GUIDES
The Claude Control Hierarchy Most People Ignore 📚
There are 3 levels that control how Claude behaves in Cowork. Most people only use one. Free guide by Somya Nayak.
Why Cowork feels inconsistent
Here's something most people don't realize: Cowork has no memory between standalone sessions. Every time you start a new task, it starts from scratch. That's why Claude is great sometimes and completely off other times. It's not random. It's because you're not giving it the right context at the right level.
There are three levels that control how Claude behaves. Most people only set up one (if that). Once you set up all three, Claude stops guessing and starts working the way you need it to. Every time.
Level 1
Global Instructions
Global Instructions are the baseline rules Claude follows in every single session, every task, every project. You set them once and they apply everywhere. This is where you tell Claude who you are and how you always want things done.
How to set it up
Go to Settings → Cowork → Global Instructions → Edit. Write your instructions and save. These load automatically before every task.
What to put here vs. somewhere else
Global Instructions should only contain things that are true for ALL your work. Your identity, your communication preferences, your non-negotiables. Anything that's project-specific goes in Level 2.
Level 2
Context Files (Your Folder)
This is where most people drop off, and it's the most important one. When you give Cowork access to a folder, it reads the files in that folder at the start of every session. So you create markdown files that tell Claude everything it needs to know about that specific project.
Different folders = different context = different behavior. Your client work folder has different rules than your internal reporting folder. A marketing project needs different context than a hiring workflow. That's the whole point.
Why this matters so much
Since Cowork has no memory between sessions, these files ARE your memory. Think of them like an onboarding document for a new employee, except this employee reads the document every single morning before starting work and never forgets a word. You write it once, and it compounds over time as you tweak it.
Create a folder for your project and add these three files:
Recommended folder structure
Keep your project folder organized so Claude knows where to find and save things:
/your-project/
about-me.md
voice-and-style.md
working-rules.md
/templates/ — examples of output you like (past reports, email samples)
/references/ — brand guidelines, project briefs, read-only context
/drafts/ — work in progress
/outputs/ — finished deliverables
Folder instructions override global
If your Global Instructions say "use a casual tone" but your folder's voice-and-style.md says "formal and polished," Claude follows the folder context for that project. Global sets the default. Folder context overrides it when there's a conflict. That's how you get different behavior for different projects without changing your settings every time.
Level 3
Skills
Skills are the specific actions Claude takes, triggered by /slash-commands. You type /call-prep or /draft-brief and Claude runs that exact workflow every single time. No re-explaining. No hoping it remembers. One command, consistent output.
In Cowork, Skills are way more powerful than in regular Chat. They're operational. They govern every file Claude creates, and they combine automatically when a task crosses domains. Ask for a presentation with data analysis, and your presentation skill and your data skill both activate without you doing anything.
How to create a Skill
The easiest way: use Cowork's built-in Skill Creator. It interviews you about what you need, then generates a properly structured skill file. You can also tell Claude directly: "Save this as a Skill called /[name]" and describe what you want. Or build them manually as markdown files in your skills folder.
Pro tip: chunk your skills by domain
Don't build one massive "writing" Skill. Build separate ones: /client-email for client communication, /internal-update for team updates, /blog-draft for content. Each one has its own rules, tone, and format. Claude loads only what's relevant per task instead of trying to apply one set of rules to everything.
How the three levels work together
Global Instructions
Control everything. Your identity, your preferences, your non-negotiables. Always on, every session.
Context Files
Define the project. Who it's for, what the rules are, what good output looks like. Changes per folder.
Skills
Tell Claude the work to do. Repeatable actions you trigger with one command. Consistent every time.
When all three are set up, Claude knows who you are (Global), understands the project (Context Files), and knows exactly what to do when you ask (Skills). That's when Cowork stops feeling like a chatbot and starts feeling like someone who actually works with you.
Things most people miss
Always request a change log
Add this to your working-rules.md: "When you're done, produce a change log of every file you created or modified." This way you can review every decision Claude made instead of digging through folders wondering what changed.
Put examples in your /templates/ folder
Claude pattern-matches against examples better than it follows abstract rules. If you want your reports to look a certain way, don't just describe the format. Drop an actual example in /templates/ and tell Claude to reference it. The output quality jumps immediately.
Update your context files as you go
These files compound over time. Every time Claude gets something wrong, add a rule to prevent it. Every time your role evolves, update about-me.md. The people who get the most out of Cowork are the ones who treat these files like living documents, not a one-time setup.
