Developer commentary on VS Code 1.118 and Copilot billing pressure, focused on token efficiency, caching, and agent workflow changes.
Shows token waste becoming a product-design constraint in everyday developer tooling, not just an abstract FinOps concern.
When billing moves closer to actual token burn, IDEs and agents start optimizing prompts, tools, and context loading as first-class work.
Use as commentary rather than a primary release source; pair it with official GitHub or VS Code notes for exact billing details.
