What
A block of embedded skill content no longer ships with the CLI: the Cowork plugin authoring guide with its packaging steps, the component-schema and example-plugin references, the MCP discovery reference covering registry search and connector suggestions, the JavaScript and Python chart-palette validators, and the data-visualisation anti-patterns document.
Details
The marker strings from that content appear eight times in v2.1.245 and not at all in v2.1.246.
Evidence
Normal-vision floor
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
