Your AI agent is bleeding money. And you don't even see it.

Every message to your AI agent carries invisible weight. 59,500 tokens of context for a 15 token question. A 4,000:1 ratio. Like reading a novel to answer "what time is it?"
Tokenfesto is the landing page for the Token FinOps movement — a set of seven principles to measure, govern, and design for efficiency in AI agent usage.
| # | Principle | Core Idea |
|---|---|---|
| 1 | Context Is a Resource | Every file loaded pays rent on every API call. Right-size it. |
| 2 | Memory Has Tiers | Hot → Warm → Cold → Archive. Never bulk-load everything. |
| 3 | Budget Guards First | STOP before exceeding $X. Not alert after. |
| 4 | Route by Complexity | Not every task needs Sonnet. Match cost to value. |
| 5 | Audit Monthly | 15 minutes once a month saves $100+. |
| 6 | Steering Over Skills | Skills everywhere is not free. Each manifest pays rent. |
| 7 | Determinism Over Guessing | Validate output against a strict graph, not another LLM. LLM-as-a-judge costs GPU tokens; graph validation costs fractions of a cent. |
