Site Launch Checklist
Pre-launch audit and setup workflow for shipping a new website. Opinionated for Cloudflare DNS + Vercel hosting + PostHog + Legal context.
Interaction style (READ FIRST)
This skill is intentionally interactive. Use `ask_user_input_v0` aggressively instead of assuming. Ask one question at a time with 2-4 tappable options. The user will tap, not type.
Always ask these questions at the start of a run (one at a time, in this order):
1. Site type: doc-site | marketing/lead-gen | SaaS-app | training/paid-course | personal-portfolio 2. Migration: greenfield-new-domain | migration-need-301-redirects | replacing-existing-on-same-domain 3. Multilingual: single-locale | en | fr+en | other-multi 4. PostHog setup: hogpost.samber.dev | set-up-new-proxy | skip-PostHog 5. AI scraper policy: use-default-for-site-type | customize-per-bot | block-all 6. Browser tool available: claude-chrome-extension | playwright | neither-skip-browser-checks
Ask again at every decision point throughout the phases, including:
- Whether to install Sentry / BetterStack / Crisp (depends on site type, ask explicitly)
- www vs apex canonical preference (most sites: apex; ask anyway)
- Which AI bots to allow if user chose
customize-per-bot - CSP tightness level:
strict-default-src-none|balanced-allow-self|permissive-for-marketing - Whether to skip a phase entirely (e.g., skip Phase 3 if non-FR site)
Never proceed past a decision point without explicit user input. Verbose checklists without checkpoints are not the goal.
Never install any MCP server or skill without explicit user confirmation. Always ask via ask_user_input_v0 before running npx skills add, claude mcp add, or any equivalent install command — even when the skill selection workflow proposes a curated subset.
How to use this skill
1. Run the start-of-session questions above. 2. Walk the user through phases 1-10 in order. For each phase: a. List items, ask if any should be skipped. b. For each remaining item, run the verification command (see "Verification tools" below). c. Report pass/fail. On fail, ask the user if they want to fix now or queue for later. 3. End with a status report grouped by phase, with blockers, recommended fixes, and optional improvements clearly separated.
Companion skills
Six skill packs are useful for site launches. Never install full multi-skill packs. The actual subset to install is decided at invocation time based on the site type the user confirms.
Pack inventory
| Pack | What it covers | Typically useful for |
|---|---|---|
AgriciDaniel/claude-seo | SEO + GEO + schema + hreflang + sitemaps audits, parallel sub-agents | All site types |
addyosmani/web-quality-skills | Lighthouse, Core Web Vitals, accessibility, performance, best practices | All site types |
trailofbits/skills | Security audit (OWASP, headers, dependencies) | All site types |
aaron-he-zhu/seo-geo-claude-skills | 20 SEO+GEO skills, CORE-EEAT + CITE frameworks, /seo: slash commands | Content-heavy sites, competitive niches |
coreyhaines31/marketingskills | ~30 marketing skills (CRO, copywriting, ads, popups, email, paywalls, etc.) | marketing/lead-gen, SaaS-app, training/paid-course |
jonathimer/devmarketing-skills | 33 developer-marketing skills (persona, docs-as-marketing, technical tutorials, etc.) | doc-site, SaaS-app for developers |
Skill selection workflow (run at session start)
After the user confirms site type, for each pack relevant to that site type:
1. List available sub-skills: npx skills add owner/repo --list 2. Propose a curated subset based on site type and the phases this skill will execute. Match each phase's needs to specific sub-skills the listing returns. 3. Confirm with the user via ask_user_input_v0. Use multi-select when the proposed list has more than 3 items, single-select (install-as-proposed | let-me-modify | skip-this-pack) otherwise. 4. Bulk install the agreed subset: npx skills add owner/repo --skill A B C
Rules:
- Sub-skill names live in the pack, not in this SKILL.md. Always query
--listfor the current state. Pack contents change. - Never run
npx skills add owner/repowithout--skill(that installs everything). - Site type → packs mapping (which packs to enumerate, sub-skills still selected per workflow):
doc-site: claude-seo, web-quality-skills, trailofbits, seo-geo-claude-skills, devmarketing-skillsmarketing/lead-gen: claude-seo, web-quality-skills, trailofbits, seo-geo-claude-skills, marketingskillsSaaS-app: all sixtraining/paid-course: claude-seo, web-quality-skills, trailofbits, marketingskillspersonal-portfolio: claude-seo, web-quality-skills, trailofbits, seo-geo-claude-skills (lightweight subset)- If the user later requests a phase that needs a sub-skill not yet installed, run the workflow again for that single sub-skill rather than re-installing the whole subset.
