Skill: Token Tracker + Budget Enforcement

Purpose

Track and display token consumption and cost for every NetClaw interaction. Enforce per-session spending caps and tool-call depth limits to prevent runaway API costs. Serialize MCP server responses in GCF format to reduce token usage by 40-60% on tabular network data.

What This Prevents

Without this skill, a single casual phone question can trigger unbounded agentic tool chains that silently burn $10+ in API costs. This skill ensures:

• Sessions halt at a configurable cost ceiling (default: $5)
• Tool-call chains pause after N calls per question (default: 20)
• The operator sees what was accomplished and can choose to continue
• Budget status is visible in every response footer
