Sanitizer renames tool names and replaces system prompt patterns that Anthropic fingerprints to detect non-Claude-Code clients. Lowercase tool names (bash, read, glob, etc.) combined together trigger rejection — renaming to PascalCase bypasses this. Configurable via YAML sanitize rules for tools, system, and body. Background OAuth token refresh every 30s with 5-minute pre-expiry lead. Uses Chrome TLS fingerprint for refresh endpoint too. Adds /messages route (without /v1 prefix) for OpenCode compat.
