The Problem

Claude Code is powerful but stateless between sessions. It re-reads your codebase every time. It doesn't remember your preferences, your architecture decisions, or the bugs it already fixed. CLAUDE.md helps, but it's manual, unversioned, and doesn't sync to your other tools.

Context survives session resets.

• • • Session 1
> Use Tailwind, not custom CSS
✓ Stored · rct_f92e · 0.98
• • • Session 2 (next day)
> How should I style this component?
✦ Loading session context...
Use Tailwind — decided yesterday.
Receipt: rct_f92e · still valid

Same project. Different day. Memory intact.

Verify + Receipt

The Fix

Run vsync or connect via MCP:

bash
npx @verifiedstate/sync start # That's it. Your CLAUDE.md syncs with .cursorrules automatically. # Or connect via MCP: claude mcp add verifiedstate --transport http https://mcp.verifiedstate.ai/mcp # Add to CLAUDE.md: # After every task, call session_save to persist context.

What You Get Back

✓ VERIFIED
receipt.json
{ "receipt_id": "rct_7f3a...", "assertion": "User prefers dark mode", "status": "verified", "confidence": 0.94, "signature": "ed25519:a8c3f1...", "verified_at": "2026-04-06T14:32:01Z", "chain_position": 42 }

Without VerifiedState vs. With VerifiedState

CLAUDE.md Manual, unversioned, local-only Auto-synced to .cursorrules and every MCP tool

FAQ

Does this replace CLAUDE.md?

It complements it. CLAUDE.md is static instructions. VerifiedState syncs those instructions to other tools and adds dynamic verified memory on top.

How fast is session_load?

Under 100ms for full session context restore.

Which Claude Code version?

Any version that supports MCP servers.

Do I need to configure anything after npx?

No. vsync detects CLAUDE.md and .cursorrules in your project automatically. It just works.
