Cursor Remembers What You Decided

Your .cursorrules stays in sync with every other tool automatically.

The Problem

Cursor's AI reads your codebase fresh each session. .cursorrules provides static instructions but can't capture dynamic knowledge — what was tried, what failed, what the team decided last week. And it doesn't know what you told Claude Code yesterday.

Static rules vs. live verified memory.

• • • .cursorrules (static)

# .cursorrules (static file)

Use TypeScript strict mode

Prefer functional components

# Last updated: 3 weeks ago

# No verification. No timestamps.

• • • VerifiedState (live)

✦ VerifiedState · 34 assertions · live

TypeScript strict mode ✓ rct_a1b2

Functional components ✓ rct_c3d4

Switched to Tailwind v4 ✓ rct_e5f6

(2 hours ago, replaces custom CSS)

Static file vs. living memory. No contest.

The Fix

Run vsync or connect via MCP:

bash
npx @verifiedstate/sync start
# That's it. Your .cursorrules syncs with CLAUDE.md automatically.

# Or connect via MCP:
# Cursor Settings → MCP → Add Server
# URL: https://mcp.verifiedstate.ai/mcp

Without VerifiedState vs. With VerifiedState

Feature	Without	With VerifiedState
.cursorrules	Static text file, local-only	Auto-synced with CLAUDE.md and every tool
Session context	Gone after close	Persisted + queryable
Team decisions	In Slack threads	Verified assertions with timestamps
What was tried	"I think we tried that"	Receipt proving it

FAQ

Does this replace .cursorrules?

It complements it. .cursorrules is static. VerifiedState syncs it with CLAUDE.md and adds dynamic memory that grows as you work.

How do I set it up?

Run npx @verifiedstate/sync start in your project. Or add the MCP server in Cursor settings. Takes 30 seconds.

Will changes in CLAUDE.md appear in .cursorrules?

Yes. vsync watches both files and syncs matching sections bidirectionally. Hash-based loop prevention ensures no infinite cycles.
