Candidate rows lead with domain icons instead of localized text prefixes; pointer and keyboard share one reducer-owned highlight (last input wins); drillable folder rows reveal a localized Browse-folder + Tab keycap hint with the library chevron; pending sources render skeleton bars; the menu spans the composer card. The editable @dir/ text decorates color-only — the domain icon now belongs exclusively to the settled reference chip. Composer placeholders advertise / and @, and the zh copy for commands is unified to 指令.

Summary
This package powers the input trigger pipeline of the Web GUI: it detects / and @ typed under the caret, shows a grouped candidate menu, and routes a pick to the registered source. Sources register through ctx.inputTriggers — the / command source (ui-commands), the @ file and session reference sources (ui-reference), and any business package — and the conversation wiring drives the pipeline per session. Typing a trigger seeds every source registered for it; a chrome launcher can also open exactly one source over the current selection. The pipeline is presentation-only: picks produce command claims or reference inserts whose consequences belong to the consuming host and input packages.

Use this package
Mount this plugin alongside ui-conversation; the menu then appears in the input overlay when the user types a trigger under the caret. Grouped candidates render under title rows; a pick routes to the source, and the consuming surface applies the result — a slash command opens its popup or executes, a reference inserts its inline token.
Keyboard and mouse
The composer surface keeps focus while the menu is open: rows pick on mousedown, the highlight rides aria-activedescendant, and a pointer press outside both the menu and the composer card dismisses it. Space and Enter adjudication polls the optional matchSpace/matchEnter hooks in registration order; the first non-undefined answer wins, and a source can refuse a submission it cannot consume whole. A candidate declaring drill: true carries a second verb beside the settling pick: its trailing chevron and the Tab key route the same row through onPick with action: 'drill' (every other path reports 'pick'), and Tab passes untouched on rows without the flag so native focus traversal survives.
Understand the implementation
Implementation internals — click to expand
src/core/ is the pure core — trigger detection, menu reduction, and exact match, with zero React/DOM/cordis — while src/client/service.ts wires the core to the menu snapshot store, the per-hit candidate fetch (generation-gated, AbortSignal-superseded, failed sources dropping silently with a console record), and the pick paths. One InputTriggerController resolves per session scope (sessionOf); the conversation wiring layer drives track/arbitrate/onSpace/adjudicate on the controller. A source is warmed into every session controller it can reach; sources whose lexicon rolls change after warm implement subscribeLexicon and the controller re-polls on each notification. MenuView self-registers into conversation.input.overlay (list kind, session scope) and renders null while closed. The overlay SlotMap merge lives here because the dependency direction (ui-conversation → ui-input-trigger) admits no reverse type import.
Further Exploration
Read these pages when the trigger pipeline is not enough. They move from the pipeline to the sources that register into it and the shell that owns the input.
- ui-commands — registers the
/command source into this pipeline and owns the command popup shell. - ui-reference — registers the
@file and session reference sources. - ui-conversation — declares the input overlay slot and owns the composer and input machine.
- Web client architecture — how browser plugin rows load and register slots.
Model Experience
None, as the trigger pipeline is browser presentation only — picks produce command claims and reference inserts whose model-visible consequences are owned by the consuming host and input-machine packages.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
These limits define the current trigger pipeline. They are current package constraints, not a general menu comparison or a task backlog.
- Global source layer only — session-scope source registration (per-session shadowing) is designed but not enabled; the ledger tracks the trigger condition, a real per-session source need.
InputTriggerCandidate.iconrenders as text —MenuViewdrops the string into the icon slot verbatim; wiring to the design-system icon enum lands when that enum ships.- Overlay SlotMap merge home is split from slot ownership — the sole
conversation.input.overlaymerge lives here, while ui-conversation owns its anchor, children declaration, and lifecycle because the dependency direction is ui-conversation → ui-input-trigger.
