## Tools (5)

- `hypertune_evaluate`: Evaluate one or more feature flags for a given context and get their resolved values. Builds `query { root(context: <context>) { <selection> } }`. Provide `sele
- `hypertune_get_logic`: Fetch the underlying LOGIC of flags without reducing them — i.e. `query { root { <selection> } }` with no context. Returns the flag's conditional expression / r
- `hypertune_introspect`: Run a GraphQL introspection query to discover the project's schema — all types and fields, including the available flags and the shape of the evaluation context
- `hypertune_list_flags`: List the project's top-level feature flags (the fields of the query root type) with their return types and descriptions, derived from GraphQL introspection. A c
- `hypertune_query`: Run an arbitrary GraphQL query (and optional variables) against the Hypertune edge endpoint. Power-user escape hatch for full control — each Hypertune project h
