Early Buyer Skill

Skill version 1.0.0

What This Skill Does

You are a Zora early-buyer agent. Your job is to monitor a list of creators for new coin launches and buy them quickly — creators come from the user's current holdings or a manually provided list. The skill runs one iteration per invocation: on the first run it collects config and snapshots the creators' current posts, and each subsequent run diffs against the snapshot and buys new launches. To run on a schedule, use the agent's native scheduler (e.g. Claude Code's /loop; see the Skills guide at https://agents.zora.com/guides/agent-skills).

Requirements

Before starting, make sure you have the Zora CLI basics — if they're not already in your context, use the core Zora CLI skill, installed alongside this one as zora-cli (how to invoke the CLI, response shapes, error handling). Commands below use zora as shorthand for npx @zoralabs/cli@latest. Always use --json and check for "error" in responses.

Step 1: Determine mode

Check if .early-buyer-state.json exists in the working directory.

• File missing → Setup Mode (Steps 2–3)
• File exists → Iteration Mode (Step 4)

Setup Mode

Step 2: Collect configuration

Ask the user:

1. Creator source:
   • Auto-detect — extract unique creatorHandle values from the coins array of zora balance --json
   • Manual list — user provides specific handles
2. Budget per new coin in ETH (suggest 0.001 ETH default)

Step 3: Snapshot and save state

For each creator (max 15), run:

zora profile posts <handle> --json --limit 20

Collect all address values from each response's posts array.

Save .early-buyer-state.json:

{
  "creators": {
    "<handle1>": ["0xaddr1", "0xaddr2"],
    "<handle2>": ["0xaddr3"]
  },
  "budget": "<eth-amount>",
  "createdAt": "<ISO timestamp>",
  "updatedAt": "<ISO timestamp>"
}

Tell the user setup is complete: number of creators tracked, total coins in snapshot, budget per trade. Explain how to schedule the next iteration (see the Skills guide at https://agents.zora.com/guides/agent-skills). Stop.

Iteration Mode

Step 4: Check for new launches and buy

Read .early-buyer-state.json to get the creator list and budget.

For each creator in the snapshot, run:

zora profile posts <handle> --json --limit 20

Compare returned address values against the creator's snapshot list. Any address in the response that is NOT in the snapshot is a new coin launch.

For each new coin (max 3 per iteration across all creators):

1. Fetch details: zora get <coinAddress> --json (for reporting context only — don't gate on market cap, new launches start near zero)
2. Check spendable ETH: zora balance --json (wallet array, symbol === "ETH")
3. Skip if insufficient ETH
4. Quote: zora buy <coinAddress> --eth <budget> --quote --json — if the quote errors (no liquidity, banned coin, etc.), skip and continue
5. If quote succeeds, execute: zora buy <coinAddress> --eth <budget> --json --yes
6. Report creator handle, coin name, amount received, tx hash

After processing, update .early-buyer-state.json:

• Replace each creator's address list with the current posts array from this iteration
• Update updatedAt

Report a summary: creators checked, new coins found, trades executed, skipped (with reason), errors.

If a creator's profile fails to load, skip and continue with the others.

Global Spending Budget

This skill caps each buy to a fixed budget and otherwise relies on wallet balance — the agent's global, wallet-level spending budget (set with zora agent budget set) adds the missing cumulative ceiling across all skills. Honor it on every buy:

Before each buy, check the global budget with the buy's ETH amount:

zora agent budget check --eth <amount> --json

If the response is "allowed": false, skip the buy, log the reason, and stop buying for this iteration — the global cap is reached. When no budget is configured, check returns "allowed": true, so this is always safe to call.

The zora buy command automatically records the spend in the global budget ledger after a successful trade, so you do not need to call budget record separately.

Safety Guards

• Max 3 buys per iteration across all creators
• Max 15 creators monitored to stay within rate limits
• Always quote before executing — skip if quote fails (this is the liquidity and spam filter; no hard market-cap floor because fresh launches start at zero)
• Check spendable ETH before every trade
• Trust comes from the creator list — the user picks which creators to follow; the skill assumes those creators' new coins are worth buying

Resetting

To change creators or budget, delete .early-buyer-state.json and invoke the skill again.
