Controller CLI

Cartridge Controller CLI

Use this skill when you need to run the Cartridge Controller CLI (controller-cli) to create a scoped session (human-approved) and then execute Starknet transactions via that session.

When to Use

• Operating Cartridge Controller sessions with explicit network and least-privilege policies.
• Running controller or controller_safe.py for human-approved Starknet transactions.

When NOT to Use

• General Starknet scripting that does not rely on Cartridge Controller.
• Contract authoring, testing, deployment, or security audit workflows.

Non-Negotiable Rules

• Always pass --json and treat outputs as JSON.
• Always be explicit about network. Never rely on defaults:
  • --chain-id SN_MAIN|SN_SEPOLIA, or
  • --rpc-url <explicit url>.
• controller register requires human browser authorization. Do not automate/bypass it.
• Use least-privilege policies only. Do not add token transfer permissions unless explicitly requested.
• Transaction links: use Voyager only:
  • Mainnet: https://voyager.online/tx/0x...
  • Sepolia: https://sepolia.voyager.online/tx/0x...

Quick Start

curl -fsSL https://raw.githubusercontent.com/cartridge-gg/controller-cli/main/install.sh | bash
export PATH="$PATH:$HOME/.local/bin"
controller --version

Safer Wrapper (Recommended)

This skill includes a small wrapper that enforces the rules above and normalizes output:

python3 scripts/controller_safe.py status
python3 scripts/controller_safe.py register --preset loot-survivor --chain-id SN_MAIN
python3 scripts/controller_safe.py execute 0xCONTRACT entrypoint 0xCALLDATA --rpc-url https://api.cartridge.gg/x/starknet/sepolia

Behavior:

• Adds --json if missing.
• Refuses to run call|execute|register|transaction without --chain-id or --rpc-url.
• Parses stdout as JSON.
• If .status == "error", prints error_code, message, recovery_hint and exits non-zero.

Deterministic Workflow

1) Generate Keypair

controller generate --json

The private key is stored locally (typically ~/.config/controller-cli/).

2) Check Session Status

controller status --json

Common states:

• no_session (no keypair)
• keypair_only (needs registration)
• active (registered and not expired)

3) Register Session (Human Approval Required)

Requirement: a human must approve in a browser.

Option A (preferred): preset policies:

controller register --preset loot-survivor --chain-id SN_MAIN --json

Option B: least-privilege policy file:

controller register --file policy.json --rpc-url https://api.cartridge.gg/x/starknet/sepolia --json

Authorization output includes short_url and/or authorization_url:

• Display short_url if present; otherwise display authorization_url.
• Ask the user to open it and approve.
• The CLI blocks until approved or timeout (typically ~6 minutes).

4) Execute Transaction

Single call (positional args: contract, entrypoint, calldata):

controller execute 0xCONTRACT transfer 0xRECIPIENT,0xAMOUNT_LOW,0xAMOUNT_HIGH \
  --rpc-url https://api.cartridge.gg/x/starknet/sepolia \
  --json

Multiple calls from file:

controller execute --file calls.json --rpc-url https://api.cartridge.gg/x/starknet/sepolia --json

Optional confirmation wait:

controller execute --file calls.json --rpc-url https://api.cartridge.gg/x/starknet/sepolia --wait --timeout 300 --json

5) Read-Only Call (No Session Needed)

controller call 0xCONTRACT balance_of 0xADDRESS --chain-id SN_SEPOLIA --json

6) Transaction Status

controller transaction 0xTX_HASH --chain-id SN_SEPOLIA --wait --timeout 300 --json

7) Lookup Usernames / Addresses

controller lookup --usernames alice,bob --json
controller lookup --addresses 0x123...,0x456... --json

Network Selection

Always be explicit about network.

Supported networks:

Priority order:

1. --rpc-url flag
2. Stored session RPC URL (from registration)
3. Config default (lowest)

If network is ambiguous:

1. Run controller status --json
2. Match the session chain_id, or ask the user

Paymaster Control

Default behavior uses the paymaster (free execution). If the paymaster is unavailable, the transaction fails (no silent fallback).

To self-pay with user funds:

controller execute ... --no-paymaster --json

Amount Encoding (u256)

Many ERC20-style amounts are u256 split into (low, high) u128 limbs.

For values that fit in u128 (most cases): set high = 0x0.

Example calldata: 0xRECIPIENT,0x64,0x0

Error Handling

Errors are JSON:

{
  "status": "error",
  "error_code": "ErrorType",
  "message": "...",
  "recovery_hint": "..."
}

Always branch on error_code and follow recovery_hint.

Common recoveries:

• NoSession: run controller generate --json
• SessionExpired: re-run controller register ... --json
• ManualExecutionRequired: policy does not authorize the call; tighten/adjust policy and re-register
• CallbackTimeout: user did not approve quickly enough; re-run register and retry

Input Validation

Addresses must be 0x-prefixed hex.

python3 scripts/validate_hex_address.py 0xabc...