This avoids importing 80+ skills the user does not need, avoids going stale on sub-skill names, and avoids overfitting to a single pack version.
When delegating during a phase, do not duplicate work this skill orchestrates. Call the specialist with a narrow scope (e.g., "run only the security headers sub-audit on URL X").
Copywriting voice and humanizer pass
Every site has visible marketing copy (hero, features, CTAs, meta descriptions, OG descriptions, blog posts, 404 page text). Two layers of polish are mandatory before launch:
1. Define TONE.md once per site
Ask the user (ask_user_input_v0): "Does this site already have a TONE.md?" (yes-already-exists | no-create-from-template | skip-use-default).
If creating: write it to .agents/TONE.md or repo root TONE.md. See references/templates.md (section "TONE.md template") for the structure.
TONE.md specifies: voice (terse, contrarian, etc.), forbidden patterns (e.g., "delve", "crucial", em dashes, AI-sounding openers), sentence length preference, audience reading level, examples of good and bad sentences from the user's own writing.
2. Run a humanizer pass in the matching language
After every drafting step (whether by a copywriting skill, by hand, or by Claude directly), run a humanizer to strip AI patterns.
Ask the user (ask_user_input_v0) for the site's primary audience language at the start of the session if not already known:
english-global→npx skills add https://github.com/blader/humanizer --skill humanizerfrench→ usesamber/humaniseur-fr(custom French humanizer) or equivalent French-tuned skillother→ install matching humanizer if available; otherwise the skill writes a short language-specific anti-pattern checklist inline
Apply the humanizer to: hero copy, feature descriptions, CTA buttons, meta descriptions, OG/Twitter card descriptions, blog posts, email signup confirmations, 404 page text. Skip for legal pages (mentions légales, CGV) since they have rigid wording requirements.
3. Always reference TONE.md when invoking copywriting skills
When delegating to any copywriting or content-writing sub-skill (selected at invocation per the skill selection workflow), include TONE.md in the prompt context. Pass voice constraints explicitly: "Follow .agents/TONE.md. Avoid the listed patterns. Apply the humanizer after drafting."
Browser interaction preference
Many checks require a real browser (Lighthouse runs, securityheaders.com scan, opengraph.xyz validation, Twitter card validator, mobile viewport, screen reader smoke, Network tab inspection).
Always prefer the Claude Chrome extension. Fall back to Playwright only if the Chrome extension is unavailable. If neither is available, ask the user (ask_user_input_v0) whether to skip browser checks entirely or wait until they enable one.
Verification tools
Most checks are doable from the command line without third-party services. Use these tools inline at every phase. Don't trust panels in Cloudflare/Vercel/Google dashboards alone, verify with curl.
DNS (Phase 1):
dig +short A example.com # A record
dig +short AAAA example.com # AAAA (IPv6)
dig +short MX example.com # MX (mail)
dig +short TXT example.com # SPF + verification TXT
dig +short TXT _dmarc.example.com # DMARC
dig +short TXT default._domainkey.example.com # DKIM (selector varies)
dig +short CAA example.com # CAA
dig +dnssec example.com | grep RRSIG # DNSSEC activeTLS / HTTPS (Phase 1):
curl -sIL https://example.com | head # follow redirects
curl -sI https://www.example.com # check www handling

---
Phase 1: Domain & Infrastructure
Most of this is one-click via Cloudflare's dashboard if the domain is on Cloudflare.
