Building Your Claude Context Files

Claude works best when it already knows who you are, what your business does, and how you like to write. Instead of re-explaining yourself every chat, build three small reusable context files — and you don't write them yourself. You give Claude a prompt, answer its questions, and it writes each file for you.

What are the three context files?

Plain-English definition: a ".md" (Markdown) file is a simple text file with headings that Claude reads easily.

Once built, they're used two ways:

• Uploaded to a Claude Project, so every chat in that Project has them automatically.
• Saved to memory with one extra prompt, so the key facts follow you into regular chats too.

How do I create aboutme.md?

I want to create an "aboutme.md" file that you can use as background context in every conversation we have. Ask me questions one at a time to build it — cover my name, my role/title, what I'm responsible for day to day, my working style (e.g. how much detail I want, how direct to be with me), my current priorities, and anything I frequently need help with. Once you have my answers, write the final file in clean markdown with headers.

Claude will interview you — just answer naturally. When it's done, it hands you a finished file.

How do I create mybusiness.md?

Now let's build "mybusiness.md" — the standing facts about my business that you should always know. Ask me about: what we do and who we serve, our products/services, our pricing model, our team size and key people, our busiest season or cycle, our biggest current goal, and anything that's commonly misunderstood about the business that you should never get wrong. Then write the final file in clean markdown.

How do I create myvoice.md?

This works best with 2–3 real examples of things you've actually sent — an email, a social post, a message to a client.

I want you to build "myvoice.md" so you can write in my voice going forward. I'm going to paste 2-3 examples of things I've actually written (an email, a social post, a message to a client — whatever's easiest). Analyze them for: sentence length and rhythm, vocabulary level, how formal or casual I am, how I open and close messages, words or phrases I use often, and things I never do (e.g. "I never use exclamation points" or "I never start with 'I hope this finds you well'"). Then write the final file as a style guide I can reuse.

Here are my writing samples:
[paste 2-3 real examples]

No samples handy? Just tell Claude a sentence or two about your style — for example: "I'm casual but direct, I use short sentences, I never open with 'I hope this email finds you well.'" It'll be less precise but still useful.

How do I save the key facts to memory?

Once all three files are built, paste this:

Please remember the key facts from the aboutme.md, mybusiness.md, and myvoice.md we just built, so you have this context in future chats too.

Where should these files live?

1. Today: Claude generates each file in the chat — copy the finished text or download it.
2. Next: upload all three into your Claude Project's knowledge panel so any chat in that Project uses them automatically.
3. Ongoing: if your role, business, or voice changes, ask Claude to update the file and re-upload the new version.
