YeonGyu-Kim 6e301c8bb3 fix(runtime): prevent orphaned tool-result at compaction boundary; /cost JSON
Two fixes:

1. compact.rs: When the compaction boundary falls at the start of a
   tool-result turn, the preceding assistant turn with ToolUse would be
   removed — leaving an orphaned role:tool message with no preceding
   assistant tool_calls. OpenAI-compat backends reject this with 400.

   Fix: after computing raw_keep_from, walk the boundary back until the
   first preserved message is not a ToolResult (or its preceding assistant
   has been included). Regression test added:
   compaction_does_not_split_tool_use_tool_result_pair.

   Source: gaebal-gajae multi-turn tool-call 400 repro 2026-04-09.

2. /cost resume: add JSON output:
   {kind:cost, input_tokens, output_tokens, cache_creation_input_tokens,
    cache_read_input_tokens, total_tokens}

159 CLI + 431 runtime tests pass. Fmt clean.

Claw Code

Claw Code is the public Rust implementation of the claw CLI agent harness. The canonical implementation lives in rust/, and the current source of truth for this repository is ultraworkers/claw-code.

Important

Start with USAGE.md for build, auth, CLI, session, and parity-harness workflows. Make claw doctor your first health check after building, use rust/README.md for crate-level details, read PARITY.md for the current Rust-port checkpoint, and see docs/container.md for the container-first workflow.

Current repository shape

  • rust/ — canonical Rust workspace and the claw CLI binary
  • USAGE.md — task-oriented usage guide for the current product surface
  • PARITY.md — Rust-port parity status and migration notes
  • ROADMAP.md — active roadmap and cleanup backlog
  • PHILOSOPHY.md — project intent and system-design framing
  • src/ + tests/ — companion Python/reference workspace and audit helpers; not the primary runtime surface

Quick start

Note

cargo install clawcode will not work — this package is not published on crates.io. Build from source as shown below.

# 1. Clone and build
git clone https://github.com/ultraworkers/claw-code
cd claw-code/rust
cargo build --workspace

# 2. Set your API key (Anthropic API key — not a Claude subscription)
export ANTHROPIC_API_KEY="sk-ant-..."

# 3. Verify everything is wired correctly
./target/debug/claw doctor

# 4. Run a prompt
./target/debug/claw prompt "say hello"

Note

Windows (PowerShell): the binary is claw.exe, not claw. Use .\target\debug\claw.exe or run cargo run -- prompt "say hello" to skip the path lookup.

Note

Auth: claw requires an API key (ANTHROPIC_API_KEY, OPENAI_API_KEY, etc.) — Claude subscription login is not a supported auth path.

Run the workspace test suite:

cd rust
cargo test --workspace

Ecosystem

Claw Code is built in the open alongside the broader UltraWorkers toolchain:
