Clinical-trial ID (NCT or AMTC): NCT04611802

Why not just ask the model?

Ask a plain model "which papers describe NCT04611802?" and it invents plausible citations and PMIDs, because it has no real trial→paper map to read from.

  • Plain model: fabricates titles, PMIDs, and journals that "sound like" the trial's literature, and conflates papers that merely cite COVID-vaccine work with the ones that actually report this trial.
  • Amass: the trial record carries a first-class referencesBiomedCore edge — the Amass IDs of the publications that describe it. Each fetched paper returns its verbatim title, journal, publicationDate, citationCount, journalQualityJufo, and isRetracted, with a relevance note quoted straight from the returned abstract. Nothing is guessed.

Why a skill, not a prompt?

This is a multi-step orchestration, not a one-shot lookup: one get_amass_trialcore_record reads the trial's referencesBiomedCore array, then a get_amass_biomedcore_record by-id fan-out runs once per referenced paper to pull its trust metadata and abstract, then a templated roll-up sorts by citation count and emits the CSV. Packaging it as a skill means the rate-limit-batched fan-out — and the metadata-only recovery for trials whose landmark papers overflow the per-call token budget — ships once and triggers with a single line, instead of re-pasting a brittle procedure every time.

Honest scope

The describing-paper count is the trial's referencesBiomedCore length (7 for PREVENT-19), not an exhaustive literature search — broaden coverage by also searching BioMedCore for the trial's acronym and unioning the results. Citation counts and trust metadata are verbatim from Amass and can lag the source databases by hours. Every relevance note is grounded in the paper's own abstract; where the abstract is silent it reads "not in abstract", and no trial-outcome string is paraphrased from a field the MCP does not expose (it does not surface primaryOutcomeMeasures).
