@cortexkit/anthropic-auth-core
Internal implementation package for CortexKit's OpenCode and Pi integrations. Apart from the named public surface below, exports are internal host-support APIs with no stability promise.
Public, stable surface
These root exports are public and stable for external callers, including Synapse's Anthropic request client:

The export-manifest test pins these names to the actual root barrel. Legacy sidecar writers and pre-native scoped runtime APIs are removed; host credentials and settings use native storage. Upgrade migration and one-time vault seeding still read the old sidecar format.

Claude Haiku 5.5 (claude-haiku-5-5) has a 1M-token context window and 128K max output. Standard input/output rates are $0.10/$0.50 per million tokens; all rates increase fivefold above 100K total input, including cached tokens. Optional quota priming continues to send a minimal Haiku 4.5 request to start a new quota window.
