scion-c2rust

library1.0.0jsnpmunverified

Scion is an AI-powered migration toolkit for converting C/C++ codebases to idiomatic Rust, leveraging Claude Code or OpenCode as the underlying AI harness. Version 1.0.0 requires Node.js ≥18 and a Rust toolchain. It automates the full migration pipeline: source analysis, API mapping, task decomposition, implementation, and review. Key differentiators include support for multiple AI harnesses, a dashboard for progress monitoring at localhost:3456, and a self-healing continue command. Released as a community tool with active development as of 2026-04-06.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

Clone the Scion toolkit, run the installer to set up skills, commands, and agents, then start an interactive migration session with /scion:init.

git clone https://github.com/ZhifeiDou/Scion-HW.git cd /your/migration-project chmod +x /path/to/Scion-HW/install.sh /path/to/Scion-HW/install.sh claude /scion:init --source /path/to/c-project --target /path/to/rust-crate

Debug

Known issues

gotchaOpenCode v1 does not support PreToolUse/PostToolUse hooks, so hooks are skipped; manual refresh of dashboard may be needed.

fix

Use Claude Code for full hook support, or manually run 'node scripts/build-dashboard.js' to refresh the dashboard.

affects: >=1.0.0

breakingInstaller overwrites existing files in .claude/commands/ and .claude/agents/ without prompt on name collision.

fix

Backup your existing .claude directory before running install.sh.

affects: >=1.0.0

gotchaProject must be in a directory where you have already run 'claude init' or 'opencode init' before using /scion:init.

fix

Run the AI harness initialization command first: 'claude init' or 'opencode init'.

affects: >=1.0.0

deprecatedManual copying of files (old install method) is deprecated; always use the install.sh or install.ps1 scripts.

fix

Use the provided installer scripts instead of manual file placement.

affects: >=1.0.0

Errors

Error: Missing source argument. Usage: /scion:init --source <path> --target <path>
