Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢changes_list(store, region, since, apps, types, ...)
Use this when the user asks what changed in a store: chart moves, featuring, launches, delistings, metric moves or MCP changes, newest first with counts per type. Do not use for a chart's full current order; use charts_get.

}🟡feedback_send(issue, summary, initiator, details, tool, ...)
Use this when OpenApps' tools or data fail the user: an error, data the user says is wrong (such as an app bound to the wrong listing), a missing capability, or something confusing. Ask the user before sending a report they did not ask for. It is stored privately with the caller's account and client; no reply comes in this conversation. Summarize; never include secrets or personal data. Do not use for other servers or the client app; it does not finish the user's task.
