Yeachan-Heo cb24430c56 Make tool approvals and summaries easier to understand
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-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.
