Yeachan-Heo 0346b7dd3a Tighten tool parity for agent handoffs and notebook edits
Normalize Agent subagent aliases to Claude Code style built-in names, expose richer handoff metadata, teach ToolSearch to match canonical tool aliases, and polish NotebookEdit so delete does not require source and insert without a target appends cleanly. These are small parity-oriented behavior fixes confined to the tools crate.\n\nConstraint: Must not touch unrelated dirty api files in this worktree\nConstraint: Keep the change limited to rust/crates/tools\nRejected: Rework Agent into a real scheduler | outside this slice and not a small parity polish\nRejected: Add broad new tool surface area | request calls for small real parity improvements only\nConfidence: high\nScope-risk: narrow\nReversibility: clean\nDirective: Keep Agent built-in type normalization aligned with upstream naming aliases before expanding execution semantics\nTested: cargo test -p tools\nNot-tested: integration against a real upstream Claude Code runtime

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/.
