使用说明 (SKILL.md)
Sure — here is the English version with the small change included:
---
name: polymarket-minimal-buy-python
description: Use Python to run a minimal authenticated Polymarket trading client with private key loaded from private.env. Supports initialize/signing auth, market buy/sell, limit buy/sell, open orders, single-order lookup, and order cancellation.
---
# Polymarket Minimal Trading Python
Provide a minimal runnable Python trading client for Polymarket. The private key is loaded from `private.env` and used for authenticated signing.
## Features
- initialize with private key
- market buy / sell
- limit order buy / sell
- auto allowance authorization (USDC for BUY, conditional token for SELL)
- get open orders / get single order
- cancel single / cancel all
- auto create `private.env` if missing, then prompt the user to fill in a MetaMask or other decentralized wallet private key
## Setup
```bash
pip install py-clob-client eth-account
# Auto-create private.env if it does not exist
test -f private.env || cat > private.env \x3C\x3C'EOF'
POLYMARKET_PRIVATE_KEY=
EOF
echo "Created private.env if it was missing. Please open it and paste in the private key from your MetaMask or other decentralized wallet."
Env
Prefer reading private.env from the skill directory, and also support system environment variables.
POLYMARKET_PRIVATE_KEY(required)
Example:
POLYMARKET_PRIVATE_KEY=your_wallet_private_key
Please write the private key from your MetaMask or another decentralized wallet into the private.env file.
Usage
# Market buy
python3 scripts/min_buy.py market-buy --token-id \x3CTOKEN_ID> --amount 10
# Market sell
python3 scripts/min_buy.py market-sell --token-id \x3CTOKEN_ID> --amount 10
# Limit buy
python3 scripts/min_buy.py limit-buy --token-id \x3CTOKEN_ID> --price 0.45 --size 20
# Limit sell
python3 scripts/min_buy.py limit-sell --token-id \x3CTOKEN_ID> --price 0.55 --size 20
# Query orders
python3 scripts/min_buy.py open-orders
python3 scripts/min_buy.py get-order --order-id \x3CORDER_ID>
# Cancel orders
python3 scripts/min_buy.py cancel-order --order-id \x3CORDER_ID>
python3 scripts/min_buy.py cancel-all
A slightly cleaner prompt line for the setup section would be:
echo "Please edit private.env and fill in POLYMARKET_PRIVATE_KEY with the private key from your MetaMask or other EVM-compatible decentralized wallet."
安全使用建议
This skill implements what it claims (a minimal Polymarket trading client) but requires you to provide a private wallet key. Do NOT paste your primary MetaMask or hot-wallet private key into a plaintext file. Consider these precautions before using the skill: 1) Prefer using a dedicated wallet with minimal funds for automated trading or a signing service/hardware wallet rather than dropping a private key into private.env. 2) Inspect and verify the py-clob-client and eth-account packages (source, version, checksums) before pip installing; consider pinning versions. 3) Be aware the registry metadata does not declare the required POLYMARKET_PRIVATE_KEY — treat that as a red flag and confirm expectations with the publisher. 4) Run this in an isolated environment (VM or container) and avoid storing production keys in plaintext. 5) If you cannot supply a private key safely, seek an integration that uses an external wallet connector or server-side signing so secrets are not placed into local files.
功能分析
Type: OpenClaw Skill
Name: autotransactions
Version: 1.0.0
The skill is a Polymarket trading client that requires the user to provide a plaintext wallet private key, which is stored in a local `private.env` file. While the code in `scripts/min_buy.py` correctly implements the official `py-clob-client` SDK and shows no evidence of data exfiltration or intentional malice, the requirement to handle and store raw private keys is a high-risk behavior that could lead to credential theft if the environment is compromised.
能力评估
Purpose & Capability
The name/description and the code match: the script implements authenticated Polymarket trading (market/limit buy/sell, order queries, cancellations) against clob.polymarket.com on chain 137. However, the registry metadata claims no required env vars or primary credential while both SKILL.md and the code require POLYMARKET_PRIVATE_KEY — this mismatch is important because it hides the need to supply a wallet private key.
Instruction Scope
SKILL.md and the script instruct the user to create a private.env and paste in a MetaMask/decentralized-wallet private key. The code reads that file and environment variables and will use the key to derive API creds and sign orders. While this is necessary for the stated trading functionality, it directs collection and local storage of a highly sensitive secret in plaintext and prompts the user to manually enter their private key — a risky practice that should be avoided or clearly warned about.
Install Mechanism
There is no platform install spec (instruction-only), so nothing is automatically downloaded by the skill bundle. SKILL.md tells the user to run 'pip install py-clob-client eth-account' — installing unpinned packages from PyPI is a moderate-risk operation (install-time code runs on the host). The skill does not pin versions or verify package provenance; the user should vet those packages before installing.
Credentials
The code requires a sensitive env var POLYMARKET_PRIVATE_KEY and optionally reads other POLYMARKET_* env vars (host, chain id, signature type, funder). The registry metadata does not declare required env vars/primary credential, so the required secret is not surfaced in the skill metadata. Requesting a wallet private key is expected for a signing client, but the omission from metadata and the instruction to store the key in a plaintext file is disproportionate without strong guidance or safer alternatives.
Persistence & Privilege
The skill is not marked 'always: true', does not request persistence, and does not modify other skills or system-wide settings. Autonomous invocation is allowed (platform default) but not combined with other unusual privileges.
