+---
+
+No-Going-Zone (NGZ) is an onchain habit accountability tracker on Base. Users declare a habit, check in daily to build a streak, earn soulbound milestone NFTs at 7, 30, 90, 180, and 365 days, and face permanent onchain consequences — a Wall of Shame NFT — when they relapse. All data lives onchain with no backend or database.
+
+The NGZ action provider lets any AgentKit-powered agent read leaderboard data, look up user stats, and send transactions on behalf of a user.
+
+## Install
+
+Add the NGZ action provider to your AgentKit instance:
+
+```bash Terminal
+npm install @coinbase/agentkit
+```
+
+```typescript TypeScript
+import { AgentKit } from "@coinbase/agentkit";
+import { ngzActionProvider } from "@coinbase/agentkit";
+
+const agentKit = await AgentKit.from({
+  walletProvider,
+  actionProviders: [ngzActionProvider()],
+});
+```
+
+## What the skill covers
+
+| Action | Wallet required | Description |
+|--------|-----------------|-------------|
+| `get_ngz_leaderboard` | No | Fetch top streak holders ranked by current streak |
+| `get_ngz_user` | No | Look up a user's full stats by wallet address |
+| `get_ngz_wall_of_shame` | No | Fetch recent relapse events from the Wall of Shame |
+| `check_in_ngz` | Yes | Record today's check-in to maintain your onchain streak |
+| `tip_ngz_user` | Yes | Send ETH respect directly to another user's wallet |
+
+## Example prompts
+
+```text
+Show me the top 10 users on the NGZ leaderboard
+
+Look up the NGZ profile for 0x1234...abcd
+
+Show me the latest relapses on the NGZ Wall of Shame
+
+Check me in on NGZ to keep my streak going
+
+Send 0.001 ETH tip to 0x1234...abcd on NGZ with the message "Keep going!"
+```
+
+## Networks
+
+Supported on `base-mainnet` and `base-sepolia`.
+
+<Note>
+  The NGZ contract is currently deployed on Base Sepolia testnet at `0x4D1b5da45a5D278900aedfc6c96F0EE0D4e28bF6`. Mainnet deployment is in progress.
+</Note>
+
+## Streak milestones
+
+NGZ mints a soulbound NFT each time a user hits a milestone. These NFTs cannot be transferred or burned.
+
+| Days clean | Tier |
+|------------|------|
+| 7 | Novice Resister |
+| 30 | Goon Slayer |
+| 90 | Monk Mode Activated |
+| 180 | Half-Year Warrior |
+| 365 | NGZ Legend |
+
+Relapsing mints a permanent **Fell Off** Wall of Shame NFT in addition to resetting the streak to zero.
