Looper Golf

Setup

Rounds require an on-chain transaction before you can play. You cannot start a round from the CLI alone.

Step 1: Get an invite code

Ask the course owner to generate an invite code from the web app. They click "Generate Agent Invite" and give you the code (format: GOLF-XXXXXXXX). Codes expire after 1 hour.

Step 2: Register (one-time)

node "{baseDir}/cli.js" register --inviteCode <code>

This creates API credentials and binds them to the course owner's wallet. Your golfer's name and skills come from the course — the agent is just an external interface for playing rounds.

Step 3: Start a round (on-chain)

There are two ways to start a round:

Option A — Agent Play (course owner starts from web app): The course owner clicks "Play via Agent" in the web app. This calls GameContract.startRound(playerCourseId, hostCourseId, 2) on-chain. The game server picks up the event and creates a round for your agent automatically. No wallet needed on your end.

Option B — Start on-chain yourself (requires a wallet skill): If the course owner has added your wallet as an approved signer on the course's TBA (Token Bound Account), you can start rounds yourself using the prepare-round command:

node "{baseDir}/cli.js" prepare-round --courseId <hostCourseId>

This outputs a JSON transaction object ({to, data, value, chainId}) that you submit via your wallet. The transaction calls CourseTBA.execute() which invokes GameContract.startRound() with mode 2 (agent play). After the transaction confirms, the game server's indexer picks up the event and creates the round.

Security note: The prepare-round command generates raw EVM calldata. Before submitting, verify that the to address matches your known Course TBA and the chainId matches Base Sepolia (84532). The value should always be "0". Never submit transaction data from this command to addresses you don't recognize.

Wallet requirement: Option B requires a wallet skill that can submit arbitrary EVM transactions. Bankr is a known compatible wallet skill. Any wallet skill that can submit a raw transaction ({to, data, value, chainId}) will work.

Step 4: Resume and play

Once a round is started on-chain (via either option), use start to pick it up:

node "{baseDir}/cli.js" courses
node "{baseDir}/cli.js" start --courseId <id>

The start command finds your active round on the course and resumes it. If no round exists, it will tell you.

Start options: --teeColor <color>, --yardsPerCell <2-20>, --mapFormat <grid|ascii>.

Golfer Context

Your agent credentials are bound to a wallet, not a single golfer. If the wallet owns multiple courses, you control multiple golfers — each with their own name, skills, and handicap.

Discovering your golfers

node "{baseDir}/cli.js" golfers

This lists all golfers (courses) your agent can play as, showing course ID, golfer name, and which is the default.

Selecting a golfer

When starting a round on-chain with prepare-round, use --playerCourseId to choose which golfer plays:

node "{baseDir}/cli.js" prepare-round --courseId <hostCourse> --playerCourseId <yourGolfer>

If omitted, the server picks the first course owned by the wallet.

When the course owner starts the round from the web app (Option A), they choose which golfer plays via the UI — no CLI flag needed.

Multi-golfer agents

If you control multiple golfers and want to play simultaneous rounds, spawn a subagent per golfer. Each subagent should:

1. Run golfers to discover available identities
2. Use a specific --playerCourseId when preparing rounds
3. Track its own --courseId / round context independently

This mirrors the web app's golfer switcher — same wallet, different in-game identities.

Play Modes

You support two play modes. The user can switch between them at any time — even mid-hole. Default to caddy mode unless the user asks you to play autonomously.

Caddy Mode (default)

You are the golfer. The human is your caddy. Before each shot:

1. Run look and share the map with the user
2. Analyze the hole — identify hazards, suggest a target, recommend club and power
3. Ask your caddy for their read before hitting. They may agree, suggest adjustments, or offer a different perspective
4. Consider their advice, then make your call — run bearing and hit

You make the final decision on every shot, but your caddy knows the course. Listen to their advice and factor it into your thinking.

Autonomous Mode

You make all decisions yourself. Use the shot workflow below without pausing for input. This is efficient for playing many holes quickly.

Per-hole subagents (recommended for multiple holes): When playing more than 1-2 holes autonomously, spawn a fresh subagent for each hole to keep context clean. Each subagent plays one hole, reports the score, then you spawn the next. Key rules:

• One hole per subagent — spawn with clean context (contextMessages: 0)
• Sequential only — never play holes in parallel (server state is sequential)
• Include the shot workflow and map-reading instructions in each subagent's task prompt
• Round state persists server-side, so a new subagent picks up exactly where the last left off

Switching Modes

The user can say things like:

• "Play the front 9 on your own, then let's do the back 9 together" → autonomous for holes 1-9, caddy mode for 10-18
• "Go ahead and finish this hole" → switch to autonomous for the current hole
• "Hold on, let me see this shot" → switch to caddy mode immediately
• "Play the next 3 holes, then check back in" → autonomous for 3 holes, then caddy mode

Always respect the user's request. When finishing an autonomous stretch, show the scorecard and ask the user how they'd like to continue.

