💎 Richard: Interactive AI Console (french-pronounced, like Claude but more Riccardiano)

Feature Request

Richard (pronounced "Ri-shar" à la française 🇫🇷) is the interactive REPL console for the Antigravity Ruby SDK.

Like Claude Code's claude CLI, but Rubyish and Riccardiano.

Features

• 🤔 Thinking tokens rendered in gray italic (collapsed by default)
• 💬 Response streamed in bold cyan
• 💾 Tool calls shown inline in yellow
• /think or Ctrl-O to toggle thinking expansion
• Multi-turn piped input: (echo q1 ; echo q2) | just rv-console
• Readline with history and tab completion

Usage

just rv-console              # interactive
just rv-console-workspace .  # with workspace
(echo "ciao" ; echo "quanti primi sotto 1000?") | just rv-console

Status

• Phase 1: Thinking in Chunks (v0.6.0)
• Phase 2: Console REPL
• Phase 3: Tests (258 passing)
• Ctrl-O keybinding (currently /think only)
• Named tool rendering (Read, RunCommand vs harness_tool)
• Multi-turn piped input e2e test

Start by running just rv-console and reviewing the existing REPL behavior and the 258 passing tests. Focus on the unchecked items: Ctrl-O expansion, named tool rendering, and the multi-turn piped-input end-to-end test. Done means the requested console interactions work without regressing the completed phases.
