A market place of claude code skills and MCP servers useful for HPC development using agentic tools.
In Claude Code:
/plugin marketplace add RIKEN-RCCS/HPC-Agentic-SDK
/plugin install RAPTOR
This installs all plugins needed for HPC code tuning workflows.
Codex can install plugins from this repository through the plugin marketplace:
codex plugin marketplace add RIKEN-RCCS/HPC-Agentic-SDKThen open /plugins in Codex and install the plugins you need.
| Plugin | Description |
|---|---|
| RAPTOR | Profile and alter floating-point precision in C, C++, and Fortran using RAPTOR |
| Tadashi | Check whether loop transformations are mathematically safe using polyhedral analysis |
| make-vibe | Expose Makefile targets as MCP tools for building and running code on local or remote HPC systems |
| OpenACC | Automatically insert OpenACC directives into Fortran code using a verified template library for reliable GPU parallelization |
Full cluster agents for job submission, monitoring, and filesystem operations via the IRI Facility API. Install one if you work on the corresponding machine.
| Plugin | Machine | Description |
|---|---|---|
| hokusai | HOKUSAI BigWaterfall2 (HBW2, x86_64) | Submit and monitor Slurm jobs, manage files, search the HBW2 User's Guide |
| rikyu | AI4S (NVIDIA GB200, aarch64) | Submit and monitor Slurm jobs, manage files, search the AI4S documentation |
| rccs-cloud | R-CCS Cloud (~20 partitions: A64FX, x86_64, NVIDIA/AMD/Intel GPUs) | Submit and monitor Slurm jobs, manage files, search the built-in documentation |
/plugin install hokusai
/plugin install rikyu

claude_fairy runs Claude Code headlessly on a schedule — waking at 1am, working through your PLAN.md, and writing a report by morning. The plugins above are its toolbox for HPC work.
# Install the plugins first
/plugin marketplace add RIKEN-RCCS/HPC-Agentic-SDK
/plugin install make-vibe
/plugin install rccs-cloud
# Then initialize and start the fairy in your project
uvx --from claude-fairy cfairy init
uvx --from claude-fairy cfairy daemonEdit PLAN.md with your tasks. The fairy will use the installed plugins each night to build, run, and optimize on the cluster.
