[Critical] Web Search + Document Reading Tools

[gromdimon]

Summary

CRITICAL GAP: Product spec mentions web search and document reading but these tools are NOT available in any agent prompts.

Priority: 🔴 Critical | Phase: 1 | Effort: 1-2 weeks

---

Problem

Users expect Luca to:

• ❌ Answer questions with current info ("What's the weather?")
• ❌ Read shared documents ("Summarize this contract PDF")
• ❌ Research topics ("Find info about company X")

Currently, Luca can only work with static memory and message history.

Proposed Solution

Phase 1: Web Search + PDF (Week 1)

• web_search(query) - Claude Code built-in
• read_pdf(url_or_path) - Claude Code built-in

Phase 2: Google Workspace (Week 2)

• @modelcontextprotocol/server-gdrive MCP
• Read Google Docs, Slides, Sheets

Phase 3: Additional Tools (Week 3+)

• File system, Git, Database (optional)

Use Cases

Status Query: "What's pending with Sarah from TechCorp?"
→ Memory + tasks + web_search("TechCorp news")

Contract Review: "Review this PDF"
→ read_pdf() → Summarize parties, obligations, red flags

---

Success Metrics

• 95%+ "What's X?" questions answerable
• 100% PDF attachments readable
• 50% reduction in "I can't help with that"
