The + button and a typed / open one menu with an Add section (File, Goal,
Plan, Feedback) and a Commands section (Compact, Permission, Model, Export)
in usage order; rows carry a glyph, a localized title and description, and
the command name as an alias where the localized title differs. Built-in
Host rows get their face from the ui-commands dictionaries when the catalog
description is the canonical English text. A menu pick fills the locale's
claim token (/计划 ) while the submission executes the catalog name, and a
typed localized token resolves on Space and Enter in every locale. The File
row is a new action contribution kind that opens the composer's file picker
through the scoped slash/input-pick-files event; the paperclip button is
removed and the + button reads "Add files or run commands".
textContent/data-placeholder probes replace inputValue/placeholder reads,
evaluate-string selectors move to the composer anchor, queued fills wait
out the submit round-trip's read-only span, and the refreshed aria goldens
drop the hover tooltip the old interaction order happened to capture.
The client-bundle preset pins the production/development exports condition
(lexical's node-condition file selects its flavor with a top-level await a
CJS bundle cannot carry); the composer carries an explicit aria-label (a
div's data-placeholder does not name it the way a textarea placeholder
did); READMEs, the composer.bar slot doc, and the Agent Note record the
editor architecture; web e2e drives the contenteditable surface.
