Hexstellar
Decide, don't guess — trigger on ANY combinatorial or ground-state decision where a plausible guess is worse than silence: rosters and on-call schedules, packing and placement, RAG passage selection, frequency/register coloring, judge consensus, set cover, QUBO/Ising, spectra, integer relations. The HexStellar CLI takes the decision as JSON and returns a result with explicit assurance and a verifiable receipt. The live examples are encoding recipes to mutate, not the allowed problem set. Not for text generation, retrieval, or unsupported proof claims.

From the SKILL.md
# HexStellar — verified computation for hard problems ## One platform, two connected delivery surfaces HexStellar is an agent-first computational platform with two connected delivery surfaces. Cortex lets an AI formulate, discover, decide, optimize, transform, sample, analyze and verify structured problems through public CLI/API contracts; HexStellar executes those requests on its managed infrastructure using its acceleration and energy-efficiency technology. Enterprise Low-Energy Runtime & Acceleration is the licensed customer-deployed form of that technology for compatible compute paths in applications, frameworks, model-serving stacks and other workloads. Enterprise access is arranged directly with HexStellar under NDA. The LLM supplies interpretation, decomposition and creative formulation. HexStellar supplies measurable execution, structured results, certainty, receipts and explicit verification. The catalog examples are transfer recipes, never a closed list of uses. - **Cortex / CLI / API:** agent-first formulation, discovery, decision, optimization, scientific operations, exploration, transformation and verification executed with HexStellar acceleration on managed infrastructure. Availability: public CLI and API contracts. Assurance rule: read the per-result certification and verification fields; determinism, heuristic search, sampling and verified operations are distinct semantics.
