get_review — Pith's review of one specific paper, in one call: the verdict, confidence, novelty and correctness scores, one-line summary, weakest assumptsearch_papers — Search Pith-reviewed papers by title and abstract. Call this when the user names a research topic, phenomenon, method, or paper title withoulatest_reviews — The papers Pith reviewed most recently, newest first. Call this when the user asks what is new, notable, or recently reviewed in a field or analyze_paper_claims — The structured argument of one specific paper: what it actually asserts, the premises it assumes, the machinery connecting those premises toget_claims — Alias of analyze_paper_claims: the same ledger of what the paper asserts, its premises, machinery, and falsifier, in argument order.search_claims — Full-text search over every scientific claim Pith has extracted, across all reviewed papers. Call this when the user asks who claims somethiget_paper_falsifier — The falsifier for one specific paper's core claim: the concrete observation, experiment, or computation that would settle or disprove it, plget_falsifier — Alias of get_paper_falsifier: the same falsifier and watcher count.get_signed_reviews — Published human signed reviews of one paper: reviewer identity, axis deltas against the machine review, claim verdicts, defects, predictionsget_reviewer_record — A reviewer's published signed reviews and, when present, their calibration record (Brier score, open predictions, positivity skew). Call thiget_record — The compiled record of one paper: the authors' own sentences, arranged with typed labels. It carries the main claim in the authors' words, eresolve_paper — Turn a pasted arXiv id, arXiv URL, DOI, or Pith Number into the arXiv id the other tools key on. ``resolved`` is false when the input did nopaper_packet — One paper's compiled record, small enough to hold beside others: the main claim and contribution in the authors' words, each abstract sentencitation_neighbors — One hop from a paper: every reference entry with its resolved work identity, the papers that cite it, and, where a record exists, the citingpaper_bridge — Whether either paper cites the other, the resolved works both cite (on or off arXiv), and the papers that cite both.paper_connections — What other arXiv papers do with this paper, and what it does with the arXiv papers it cites: builds on, uses the method or tool, uses the dacheck_claim — Which arXiv papers support a scientific statement, which contradict it, and which study it without deciding, each with the paper's own main verify_citation — Whether the cited paper's own sentences support what a sentence attributes to it: supports, partly supports (a condition is missing), contrafind_passages — Author sentences the classifier labeled with one role, across every stored record, each with its probability and paper. Abstract-tier recordrecord_coverage — Sources read and levels run for one paper's record, or the number of stored records by tier. Call before treating an empty result as a findimy_citations — For the papers claimed on the account behind your key: how many papers cite each, whether they cite it as support, extension or disagreementmy_reviews — Pith's machine review verdict and the count of published signed human reviews for each paper claimed on the account behind your key. Needs acheck_my_draft — Resolve each reference in a draft, flag retracted works, and for arXiv papers show how later papers cite them: as support, and whether any cask_field — Read the papers closest to a question and return, for each, whether its own abstract sentences answer yes, no or not addressed, with the decNot tested by KitScout yet. When our harness runs it, pros, cons and the tasks we tried appear here, with the date and evidence.
