Plugins
scholar-search
Find academic papers, explore citations, and export BibTeX. Uses four tools under the hood:
- s2cli (Semantic Scholar) — paper recommendations, citation/reference networks, arXiv/DOI lookups
- openalexcli (OpenAlex) — broadest coverage (260M+ works), institution/journal queries, aggregation
- arxivy (arXiv) — direct arXiv search, paper lookup by ID, browse recent submissions by category
- dblpcli (DBLP) — high-quality, curated BibTeX export
All tools run via uvx — no installation needed.
paper-siphon
Convert academic PDFs to clean Markdown. Supports local files and remote URLs (e.g. arXiv). Three extraction modes:
- Default — fast Docling-based extraction, handles most papers
- VLM (
--vlm) — vision-language model for complex layouts and scans
- Formula enrichment (
--enrich-formula) — better LaTeX fidelity for math-heavy papers
Runs via uvx — no installation needed.

codex review --base main — review current branch against maincodex review --uncommitted — review work-in-progress changescodex exec '<prompt>' — custom prompted review, plan critique, or codebase exploration
claude-exec
Delegate code review, plan review, and deep exploration tasks to Claude Code CLI from Codex or other agents. The mirror of codex-exec — lets non-Claude agents get an independent second opinion. Key commands:
