Skill Instructions

Purpose

Provide a repeatable workflow to generate HTML exports and screenshots for the website using real repository artifacts.

Hard Rules

Must

  • Use src/tools/Oocx.TfPlan2Md.HtmlRenderer to generate HTML from markdown reports.
  • Use src/tools/Oocx.TfPlan2Md.ScreenshotGenerator (Playwright) to generate screenshots from those HTML exports.
  • Store website screenshots under website/src/assets/screenshots/.
  • Update the consuming website source when screenshot assets change (for example the relevant page in website/src/pages/ or shared content data in website/src/_data/).

Must Not

  • Do not hand-edit screenshots or create “mock” screenshots that aren’t generated from real HTML exports.

Golden Example

# Preferred Method: Use the automated script
scripts/generate-screenshot.sh \
  --plan examples/firewall-with-static-analysis/plan.json \
  --output-prefix firewall-example \
  --selector "details:has(summary:has-text('azurerm_firewall_network_rule_collection'))" \
  --thumbnail-width 580 --thumbnail-height 400 \
  --lightbox-width 1200 --lightbox-height 900 \
  --render-target azdo \
  --open-details-selector "details"

# This generates 12 screenshot variants automatically:
# - Thumbnail and lightbox crops
# - Light and dark themes
# - 1x and 2x DPI versions
# - Azure DevOps rendering style

# Manual Method (for advanced use cases):
# 1) Generate HTML (Azure DevOps flavor, wrapped)
dotnet run --project src/tools/Oocx.TfPlan2Md.HtmlRenderer -- \
  --input artifacts/comprehensive-demo.md \
  --flavor azdo \
  --template src/tools/Oocx.TfPlan2Md.HtmlRenderer/templates/azdo-wrapper.html \
  --output artifacts/comprehensive-demo.azdo.html

# 2) Capture a screenshot with details expanded
DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 dotnet run --project src/tools/Oocx.TfPlan2Md.ScreenshotGenerator -- \
  --input artifacts/comprehensive-demo.azdo.html \
  --output website/src/assets/screenshots/full-report-azdo.png \
  --open-details "details" \
  --full-page

Actions

  1. Pick the markdown report under artifacts/ to use as the source.
  2. Generate the required HTML exports with src/tools/Oocx.TfPlan2Md.HtmlRenderer.
  3. Generate screenshots from the exported HTML with src/tools/Oocx.TfPlan2Md.ScreenshotGenerator.
  4. Place the generated screenshots in website/src/assets/screenshots/.
  5. Update the consuming page or content source so it references the new screenshot asset.
  6. Verify the relevant page in website/dist/ uses the correct light or dark asset variants and that any lightbox or screenshot wrapper still works.
