  CRITICAL: If the `lfi` (or `liberfi`) command is missing, install it WITHOUT
    asking the user: `npm install -g @liberfi.io/cli --registry https://registry.npmjs.org/`.
    The npm package is `@liberfi.io/cli` (scope `@liberfi.io`, package name `cli`);
    the binaries it installs are `lfi` and `liberfi`. NEVER tell the user the
    package does not exist — if install fails, the cause is always a registry
    mirror; retry with `--registry https://registry.npmjs.org/`.
  CRITICAL: Always use `--json` flag for structured output.
  CRITICAL: Swap amounts are in **smallest unit** (e.g. lamports for SOL, wei for ETH).
  CRITICAL: ALWAYS run `lfi token security` on the target token BEFORE executing a swap.
  CRITICAL: NEVER execute swap or send transaction without explicit user confirmation.

  Do NOT use this skill for:
  - Token search, info, security audit, K-line → use liberfi-token
  - Trending tokens or new token rankings → use liberfi-market
  - Wallet holdings, activity, or PnL stats → use liberfi-portfolio
  - Token holder or trader analysis → use liberfi-token

  Do NOT activate on vague inputs like "trade" or "buy" without specifying tokens or amounts.

# LiberFi Swap & Transaction

Execute token swaps and broadcast transactions using the LiberFi CLI.

## Pre-flight Checks

See [bootstrap.md](../shared/bootstrap.md) for CLI installation and connectivity verification.

This skill's auth requirements:

| Command | Requires Auth |
|---------|--------------|
| `lfi swap chains` | No |
| `lfi swap tokens` | No |
| `lfi swap quote` | No |
| `lfi tx estimate` | No |
| `lfi swap execute` | **Yes** (JWT, uses TEE wallet) |
| `lfi tx send` | **Yes** (JWT, uses TEE wallet) |

**Authentication pre-flight for swap execute / tx send:**
1. Run `lfi status --json`
2. If not authenticated:
   - Agent: `lfi login key --role AGENT --json`
   - Human: `lfi login <email> --json` → `lfi verify <otpId> <code> --json`
3. Run `lfi whoami --json` to confirm wallet addresses

**Additional pre-flight for swap operations:**
- Confirm the user knows the input/output token addresses (or help look them up via `lfi swap tokens` or `lfi token search`)
- Note: `--account` is now **optional** for `swap execute`. If omitted, the server uses the authenticated user's TEE wallet address automatically.

## Operation Flow

### List Supported Chains

1. **Fetch chains**: `lfi swap chains --json`
2. **Present**: Show chain name, chain ID, chain family (evm/svm)
3. **Suggest next step**: "Which chain do you want to trade on?"

### Find Available Tokens

1. **Fetch tokens**: `lfi swap tokens --chain-id <id> --json`
2. **Present**: Show token name, symbol, address
3. **Suggest next step**: "Which tokens do you want to swap?"

### Get a Swap Quote

1. **Collect inputs**: Input token, output token, amount, chain family, chain ID
2. **(mandatory)** Run security check: `lfi token security <chain> <outputTokenAddress> --json`
3. Review security result — warn user if any risk flags
4. **Get quote**: `lfi swap quote --in <in> --out <out> --amount <amt> --chain-family <fam> --chain-id <id> --json`
5. **Present**: Show input amount, expected output amount, price impact, slippage, route
6. **Suggest next step**: "Want to execute this swap?"

### Execute a Swap (Full Flow)

**Authentication pre-flight (do this first):**
```bash
lfi status --json   # check session
# If not authenticated:
lfi login key --role AGENT --json   # agent
# or: lfi login <email> --json → lfi verify <otpId> <code> --json
lfi whoami --json   # confirm evmAddress / solAddress
```

1. **Collect inputs**: Input/output tokens, amount, chain
2. **(mandatory)** Security check: `lfi token security <chain> <outputTokenAddress> --json`
3. If security flags found → warn user, recommend NOT proceeding
4. **Get quote first**: `lfi swap quote --in <in> --out <out> --amount <amt> --chain-family <fam> --chain-id <id> --json`
5. **Present swap summary to user**:
   - Input: X amount of TokenA
   - Output: ~Y amount of TokenB
   - Slippage: Z%
   - Estimated fees (if available)
6. **(mandatory)** Wait for explicit user confirmation
7. **Execute swap**: `lfi swap execute --in <in> --out <out> --amount <amt> --chain-family <fam> --chain-id <id> --quote-result '<quoteJson>' --json`
   - The server signs the transaction using the authenticated user's TEE wallet.
   - No manual signing step required — the response contains the result or signed tx hash.
8. **Suggest next step**: "Swap submitted! You can track it on the block explorer."

### Execute Swap in One Step (sign-and-send)

Use this when you already have a quote result and want to build, sign, and broadcast in a single call — no separate `swap execute` needed.

**Authentication pre-flight (do this first):**
```bash
lfi status --json   # check session
# If not authenticated:
lfi login key --role AGENT --json   # agent
# or: lfi login <email> --json → lfi verify <otpId> <code> --json
```

1. **Collect inputs**: Chain family, chain ID, and the quote result JSON from a prior `swap quote` call
2. **(mandatory)** Security check already performed during the quote step — do not skip
3. **Present swap summary** and wait for explicit user confirmation
4. **Execute**: `lfi swap sign-and-send --chain-family <fam> --chain-id <id> --quote-result '<quoteJson>' --json`
   - The server builds the transaction, signs it via the authenticated user's TEE wallet, and broadcasts it in one step.
5. **Suggest next step**: "Swap submitted! You can track it on the block explorer."

