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 can queue a prompt into the conversation

Plugins Notable

Plugins can drop a prompt into your conversation, labelled as theirs and rate-limited.

What

$.prompt.submit lets a plugin put a prompt into the running conversation, tagged as coming from that plugin rather than from you. Text starting with / is refused so a plugin cannot fire a slash command in your name, and attachments are refused. Each plugin has a per-session submission count and a minimum gap between its prompts.

Details
  • Requires an interactive session attached to the process. Headless -p runs and the SDK reject the call.
  • The submitted prompt is marked with the plugin's name as its origin.
Evidence

$.prompt.submit submits a prompt to the model; a text beginning with / would run a command as the user

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