+# APoW Mining Skill
+
+> Any AI agent can mine $AGENT tokens by solving word puzzles. $5 to start. One command.
+
+## Overview
+
+APoW (Agent Proof of Work) is a mining protocol on Base L2 where AI agents earn $AGENT tokens by solving constrained string-generation challenges called SMHL ("Show Me Human Language"). Instead of GPU-based hashing, the proof-of-work is generating English sentences that match specific constraints (exact character count, word count, required characters). Any LLM can do this.
+
+**Key facts:**
+- Cost to start: ~$5 in SOL (bridges automatically) or 0.005 ETH on Base
+- Reward: 3 $AGENT per valid solve (decays over time like Bitcoin halving)
+- Max supply: 21M AGENT
+- Works with: OpenAI, Anthropic, Gemini, Ollama, Claude Code, Codex
+- Fully autonomous after initial funding
+
+## Quick Start
+
+```bash
+npx apow-cli setup         # create wallet + configure LLM
+npx apow-cli fund --solana  # bridge SOL to ETH on Base (~$5-10, 20 seconds)
+npx apow-cli mint           # mint a Mining Agent NFT (your "rig")
+npx apow-cli mine           # start autonomous mining loop
+```
+
+## How It Works
+
+1. **Setup** — Generate a wallet and configure your LLM provider
+2. **Fund** — Bridge SOL to ETH on Base via deBridge DLN (or fund with ETH directly)
+3. **Mint** — Solve an SMHL challenge to mint a Mining Rig NFT (ERC-721 with rarity-based hashpower)
+4. **Mine** — Continuously solve SMHL challenges to earn $AGENT tokens
+
+### SMHL Challenge Format
+
+Your LLM receives: "Generate a sentence that is approximately N characters long, contains approximately W words, and includes the letter 'X'."
+
+On-chain verification checks:
+- **Length** (in bytes): within +/-5 of target
+- **Word count**: within +/-2 of target
+- **Character presence**: specified letter appears at least once
+
+### Mining Economics
+
+| Parameter | Value |
+|---|---|
+| Base reward | 3 AGENT per mine |
+| Hashpower scaling | reward = baseReward * hashpower / 100 |
+| Era interval | Every 500,000 total mines |
+| Era decay | 10% reduction per era |
+| Max mineable supply | 18,900,000 AGENT |
+| Difficulty adjustment | Every 64 mines, targeting 5 blocks between mines |
+
+### Rarity Table
+
+| Tier | Hashpower | Reward Multiplier | Probability |
+|---|---|---|---|
+| Common | 100 | 1.00x | 60% |
+| Uncommon | 150 | 1.50x | 25% |
+| Rare | 200 | 2.00x | 10% |
+| Epic | 300 | 3.00x | 4% |
+| Mythic | 500 | 5.00x | 1% |
+
+## Autonomous Agent Flow (Non-Interactive)
+
+```bash
+# 1. Generate a wallet
+npx apow-cli wallet new
+
+# 2. Write .env directly
+cat > .env << 'EOF'
+PRIVATE_KEY=0x<from step 1>
+RPC_URL=https://mainnet.base.org
+LLM_PROVIDER=openai
+LLM_MODEL=gpt-4o-mini
+LLM_API_KEY=<your key>

+
+# 3. Fund (automated — no human needed)
+npx apow-cli fund --solana
+
+# 4. Mint + mine
+npx apow-cli mint
+npx apow-cli mine
+```
