ChatToolCallsComponent

ChatToolCallsComponent renders all tool calls associated with an assistant message. By default sequential same-name calls auto-group into a labeled strip; consumers can register per-tool-name templates via the chatToolCallTemplate directive to fully replace the default card UX.

Selector: chat-tool-calls

Import:

import { ChatToolCallsComponent } from '@threadplane/chat';

Inputs

Input	Type	Default	Description
`[agent]`	`Agent`	— (required)	Source of `agent.toolCalls()`
`[message]`	`Message \| undefined`	`undefined`	Filter to calls referenced by this message's `tool_use` content blocks
`[grouping]`	`'auto' \| 'none'`	`'auto'`	Auto-collapse adjacent same-name calls into a strip
`[groupSummary]`	`(name: string, count: number) => string`	built-in registry	Override the default strip label
`[excludeToolNames]`	`readonly string[]`	`[]`	Tool names whose groups are hidden. Used by chat compositions to filter out internal/orchestration tools (e.g. GenUI dispatchers).

Default group summaries

Tool name shape	Default label
`search_*`	"Searched N sites"
`generate_*`	"Generated N items"
`read_*`	"Read N files"
`write_*`	"Wrote N files"
`list_*`	"Listed N items"
Anything else	"Called N times"

Per-tool templates

<chat-tool-calls [agent]="agent" [message]="msg">
  <ng-template chatToolCallTemplate="search_web" let-call let-status="status">
    <my-search-result-card [query]="call.args.query" [results]="call.result" />
  </ng-template>
</chat-tool-calls>

When a per-tool template is registered for a name, calls of that name skip grouping and are rendered each through the template (the consumer takes responsibility for visual density).

Custom group summary

<chat-tool-calls
  [agent]="agent"
  [message]="msg"
  [groupSummary]="myGroupSummary"
/>

myGroupSummary = (name: string, count: number) =>
  name === 'fetch_user' ? `Fetched ${count} profiles` : `${name} × ${count}`;

Disabling grouping

<chat-tool-calls [agent]="agent" [message]="msg" [grouping]="'none'" />

Each call renders independently regardless of name adjacency.
