Verify changes to the claude-for-msft-365-install admin scripts and commands by driving them against an isolated fake $HOME.

Keep heavy imports off the django.setup() path that every process (web, celery, temporal, migrate, shell, CI) pays for. Use when touching AppConfig.ready(), wiring signal receivers, editing the lazy API router (posthog/api/rest_router.py or its __init__.py shim), deferring a heavy import, when the startup-import-budget guard fails, or when merging master into a long-lived branch that made the router lazy.

Use this skill to add a new TTS engine to Voicebox. It walks through dependency research, backend implementation, frontend wiring, PyInstaller bundling, and frozen-build testing. Always start with Phase 0 (dependency audit) before writing any code.

Manage GitHub Issues 2.0 relationships with gh CLI: parent issues, sub-issues, blocked-by, and blocking links.

Use when applies to key landing pages, blog posts, product pages, and any page targeting competitive queries. Use when diagnosing poor rankings or after a Google Helpful Content update.

Use when applies to sites that use both robots.txt disallow rules and meta robots noindex tags. Use when investigating why deindexed pages still appear in search results.

Use when reviewing image assets, markup, and CDN or build transforms related to Optimise images for faster loading. Check encoded size, rendered size, loading strategy, and above-the-fold impact together.

Use when reviewing image assets, markup, and CDN or build transforms related to Lazy load offscreen images. Check encoded size, rendered size, loading strategy, and above-the-fold impact together. Missing `loading='lazy'` is only a valid finding when you can reasonably tell the image is offscreen or non-critical.

Use when reviewing rendered HTML, interactive components, or design-system patterns related to Make modal dialogs keyboard accessible. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

Use when reviewing image assets, icon libraries, or components that render illustrations to identify culture-specific content that may need locale overrides or replacement with neutral alternatives.

Use when generating URL slugs from article titles, auditing URL structures for unnecessary depth or length, or reviewing URL patterns in a CMS or router configuration.

Use when auditing content pages for over-optimisation, reviewing AI-generated content that may repeat target phrases excessively, or checking meta tags and alt text for unnatural keyword accumulation.

Use when auditing page weight for crawl efficiency, investigating why certain page content is not appearing in Google's index, or reviewing server-rendered pages that embed large JSON payloads in HTML.

Use when auditing slow page loads, heavy assets, or rendering delays related to Optimize Google Tag Manager implementation. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.

Use when auditing content pages for freshness signals, setting up HTTP Last-Modified headers in a web server config, or ensuring Article JSON-LD dateModified is updated when CMS content changes.

Use when auditing content pages for citation quality, suggesting authoritative sources to link for factual claims, or reviewing whether a page's external link attributes (nofollow, noopener) are correctly set.

Use when auditing a blog, news site, or YMYL content site for trust signals, drafting editorial policy page content, or evaluating whether a site meets Google's quality rater trustworthiness criteria.

Use when reviewing large SPA bundles, new dependency additions, or routes that feel slow to hydrate. Focus on code that is not required for the initial view and can move behind route transitions, user interaction, or viewport-based loading.

Spotify Now Playing-style card with album art, progress bar, and playback controls, suited to video overlays or personal homepages.

Follow-up design polish skill inspired by Impeccable. Use after a web or HTML artifact exists to audit, critique, polish, animate, harden, and prepare the page for a live/share pass.
