullet points only when I ask. Avoid jargon." These apply across all your Claude conversations.
Task Skills (Workflow Templates)
Instructions for a specific recurring task. Example: "When I paste a client email, draft a professional reply in under 150 words, flag any risks, and suggest a follow-up action." You invoke these on demand.
Custom Instructions (Advanced)
Deeper configuration — reference documents, multi-step process logic, conditional behaviour. These are often packaged inside Plugins (Module 2).
Go to Settings → Custom Instructions (or User Preferences)
In Claude.ai: click your profile icon → Settings. In Claude Desktop: Settings in the top menu. You'll see a text box — that's where your Skill lives.
Think about what you type at the start of every chat
Whatever context you find yourself repeating — your role, your industry, your output preferences — that belongs in a Skill. Start there. You can always add more later.
Write it in plain language, like a brief to a colleague
No special syntax needed. Just explain who you are, what you're typically doing, and how you like Claude to respond. Under 400 words to start — quality over quantity.
Open a fresh chat and notice the difference
Claude will apply your Skill from the first message. If something feels off, tweak the Skill — it usually only takes one or two iterations to get it right.
Plugins are like app stores for Claude's brain. Instead of configuring everything yourself, someone has already done the work — bundled the right skills, the right connectors, the right sub-agents — and packaged it into a single install. You tap install, and Claude shows up as an expert from day one.
Skills
Pre-written instructions that define how Claude should behave in your context — your industry language, workflow steps, output formats.
Connectors
Connections to external tools — Slack, Google Drive, CRMs, email, project management platforms. The Plugin wires them up automatically.
Sub-agents
Specialised mini-Claude instances within the Plugin that handle specific tasks — research, formatting, data extraction — without you directing them step by step.
| Feature | Skills | Plugins |
|---|---|---|
| Who creates it | You | Developers / community / Anthropic |
| Setup effort | Medium — you write the instructions | Zero — just install |
| Contains | Instructions only | Instructions + tools + connectors + agents |
| Customisation | Fully custom to you | Install as-is, some allow tweaks |
| Best for | Your personal workflow | Industry tools & role-specific work |
Open Settings → Plugins (in Claude Desktop or Claude.ai)
The plugin browser is built into Claude's settings. You can browse by category, role, or tool integration.
Browse by category or search by tool name
Search for tools you already use — Slack, Notion, HubSpot, Google Workspace, etc. If there's a Plugin, Claude can connect to it.
Click Install — grant any permissions it needs
Some Plugins need to connect to external accounts. You'll be prompted to authorise access — Claude only gets what you approve.
Activate it in Cowork or Chat
Once installed, switch it on in a Cowork session or a Chat window. Claude will automatically operate as a specialist from that point.
Marketing & Growth
Content creation, campaign management, analytics summaries, SEO workflows.
Data & Research
Web scraping, data synthesis, report generation, competitive analysis.
Communication
Email management, Slack digests, meeting prep, client communication.
Workflow Automation
n8n, Zapier-style connectors, scheduling, cross-app task management.
Imagine hiring a highly capable assistant and giving them their own desk in your office — access to your filing system, your applications, your calendar. You say "put together the Q2 report from these folders and email it to the team by Friday" and walk away. That's Cowork. Claude isn't answering a question. It's doing the work.
| Situation | Chat does this | Cowork does this |
|---|---|---|
| Organise my Downloads folder | Tells you how to organise it | Opens the folder, sorts it, renames files, done |
| Compile a report from 6 documents | Tells you what to include | Reads all 6, synthesises, writes the draft |
| Weekly metrics digest | Gives you a template to fill in | Runs every Friday, pulls data, sends it automatically |
| Export deck as PDF + attach to invite | Explains the steps | Opens PowerPoint, exports, attaches to calendar invite |
Claude Desktop App
Cowork requires the desktop app — available for macOS and Windows. Not available on the web version. Download at claude.ai/download.
Paid Plan Required
Available on Pro ($20/mo), Max ($100/mo), Team, and Enterprise. Not available on the free tier. Pro is fine to start.
Folder Permissions
You choose exactly which folders Claude can access. It cannot touch anything outside what you explicitly grant. You control this in Settings → Cowork.
Open Claude Desktop and click the "Cowork" tab
You'll see it alongside Chat and Code at the top. Click it to switch into Tasks mode.
Grant folder access (first time only)
Go to Settings → Cowork → Edit Folders. Add the folders you want Claude to work with. Start conservative — one or two project folders.
Describe the outcome, not the steps
Don't say "open file X, then do Y". Say "Compile a summary of all the documents in my /Reports folder and save it as a new file called Summary-March.docx." Claude figures out the steps.
Review the plan before Claude acts
Cowork shows you what it's going to do before it does it. Review, redirect if needed, then approve. You're always in control.
Walk away (or watch in real time)
Claude shows its progress live. You can leave and come back, or monitor step by step. Either works. The desktop app must stay open.
Scheduled Tasks
Type /schedule in any Cowork task. Claude will run it automatically on your chosen cadence — daily, weekly, or on-demand. Your computer must be awake.
Projects
Group related tasks into persistent workspaces with their own files, context, and memory. Great for ongoing client work or recurring projects.
Dispatch (Mobile)
Assign tasks from your phone. Claude completes them on your desktop. You don't have to be at your computer — just send the instruction and check back later.
Computer Use (Mac)
Latest feature: Claude can directly control your Mac — open apps, click buttons, navigate browsers — when no direct connector exists. Currently macOS only, research preview.
Your Skill is the standing brief — who you are, how you work. Your Plugin is the specialist toolset for your role. Cowork is where that specialist actually executes, using your files, your tools, your systems. Together: you describe the outcome once, and a trained-up expert handles the rest.
Skill
"When summarising data, always use the format: headline metric, key insight, recommended action. Keep it under 250 words."
Plugin
Install a data connector Plugin (e.g. Google Analytics, HubSpot, or your CRM) so Cowork can pull live metrics automatically.
Cowork
Schedule: "Every Friday at 4pm, pull this week's metrics, apply my report format, and save it as Weekly-Report-[date].docx in /Reports."
Skill
"I'm a consultant. When drafting client emails: professional but warm. Flag anything that needs legal review. Never commit to deadlines without me confirming."
Plugin
Install a Gmail or Outlook connector Plugin for direct email access.
Cowork
"Every morning, scan emails from the last 12 hours. Flag anything urgent, draft replies for anything straightforward, and summarise the rest."
Skill
"When summarising documents, lead with the most important takeaway, then context, then recommended action."
Cowork (no Plugin needed)
"Read all PDFs in my /Contracts folder. Create a one-page summary of each. Save them with the naming format: Summary-[original filename].docx"
Day 1–2: Write your User Skill
Open Settings → Custom Instructions. Write 3–5 sentences about your role and communication preferences. Test it in a chat.
Day 3: Download Claude Desktop + activate Cowork
Download the desktop app. Grant access to one non-sensitive folder. Try one simple file organisation task to see how it works.
Day 4–5: Browse and install one Plugin
Go to Settings → Plugins → Browse. Find something for a tool you already use. Install it and run a task through Cowork using it.
Day 6–7: Set up your first scheduled task
Pick one repeating task you do every week. Type /schedule in Cowork. Set the cadence. Walk away and let it run.
