Opus 4.7 confirmed compatible — no changes needed

[cnighswonger]

Claude Opus 4.7 is available in Claude Code v2.1.111. We tested the interceptor (v1.11.0+) and confirmed full compatibility:

• Fingerprint salt and indices: unchanged
• Interceptor loads and applies all fixes (relocation, tool sort, TTL injection, image strip)
• Cache hit rate: 100% on second call in test
• No fingerprint safety blocks
• Pricing: same as Opus 4.6 ($5/$25 input/output, same cache multipliers)

No interceptor update required. Install the latest and it works out of the box:

npm install -g claude-code-cache-fix@latest

To use Opus 4.7, update Claude Code and select the model:

npm install -g @anthropic-ai/claude-code@latest

Then select claude-opus-4-7 via /model in your session.

We'll report on multi-turn cache behavior and any differences from 4.6 as we accumulate data.