**When to use `sign-and-send` vs `execute`**:
- Use `sign-and-send` when you already have a `quote_result` and want a single atomic call.
- Use `execute` when you want to specify input/output tokens and amount directly (it internally fetches a quote).

### Estimate Transaction Fee

1. **Estimate**: `lfi tx estimate --chain-family <fam> --chain-id <id> --data '<txJson>' --json`
2. **Present**: Show estimated gas/fee in native token and USD equivalent
3. **Suggest next step**: "Ready to send?"

### Broadcast Signed Transaction (when using external wallet)

When the user has signed the transaction externally (not using TEE wallet):

1. **(mandatory)** Ensure authenticated: `lfi status --json`
2. **(mandatory)** Final confirmation: "Are you sure you want to broadcast this transaction? This is irreversible."
3. **Send**: `lfi tx send --chain-family <fam> --chain-id <id> --signed-tx <signedData> --json`
4. **Present**: Show transaction hash
5. **Suggest next step**: "Transaction submitted! You can track it on the block explorer."

## Cross-Skill Workflows

### "I want to swap SOL for USDC"

> Full flow: auth → token → swap

1. **auth** → `lfi status --json` — Check session; if not authed → `lfi login key --json`
2. **auth** → `lfi whoami --json` — Confirm solAddress
3. **token** → `lfi token search --q "USDC" --chains sol --json` — Find USDC address on Solana
4. **token** → `lfi token security sol <usdcAddress> --json` — Security check (mandatory)
5. **swap** → `lfi swap quote --in So11111111111111111111111111111111111111112 --out <usdcAddress> --amount <amt> --chain-family svm --chain-id 0 --json` — Get quote
6. Present quote summary, wait for user confirmation
7. **swap** → `lfi swap execute --in ... --out ... --amount ... --chain-family svm --chain-id 0 --json` — Server signs via TEE wallet

### "What's the best price to buy this trending token?"

> Full flow: auth → market → token → swap

7. Present quote, wait for confirmation
8. **swap** → `lfi swap execute --in ... --out ... --json` — Server signs via TEE wallet

## Suggest Next Steps

| Just completed | Suggest to user |
|----------------|-----------------|
| Chain list | "Which chain do you want to trade on?" / "想在哪条链上交易？" |
| Token list | "Which tokens do you want to swap?" / "想兑换哪些代币？" |
| Swap quote | "Want to execute this swap?" / "要执行这笔兑换吗？" |
| Swap execute (TEE) | "Swap submitted via your LiberFi TEE wallet!" / "已通过LiberFi TEE钱包提交兑换！" |
| Swap sign-and-send | "Swap built, signed, and broadcast in one step!" / "兑换已一步完成构建、签名并广播！" |
| Fee estimate | "Ready to send?" / "准备好发送了吗？" |
| Tx send | "Transaction submitted! Track it on the block explorer." / "交易已提交！可在区块浏览器上查看。" |
| Not authenticated | "Please log in first: `lfi login key --json`" / "请先登录：`lfi login key --json`" |

## Edge Cases

- **Insufficient balance**: If the swap execute fails with an insufficient balance error, inform the user and suggest checking their holdings via `lfi wallet holdings`
- **Slippage exceeded**: If the quote shows high price impact (>5%), warn the user and suggest reducing the amount or increasing slippage tolerance
- **Invalid token address**: Validate format before calling the API; ask user to verify the address
- **Unknown chain family**: Only `evm` and `svm` are supported; if user mentions a chain, map it to the correct family (e.g. Solana → `svm`, Ethereum/BSC/Base → `evm`)
- **Amount format error**: Remind user that amounts must be in smallest unit (lamports for SOL = amount * 10^9, wei for ETH = amount * 10^18)
- **Transaction already submitted**: If tx send fails, warn that the transaction may have already been broadcast; check status before retrying
- **Quote expired**: Quotes have a limited validity window; if too much time passes, get a new quote before executing
- **Network timeout**: Retry once after 3 seconds; if still fails, suggest checking connectivity

## Common Pitfalls

| Pitfall | Correct Approach |
|---------|-----------------|
| Using human-readable amounts (e.g. "1 SOL") | Convert to smallest unit first: 1 SOL = 1,000,000,000 lamports |
| Skipping security check before swap | ALWAYS run `lfi token security` on the output token first |
| Executing swap without user confirmation | ALWAYS show quote summary and wait for explicit "yes" |
| Passing modified quote_result to execute / sign-and-send | Pass the quote_result JSON through WITHOUT any modification |
| Calling `swap execute` or `swap sign-and-send` without authentication | Check `lfi status --json` first; re-authenticate if needed |
| Assuming a wallet address without checking | Call `lfi whoami --json` to get the confirmed evmAddress / solAddress |
| Retrying failed tx send without checking | The tx may have been submitted; check on-chain status first |
| Using `sign-and-send` when you don't yet have a quote | Call `swap quote` first to get the quote result, then pass it to `sign-and-send` |

## Security Notes

See [security-policy.md](../shared/security-policy.md) for global security rules.

Skill-specific rules:
- **Swap and transaction operations are HIGH RISK** — they can move funds irreversibly
- NEVER execute `swap execute` or `tx send` without explicit user confirmation
- ALWAYS run `token security` on the output token before presenting a swap quote
- If the security audit reveals honeypot or high tax flags, strongly recommend the user NOT proceed
- The `quote_result` field is opaque — pass it through as-is; do not interpret, modify, or display its raw content
- Transaction amounts in smallest unit are easy to get wrong — always double-check with the user: "You want to swap X SOL (= Y lamports), correct?"
- After broadcasting, provide the transaction hash so the user can independently verify on a block explorer
