Source Intelligence

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.

Plugins installed by running a command refresh once per session

Plugins

Plugins built by running a command re-run once per session in the background.

What

A plugin whose source is a command to run, rather than a marketplace download, is now re-run once per session in the background so its output is picked up. The background marketplace updater deliberately skips these, and the auto-update notification splits them into their own group alongside updated and blocked plugins.

Details
  • Subject to the same managed-settings gate as the rest of plugin auto-updating.
  • No marketplace network refresh happens on this path.
Evidence

is installed by running a command, which the background marketplace update never runs; it is re-resolved separately once per session.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