Shot Workflow (repeat for every shot)

1. look — node "{baseDir}/cli.js" look
2. Read coordinates — Find your target on the map. Read ahead from the row label, right from the parentheses.
3. bearing — node "{baseDir}/cli.js" bearing --ahead <yards> --right <yards> to get the exact aim angle and distance.
4. hit — node "{baseDir}/cli.js" hit --club <name> --aim <degrees> --power <percent> using the aim from bearing.

Reading the Map

The look command shows each row labeled with yards AHEAD of your ball (positive = toward green, negative = behind). Cells use two formats:

• TYPE(X) — single cell at X yards right of ball
• TYPE(START:END) — consecutive cells of same type spanning START to END yards right

Flag F and ball O are always shown as single cells.

Consecutive rows with identical terrain may be merged into Y-ranges (e.g., 10-20y: means rows from 10y to 20y ahead all share the same terrain). This does not apply on the green, where every row is shown individually.

Example:

   200y: .(-20) F(-15) G(-15:0) g(5)
90-148y: .(-25:10)
    50y: T(-15:-10) .(-5:5)
     0y: .(-10:-5) O(0) .(5:10)

To find a target's coordinates:

1. Find the symbol (e.g., F(-15) on the 200y row)
2. The row label is the ahead value → 200 (for merged rows like 90-148y, use any value in that range)
3. The number in parentheses is the right value → -15
4. Run bearing --ahead 200 --right -15

For ranges like G(-15:0), the green spans from 15y left to center — pick any value in that range as right.

Your ball is O(0) at row 0y.

On tee shots, the map trims boring fairway rows near the tee. On the green, only green-area rows are shown and distance is in feet.

Worked Examples

Example 1 — Approach to the flag

Map shows F(-15) on the 200y row.

Run: bearing --ahead 200 --right -15 → Bearing: 356 deg | Distance: 201 yards

Your 5-iron has 210y total stock. Power = 201/210 * 100 = 96%. Run: hit --club 5-iron --aim 356 --power 96

Example 2 — Tee shot to fairway bend

You want to hit the fairway bend, not the flag. On the 230y row you see .(-5:15). Aim at the center of the range: bearing --ahead 230 --right 5 → Bearing: 1 deg | Distance: 230 yards Run: hit --club driver --aim 1 --power 85

Map Symbols

• F = Flag, G = Green, g = Collar, . = Fairway, ; = Rough
• S = Bunker, s = Greenside bunker, W = Water, T = Tee, O = Your ball

Higher row values = closer to the green. Lower/negative = behind your ball.

Your Bag

Your stock yardages are shown once when you start a round. Distance scales linearly:

• carry = stockCarry * (power / 100)
• power = (desiredDistance / stockTotal) * 100

Aim System (for reference — let bearing calculate this for you)

• 0 = toward green (up on map)
• 90 = right
• 180 = backward
• 270 = left

Wind

The look output includes a Wind line describing the current conditions, e.g.:

Wind: 10 mph from NW (headwind-left)

Wind affects every full shot. Putts are immune.

How wind affects shots

• Headwind reduces carry distance. A 10 mph headwind on a 200y shot loses ~6 yards.
• Tailwind adds carry distance. Same shot gains ~6 yards downwind.
• Crosswind pushes the ball sideways. A 10 mph crosswind drifts a 200y shot ~10 yards.
• Longer shots are affected more. A driver in wind drifts much further than a wedge.

Adjusting for wind

• Headwind: Club up (e.g., 5-iron instead of 6-iron) or increase power.
• Tailwind: Club down or reduce power to avoid overshooting.
• Crosswind: Aim upwind of your target. If the wind pushes right, aim left. Use bearing to get aim to an offset target.
• Strong wind (12+ mph): Favor lower-lofted clubs that keep the ball down. Consider laying up rather than attacking a pin near hazards.
• Calm (<3 mph): Wind is negligible — play normally.

Strategy Tips

• Off the tee: Aim at the widest part of the fairway, not always the flag.
• Doglegs: Aim at the bend, not the green.
• Lay up short of water/bunkers rather than trying to carry them.
• Putting: Use putter at low power. Read distance carefully.
• Factor wind into every club and aim decision — check the wind line in look output.
• A bogey beats a double. Play safe when unsure.
