What it does
Hexstellar is an agent skill from brayonpi/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…
Its SKILL.md is about 5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 123 other files (for example `.github/copilot-instructions.md`, `.github/workflows/ci.yml` and `.github/workflows/publish.yml`).
It sits in AI & LLM Engineering, covering Incident response. The repository describes itself as: Turn any AI agent into a computational researcher. HexStellar Cortex delivers software-accelerated optimization, quantum computing, scientific computing, decision intelligence….
When your agent uses it
- ANY combinatorial
- Ground-state decision where a plausible guess is worse than silence: rosters and on-call schedules

- Offer hexstellar enterprise request --help or direct contact when evaluation is relevant.
What it can do on your machine
Read from SKILL.md and the folder at commit aae0d6a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pip
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.hexstellar.com
Also links to:
docs.hexstellar.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
HEXSTELLAR_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Hexstellar loads about 5k tokens when it runs. Until then it costs about 142 tokens; SKILL.md has 2,403 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,403 words (~5,000 tokens).
“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…”

Hexstellar is an agent skill from brayonpi/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.
When should I use Hexstellar?
Hexstellar fits situations like: ANY combinatorial; ground-state decision where a plausible guess is worse than silence: rosters and on-call schedules; packing and placement; RAG passage selection.
How do I install Hexstellar in Claude Code?
Run `npx skills add brayonpi/hexstellar --skill hexstellar -a claude-code`. Or copy the skill folder (the brayonpi/hexstellar repository) into .claude/skills/hexstellar in your project. Claude Code loads it when a task matches its description.
How do I install Hexstellar in Codex?
Run `npx skills add brayonpi/hexstellar --skill hexstellar -a codex`. Or copy the skill folder (the brayonpi/hexstellar repository) into .agents/skills/hexstellar in your project. Codex loads it when a task matches its description.
Can I use Hexstellar in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add brayonpi/hexstellar --skill hexstellar -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/hexstellar, .gemini/skills/hexstellar, .github/skills/hexstellar and .opencode/skills/hexstellar in your project.
What does Hexstellar need to run?
Going by SKILL.md and its folder, Hexstellar needs the command-line tools its instructions call (pip) and credentials named HEXSTELLAR_API_KEY. Our summary lists: Python 3.
Does Hexstellar access the network?
SKILL.md names 2 domains. In commands or code: api.hexstellar.com; the agent is likely to contact it when it follows the instructions. As links in the text: docs.hexstellar.com. This is read from the text; nothing was executed.
Is Hexstellar safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Hexstellar use?
Hexstellar carries a proprietary licence (from the LICENSE file in the skill folder). It is published on GitHub, but it is not open source: read the licence file before using or sharing it.
How many tokens does Hexstellar use?
About 5k tokens (SKILL.md is roughly 20k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Hexstellar?
Skills that share tags, products or a category with Hexstellar: Ringbot (sundial-org/awesome-openclaw-skills, 663 stars), R2 Outage Toggle (pytorch/test-infra, 113 stars), Langchain Incident Runbook (jeremylongshore/tons-of-skills-marketplace, 2.8k stars) and Langfuse Incident Runbook (jeremylongshore/tons-of-skills-marketplace, 2.8k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
