📋 Decision Context

Question:

Why were Vitto chat tools and computer use pre-set processes not working?

Task: Fix missing computer use processes and tool support in Vitto chats

🎯 Decision Made

Chosen:

Expanded channelSafeTools with 14 missing tools (OAuth, computer use supervised, web search, messaging, domains), broadened INTENT_TOOL_MAP unknown fallback to include integrations+browser categories, and replaced silent error swallowing on profiles load with visible error feedback

Options Considered:

Approach A: Surgically expand channelSafeTools + intent map (chosen)
Approach B: Remove channelSafeTools entirely and rely on layer filtering (rejected — too broad, 30+ tools confuse the LLM)

💭 Reasoning

channelSafeTools was never updated as new tool plugins were added across sessions 140-285. Tools like oauth_api_call, start_computer_use, web_search, manage_group etc. were registered as plugins with proper layer access but excluded from the hardcoded channelSafeTools whitelist used by the channel processing agent loop. The web streaming path (INTENT_TOOL_MAP) also defaulted to categories that excluded integrations and browser tools. Computer use profiles not showing was a runtime issue (backend-ai-api unreachable) masked by silent catchError(() => of([])).
