Codex Paper Search for arXiv and Crossref Citation Checks
Search public literature indexes and keep a DOI or arXiv identifier for each candidate. Inspect partial errors before drawing conclusions from a search with missing results.
中文Install in Codex
Codex, Paper Search CLI, uv, and Python 3.10 or newer. The example uses public arXiv and Crossref searches.
- Copy `plugins/paper-search-tools/skills/paper-search-usage/` from the pinned checkout to `.agents/skills/paper-search-usage/`. Keep that commit's sibling `skills/setup/SKILL.md` as the setup guide.
- Install the CLI as documented in the pinned setup file, confirm available sources with `paper-search sources`, then open the project in Codex.
Example task
Ask `$paper-search-usage` for public papers on ‘image segmentation evaluation’, with up to three hits each from arXiv and Crossref. Keep a DOI or arXiv ID for each result.What to check
Expect up to six literature candidates with their source index recorded. Report a provider error separately from a completed search with no matches.
