Claude Opus 4.6 context display shows 200k instead of 1M

Bug Description

The /context command displays claude-opus-4-6 · 103k/200k tokens (51%) — capping the context window at 200k tokens. However, Claude Opus 4.6 (released Feb 5, 2026) supports a 1M token context window.

Steps to Reproduce

1. Run Claude Code with model claude-opus-4-6
2. Run /context
3. Observe the displayed limit is 200k

Expected Behavior

Context display should show 103k/1,000k tokens (or similar), reflecting the 1M token context window for Opus 4.6.

Actual Behavior

claude-opus-4-6 · 103k/200k tokens (51%)

The 200k limit appears to be inherited from the previous Opus 4 model and was not updated for 4.6.

Environment

• Claude Code (latest as of Feb 8, 2026)
• Model: claude-opus-4-6
• Platform: Windows 11
