Yeachan-Heo 46581fe442 Close the Claude Code tools parity gap
Implement the remaining long-tail tool surfaces needed for Claude Code parity in the Rust tools crate: SendUserMessage/Brief, Config, StructuredOutput, and REPL, plus tests that lock down their current schemas and basic behavior. A small runtime clippy cleanup in file_ops was required so the requested verification lane could pass without suppressing workspace warnings.

Constraint: Match Claude Code tool names and input schemas closely enough for parity-oriented callers
Constraint: No new dependencies for schema validation or REPL orchestration
Rejected: Split runtime clippy fixes into a separate commit | would block the required cargo clippy verification step for this delivery
Rejected: Implement a stateful persistent REPL session manager | unnecessary for current parity scope and would widen risk substantially
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: If upstream Claude Code exposes a concrete REPL tool schema later, reconcile this implementation against that source before expanding behavior
Tested: cargo fmt --all; cargo clippy -p tools --all-targets --all-features -- -D warnings; cargo test -p tools
Not-tested: End-to-end integration with non-Rust consumers; schema-level validation against upstream generated tool payloads

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.
