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.
The dedicated "Bash" agent type (described as "Command execution specialist for running bash commands") has been removed from the built-in agent list. This simplifies the agent architecture.
Evidence
Removed bash agent definition (search for "Command execution specialist")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
