feat: expand assistant interaction capabilities

 page layout until it is opened. Users can start, revisit, and delete conversations from the
 conversation menu in the floating panel.
 
+Messages support copy, edit-and-resend, response regeneration and branch navigation, Markdown export,
+helpful/not-helpful feedback, text-to-speech, and browser speech dictation when the browser supports it.
+Selecting text in a message exposes a quote action that carries the selected passage into the next prompt.
+Files returned by a compatible model can be downloaded directly from the message.
+Images up to 1 MB and text, Markdown, CSV, HTML, XML, or JSON documents up to 350 KB can be attached by
+using the paperclip or dropping files onto the composer. A request can contain up to five attachments.
+Image understanding depends on the selected model; document text is extracted locally by Homarr and sent
+as part of the prompt.
+
+Type `@` in the composer to add permission-checked context. The nested menu contains apps, integrations,
+boards, widgets, and tools available to the current user. Homarr validates every referenced ID again on
+the server before adding it to the model context. Type `/` for common prompt shortcuts.
+
+Each completed response includes expandable request details when the provider reports them: input,
+output, cached-input and reasoning tokens, context-window utilization, time to first output, total
+duration, output speed, agent-step timing, and cost. OpenRouter-reported cost is labeled as reported.
+OpenRouter responses also show the routed provider, generation identifier, and upstream inference cost when
+the endpoint supplies those fields.
+When a provider omits cost but model discovery includes prompt and completion pricing, Homarr labels the
+calculated value as estimated. Missing provider data is shown as not reported rather than inferred.
+
 The assistant can use the same internal tool definitions as the [Homarr MCP server](./mcp).
 Each tool call runs as the signed-in user, so normal Homarr permission checks still apply. Read-only
 procedures can run during the agent loop. Mutating procedures require an explicit approval in the
-conversation before they execute.
+conversation before they execute. Tool cards expose their status, timing, validated input, result, and
+error state without flooding the conversation with raw JSON by default.
 
 Homarr also exposes a small set of browser-only actions to the assistant. These actions can navigate to
 safe internal routes and open Homarr interfaces such as the command menu and media request search.
