You don’t need all of these. Pick the one that matches how you already work and add the rest later.
Claude Projects Simplest
No setup, no servers. Upload your files once and every conversation in that project starts knowing you.
- Open a Claude Project, or make a new one.
- Add your Context Kit files to the project knowledge.
- Add a project instruction — “You have my context files. Use them to inform your answers, but don’t narrate what you know unless I ask. Just know me.”
Update the files in the project whenever your work changes. Stale context is worse than none.
Custom Instructions or System Prompt Works Everywhere
The universal method. Paste your context into the system prompt or custom instructions of any tool — ChatGPT, Gemini, Claude, anything.
<user_context>
[paste identity.md]
[paste communication-style.md]
[paste any other files that fit the job]
</user_context>
You have context about me above. Use it to inform
your responses — my role, my projects, my voice, my
preferences. Don't reference it explicitly unless I
ask. Just know me.
For tools with a character cap (ChatGPT custom instructions), use just identity.md and communication-style.md — the highest value in the smallest space.
Claude Code For Building
Claude Code reads CLAUDE.md for context. Point it at your files and every session starts loaded.
## Personal Context
My Context Kit lives in ~/context-kit/. Read the
relevant files when you need to know who I am, how I
work, my current projects, or my preferences. Start
with identity.md if you only read one.
Or paste identity, communication-style, and preferences-and-constraints straight into CLAUDE.md if you’d rather not reference a folder.
MCP Resource Most Powerful
Expose your files as an MCP resource and any MCP-compatible tool pulls what it needs on its own — no copy-paste, and updates are automatic.
- Keep your files in one folder, e.g. ~/context-kit/.
- Point an MCP filesystem server at that folder.
- Connect any MCP client (Claude Desktop, Claude Code) and it can read your files on demand.
Start local with the filesystem server. If you want it across devices, ask Claude Code to help you stand up a small remote MCP server.
