What it does
Reika is installed with npm, pnpm or Homebrew. Point it at a model server and run reika in a project. Old tool output collapses to short summaries. Requests stay append-only. Reika says this lets a slow local engine's prompt cache survive. Reika detects repeated reads and runaway reasoning and stops them. Blind edits go back for a read first. TypeScript edits are typechecked. Plan progress is tracked from what actually happened. Reika has modes for planning before anything changes, putting a harder change through a test-and-review procedure, keeping a small window lean, or chatting. Shift+Tab switches modes. Reika says it does not make a small model smarter, but makes working with one less frustrating.
