ChatMentionPopover limits display to 5 agents (slice(0,5)) with scroll container
// @vitest-environment jsdom pragma added to component tests for JSX dynamic import support

Phase 22 Plan 04: Slash Command and @Mention Popovers Summary

Slash command routing table (5 commands, /search disabled) and agent @mention autocomplete popover — both standalone, wired into ChatInput in plan 05.

Performance

Accomplishments

  • Created slash-commands.ts with SLASH_COMMANDS (5 entries) and resolveAgentFromContent routing function that prioritizes slash commands over @mentions over active agent fallback
  • Created ChatSlashCommandPopover — 260px popover opening upward with command list; /search greyed with "Coming soon" per UI spec
  • Created ChatMentionPopover — 200px popover opening upward showing agent icon + name + role label, filtered by query, max 5 agents, loading skeleton, empty state

Task Commits

Files Created/Modified

  • ui/src/components/ChatSlashCommandPopover.tsx — 260px slash command popover with cmdk Command component
  • ui/src/components/ChatSlashCommandPopover.test.tsx — routing logic tests (5 pass) + export smoke test
  • ui/src/components/ChatMentionPopover.tsx — 200px agent mention autocomplete with icon/name/role rows
  • ui/src/components/ChatMentionPopover.test.tsx — export smoke test + 4 todo items for future wiring tests
  • ui/src/lib/agent-role-colors.ts — dependency copy for worktree build (exists in phase-22 branch from plan 22-00)

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Added jsdom pragma to component tests

  • Found during: Task 1 test verification
  • Issue: Dynamic import() of JSX component failed with react/jsx-dev-runtime error in node test environment
  • Fix: Added // @vitest-environment jsdom pragma to both test files, matching existing pattern in ChatAgentSelector.test.tsx
  • Files modified: ChatSlashCommandPopover.test.tsx, ChatMentionPopover.test.tsx
  • Commit: 99d01d9e

2. [Rule 3 - Blocking] Added agent-role-colors.ts to worktree

  • Found during: Task 2 implementation
  • Issue: Worktree branch lacks phase-22-00 foundation files; ChatMentionPopover imports agent-role-colors which didn't exist in worktree
  • Fix: Created agent-role-colors.ts with identical content to phase-22 branch version
  • Files modified: ui/src/lib/agent-role-colors.ts (new file, already exists on phase-22 branch)
  • Commit: a3bb02c5
  • Note: When cherry-picked to gsd/phase-22-agent-streaming, this will be a no-op (file already exists with same content)

Known Stubs

  • ChatMentionPopover.test.tsx: 4 it.todo() items for render/interaction tests — per plan spec, wiring tests deferred until ChatInput integration in plan 22-05
  • ChatSlashCommandPopover.test.tsx component test section: export smoke test only — render/interaction tests deferred per plan spec

Self-Check: PASSED
