… docs - Add npm caching to reduce install time by ~2 minutes - Create library-docs-generate.yml workflow to pre-build docs every 6 hours - Add skip_library_docs input to build action - Configure preview builds to use pre-built library docs instead of regenerating - Conditionally skip Python/terraform-docs setup when using pre-built docs - Production builds still generate fresh docs for accuracy Preview builds now complete in 4-7 minutes instead of 15-23 minutes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

- Add workflow_call trigger to library-docs-generate.yml - Production workflow now calls library-docs-generate first - Production uses freshly built library docs from the release - Both preview and production now use the same tarball approach 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

When 'rebuild-library-docs' label is present on a PR, the preview build will regenerate library docs before building (like production). Default behavior uses pre-built docs from the latest release. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

what
generate-library.ymlworkflow builds library docs weekly (Monday 8am UTC)rebuild-library-docslabel to force library doc regeneration on PR previewsExpected Results
How it works
Library Docs Generation (
generate-library.yml)The workflow generates docs in parallel across 3 jobs:
After all jobs complete, a Package and Release job:
library-docs.tar.gzlibrary-docs-latestThis workflow runs:
scripts/docs-collator/**changesrebuild-library-docslabel is presentBuild Action (simplified)
The build action (
build-website) now only:.build-harnesslibrary-docs-latestreleasemake build-productionThe build will fail if no
library-docs-latestrelease exists. The library docs workflow must run at least once to bootstrap.Preview Builds (on PR)
Optional: Add the
rebuild-library-docslabel to force fresh library doc generation.Production Builds
generate-library.ymlto regenerate fresh library docs (parallel jobs)Changes Summary

why
Preview builds were taking 35-40 minutes due to sequential library documentation generation. Since library content (components, modules, GitHub Actions docs) rarely changes during PR reviews, using pre-built docs is acceptable for preview environments while production always gets fresh docs.