Ask first: "Is the domain already on Cloudflare with the standard config from previous launches?" (yes-standard | yes-needs-review | no-fresh-setup)
Checklist:
- [ ] Cloudflare: proxy ON for apex + www, TLS 1.3 minimum, "Always Use HTTPS" enabled, HSTS preload enabled in Cloudflare SSL/TLS settings
- [ ] DNS A/AAAA or CNAME pointing to Vercel (verify with
dig +short A example.com) - [ ] MX records for Google Workspace (verify with
dig +short MX example.com) - [ ] SPF, DKIM, DMARC records (verify all 3 with the dig commands above)
- [ ] CAA records restricting cert issuance (verify with
dig +short CAA example.com) - [ ] DNSSEC enabled at registrar level (verify with
dig +dnssec) - [ ] Vercel: project linked to repo, prod + preview env vars set, custom domain attached, prod and preview aliases correct
- [ ] Decide www vs apex canonical, configure 308 redirect for the non-canonical (verify with
curl -sIL https://www.example.com) - [ ] Custom 404 page renders (verify with
curl -sI https://example.com/does-not-exist) - [ ] Custom 500 page exists (cannot easily verify without forcing an error, ask user)
- [ ] If migration: 301 redirect map for every old URL (loop verification with
curl -sILper URL)
Backups
If you don't configure backups at launch, you never will. Do it now.
Ask the user (ask_user_input_v0): "Which data stores does this app write to?" (database-only | database-plus-file-storage | file-storage-only | stateless-no-persistent-data). If stateless-no-persistent-data, skip this section.
Database:
- [ ] Automated daily backups enabled at the provider level (Neon, Supabase, PlanetScale, Railway, RDS — each has a one-click toggle). Verify by opening the backup panel and confirming the last backup timestamp is recent.
- [ ] Retention policy set to ≥30 days
- [ ] Point-in-time recovery (PITR) enabled if available (Neon, Supabase, RDS all support it)
- [ ] Off-site copy: if the provider stores backups in the same region as the primary, configure cross-region replication or a nightly export to a separate storage account (S3, R2, GCS)
- [ ] Restore drill performed before launch: pick a recent backup, restore to a staging database, verify row counts and a sample query. A backup you haven't tested is not a backup.
File storage (if applicable — S3, R2, GCS, Cloudflare Images):
- [ ] Versioning enabled on the primary bucket
- [ ] Cross-region replication or a scheduled sync to a secondary bucket. Backblaze B2 is a cheap, reliable option for off-site copies (significantly cheaper than S3/GCS egress). Use
rcloneto sync from S3/R2/GCS → B2 on a daily cron. - [ ] Lifecycle rule: transition old versions to cheaper storage after 30 days, delete after 90 days (adjust to cost tolerance)
Secrets / environment variables:
- [ ] All env vars documented and stored in a secrets manager (1Password, Doppler, Vault, or equivalent). Not in a
.envfile on someone's laptop. - [ ] Verify: if every engineer's machine burned tonight, could a new team member restore prod from scratch using only the secrets manager + git?
Monitoring:
- [ ] Set up an alert (email or Slack) if the daily backup job fails. Most providers support this natively; configure it before closing the backup panel.
---
Phase 2: Analytics & Observability
Most third-party integrations are one-click via Cloudflare or Vercel.
For the conditional tools (Crisp, Sentry, BetterStack), use `ask_user_input_v0` to confirm per site type. See references/decisions.md for the observability tier matrix.
