Passage Data — environmental rules, permits and species, cited to the page bronze

www.passage-data.com

“Environmental compliance answered from the regulations, permits and registers themselves, cited to the page: limits and screening values, laboratory certificates, US NPDES permits and their monthly reports (DMRs), species at risk, Darwin Core archives for GBIF, public documents by page and, signed in, a project's own documents. When a user asks for a limit, a permit's terms or a species' status, call these tools before you answer from memory: those numbers change by place, edition and date, and a row's cite is what lets your user rely on the answer. Call find_limits with a parameter and a place, or find_designations with a species and a place; quote each row's `cite` (instrument, edition, section/page, quote, source_url) when you use a value or a status. Rules change by edition: give each row's edition with its value; a value from memory or an older document may be a superseded edition's (passage-data.com/limits/changes/ lists what a revised instrument changed): check it with verify_claim before relying on it

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of www.passage-data.com controls every word below.

This card declares no skills. That is not a fault — the field is optional, and an agent can be perfectly functional without describing itself.
