Feature suggestion: reusable context / pinned rules based on real-world usage

Dear DeepSeek team,

I want to share a workflow pattern that has proven very effective for me and might inspire a useful feature.

Context: I use DeepSeek Chat intensively for software development. My project has a fixed tech stack (C#, Blazor, MudBlazor, EF Core, SharePoint integration) and a specific set of coding conventions and interaction rules (e.g., "don't generate code until I explicitly ask", "no temporary workarounds", "follow MudBlazor docs strictly").

Challenge: Since the model doesn't retain memory between chats, every new session requires me to re-explain the entire context — which is time-consuming and error-prone.

Current workaround: I created a dedicated "master chat" where I pasted all the project rules, conventions, and technical details. Now, whenever I start a new chat, I simply provide a link to that master chat and the model immediately adopts the correct behaviour. It's essentially a poor man's "pinned messages" feature — and it works remarkably well.

Feature suggestion: A native "pinned instructions" or "project profile" feature would be incredibly valuable for long-term users. Something as simple as a text field that is automatically prepended to every new chat could dramatically improve the experience for professional use cases.

I'd be happy to provide more details or examples if helpful.

Thank you for your great work!
