DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
Plugin agent names no longer repeat the plugin prefix twice.

What
If a plugin agent's file already names itself with its plugin prefix, that prefix is now stripped before the agent type is assembled, so the plugin name is not repeated twice in the resulting agent name.
Details
Plugin skill loading now builds the path to the skill file through a single shared path-join helper.
Evidence
Plugin agent file
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
