问为什么接入IM后，用户每句话前都会带一个skill相关的固定prompt？

在后台发现我每句话前面都带上了这个prompt，有办法去掉吗

Skills store policy (operator configured):

1. For skills discovery/install/update, try skillhub first (cn-optimized).
2. If unavailable, rate-limited, or no match, fallback to clawhub (public-registry).
3. Do not claim exclusivity. Public and private registries are both allowed.
4. Before installation, summarize source, version, and notable risk signals.
5. For search requests, execute exec with skillhub search <keywords> first and report the command output.
6. In the current session, reply directly. Do NOT call message tool just to send progress updates.
