This adds a prompt-mode permission flow for the Rust CLI, surfaces permission policy details in the REPL, and improves tool output rendering with concise human-readable summaries before the raw JSON payload. The goal is to make tool execution feel safer and more legible without changing the underlying runtime loop or adding a heavyweight UI layer. Constraint: Keep the permission UX terminal-native and incremental Constraint: Preserve existing allow and read-only behavior while adding prompt mode Rejected: Build a full-screen interactive approval UI now | unnecessary complexity for this parity slice Confidence: high Scope-risk: narrow Reversibility: clean Directive: Keep raw tool JSON available even when adding richer summaries so debugging fidelity remains intact Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q Not-tested: Manual prompt-mode approvals against live API-driven tool calls
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/.
