Welcome to Tandem

Tandem is a local-first protocol and toolchain for human/agent project coordination. It uses Markdown files, explicit work agreements called accords, validation-focused review, and completed-work logs to keep project state understandable in a normal repository.

This docs tree is the canonical Markdown source for Tandem documentation. The site/ project renders these files for the web.

  • Concepts explains Tandem’s core vocabulary.
  • Protocol describes the .tandem/ file model.
  • CLI covers the tandem command.
  • TUI covers the terminal interface.
  • Extensions covers integration adapters.
  • Guides collects task-oriented workflows.

Tandem is in early v0 implementation. The CLI surface is implemented for the current known scope, and the Ratatui TUI is under active development. Documentation should stay small, source-oriented, and easy to update as implementation details settle.
