📋 Decision Context

Question:

Session 182 Phase 3: How to implement the tool renderer system (7 components)?

Task: Not specified

🎯 Decision Made

Chosen:

Created 7 components: renderer-utils.ts shared utility, DefaultRenderer (smart fallback), ShellRenderer, BrowserRenderer, ScreenCaptureRenderer, SearchRenderer, DelegationRenderer, and ToolRendererHost dispatcher. All standalone Angular 20+ with signals, OnPush, separate files.

Options Considered:

• No alternatives documented

💭 Reasoning

Each tool type needs specialized rendering: shell commands need exit codes and stdout/stderr blocks, browser tools need URL pills and status badges, search tools need normalized results with score pills, delegation tools need agent badges with status dots. The ToolRendererHost dispatcher maps toolName to the correct renderer using a simple switch. DefaultRenderer serves as smart fallback parsing any JSON output into key-value rows.
