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-harnesscrate 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:
- Extract observable upstream command/tool/bootstrap facts first.
- Keep Rust module boundaries recognizable.
- Grow runtime compatibility behind proof artifacts.
- 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/.
