Description

### Preflight Checklist

- [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

Environment: Claude Code desktop app (Windows 11), Sonnet 5 for most of the session, switched to Opus 5 at the end. Custom MCP bridge to Autodesk Revit 2026 (IronPython code execution tool).

What happened: One working session (a few hours) editing a roof element in a Revit model — roughly 80 MCP tool calls, several read-only geometry checks per edit, two full rebuilds of one element. By Tuesday afternoon the weekly limit shows ~30% used. Nothing exotic: no web browsing, no large repo indexing, one ~800-line script read once.

Why this matters: Agentic CAD/BIM work is inherently call-heavy: every edit needs a verification round-trip through the API, and tool results (element lists, coordinates) are the actual working data, not noise. With the reduced weekly limits this workflow burns through a week's budget in ~2 days, which makes the product unusable for its best use case.

Acknowledged on our side: part of the burn was avoidable (verbose list dumps, repeated queries). We've since added a helper prelude and stricter output rules. Even so, the remaining necessary volume does not fit the current weekly cap.

### What Should Happen?

Reconsider the weekly cap reduction, or
Don't count (or discount) tool-result tokens from local MCP servers the same as generated output, or
Expose a per-session token meter in the app so users can see the burn rate before the weekly warning.

Research direction

The report names the Claude Code desktop app, a custom MCP bridge to Autodesk Revit 2026, and version 2.1.221, but no repository files, tests, or reproducible steps. Start by examining how weekly usage limits and MCP tool-result accounting are exposed in the app; done would require an agreed cap or accounting change, or a per-session token meter.
