FAQ
What is hexum_expand?
When one folded function, class, or method is the thing to patch, expand that name only.
When should the agent call hexum_expand?
When one folded function, class, or method is the thing to patch.
Does Hexum replace Cursor or Claude Code?
No. You keep Cursor, Claude Code, Antigravity, Codex, or Grok. Hexum is not an editor and not a model. You paste a key into the agent you already use.
Does the architecture check use an AI?
No. It reads a rules file in your repo and reports forbidden imports. It does not call a model, so it does not guess.
Does Hexum store my repo?
No. We do not keep the code your agent sends. We do not train on it. Policy: /zdr.
