Output
Cost Report
───────────
Phase: <current phase name>
Agent: <agent name> (<tier>)
Tokens: <input> in / <output> out
Est: $<amount>
Session: $<running total>
Budget: $<remaining or unlimited>
Rules
- Report in-line, not as a separate step — cost is metadata, not a task
- Never stop work to report cost unless budget is exceeded
- On budget exceeded: warn, continue, and note the overage
- Track per-agent to identify which agents consume the most
- Use the cheapest tier that works — cost awareness drives routing