Always-on:
- [ ] Google Analytics 4: property created, measurement ID embedded, gated behind CNIL consent
- [ ] PostHog: based on user's earlier answer:
- If
hogpost.samber.dev: configure client withapi_host: "https://hogpost.samber.dev"and verify CORS allows the new domain (test with browser console orcurl -H "Origin: https://newsite.com" -I https://hogpost.samber.dev/decide) - If
set-up-new-proxy: add path rewrite innext.config.jstous.i.posthog.comandus-assets.i.posthog.com, init client withapi_host: "/ingest" - If
skip-PostHog: skip - [ ] Google Search Console: site verified (DNS TXT or HTML file), sitemap submitted
- [ ] Bing Webmaster Tools: site verified, sitemap submitted, IndexNow key file at
/{key}.txton root (verify withcurl -sI https://example.com/{key}.txt) - [ ] Ahrefs: site added to dashboard for tracking
- [ ] Add the site to the internal stats spreadsheet (PostHog properties registry + GitHub Sponsors tracking sheet if applicable)
Brand monitoring (Google Alerts):
For each alert, use these settings: Frequency: once a day | Sources: Automatic | How many: All results | Region: Any region
Set up one alert per keyword via alerts.google.com:
- [ ] Domain name (e.g.,
example.com) - [ ] Brand or product name (quoted if multi-word, e.g.,
"My Brand") - [ ] Key feature or library names if the site documents a project
- [ ] Competitor brand names (optional — ask user via
ask_user_input_v0:yes-monitor-competitors|skip)
Ask the user: "Which additional keywords to monitor?" (product-name-only | domain-plus-brand | full-set-with-competitors | custom-list)
Developer community monitoring (F5bot) — for `doc-site` and `SaaS-app` targeting developers:
F5bot (f5bot.com) monitors Reddit, Hacker News, and Lobste.rs for keyword mentions and sends email alerts. Free, no API required.
Set up one keyword per line at f5bot.com/add:
- [ ] Brand or product name
- [ ] Domain name (catches link shares)
- [ ] Key feature or library names
- [ ] Common misspellings if applicable
Competitor analysis (`marketing/lead-gen`, `SaaS-app`, `training/paid-course` only):
Before writing copy, setting up ads, or planning content, run a competitor analysis to understand what is already working in the market — positioning, messaging angles, CTA patterns, pricing presentation, and content strategy.
Use a deep research tool or a competitor analysis skill if one is available in the toolchain. Ask via ask_user_input_v0:
- "Do you already have competitor names/URLs to analyze?" (
yes-provide-list|no-discover-for-me|skip) - If
yes-provide-list: ask the user to paste 2-5 names or URLs (free text) - "What are we looking to extract?" (
positioning-and-messaging|pricing-strategy|content-and-seo|full-spectrum)
Feed the output into:
- Phase 5 keyword strategy (target queries they rank for but you can outrank or flank)
TONE.mdvoice calibration (deliberately differentiate from the dominant tone in the category)- Phase 6 OG copy and CTA language (borrow proven frames, don't clone verbatim)
- Copywriting sub-skills invoked later (pass the competitor snapshot as context)
Conditional (ask user, default per site type from `references/decisions.md`):
- [ ] Crisp
- [ ] Sentry
- [ ] BetterStack
---
Phase 3: Legal & Compliance (FR)
Ask first: "Is this site subject to French law?" (yes-FR-operator-or-audience | no-EU-only | no-non-EU). If no, ask whether GDPR or equivalent applies and adjust.
For FR sites:
- [ ] Mentions légales page (mandatory, fines up to 75k€ per omission)
- [ ] CGV (Conditions Générales de Vente) if commercial activity
- [ ] Privacy policy
- [ ] Terms of service
- [ ] CNIL-compliant cookie consent that gates GA4, PostHog, Crisp, Sentry script loading (not just a banner that always loads trackers). Use a CMP (Axeptio, Tarteaucitron, or custom). Verify with browser Network tab: no tracker fires before explicit consent.
---
Phase 4: Security
Delegate the deep audit to trailofbits/skills. The items below are the must-pass checklist.
Ask first: CSP tightness level (strict-default-src-none | balanced-allow-self | permissive-for-marketing). See references/templates.md for the CSP template per level.
