Claude Code Skills — QuantumBFS

A small marketplace of Claude Code plugins, each shipping one skill.

Install

In Claude Code, add this repo as a marketplace, then install whichever plugin(s) you want:

/plugin marketplace add QuantumBFS/claude-code-skills
/plugin install download-papers@quantum-bfs
/plugin install submit-slurm-job@quantum-bfs
/plugin install verify-references@quantum-bfs

The @quantum-bfs suffix matches the name field in .claude-plugin/marketplace.json.

To update later:

/plugin marketplace update quantum-bfs

Plugins

download-papers

Download an academic paper as a PDF given a URL, DOI, paper title, or arXiv ID. Resolves in order: open web (author homepage, repositories) → Sci-Hub mirrors → arXiv.

Triggers on phrases like "download paper", "get me the PDF", "fetch this DOI". No configuration required.

submit-slurm-job

Generate and submit sbatch scripts for GPU compute jobs on a Slurm cluster. Handles partition selection, explicit GPU model in --gres, full Python path, and log file management.

Required configuration — add to your project's CLAUDE.md:

## Slurm Configuration

- PYTHON_PATH: `/path/to/miniconda3/envs/myenv/bin/python3`
- PROJECT_DIR: `/home/your_user/private/homefile`   # scripts/logs must live here
- PARTITION: `home`                                 # compute partition

Invoke with /submit-slurm-job (or just describe the job — Claude will pick up the skill).

verify-references

Verify a BibTeX bibliography against CrossRef metadata. The skill:

1. Scans your .tex files to flag uncited entries.
2. Queries CrossRef for every entry with a DOI and writes a side-by-side .bib.
3. Compares the two and produces a Markdown report listing field-level discrepancies (title, author, journal, volume, pages, year), sorted by similarity.

Useful before submission to catch hallucinated or stale BibTeX. Invoke by asking to "verify references" / "check the bib file". Requires Python 3 and an internet connection (for the CrossRef API).

Helper scripts shipped alongside a SKILL.md are referenced from the skill instructions via ${CLAUDE_SKILL_DIR}, which Claude Code expands to the skill's install directory at invocation time.

Contributing

Add a new plugin by:

1. Create plugins/<your-plugin>/.claude-plugin/plugin.json (use one of the existing files as a template).
2. Add the skill at plugins/<your-plugin>/skills/<your-plugin>/SKILL.md with YAML frontmatter (name, description).
3. Append an entry to .claude-plugin/marketplace.json.

Keep skills well-scoped, parameterize any user-specific paths, and document required configuration in this README.
