Opt-in (showUltracodeAgents, default OFF) panel that visualizes ultracode /
Workflow-tool runs like Claude Code's "working agents" TUI: LEFT = runs + phases
(selectable tasks), RIGHT = each run's agents with model, live state, tokens
burned, and tool calls.
Standalone — ZERO edits to subagent-watcher.ts. A new workflow-run-watcher.ts
singleton globs the run-state tree (~/.claude/projects/*/*/workflows/wf_*.json,
disjoint from the transcript tree), strips the heavy script/scriptPath/result/logs
fields (174KB -> ~25KB/run), and emits workflow:run_* SSE events. The LEFT list
ships lightweight summaries (getLightState replay + SSE); the RIGHT pane fetches
the full run (with agents[]) via GET /api/workflows/:runId on selection.
Backend: workflow-run-watcher.ts, types/workflow-run.ts, config/workflow-config.ts,
3 SSE events, getLightState workflowRuns replay, GET /api/workflows[/:runId],
showUltracodeAgents schema key + boot-gate (default OFF) + live toggleService.
Frontend: ultracode-panel.js (debounced master-detail render, run/phase select),
header launcher (btn-ultracode-agents--hidden marker -> mobile-guard-exempt),
App Settings toggle (SYNCED, deliberately not in displayKeys).
Agent states on disk are start|progress|done (start=queued; done has
durationMs/resultPreview). Tests: workflow-run-watcher (9), workflow-routes (3).
Verified: tsc/lint/prettier/frontend-syntax/public-assets/mobile-header-guard
clean; full test:ci green (2986 passed); live server + Playwright e2e against 25
real runs (28-agent grid, phase filter, OFF hides launcher).
Design: docs/ultracode-agent-viz-plan.md (rev. 3).
