+> Hidden expert. Quiet executor.
+>
+> Hermit is an MCP executor for Claude Code and Codex. Your main agent handles planning, review, and conversation; Hermit quietly handles edits, test runs, refactors, commits, and other mechanical execution on a cheaper local or flat-rate model.
 
-> Hermit adds a dedicated MCP execution lane under Claude Code or Codex: keep the premium orchestrator for judgment, and route the repetitive repo work to predictable local or flat-rate models.
