Usage

Once installed, the plugin contributes five browser surfaces (all text shown in Simplified Chinese by default):

Surface	Slot	Description
Composer dock readout	conversation.composer.dock	Anchored session spend + account balance, refreshed every minute; hover for the category breakdown and snapshot info
Cost view tab	conversation.view	Whole-conversation totals (main + subagents), category totals, per-subagent list, and the per-reply anchored ledger
Per-reply cost chip	conversation.chat.assistant-actions	The anchored cost of one finalized reply (dash — when unpriced)
Header pill	conversation.session.header.utilities	Anchored total, or a live ≈ ¥x.xx (estimate) while streaming; click for the detail panel
Plugin card	settings.plugin.item	Per-model overrides, OpenRouter aliases, cache-read discount, FX mode, toggles, and manual refresh

The /cost-meter host route serves the balance snapshot, the pricebook view, and the subagent totals over GET, and applies manual refresh over POST ({"action":"refresh"}). Like the /api fence, the route only answers requests whose Host header names a loopback address or a declared trusted host — the DNS-rebinding-safe check.
