Yeachan-Heo 3faf8dd365 feat: make rusty-claude-cli usable end-to-end
Wire the CLI to the Anthropic client, runtime conversation loop, and MVP in-tree tool executor so prompt mode and the default REPL both execute real turns instead of scaffold-only commands.

Constraint: Proxy auth uses ANTHROPIC_AUTH_TOKEN as the primary x-api-key source and may stream extra usage fields
Constraint: Must preserve existing scaffold commands while enabling real prompt and REPL flows
Rejected: Keep prompt mode on the old scaffold path | does not satisfy end-to-end CLI requirement
Rejected: Depend solely on raw SSE message_stop from proxy | proxy/event differences required tolerant parsing plus fallback handling
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep prompt mode tool-free unless the one-shot path is explicitly expanded and reverified against the proxy
Tested: cargo test -p api; cargo test -p tools; cargo test -p runtime; cargo test -p rusty-claude-cli; cargo build; cargo run -p rusty-claude-cli -- prompt "say hello"; printf '/quit\n' | cargo run -p rusty-claude-cli --
Not-tested: Full interactive tool_use roundtrip against the proxy in REPL mode

Rust port foundation

This directory contains the first compatibility-first Rust foundation for a drop-in Claude Code CLI replacement.

Current milestone

This initial milestone focuses on harness-first scaffolding, not full feature parity:

  • a Cargo workspace aligned to major upstream seams
  • a placeholder CLI crate (rusty-claude-cli)
  • runtime, command, and tool registry skeleton crates
  • a compat-harness crate that reads the upstream TypeScript sources in ../src/
  • tests that prove upstream manifests/bootstrap hints can be extracted from the leaked TypeScript codebase

How to use

From this directory:

cargo fmt --all
cargo check --workspace
cargo test --workspace
cargo run -p rusty-claude-cli -- --help
cargo run -p rusty-claude-cli -- dump-manifests
cargo run -p rusty-claude-cli -- bootstrap-plan

Design notes

The shape follows the PRD's harness-first recommendation:

  1. Extract observable upstream command/tool/bootstrap facts first.
  2. Keep Rust module boundaries recognizable.
  3. Grow runtime compatibility behind proof artifacts.
  4. Document explicit gaps instead of implying drop-in parity too early.

Relationship to the root README

The repository root README explains the leaked TypeScript codebase. This document tracks the Rust replacement effort that lives in rust/.
