v1.1.2

What's Changed

• Added /claude-cachekeep for hybrid Claude cache mode. It keeps in-memory clones of recently used rewritten requests and sends prewarm-safe max_tokens: 0 calls during the configured local time window.
• Fixed OAuth refresh backoff after re-login by resetting retry severity when the refresh token rotates.
• Reduced hidden slash-command reply overhead by bounding OpenCode prompt-context lookup to the most recent 100 messages instead of hydrating the full session.

Published packages

v1.1.0

Highlights

• Added /claude-fast on|off for supported Opus models, enabling Anthropic fast mode with persisted configuration.
• Aligned Anthropic request headers/body shape more closely with Claude Code 2.1.141, including Claude CLI/Stainless headers, request-shape-aware beta selection, body key ordering, and bootstrap-backed account metadata.
• Improved hybrid 1-hour cache mode with explicit anchors on the final stable system block, messages[0], messages[1], and a moving near-tail anchor for long sessions.

Relay reliability and performance

• Made WebSocket relay startup more responsive with optimistic SSE responses, binary chunk frames, and deferred Worker checkpoint/KV work.
• Added automatic WebSocket reconnect + one-time full_sync retry when the socket closes before upstream response bytes are emitted.
• Added Worker-side body hash verification before forwarding reconstructed requests upstream.
• Kept relay affinity/session headers internal so they are not forwarded to Anthropic.
• Accepted both /v1/messages and /messages upstream paths for Anthropic SDK/custom-baseURL traffic.

Auth and compatibility fixes

• Proactively refresh the main OpenCode Anthropic OAuth token in the background instead of waiting for the next Claude request after idle time.
• Reverted OAuth refresh to the known-working platform JSON endpoint after live console-endpoint refreshes returned 429.
• Fixed chunk-safe stripping of Claude-Code-style mcp_* tool names from streaming Anthropic responses.

Testing and release infrastructure

• Added OpenCode e2e coverage using a real opencode serve subprocess, mock Anthropic server, and mock protocol-v2 WebSocket relay.
• Added Miniflare/workerd coverage for the embedded Cloudflare Worker with KV and WebSocket upgrades.
• Hardened npm Trusted Publishing by publishing each package in a separate OIDC job and skipping already-published package versions during recovery.
