FAQ
What is hexum_skill?
Hosted Hexum cannot see the agent’s disk. The agent looks for the skill file; if it is missing, it calls this tool and writes what comes back.
When should the agent call hexum_skill?
First Hexum use this session if SKILL.md is missing, or when intensity changes.
Does Hexum replace Cursor or Claude Code?
No. Hexum is a hosted MCP server. You keep Cursor, Claude Code, Antigravity, Codex, or Grok. Hexum is not an IDE and not a model.
Is hexum_check an LLM?
No. hexum_check is deterministic. It maps files to layers in architecture.hexum and reports forbidden imports. It does not call a model.
Does Hexum store my repo?
No. Zero Data Retention is on Usage and Teams. MCP payloads are not stored. Hexum does not train on your code. Policy: /zdr.
