11 capabilities over ARD, A2A and MCP. The inventory is incomplete. The latest atlas observation recorded a change: indeterminate.
11 capabilities, 3 of them tools. 3 only read.◇
AI reading, beta. side-effects v1 on claude-haiku-5.5, calibrated on MCP (golden-3). Only readings above a measured precision count. Counts are tools, not calls: no tool was called.
AI readings summary · beta
The service lists 3 tools, and 3 have AI readings.
define_term, list_glossary and search_glossary are read as read-only.
define_term: Returns a short definition and details of a gemology term, such as crown angle or fluorescence, including its grading report use.
list_glossary: Lists gemology glossary terms, optionally filtered by topic, each with a short definition and page reference.
Written by code from the AI readings on this page: it groups them and says nothing they do not.

Each class compares an observation with the previous atlas observation. Runs of unchanged observations are grouped. Struck values are what the previous observation recorded; inserted values are what this one recorded.
Declared and observed
3 tools declare hints; the AI readings agree with all 3 that have a reading.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.
