Read the full paper,
not just the abstract.
An abstract tells you a paper exists; the full text tells you whether it says what you think. PubMed Central holds the open-access article body, and pmc_fulltext fetches it by PMCID so an agent reads the methods and results, not a summary of them.
What the instrument does
PubMed Central (PMC) is the NIH free full-text archive of biomedical literature. Where a paper is open access, PMC has the complete article — introduction, methods, figures legends, results and references.
On the console, pmc_fulltext takes a PMCID and returns the article body. It is the second half of a PubMed hit: search finds the paper, PMC reads it.

How Perslis integrates PubMed Central
The handoff is automatic. When pubmed_search returns a record that carries a PMCID, that identifier is the key straight into full text — no second search, no guessing a URL. The claim and the paragraph it came from stay one click apart.
This is what makes grounded reading possible offline too: full text pulled through PMC can be harvested into a local topic pack, so a review still has the source article when the cable is pulled.
Ask
One question at the console — no per-service query language, no tab-hopping.
Route
Lois calls this instrument alongside the others and gathers what returns.
Pin
Every field keeps its source: database, accession, URL. A result that cannot name its source is refused by construction.
Admit
The PEEL gate decides what enters the lab record. Reported values stay verbatim; unsupported claims stay out.
A real, source-pinned result
Pulled live from the service and pinned to its identifier — the same contract every answer on the console is held to.

Why route PubMed Central through one console
Abstract to article, in one step
A PMCID from a PubMed hit resolves straight to full text — the console closes the loop for you.
Grounded reading for agents
An LLM reasons over the real methods and results, not a truncated abstract or a paraphrase.
Survives the cable being pulled
Open-access full text can be harvested into a local pack so the source paper stays with the record offline.
Instruments PubMed Central talks to
Full text is the destination of a literature search. PMC sits downstream of the indexes that find the paper.
