CvLAC (MinCiencias) tools 13
loginAuthenticate in CvLAC and persist the browser session.read_cvlacRead current CvLAC sections, including articles, books, chapters, theses, juries and five kinds of technical production. Returns existing items for comparison; list results include every JMesa page.read_cvlac_detailRead the full record page of one CvLAC item. The list views only show a couple of columns, so this is the only way to see the fields a write actually stored (role, dates, institution, financing). Finds the row by label, case- and accent-insensitive.read_portfolioRead and parse the configured portfolio site (PORTFOLIO_URL), merged with the curated proyectos/software/eventos from data/portfolio-extra.json.diffCompare CvLAC vs portfolio. Returns four buckets: missing, toUpdate, similar (close to an existing entry — a human decides) and upToDate.update_sectionApply a single change to a CvLAC section. Takes a screenshot for confirmation. An "add" whose item resembles an existing entry returns status "needs_confirmation" and writes nothing; resolve it with action:"update" or repeat with confirm_duplicate:true. A "delete" also writes nothing until it is repeated with confirm_delete:true. A picker whose search matched several rows — a common university name can match close to 200 institutions in CvLAC — also returns needs_confirmation, with the candidates in "choices"; repeat with the chosen id in data.institucionId. For articles provide title, year and issn/revista; for books provide title, isbn, year, editorial and area; for chapters provide title, bookTitle, year and area; for theses provide title, tipo, year, institution and programme; for juries provide title, nivel, year, orientado, institution and programme; technical sections require title and year, with section-specific fields. Catalogue choices are answered by repeating the call with revistaId, libroId, editorialId, programaId, areaId or institucionId in data. Coauthors, keywords, recognitions and linked thesis students are completed from the CvLAC website. For books, certificateCLCDO and certificateCLRI accept local PDF paths (maximum 2 MiB each).lookup_doiRead-only: look up a DOI in Crossref and return an article draft. Review it, then pass it to update_section with section:"articulos"; this tool does not write to CvLAC.complete_productComplete the post-save CvLAC phase for an existing product. It manages ordered keywords, knowledge areas, coauthors and recognitions; for theses it also links students with their participation. It reads current values, resolves catalogue names, and never removes an existing value without confirm_delete:true. Use dry_run:true to preview catalogue resolution and removals without writing.read_profileRead the two CvLAC pages that hold one record instead of a list: the researcher profile text (txt_desc_perfil), the table of academic social networks (Google Scholar, ORCID, LinkedIn, Scopus...) and the áreas de actuación. None of them appears in read_cvlac.update_profileWrite the researcher profile text and/or the academic social networks. Networks are MERGED over what CvLAC already stores — its form rewrites the whole table, so this reads it first and posts everything back. Pass url:null to remove one. A network CvLAC does not list goes in "otro" with its name in "label". Removing one needs confirm_delete:true. The profile text cannot be blanked: CvLAC marks it required. The areas list is replaced whole, so dropping one also needs confirm_delete:true.syncRun a full diff and apply the unambiguous items (missing + toUpdate). Items that resemble existing CvLAC entries are never written; they are listed for a human to resolve. It previews by default; pass dry_run:false to apply changes explicitly.screenshotCapture a CvLAC page for debugging: the given url, or else the last list, record or form page a tool visited, reloaded as it is now. Action links (delete, save) are refused, because in CvLAC opening one performs it.- +1 more on the listing page
HasData Google Scholar tools 3
hasdata_google_scholar_case_law_getScholarCaseLawOpinionGet Scholar Case Law Opinion Looks up a Google Scholar Case Law opinion by its `caseId` (as returned in a google/scholar organic result's `caseId`, when searching with `asSdt` set to a case-law court scope, or in another case-law result's `citedCases`). Returns the case title, party names, court, procedural history, argued/decided dates, short citations, docket numbers, and every case cited within the opinion (grouped by cited case with a ready-to-call `hasdataLink`). Use to build legal-research and case-law-analysis workflows, or to walk a citation graph one cited case at a time.hasdata_google_scholar_cite_getScholarCitationFormatsGet Scholar Citation Formats Looks up citation formats and export links for a single Google Scholar organic search result, identified by its `resultId` (as returned in a google/scholar organic result). Returns formatted citation snippets (MLA, APA, Chicago, Harvard, Vancouver) and reference-manager export links (BibTeX, EndNote, RefMan, RefWorks). Use to build citation/bibliography features or complete a research workflow started with google/scholar.hasdata_google_scholar_scholar_getScholarSearchResultsGet Scholar Search Results Scrapes Google Scholar for a query with author:/source: search helpers, year range (asYlo/asYhi), cited-by and all-versions lookups (cites/cluster), review-article and citation-inclusion filters, language/language-restrict, start/num pagination, and asSdt to scope to case law (asSdt=2006 for all courts, 2003 for Federal courts only, or 4/6/3 plus comma-separated court codes for specific courts) or toggle patents. Returns each organic result with title, link, snippet, publication info (authors with profile links), cited-by count and link, related-articles link, and all-versions count and link; a case-law result links to a scholar_case?case= page and carries a ready-to-call caseHasdataLink. Use for academic research, literature review automation, citation tracking, grounding research agents with scholarly sources, and walking case law straight into google/scholar-case-law.
