# Claw Code Parity (Rust Port)

> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

**claw-code-parity** is a temporary Rust port parity workspace for the [claw-code](https://github.com/instructkr/claw-code) project. It provides a faster, memory-safe harness runtime that mirrors the architectural patterns of Claude Code's agent harness — including tool wiring, command orchestration, and agent workflow management. This repo bridges the gap while the main `claw-code` repository completes its migration.

---

## What It Does

- Implements the core **agent harness runtime** in Rust for performance and memory safety
- Mirrors top-level subsystem names, command/tool inventories from the archived source
- Provides a **parity audit** mechanism to verify feature coverage against the original system
- Offers a CLI entrypoint for manifest output, subsystem listing, and parity summaries
- Designed to be orchestrated via AI coding agents (Claude Code, Codex, OmX, etc.)

---

## Installation & Setup

### Prerequisites

- Rust toolchain (stable, 1.75+): https://rustup.rs
- Cargo (bundled with Rust)

```bash
# Install Rust if needed
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env

# Clone the repository
git clone https://github.com/ultraworkers/claw-code-parity.git
cd claw-code-parity

# Build the project
cargo build

# Build in release mode for production use
cargo build --release

---

Key CLI Commands

The project exposes a CLI binary. Run via

cargo run --

or the compiled binary:

# Print parity summary
cargo run -- summary

# Print the current workspace manifest
cargo run -- manifest

# List subsystems (with optional limit)
cargo run -- subsystems --limit 16

# Run parity audit against local ignored archive (when present)
cargo run -- parity-audit

# Inspect mirrored command inventories
cargo run -- commands --limit 10

# Inspect mirrored tool inventories
cargo run -- tools --limit 10

After

cargo build --release

, use the binary directly:

./target/release/claw-code-parity summary
./target/release/claw-code-parity manifest
./target/release/claw-code-parity subsystems --limit 8
./target/release/claw-code-parity parity-audit

CLI Entrypoint Pattern

// src/main.rs

use clap::{Parser, Subcommand};

#[derive(Parser, Debug)]
#[command(name = "claw-code-parity", version, about = "Claw Code Rust Port Parity Tool")]
struct Cli {
    #[command(subcommand)]
    command: Commands,
}

#[derive(Subcommand, Debug)]
enum Commands {
    /// Render the parity summary
    Summary,
    /// Print the workspace manifest
    Manifest,
    /// List subsystems
    Subsystems {
        #[arg(long, default_value = "16")]
        limit: usize,
    },
    /// Run parity audit
    ParityAudit,
    /// List ported commands
    Commands {
        #[arg(long, default_value = "10")]
        limit: usize,
    },
    /// List ported tools
    Tools {
        #[arg(long, default_value = "10")]
        limit: usize,
    },
}

fn main() {
    let cli = Cli::parse();
    match cli.command {
        Commands::Summary => query_engine::render_summary(),
        Commands::Manifest => port_manifest::print_manifest(),
        Commands::Subsystems { limit } => {
            let subsystems = models::all_subsystems();
            for s in subsystems.iter().take(limit) {
                println!("{}: {} [{:?}]", s.name, s.description, s.status);
            }
        }
        Commands::ParityAudit => parity_audit::run(),
        Commands::Commands { limit } => {
            for cmd in commands::command_registry().iter().take(limit) {
                println!(
                    "{} — {} [ported: {}]",
                    cmd.name, cmd.description, cmd.ported
                );
            }
        }
        Commands::Tools { limit } => {
            for tool in tools::tool_registry().iter().take(limit) {
                println!(
                    "{} — {} [ported: {}]",
                    tool.name, tool.description, tool.ported
                );
            }
        }
    }
}

Query Engine: Rendering a Parity Summary

// src/query_engine.rs

use crate::models::{all_subsystems, PortStatus};

pub fn render_summary() {
    let subsystems = all_subsystems();
    let total = subsystems.len();
    let complete = subsystems
        .iter()
        .filter(|s| matches!(s.status, PortStatus::Complete))
        .count();
    let in_progress = subsystems
        .iter()
        .filter(|s| matches!(s.status, PortStatus::InProgress))
        .count();

    println!("=== Claw Code Parity Summary ===");
    println!("Total subsystems : {}", total);
    println!("Complete         : {}", complete);
    println!("In Progress      : {}", in_progress);
    println!("Not Started      : {}", total - complete - in_progress);
    println!();
    println!("Subsystem Status:");
    for s in &subsystems {
        let status_str = match &s.status {
            PortStatus::Complete => "✅ Complete".to_string(),
            PortStatus::InProgress => "🔄 In Progress".to_string(),
            PortStatus::NotStarted => "⬜ Not Started".to_string(),
            PortStatus::Blocked(reason) => format!("🚫 Blocked: {}", reason),
        };
        println!("  {} — {}", s.name, status_str);
    }
}

Common Patterns

Adding a New Subsystem

// In src/models.rs, extend all_subsystems()
pub fn all_subsystems() -> Vec<Subsystem> {
    vec![
        Subsystem {
            name: "tool-wiring".to_string(),
            description: "Tool registration and dispatch layer".to_string(),
            modules: vec![
                Module {
                    name: "tool_registry".to_string(),
                    source_path: "src/tools.rs".to_string(),
                    ported: true,
                    backlog_items: vec![],
                },
            ],
            status: PortStatus::InProgress,
        },
        // Add new subsystem here:
        Subsystem {
            name: "context-manager".to_string(),
            description: "Runtime context and state management".to_string(),
            modules: vec![],
            status: PortStatus::NotStarted,
        },
    ]
}

Adding a New Tool

// src/tools.rs
pub fn tool_registry() -> Vec<ToolEntry> {
    vec![
        ToolEntry {
            name: "bash".to_string(),
            description: "Execute shell commands".to_string(),
            ported: true,
        },
        ToolEntry {
            name: "file-read".to_string(),
            description: "Read file contents".to_string(),
            ported: false,  // Mark as not yet ported
        },
        // Add new tool:
        ToolEntry {
            name: "web-search".to_string(),
            description: "Search the web for information".to_string(),
            ported: false,
        },
    ]
}

Serializing State to JSON

use serde_json;
use crate::models::all_subsystems;

fn export_manifest_json() -> anyhow::Result<String> {
    let subsystems = all_subsystems();
    let json = serde_json::to_string_pretty(&subsystems)?;
    Ok(json)
}

// Usage
fn main() {
    match export_manifest_json() {
        Ok(json) => println!("{}", json),
        Err(e) => eprintln!("Failed to serialize manifest: {}", e),
    }
}

---

Troubleshooting

Build fails with missing features

# Ensure your Rust toolchain is up to date
rustup update stable
rustup default stable

# Clean and rebuild
cargo clean
cargo build

parity-audit

reports nothing

The parity audit requires the local ignored archive to be present. Ensure the archive path is configured (via environment variable if applicable):

export CLAW_ARCHIVE_PATH=/path/to/local/archive
cargo run -- parity-audit

Subsystem list is empty

Check that

all_subsystems()

in

src/models.rs

returns a populated

Vec

. If extending the model, ensure the new entries are added before the closing

]

.

Clap argument errors

Ensure argument names in the CLI match the

#[arg(long = "...")]

annotations exactly. Long flags use

--limit

, not

-limit

.

# Correct
cargo run -- subsystems --limit 8

# Incorrect (will error)
cargo run -- subsystems -limit 8
