AI tools write great code. They just don't know your architecture.

We love Cursor. We love Claude. We love Copilot.
But six months ago we noticed something quietly breaking our codebase.

Not bugs. Not bad code. Drift.
Our AI tools kept generating perfectly functional code that slowly violated decisions we'd already made as a team. The repository pattern we'd agreed on. The state management library we'd picked after two weeks of debate. The validation approach our senior engineer insisted on.
None of it was anywhere AI could actually read.

It lived in:

• A Slack thread from 8 months ago
• An ARCHITECTURE.md nobody had touched in a year
• Three .cursorrules files that contradicted each other
• One senior engineer's memory So AI guessed. And every wrong guess added one more brick of drift.

The fix we built:
Hopsule is a memory layer that sits between your team's decisions and your AI tools.
You record a decision once. Hopsule structures it, versions it, and injects it into every AI session automatically via MCP.

Example:
Your team accepts: "Database access must go through the repository layer."
Every Cursor, Claude, or Copilot session that follows knows it, without you typing it again.

Mental model:
Humans decide. Hopsule stores. AI follows.

What's included:

• MCP server (Cursor, Claude, Copilot)
• IDE extension for inline enforcement
• CLI Tool (npm i -g hopsule)
• Decision lifecycle (Draft → Accepted → Deprecated)
• GitHub Sync
• Decision Graph

Advisory-only. We never block your code, just surface conflicts where they happen.

Honest question for devs:
How are you keeping your AI tools aligned with your architecture today? .cursorrules? ARCHITECTURE.md? Nothing?
Would love to hear what's working and what isn't.
