v1.23.0

Highlights

Claude Opus 5.5 support (claude-opus-5-5): 1M context window, 128K max output, native adaptive effort variants (low through max) in OpenCode and Pi, always-on adaptive thinking per Anthropic's spec, fast mode, and refusal-recovery parity with Opus 5.

Claude Code 2.1.280 client identity: request fingerprint (User-Agent, billing header) updated to match Anthropic's Opus 5.5-capable release.

Zero-bind Claustrum custody for OpenCode and Pi: vault accounts added via ck auth login --provider anthropic are discovered automatically within seconds — no capability handles, no manifest edits, no restarts. Per-dispatch scoped authorization, atomic roster reconciliation, and version-fenced 401 reporting.

One-step setup wizard: bunx @cortexkit/opencode-anthropic-auth setup detects OpenCode, Pi, and Claustrum, installs both integrations, and automates custody enrollment, grants, and activation behind a host-quiescence fence.
