Tokens, turns and time describe resource use, not a dollar price.
One of 14 test cases the skill fixed. Same model, same prompt, with and without the skill.
Which environment variable can an engineer set to force a $2.00 session budget ceiling without modifying openclaw.json?

| Identifies NETCLAW_SESSION_BUDGET_USD variable | Missed | Passed |
The instructions your model reads when the skill loads.
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.
Without this skill, a single casual phone question can trigger unbounded agentic tool chains that silently burn $10+ in API costs. This skill ensures:
