Audit + harden + optimize live Cloudflare zones/domains — read-only sweep of each zone (SSL/TLS mode, HSTS, min TLS, TLS 1.3, Always-Use-HTTPS, Brotli, HTTP/3, 0-RTT, Early Hints, caching, security level, Bot Fight Mode, WAF, DNS proxy/TTL + SPF/DKIM/DMARC hygiene, DNSSEC) → ok/attention/action report grouped by category → per-category confirm → apply via Cloudflare MCP. Use when the user says "harden my cloudflare", "optimize my cloudflare zones", "audit my domains", "check my cloudflare settings", "secure my dns", "harden my dns", "hide my origin IP", "set up HSTS/DNSSEC", "am I leaking my origin", "is my cloudflare config optimal", or "tune cloudflare". For BUILDING on Cloudflare (Workers/Pages/KV/D1/Terraform) use the cloudflare skill instead.
Audit and harden the 4 pivoshenko brand sites on Vercel (pivoshenko.dev, pivoshenko.startpage, pivoshenko.wallpapers, pivoshenko.ai), team `pivoshenko`. Read-only sweep → per-site report (ok/attention/action) → confirmed fixes. Emphasizes security headers and analytics coverage. Use when the user says "audit vercel", "check vercel hygiene", "harden the sites", "vercel security", "check analytics coverage", "vercel health check", or wants a periodic once-over of the Vercel setup. Delegates perf/cost → `vercel-optimize`, CLI ops → `vercel-cli`, deployments → `deploy-to-vercel`.
Maintenance sweep of the Obsidian vault — orphan notes, missing/invalid frontmatter, dead wikilinks, stale project statuses, INDEX.md drift, unprocessed inbox. Use when the user says "lint my wiki", "vault health check", "clean up my vault", "is my wiki up to date", or on a periodic review.
Create or update project pages in the Obsidian vault's 03 PROJECTS — status changes, decision log entries, milestones, meeting notes, future-project ideas. Use when the user says "log a decision for <project>", "update <project> status", "new project page", "what's the state of <project>", "we had a meeting about <project>", "add a project idea", or finishes a chunk of project work worth recording in the wiki.
Deep-clean macOS — user/system junk (caches, logs, trash, iOS backups), leftovers from deleted apps, dev-tool junk (brew, docker, Xcode, npm/pnpm/uv/cargo caches, stale node_modules), disk-space breakdown + login-items audit. Use when the user says "clean my mac", "free up disk space", "disk is full", "what's eating my storage", "remove app leftovers", "my mac is slow", or any macOS storage/cleanup complaint. Health checks, updates, tune-up ("optimize/maintain my mac") → macos-maintenance instead. Always scans read-only first, reports sizes, deletes only after explicit per-category confirmation.
Periodic macOS maintenance + optimization — read-only health sweep (pending OS/brew updates, disk health + SMART, memory pressure + swap, battery condition, Time Machine recency, Spotlight indexing state, crash/panic reports, uptime, login-item load) → ok/attention/action report → confirmed fixes. Use when the user says "maintain my mac", "mac health check", "tune up my mac", "optimize my mac", "run maintenance", "is my mac healthy", "update everything", or wants a periodic once-over. Also covers targeted fixes when a check or the user flags an issue — Spotlight reindex, Launch Services rebuild, DNS/font cache flush, frozen Finder/Dock, runaway process triage. Storage/junk/leftovers/disk-space → macos-cleanup instead.
Write and edit blog posts for pivoshenko.dev — interrogate for raw material, outline as a dependency graph, confirm sections, draft section-by-section, run anti-slop edit passes, ship as MDX. Use when the user says "write a blog post", "draft a post about X", "edit/revise/improve this article", "tighten this draft", "turn this into a post", "publish to my blog", or shares notes/an experience meant for pivoshenko.dev. The goal is bespoke practitioner writing, not generic AI prose.
Obsidian Flavored Markdown syntax reference — wikilinks, embeds, callouts, properties/frontmatter, tags, comments, block IDs. Use when creating or editing .md files in an Obsidian vault, or when the user mentions wikilinks, callouts, frontmatter, embeds, or Obsidian notes. The wiki-* skills assume this syntax.