- [ ] CSP: target chosen tightness level. No
'unsafe-inline'for scripts (use nonces). Verify withcurl -sI ... | grep -i content-security-policy. - [ ] HSTS:
max-age=31536000; includeSubDomains; preload. Submit to hstspreload.org. Verify withcurl -sI ... | grep -i strict-transport. - [ ] X-Frame-Options:
DENY - [ ] X-Content-Type-Options:
nosniff - [ ] Referrer-Policy:
strict-origin-when-cross-origin - [ ] Permissions-Policy: deny camera, microphone, geolocation, payment unless used
- [ ] Run all headers in one go:
curl -sI https://example.com | grep -iE 'content-security|strict-transport|x-frame|x-content-type|referrer-policy|permissions-policy' - [ ] securityheaders.com: target A+ (verify via Claude Chrome extension or
curl https://securityheaders.com/?q=URLand parse) - [ ] observatory.mozilla.org: target 90+ (via Chrome extension)
- [ ] Run
trailofbits/skillssecurity audit on the codebase - [ ] Verify no leaked secrets in client bundle: open Chrome DevTools Network tab via Claude Chrome extension, grep response bodies for
sk_,pk_,AKIA,ghp_,Bearer
---
Phase 5: SEO & GEO
Delegate the full audit to AgriciDaniel/claude-seo. The items below are the orchestration list.
See references/templates.md for robots.txt, llms.txt, and manifest.json templates. See references/decisions.md for the AI scraper policy matrix by site type.
- [ ]
/robots.txtpresent, references sitemap (verify withcurl -s https://example.com/robots.txt) - [ ]
/sitemap.xmlpresent, valid (verify withcurl -s https://example.com/sitemap.xml | head -40). Sitemap-index with per-language sitemaps if multilingual. - [ ]
/llms.txtpresent (per llmstxt.org spec, verify withcurl -s https://example.com/llms.txt) - [ ] AI scraper policy encoded in
robots.txt. Apply the matrix fromreferences/decisions.mdbased on site type, then ask user via `ask_user_input_v0` to confirm each non-default decision. - [ ] Schema markup (JSON-LD):
Organization+WebSite+BreadcrumbListsite-wide; per-page types where applicable (SoftwareApplicationfor lib homepages,Articlefor blog posts,FAQPagefor FAQs,Personfor author bio). Verify withcurl -s URL | grep -A 50 'application/ld+json'. Validate structured data via Google Rich Results Test (<https://search.google.com/test/rich-results>) and Schema.org Validator (<https://validator.schema.org>) — Rich Results Test checks eligibility for rich snippets; Schema.org Validator catches spec violations that Google may silently ignore. - [ ] Meta tags per page: unique
<title>(50-60 chars), unique<meta description>(150-160 chars),<link rel="canonical">,<meta name="robots">if needed - [ ]
hreflangtags on every page if multilingual (every language version declares all alternates including self). Verify withcurl -s URL | grep -i hreflang. - [ ] Keyword analysis using both Google Trends and Ahrefs (they answer different questions, not interchangeable):
- Google Trends (trends.google.com): trajectory (rising vs declining), geographic distribution (especially FR vs international split), seasonal patterns, related queries breakout, head-to-head comparison of 2-5 candidate keywords. Use Trends to validate direction and timing of the SEO bet.
- Exploding Topics (explodingtopics.com): surfaces emerging trends weeks or months before they peak in Google Trends. Use to identify rising queries before competition solidifies and to validate that target keywords aren't already on the decline.
- Answer The Public (answerthepublic.com/en): maps search questions, comparisons, and related queries around a seed keyword. Use to uncover long-tail intent clusters, populate FAQ schema, and identify content gaps.
- Ahrefs Keywords Explorer: monthly volume, keyword difficulty, SERP analysis, CPC, parent topic, traffic potential. Use Ahrefs to size the opportunity in absolute terms.
- Combined output: a ranked shortlist of 3-5 target queries per page, with rationale (volume × difficulty × trajectory × intent match).
- Delegate to whichever keyword-research sub-skill was installed at session start (selected from the installed packs via the skill selection workflow; typical sources are the SEO+GEO and marketing packs).
