Hybridizer Port

hybridizer claude-plugin

A Claude Code plugin that helps migrate existing C# codebases to CUDA using Hybridizer.

The plugin bundles:

• A hybridizer-port skill — Hybridizer attributes, device-code restrictions, the build pipeline, host launch idioms, kernel patterns (reductions, cooperative blocks, warp shuffle, CUB), CUDA graph capture, perf tuning, and a curated gotchas list.
• Three subagents — hybridizer-porter (analyse a C# function and propose a kernel shape), hybridizer-reviewer (check a diff against the gotchas list), hybridizer-builder (locate the Hybridizer CLI via PATH / local tool manifest / user prompt, read --display-license-details for licensed flavors, invoke the transcoder, and parse errors).
• Slash commands — /hybridizer-init, /hybridizer-port, /hybridizer-review, /hybridizer-profile, /hybridizer-log.
• An opt-in hook that appends every porting prompt to porting-to-hybridizer.md in your project (off by default; toggle with /hybridizer-log on).

The skill is wired with progressive disclosure: SKILL.md is short and indexes deeper reference files in hybridizer-port/skills/hybridizer-port/references/ that Claude pulls in only when a task touches that topic.

Requirements

• Claude Code (any recent version with plugin / marketplace support).
• Python 3 in PATH — used only by the optional porting-log hook (/hybridizer-log on). The rest of the plugin works without it.
• Hybridizer install if you're actually porting code (the plugin's content references it; the plugin itself is install-light).

Install

From this marketplace (recommended)

/plugin marketplace add hybridizer-io/claude-plugin
/plugin install hybridizer-port@hybridizer

From a local clone (for development)

git clone https://github.com/hybridizer-io/claude-plugin /path/to/claude-plugin
/plugin marketplace add /path/to/claude-plugin
/plugin install hybridizer-port@hybridizer

Usage

The skill auto-loads when Claude detects you're working on Hybridizer code (CUDA porting context, references to [Kernel]/[EntryPoint], Hybridizer transcoder build issues, etc.). You can also invoke it explicitly with the slash commands above.

To enable the optional porting log:

/hybridizer-log on

This creates a .hybridizer-log-enabled flag in the current project; every prompt thereafter is appended to porting-to-hybridizer.md. Disable with /hybridizer-log off.

Status

Early — content is distilled from a working port (TinyLlama Q8_0 inference, ~125 tok/s on RTX 5070). Expect iteration. Issues and PRs welcome.
