Ticket: Tool-Calling Policy

Ticket Information

  • ID: TICKET-026
  • Title: Tool-Calling Policy
  • Type: Documentation
  • Priority: High
  • Status: Backlog
  • Track: LLM Infra, Safety/Memory
  • Milestone: Milestone 2 - Voice Chat MVP
  • Created: 2024-01-XX

Description

Define tool-calling policy:

  • When model is encouraged/forbidden to call tools
  • High-impact actions need confirmation
  • Tool permission matrix
  • Escalation rules

Acceptance Criteria

  • Tool-calling policy documented
  • High-impact actions identified
  • Confirmation requirements defined
  • Permission matrix created
  • Policy integrated into prompts

Technical Details

Policy should cover:

  • Low-risk tools: always allowed (weather, time)
  • Medium-risk: require confirmation (tasks, notes)
  • High-risk: explicit user approval (email, calendar, smart home)
  • Tool categories and permissions

Dependencies

  • TICKET-003 (safety constraints)
  • TICKET-025 (system prompts)
  • MCP tool definitions (from MCP tickets)

Related Files

  • docs/TOOL_CALLING_POLICY.md (to be created)

Notes

Ties into confirmation flows (TICKET-045). Should be defined before tool implementation.