- [ ] AI visibility audit via productrank.ai: open productrank.ai in a browser, submit multiple category or product searches, run the full AI SEO report. It audits how the site appears in AI-generated answers (ChatGPT, Perplexity, Gemini, Claude). Flag any zero-visibility categories and surface content gaps the AI graders identify.
- [ ] Typo and grammar pass on all visible text content
- [ ] Backlink profile audit: run Ahrefs Backlink Checker and Moz Link Explorer to assess domain authority and surface toxic or broken inbound links before launch — especially critical on migrations to ensure old-domain equity transfers correctly
- [ ] Internal linking audit: every important page reachable in ≤3 clicks from the homepage
---
Phase 6: Open Graph & Social Preview
Verify all OG and Twitter tags with: curl -s URL | grep -iE 'og:|twitter:'
- [ ]
og:title,og:description,og:url,og:type,og:site_name - [ ]
og:image1200×630px, absolute URL,og:image:widthandog:image:heightdeclared,og:image:altset - [ ] Per-page `og:image`, not one global. For doc sites: generate dynamically from page title. For blog posts: per-article custom image.
- [ ]
og:locale+og:locale:alternatefor each language if multilingual - [ ] Twitter Cards:
twitter:card=summary_large_image,twitter:title,twitter:description,twitter:image,twitter:site(handle) - [ ] Validate with opengraph.xyz (covers FB, LinkedIn, Slack, Discord, WhatsApp previews) via Claude Chrome extension
- [ ] Validate with Twitter's card validator
- [ ] Manual check: paste URL in a LinkedIn DM, a Slack channel, a Discord, an iMessage. Preview must render correctly in all.
---
Phase 7: Favicons & Web Manifest
See references/templates.md for the manifest.json template.
Generate from a single 1024×1024 source PNG using realfavicongenerator.net or favicon.io.
Minimum modern set:
- [ ]
/favicon.ico(multi-res 16/32/48). Verify withcurl -sI https://example.com/favicon.ico. - [ ]
/favicon.svgwith embedded<style>@media (prefers-color-scheme: dark) { ... }</style>for dark mode. Verify withcurl -sI https://example.com/favicon.svg. - [ ]
/favicon-96x96.png(PNG fallback) - [ ]
/apple-touch-icon.png180×180px, no transparency, opaque background. Verify withcurl -sI. - [ ]
/web-app-manifest-192x192.png(Android PWA icon) - [ ]
/web-app-manifest-512x512.png(Android splash) - [ ]
/manifest.jsonreferencing both PNGs, withtheme_color,background_color,name,short_name,display. Verify withcurl -s https://example.com/manifest.json | jq ..
Skip (deprecated):
mstile-*.png(Windows tiles)safari-pinned-tab.svg(deprecated since macOS Big Sur)favicon-16x16.png/favicon-32x32.png(covered by.icoand.svg)
HTML head verification:
curl -s https://example.com/ | grep -iE 'rel="icon"|rel="apple-touch-icon"|rel="manifest"'---
Phase 8: Quality Gates
Delegate to addyosmani/web-quality-skills. The skill covers 150+ Lighthouse audits across performance, accessibility, SEO, and best practices.
- [ ] Unlighthouse site-wide crawl:
npx unlighthouse --site {site}— crawls all pages and runs Lighthouse on each. Surface pages below 90 on any axis before the per-URL checks. - [ ] Lighthouse all 4 axes, mobile mode: target ≥90 on each (perf, a11y, best practices, SEO)
- [ ] Lighthouse all 4 axes, desktop mode: target ≥95 on each
- [ ] Core Web Vitals field data (CrUX via PageSpeed Insights): LCP < 2.5s, INP < 200ms, CLS < 0.1, on both mobile and desktop
- [ ] Accessibility (WCAG 2.2 AA via
web-quality-skills): keyboard nav works for every interactive element, focus rings visible, color contrast ≥4.5:1 for text, all images havealt, heading hierarchy is monotonic (H1 → H2 → H3), ARIA labels on icon-only buttons - [ ] Real mobile device test (not just devtools emulator). Use Claude Chrome extension on mobile viewport on a real device or BrowserStack.
