feat: Dynamic Details - compact tool output with click-to-expand enhancing navigation and workflow

[ryanwyler]

Summary

Keeps vital tool output compact but fully accessible with a mouse click to quickly view the entire output. Click anywhere on the tool block to expand/collapse making navigating more efficient and easier to follow instead of pages of tool outputs speeding by.

Features

• Tool outputs are compact showing first 15 lines
• Click anywhere to easily expand/collapse
• Configurable threshold via tui.dynamic_details_max_lines (default: 15)
• Configurable arrow indicators via tui.dynamic_details_show_arrows (default: true)
• Toggle via Ctrl+P -> "Enable/Disable dynamic details"
• Persisted in KV store as dynamic_details (default: disabled)

Configuration

{
  "tui": {
    "dynamic_details_max_lines": 15,
    "dynamic_details_show_arrows": true
  }
}

Applies To

Block-container tools (bash, write, edit, patch) when:

• Output exceeds configured line threshold
• Tool has completed (not pending/error states)

Changes

• packages/opencode/src/cli/cmd/tui/routes/session/index.tsx - Add dynamicDetails state, toggle command, and collapse logic in ToolPart
• packages/opencode/src/config/config.ts - Add tui.dynamic_details_max_lines and tui.dynamic_details_show_arrows config options

Rebase Notes

Rebased onto latest dev and updated for API compatibility:

• Updated PermissionRequest.callID to PermissionRequest.tool?.callID (permission API change)
• Added showAssistantMetadata signal (new upstream feature)
• Updated DialogExportOptions.show call to include new parameters

Closing in favor of a cleaner implementation that enhances the existing BlockTool component rather than introducing the ToolRegistry pattern. The new PR maintains the same functionality (click-to-expand/collapse tool outputs) with a much smaller, focused diff that's compatible with current upstream.

The new implementation:

• ~200 lines vs ~1500 lines
• Enhances existing BlockTool instead of replacing tool rendering
• No unrelated changes bundled in
• Works cleanly with current upstream/dev

New PR incoming.
