Claw Code

Claw Code is a local coding-agent CLI implemented in safe Rust. It is Claude Code inspired and developed as a clean-room implementation: it aims for a strong local agent experience, but it is not a direct port or copy of Claude Code.

The Rust workspace is the current main product surface. The claw binary provides interactive sessions, one-shot prompts, workspace-aware tools, local agent workflows, and plugin-capable operation from a single workspace.

Current status

• Version: 0.1.0
• Release stage: initial public release, source-build distribution
• Primary implementation: Rust workspace in this repository
• Platform focus: macOS and Linux developer workstations

Install, build, and run

Prerequisites

• Rust stable toolchain
• Cargo
• Provider credentials for the model you want to use

Authentication

Anthropic-compatible models:

export ANTHROPIC_API_KEY="..."
# Optional when using a compatible endpoint
export ANTHROPIC_BASE_URL="https://api.anthropic.com"

Grok models:

export XAI_API_KEY="..."
# Optional when using a compatible endpoint
export XAI_BASE_URL="https://api.x.ai"

OAuth login is also available:

cargo run --bin claw -- login

Install locally

cargo install --path crates/claw-cli --locked

Build from source

cargo build --release -p claw-cli

Run

From the workspace:

cargo run --bin claw -- --help
cargo run --bin claw --
cargo run --bin claw -- prompt "summarize this workspace"
cargo run --bin claw -- --model sonnet "review the latest changes"

From the release build:

./target/release/claw
./target/release/claw prompt "explain crates/runtime"

Supported capabilities

• Interactive REPL and one-shot prompt execution
• Saved-session inspection and resume flows
• Built-in workspace tools for shell, file read/write/edit, search, web fetch/search, todos, and notebook updates
• Slash commands for status, compaction, config inspection, diff, export, session management, and version reporting
• Local agent and skill discovery with claw agents and claw skills
• Plugin discovery and management through the CLI and slash-command surfaces
• OAuth login/logout plus model/provider selection from the command line
• Workspace-aware instruction/config loading (CLAW.md, config files, permissions, plugin settings)

Current limitations

• Public distribution is source-build only today; this workspace is not set up for crates.io publishing
• GitHub CI verifies cargo check, cargo test, and release builds, but automated release packaging is not yet present
• Current CI targets Ubuntu and macOS; Windows release readiness is still to be established
• Some live-provider integration coverage is opt-in because it requires external credentials and network access
• The command surface may continue to evolve during the 0.x series

Implementation

The Rust workspace is the active product implementation. It currently includes these crates:

• claw-cli — user-facing binary
• api — provider clients and streaming
• runtime — sessions, config, permissions, prompts, and runtime loop
• tools — built-in tool implementations
• commands — slash-command registry and handlers
• plugins — plugin discovery, registry, and lifecycle support
• lsp — language-server protocol support types and process helpers
• server and compat-harness — supporting services and compatibility tooling

Roadmap

• Publish packaged release artifacts for public installs
• Add a repeatable release workflow and longer-lived changelog discipline
• Expand platform verification beyond the current CI matrix
• Add more task-focused examples and operator documentation
• Continue tightening feature coverage and UX polish across the Rust implementation

Release notes

• Draft 0.1.0 release notes: docs/releases/0.1.0.md
