What does this plugin do?
Polymarket Event Alpha is an event-market trading product built on top of the official Polymarket Plugin and Onchain OS.

It helps users answer a practical question:

“Can I safely consider an event trade now, and which market is actually worth looking at?”

The product is not designed to promise profit, high win rate, or magic prediction. Its core value is improving trading quality before execution. It helps users avoid wrong assets, poor spreads, thin order books, weak directional setups, and invalid live attempts when platform access conditions are not satisfied.

Core capabilities:

readiness check
asset preparation guidance
market quality score
directional edge score
execution feasibility score
Top 3 event-market shortlist
Top 1 plain-language explanation
trade plan
risk check
exit playbook
platform access condition detection and invalid-action blocking
Which commands does it use?
This skill is designed to work with official command names:

polymarket-plugin
onchainos
It does not rely on local wrappers, copied binaries, private wallet files, or development-only relay tools.

Safety considerations
No private keys are handled by the skill.
No wallet seed phrase or local session data is required by the public skill.
The skill does not bypass Polymarket platform access restrictions.
The skill does not default to automatic swap.
The skill does not default to automatic betting.
The skill avoids forcing a YES/NO recommendation when directional edge is weak.
Public documentation does not include private wallet addresses, API keys, local machine paths, or private logs.

中文说明
这个插件是做什么的？
Polymarket Event Alpha 是一个基于官方 Polymarket Plugin 和 Onchain OS 的事件市场交易产品。

它不是“预测之神”，也不承诺收益或胜率。它解决的是用户在 Polymarket 交易前最容易踩坑的问题：

当前到底能不能交易？
钱包和资产是否准备正确？
是否缺 USDC.e、gas 或 setup？
这个市场是不是烂盘口？
价差和流动性是否适合小额执行？
方向优势是否足够？
如果要做，预算、入场价、风控和退出应该怎么安排？
如果平台访问条件不满足，是否应该阻止无效 live 尝试？
