- Added competitive positioning section with data comparison table,
  speed advantages, and unique features
- Table trimmed to GMGN vs Others (2 columns) for clarity
- Speed section rewritten around real-time data, token analytics keywords,
  trade latency (<0.3s), and explicit K-line/trending granularity

+## Why GMGN Skills
+
+> Purpose-built for on-chain alpha — not a DeFi dashboard, not a general portfolio tracker. GMGN Skills gives AI agents access to the same professional data used by top traders on GMGN.
+
+### Data that competitors don't have
+
+| Capability | GMGN Skills | Others |
+|-----------|:-----------:|:------:|
+| Smart Money historical P&L + win rate | ✅ | ❌ |
+| Smart Money convergence signal (≥3 wallets / 30 min) | ✅ | ❌ |
+| Wallet archetype tags (bundler / rat_trader / sniper / KOL / whale) | ✅ | Partial |
+| Rug ratio score (0–1) + honeypot + wash-trade detection | ✅ | Basic only |
+| Bonding curve lifecycle (pre-grad → graduated → open DEX) | ✅ | Partial |
+| 1-minute K-line (OHLCV) | ✅ | ❌ |
+| Strategy orders: take-profit / stop-loss | ✅ | ❌ |
+| Sell by position percentage (`--percent 50`) | ✅ | ❌ |
+| Follow-wallet live feed with size/direction filters | ✅ | ❌ |
+
+### Built for speed
+
+- **Real-time trading data** — Prices, swap counts, buy/sell volume, and market cap update in real time across SOL / BSC / Base. No stale snapshots.
+- **Real-time token analytics** — Every query returns live-computed values for smart money count (`smart_degen`), KOL positions (`renowned`), rat trader ratio (`rat_trader_amount_rate`), bundler bot exposure (`bundler_trader_amount_rate`), sniper wallet count, suspected insider hold rate, and fresh wallet ratio — the same deep signal layer as the GMGN web platform.
+- **Trade execution** — Shares the same RPC routing as GMGN's web trading interface. Order submission latency under 0.3 seconds.
+- **Real-time data granularity**
+  - **K-line** (`market kline`): `1m` / `5m` / `15m` / `1h` / `4h` / `1d` — minimum **1-minute** candles, live-updated
+  - **Trending list** (`market trending`): `1m` / `5m` / `1h` / `6h` / `24h` — minimum **1-minute** window, refreshed every cycle
+
+### Only on GMGN
+
+- **Smart Money convergence** — Surfaces tokens where ≥ 3 Smart Money wallets traded the same direction within 30 minutes — the strongest early-entry signal available.
+- **Full wallet P&L breakdown** — Per-wallet realized profit, unrealized profit, average buy/sell price, win rate, and trade style profile. Know exactly how good a wallet is before you follow it.
+- **Copy-trade estimation** — `workflow-smart-money-profile.md` calculates the historical return if you had mirrored a wallet trade-for-trade.
+- **Multi-dimensional wallet tags** — Every holder is classified: smart_degen, renowned, sniper, rat_trader, bundler, whale, fresh wallet. No other skill exposes this.
+- **9 built-in AI workflows** — Token research, project deep report, wallet analysis, smart money profiling, risk warning, early project screening, daily brief, market discovery, and more — all wired to the CLI.

+- **交易速度** — 与 GMGN 网页端共享同一套 RPC 路由，瞬间下单，提交延迟小于 0.3 秒。
+- **实时数据粒度**

+- **多维钱包标签体系** — 每个持币地址都有分类标签：聪明钱 / 知名 / 狙击手 / 老鼠仓 / Bundler / 巨鲸 / 新钱包。没有其他 Skill 暴露这层数据。
+- **9 个内置 AI 工作流** — 代币研究、项目深度报告、钱包分析、聪明钱画像、风险预警、早期项目筛选、每日简报、市场发现等，全部与 CLI 直连。
