Reported on production 2026-05-05:
agent plugin tab Plugins
0 installed
+ Install Plugin
this part should be default compact
Pre-fix: SkillsTab always rendered the Plugins section as a full
rounded-xl panel with vertical chrome — even when zero plugins were
installed and the registry browser was closed. The empty state
gave a lot of vertical real estate for content that's just "0
installed + Install button".
Fix: when installed.length === 0 AND registry closed AND initial
load completed, collapse the section into a single inline pill
("Plugins · 0 installed · + Install Plugin"). The full panel
re-mounts when:
- installed.length > 0 (a plugin landed → expand to surface the list)
- showRegistry === true (user clicked + Install Plugin → registry opens)
- !installedLoaded (avoid flash; the loading shell shows instead
until the first /plugins fetch resolves)
Accessibility:
- Compact pill: aria-label="Plugins (none installed)" + button
aria-expanded="false" + aria-controls="plugins-section"
- Full panel: button aria-expanded={showRegistry} + same aria-controls
- Section gets id="plugins-section" so the aria-controls reference
resolves once the section mounts
External workspaces: this is a pure canvas-frontend layout change —
applies to ALL workspace runtimes (external, claude-code, hermes,
langchain, codex, third-party MCP). No server-side change needed.
Tests
-----
SkillsTab.compactEmpty.test.tsx (4 tests):
- Compact pill renders when installed=0, registry closed, loaded
- Full panel renders when installed > 0
- Click + Install Plugin from compact → expands to full panel
(verified via aria-controls target id appearing in the DOM)
- During initial load (installedLoaded=false), compact pill does
NOT render — avoids a compact→full flash as the load completes
Per memory feedback_oss_design_philosophy.md: the SkillsTab is the
only tab that needs compact-empty today, but the pattern is
extractable into a shared EmptyStateCompactWrapper if Schedules /
Memories / Approvals adopt the same affordance later. Don't generalise
until the third use case (per the same memory, "every refactor toward
OSS plugin shape" without premature abstraction).
Verified
- tsc --noEmit clean
- All 4 tests pass
