Near-expiry conviction trading on Polymarket. Snipe markets about to resolve when the odds are heavily skewed. Filter by topic, cap your bets, and only trade...
安全使用建议
This skill does what it claims (a Polymarket expiry-sniper) and legitimately needs a Simmer API key; however it also asks you to place a wallet private key into an environment variable for live trading — that is high-risk. Before using live: 1) Run in dry-run mode only until you’ve inspected behavior and logs. 2) Review the simmer-sdk package source and the included code (mert_sniper.py, scripts/status.py) yourself or with a developer you trust. 3) Prefer managed or delegated signing (hosted/managed wallets or an external signer) rather than dropping a raw private key into an env var; if you must use a key, use a wallet with minimal funds. 4) Note the manifest inconsistencies (missing required envs in registry summary; mismatched env var names like SIMMER_MERT_MAX_BET vs SIMMER_MERT_MAX_BET_USD) — confirm which variables the running code actually reads to avoid misconfiguration. 5) Avoid disabling safeguards (--no-safeguards) and limit max bet/permissions while testing. If you are not comfortable with storing private keys or verifying the SDK, do not run --live.
功能分析
Type: OpenClaw Skill
Name: polymarket-mert-sniper
Version: 1.2.2
The skill bundle facilitates automated trading on Polymarket but requires the user to provide a highly sensitive `WALLET_PRIVATE_KEY`, which `SKILL.md` explicitly instructs the AI agent to solicit and store in environment variables. While the logic in `mert_sniper.py` and `scripts/status.py` appears aligned with the stated purpose of market sniping, the handling of raw private keys and the reliance on an external dependency (`simmer-sdk`) for transaction signing represents a high-risk security pattern. No explicit evidence of data exfiltration or intentional malice was found in the provided code, but the credential solicitation via prompt instructions warrants a suspicious classification.

Purpose & Capability
The code and SKILL.md implement a Polymarket sniping tool and legitimately need a Simmer API key and (optionally) a wallet private key for live trading; network calls target simmer.markets and clob.polymarket.com which align with the stated purpose. However there are packaging/metadata mismatches: the registry summary at the top of the evaluation claimed no required env vars/primary credential, while clawhub.json and SKILL.md clearly require SIMMER_API_KEY (primary) and optionally WALLET_PRIVATE_KEY. Also tunable/env var names differ across files (e.g., SIMMER_MERT_MAX_BET vs SIMMER_MERT_MAX_BET_USD), which is incoherent and may cause confusion at runtime.
Instruction Scope
Runtime instructions explicitly tell users to store their WALLET_PRIVATE_KEY in an environment variable for live trading and to run pip install simmer-sdk; the code and scripts then use those env vars. Asking for and storing raw private keys in env is within the scope of a trading skill but is sensitive. The SKILL.md also allows disabling safeguards (--no-safeguards), which could reduce protections. There are no instructions or code paths that attempt to read unrelated system files or reach unexpected external endpoints, but the explicit guidance to save a private key in environment variables is a notable risk vector if you do not fully trust the SDK and code.
Install Mechanism
No high-risk download URLs are present; dependencies rely on a pip package (simmer-sdk) which is appropriate for a Python SDK. The repository has no explicit platform-level install script in the top-level install spec, but clawhub.json and SKILL.md both reference pip installing simmer-sdk. Using a public pip package is moderate risk — verify the simmer-sdk package source and version (>=0.11.1) before installing.
Credentials
Requested secrets map to the skill's purpose: SIMMER_API_KEY is expected and declared as primary in clawhub.json. WALLET_PRIVATE_KEY is optional but SKILL.md guides users to store it for client-side signing. Requiring a wallet private key (even optionally) is proportionate for live trading but is high sensitivity: exposing it allows full control of funds in that wallet. Additionally, there are inconsistencies in environment variable names across SKILL.md, config schema, and clawhub.json which could cause misconfiguration and inadvertent exposure of credentials.
Persistence & Privilege
The skill is not always: true, autostart is false, and model invocation is not disabled (normal). Automaton.managed is set to true with an entrypoint, which is consistent with an automatable trading skill. There is no evidence the skill attempts to modify other skills or persist beyond its own config files.
