speckit.wireframe.view

Open the interactive viewer for all wireframes in this project. Side-navigation auto-discovered from specs/*/wireframes/*.svg, with keyboard shortcuts, zoom, focus mode, and status badges derived from .issues.md files.

User Input

$ARGUMENTS

Accepts:

• --port N — override default port 3000
• --no-open — start the server but don't auto-open the browser
• --rebuild-manifest — regenerate the wireframes-manifest.json before launching
• No args — sensible defaults

Workflow

Step 1: Verify prerequisites

The viewer needs Python 3.9+ for the manifest generator + static server. Check:

python3 --version

If Python 3.9+ is missing, print this and stop:

═══════════════════════════════════════════
VIEWER REQUIRES PYTHON 3.9+
═══════════════════════════════════════════
The wireframe viewer uses Python's built-in http.server
for a zero-dependency static server.

Install Python 3.9+ and re-run this command.

Alternative: open
  .specify/extensions/wireframe/viewer/viewer.html
directly in a browser. (Some features like manifest
auto-discovery will not work without a server.)
═══════════════════════════════════════════

Step 2: Generate/refresh the manifest

Always regenerate unless --rebuild-manifest is explicitly disabled — the cost is sub-second and manifests drift when wireframes get added or reviewed.

python3 .specify/extensions/wireframe/scripts/generate-manifest.py \
  --specs-dir specs \
  --output .specify/extensions/wireframe/viewer/wireframes-manifest.json

Output shows feature + wireframe count:

Wrote manifest: .specify/extensions/wireframe/viewer/wireframes-manifest.json
  Features: 3
  Wireframes: 7

Step 3: Write project config

Build .specify/extensions/wireframe/viewer/viewer-config.json from what the project exposes. Two facts get captured:

Project name — current directory basename (e.g. ~/repos/my-app → "my-app"):

PROJECT_NAME=$(basename "$PWD")

Project repo URL — derive from origin remote if this is a git repo. Normalize SSH-form remotes to HTTPS so browsers can open them:

PROJECT_REPO=""
if REMOTE=$(git remote get-url origin 2>/dev/null); then
  case "$REMOTE" in
    git@github.com:*)       PROJECT_REPO="https://github.com/${REMOTE#git@github.com:}" ;;
    git@*:*)                PROJECT_REPO="$REMOTE" ;;  # leave non-GitHub SSH alone
    http*|https*)           PROJECT_REPO="$REMOTE" ;;
  esac
  # Strip trailing .git
  PROJECT_REPO="${PROJECT_REPO%.git}"
fi

Write the JSON:

{
  "project_name": "<PROJECT_NAME>",
  "project_repo": "<PROJECT_REPO>"
}

If there's no git repo (or no origin remote), project_repo stays empty — the viewer degrades gracefully and the Project footer link becomes a no-op # until the user configures one.

Step 4: Launch the server

Serve from the project root (not the viewer directory) so absolute paths like /specs/<feature>/wireframes/<svg> resolve without Python's http.server blocking .. traversal:

python3 -m http.server 3000 --bind 127.0.0.1

The viewer is then reachable at /.specify/extensions/wireframe/viewer/viewer.html and the SVGs at /specs/....

Report:

═══════════════════════════════════════════
VIEWER RUNNING
═══════════════════════════════════════════
URL:     http://localhost:3000/.specify/extensions/wireframe/viewer/viewer.html
Manifest: 3 features, 7 wireframes

Keyboard shortcuts:
  ← →      Previous / next wireframe
  1-9      Jump to feature N
  F        Toggle focus mode
  L        Toggle legend
  +/-      Zoom
  ?        Show all shortcuts

Stop the server with Ctrl+C.
═══════════════════════════════════════════

If --no-open was not passed, attempt to open the browser:

URL="http://localhost:3000/.specify/extensions/wireframe/viewer/viewer.html"

# Linux
xdg-open "$URL" 2>/dev/null

# macOS
open "$URL" 2>/dev/null

# Windows / WSL
start "$URL" 2>/dev/null

Fall back to printing the URL if auto-open fails.

What the viewer shows

• Left sidebar: auto-generated nav grouped by feature, with status badges:
  • 📝 draft (no .issues.md yet)
  • 🚧 review (.issues.md present, status PATCH or REGENERATE)
  • ✅ approved (.issues.md present, status PASS — signed off in spec.md)
• Center: the SVG at configurable zoom
• Footer: project link, extension link, portfolio link, coffee link
• Focus mode (F): hides nav and footer for full-canvas review
• Legend drawer (L): shows callout color legend and badge keys

Manifest refresh

The manifest is generated fresh each /speckit.wireframe.view invocation. If wireframes change while the viewer is running, re-run this command to refresh, or refresh the browser after running:

python3 .specify/extensions/wireframe/scripts/generate-manifest.py

DO NOT

• Bind to 0.0.0.0 without explicit user consent — localhost-only by default for security
• Keep the server running in the background after the command exits — leave it foreground so Ctrl+C works cleanly
