Preview access · not provider authentication
The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of OpenAPI Context Window Packer, so you can see the experience inside your AI.
It does not authenticate your account with OpenAPI Context Window Packer. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ
Questions OpenAPI Context Window Packer owners ask.
- 01
How does the compression work?
The engine uses deterministic pruning. It removes all paths not in your targetEndpoints and then traces $ref pointers to remove any schemas that are no longer reachable, ensuring the resulting spec is structurally valid.
- 02
Will my API specification break after compression?
No. The capability ensures schema integrity by performing a graph traversal. Any component or schema required by your target endpoints is strictly preserved.
- 03
Can I control the size of the output?
Yes. Using compress_openapi_spec, you can set a maxTokenBudget. The engine will iteratively truncate description fields until the specification fits within your specified budget.
