PRIMA Scholar

These notes cover every PRIMA Scholar release up to 2.2.1, newest first. Each entry describes what changes for you. The notes leave out changes that only affect how GenAI Skills Academy builds and maintains the product.

2.2.1

Released on 14 October 2026, this version fixes the installer and corrects tool descriptions and documentation. No search or library tool changes how it behaves.

• Marketplace install. You can now add PRIMA Scholar as a Claude Code plugin with /plugin marketplace add larrygmaguire-hash/prima-scholar and install it with /plugin install prima-scholar@prima-scholar. It then stays installed between sessions, as Installing in Claude Code explains.
• Reinstalling keeps your API keys. Re-running install.sh used to delete PUBMED_API_KEY, SEMANTIC_SCHOLAR_KEY, CORE_API_KEY and any other setting from the server entries. It now keeps every existing setting and adds only missing defaults. It also leaves a correct entry alone and copes with a quote mark in a workspace path.
• Plugin settings with nothing exported. On the plugin route, a setting you had not exported reached the servers as literal placeholder text, and the library could create a database file with a placeholder name. Every setting now has a default, and an empty library path uses ~/.research-library/library.db.
• OpenAlex contact email. An empty OPENALEX_MAILTO now falls back to CROSSREF_MAILTO, as an unset one already did.
• /library actions match the tools. Browsing a collection, filtering by tag and the statistics step now call the right library tools.
• Accurate tool descriptions. The descriptions of scholar_citations, scholar_full_text, scholar_get_paper and scholar_search now match what each tool does. See Tools Reference.
• Accurate import documentation. The library skill now lists what each importer extracts from a file.
• All ten databases named. /scholar and the researching-topics skill now list all ten databases.
• Correct version numbers. The library server now reports the release version.
• Documentation. The README now orders the install routes, lists all three agents, adds uninstall steps and states the requirements for the installer.

2.2.0

Released on 30 September 2026, this version changes the plugin’s commands, skills and agents and leaves both servers as they were.

• Per-group settings for the literature watch. Any topic group can now set its own sort order, result count and venues. See Literature Watch.
• Papers without abstracts. The watch now tries one title search to find a missing abstract. If none turns up, the new missing_abstract setting decides what happens, and the default sets the paper aside in an “Abstract Unavailable” section of the digest.
• New default digest folder. The default digest_dir is now Documentation/Reports/Literature Watch, a folder that exists in every AI Business OS layout.
• Troubleshooting help. The literature watch skill gains rows for CrossRef results that bunch on the last day of the window and for venue filters that find almost nothing.

2.1.0

Released on 2 September 2026.

• Literature watch. A new /literature-watch command, skill and agent scan your standing topics for papers published since the last run, screen them, write a dated digest with APA7 references and import the selected papers to your library.
• Date windows. scholar_search gains published_after and published_before, which take a year, a month or a full date.
• Sort orders. scholar_search gains sort_by, with open access first, citations, newest first or relevance.
• Venue and DOI filters. scholar_search gains venues to keep only named journals or publishers, and exclude_dois to skip papers you already have.
• Publication dates on every result. Each paper now carries its publication date as precisely as the source gives it.
• Future placeholder dates kept out. When you sort by date, results with placeholder dates in the future no longer lead the list.
• CrossRef year filters. CrossRef searches now respect year_from and year_to and return citation counts.

2.0.3

Released on 10 April 2026.

• The README now lists every product in the suite, and the plugin reports its correct version.

2.0.2

Released on 2 April 2026.

• Nested clone check. install.sh now stops when you have cloned PRIMA Scholar inside the workspace you are installing into, and tells you how to move it.
• Updates replace skills and agents. Re-running the installer now updates the skills and agents it ships.
• Git ignores the server copies. The installer adds the server folders to your workspace’s .gitignore.
• Fix guide for nested clones. fix-nested-repo.md walks Claude through repairing a workspace where the clone already sits inside it.

2.0.1

Released on 29 March 2026.

• Library starts on a new database. The library server no longer crashes when it creates a fresh database.
• install.sh. A new installer copies the commands, skills, agents and servers into a workspace and registers the servers.

2.0.0

Released on 27 March 2026, this version adds six databases and replaces the per-database tools with five combined ones.

• Ten databases. OpenAlex, CORE, Europe PMC, ERIC, bioRxiv and medRxiv, and DBLP join PubMed, arXiv, Semantic Scholar and CrossRef. See Data Sources.
• Search wizard. scholar_wizard reads your query, detects your discipline and suggests the best databases before you search.
• Open access first. Every result shows whether it is open access, open access papers come first, and open_access_only hides the rest.
• Full text. scholar_full_text retrieves open access text or a download link.
• Year filters. scholar_search gains year_from and year_to.
• One lookup and one citation tool. scholar_get_paper accepts several kinds of identifier, and scholar_citations follows citations forwards and backwards.
• Missing keys handled gently. A source that needs a key you have not set is skipped with a message.
• Five tools replace eleven. The per-database search and lookup tools are gone. If you had prompts or instructions that named them, change them to the five new tools.

1.2.0

Released on 23 March 2026.

• The library database now records its version and updates itself.

1.1.0

Released on 22 March 2026.

• More citation styles. Search tools now return citations in APA7, Harvard, Chicago, Vancouver, IEEE and MLA, chosen with citation_style. See Citing Sources in APA7.

1.0.0

Released on 22 March 2026, the first release searched PubMed, arXiv, Semantic Scholar and CrossRef. It also provided a local document library with full-text search, collections and tags, APA7 citations, a research agent, and the /scholar, /cite and /library commands.
