Workflow Visualizer

March 17, 2026 · View on GitHub

Introduced in v2.19.0

The workflow visualizer is a full-screen TUI overlay that shows project progress, dependencies, cost metrics, and execution timeline in an interactive four-tab view.

Opening the Visualizer

/gsd visualize

Or configure automatic display after milestone completion:

auto_visualize: true

Tabs

Switch tabs with Tab, 1-4, or arrow keys.

1. Progress

A tree view of milestones, slices, and tasks with completion status:

M001: User Management                        3/6 tasks ⏳
  ✅ S01: Auth module                         3/3 tasks
    ✅ T01: Core types
    ✅ T02: JWT middleware
    ✅ T03: Login flow
  ⏳ S02: User dashboard                      1/2 tasks
    ✅ T01: Layout component
    ⬜ T02: Profile page
  ⬜ S03: Admin panel                         0/1 tasks

Shows checkmarks for completed items, spinners for in-progress, and empty boxes for pending. Task counts and completion percentages are displayed at each level.

Discussion status is also shown when milestones have been through a discussion phase — indicates whether requirements were captured and what state the discussion left off in.

2. Dependencies

An ASCII dependency graph showing slice relationships:

S01 ──→ S02 ──→ S04
  └───→ S03 ──↗

Visualizes the depends: field from the roadmap, making it easy to see which slices are blocked and which can proceed.

3. Metrics

Bar charts showing cost and token usage breakdowns:

By phase — research, planning, execution, completion, reassessment
By slice — cost per slice with running totals
By model — which models consumed the most budget

Uses data from .gsd/metrics.json.

4. Timeline

Chronological execution history showing:

Unit type and ID
Start/end timestamps
Duration
Model used
Token counts

Ordered by execution time, showing the full history of auto-mode dispatches.

Controls

Key	Action
`Tab`	Next tab
`Shift+Tab`	Previous tab
`1`-`4`	Jump to tab
`↑`/`↓`	Scroll within tab
`Escape` / `q`	Close visualizer

Auto-Refresh

The visualizer refreshes data from disk every 2 seconds, so it stays current if opened alongside a running auto-mode session.

Configuration

auto_visualize: true    # show visualizer after milestone completion
