Client Tool presentation plugin. ui-conversation dispatches each ordered tool-call Conversation Node through the matching key of conversation.chat.node; this package renders its root and Code Dispatch children, then dispatches every atomic call through the keyed tool.call.toolview slot. Unregistered Tool names use the generic card.

Business UI packages register only their wire Tool names and atomic views. They do not pair Session events, rebuild the transcript, or own root/subcall topology. The Runtime remains authoritative for call/result pairing, lifecycle, and recursive subCalls projection; the conversation view remains authoritative for ChatFlow placement.

Rendering contract

ToolCallTree receives one root ToolCallBlock that already contains recursive subCalls, selection state, the session cwd, and Host callbacks for opening files and inspecting calls. It recursively walks the standard call blocks and sends the root and children at every depth through the same atomic dispatch path, without subscribing to a separate parent-to-children map.

Each root and child wrapper preserves the data-chat-anchor-key="call:<id>" and data-chat-call-id DOM contract used for paging and selection.

The package also fills conversation.details.tool with ToolDetails. The row and details renderers share the same pure card models for terminal, read, diff, search, and web render intents. Unknown intent tags and malformed wire card data fall back to flattened Tool result text.

Generic rows classify known Tool names into search, read, shell, write, edit, code, or generic variants. Running, successful, failed, and interrupted lifecycle states come only from the frozen call/result slice. File paths resolve against the session cwd only when the user invokes the Host open-file callback; presentation code does not read Session services.

Atomic Tool views

An owning business package registers its wire Tool name into tool.call.toolview:

ctx.slots.inject('tool.call.toolview', () =>
  ctx.slots.register({
    name: 'tool.call.toolview',
    key: '<wire tool name>',
  }, BusinessToolRow))

The owner payload is ToolCallOwnerProps: callId, toolName, the frozen block, optional cwd, and plain openFile/inspect callbacks. The registration receives the normal session slot runtime share. It does not receive React nodes, Runtime services, or root/subcall knowledge.

This package currently owns the generic fallback and the built-in shell/pwsh, read, write/edit, grep/glob, web, todo, question, and Code Dispatch presentations. ui-skill demonstrates a business-owned registration for skill.

Card-specific limits and fallback rules remain in the owning terminal, diff, read, search, and web notes.

Model Experience

None, as this package renders already logged Tool calls and results without altering model requests, Tool execution, or session events.

KV Cache effect

None. The package is client-only presentation.

Known Limitations and Deferred Work

• The Host excludes run_code from Code Mode program bindings, so production events produce one dispatch level; the recursive Runtime/UI contract supports nesting.
• First-party Tool views are colocated here and can move to their owning business packages independently through the keyed slot.
• Tool copy reuses the ui-conversation locale namespace.
