# `claude_storage` CLI Documentation

### Scope

- **Purpose**: Document the clg command-line interface for Claude Code conversation storage exploration.
- **Responsibility**: Reference documentation for commands, parameters, types, workflows, and test planning.
- **In Scope**: commands, params, types, parameter groups, dictionary, workflows, format/, user_story/.
- **Out of Scope**: CLI tool design (→ `feature/001_cli_tool.md`), quality constraints (→ `invariant/`).

Reference documentation for the `claude_storage` CLI binary — a tool for exploring Claude Code conversation storage. All commands are read-only except `.session.ensure`, which creates the session working directory on disk.