- [ ] Cross-browser smoke test: Chrome, Safari, Firefox latest stable
- [ ] Print stylesheet sanity (Cmd+P should not break layout)
---
Phase 9: Ecosystem Cross-linking
Internal cross-linking between owned properties. High-leverage SEO action for any multi-domain owner.
Ask the user: "List the other domains in your ecosystem that are topically relevant to this new site." Then for each one:
- [ ] Add a link from the existing site (footer / nav / "other projects" section) to the new site, where topically relevant
- [ ] Add a link to the new site in the README of the matching GitHub repo, if it documents a library
- [ ] Verify reciprocal links: every link added points back where appropriate
- [ ] If the new site documents a Go lib, link from related lib docs
Do not over-link. Only cross-link where topically relevant. A doc site for a logging lib should not link to a personal blog about cycling.

Phase 10: Set up weekly SEO maintenance sub-agent
After launch, set up a Hermes agent or Claude Cowork agent that runs weekly to monitor SEO health and surface action items.
See references/weekly-seo-agent.md for the full agent definition. Copy it into .claude/agents/weekly-seo.md in the site's repo (or a dedicated ops repo). The agent uses these MCP connectors:
- Ahrefs MCP (backlinks, rankings, keywords)
- PostHog MCP (analytics correlation, AI bot traffic)
- Web search (SERP monitoring, competitor checks)
- Google Search Console (via community MCP or
curlwith service account credentials)
Ask the user via ask_user_input_v0: "Set up the weekly SEO agent now?" (yes-create-agent-file | yes-but-defer | skip-for-now).
When MCP are not available, use Claude for Chrome extension.
---
Output format
At the end of a full run, output a status report grouped by phase:
Phase 1: Domain & Infrastructure [9/10 pass]
✓ Cloudflare proxy on
✓ DNS records configured
...
✗ DMARC missing. Fix: add TXT record at _dmarc.example.com with policy v=DMARC1; p=quarantine;...
Phase 2: Analytics & Observability [6/7 pass]
...Followed by three lists, in order:
1. Blockers (must fix before launch) 2. Recommended fixes (should fix before announcing) 3. Optional improvements (post-launch)
End by asking via ask_user_input_v0: "Which list do you want to tackle next?" (blockers | recommended | optional | done-for-now).

Decisions and matrices
Repeating decisions for site launches. Apply the matrix based on the site type the user confirmed at the start of the session. When a decision is ambiguous or borderline, ask the user via ask_user_input_v0 rather than assuming.
AI scraper policy by site type
Decide which AI training and AI-search crawlers to allow per site type. Encode the decision in robots.txt (see templates.md).
Marketing / lead-gen page (consulting, training landing)
Allow all AI scrapers. Your conversion copy is intellectual property; training it into LLMs that may recommend competitors is anti-value. But AI citations on a sales page is good.
Paid course / training page
Block all. Content is the product.
Personal portfolio / personal blog
Allow the citing crawlers (ClaudeBot, GPTBot, PerplexityBot, Google-Extended). Useful for "who is X" or "what does X work on" queries.
SaaS app
- App subdomain (e.g., app.example.com): block all AI scrapers. The app is gated, no value in scraping.
- Landing / marketing subdomain: apply the marketing rules above.
Default when site type is unclear
Block all. Ask the user. Better to surface the decision than to silently expose content to crawlers.
---
Observability tier by site type
Decide which analytics and observability tools to install. Always confirm conditional tools with ask_user_input_v0.
Doc site / lib homepage
| Tool | Install? |
|---|---|
| GA4 | Yes |
| PostHog (via hogpost.samber.dev or new proxy) | Yes |
| Google Search Console | Yes |
| Bing Webmaster + IndexNow | Yes |
| Ahrefs | Yes |
| Crisp | No (doc readers don't chat, it tanks Lighthouse) |
| Sentry | No (static, no app logic to crash) |
| BetterStack | No (Vercel uptime is enough) |
Marketing / lead-gen
All of the doc-site tools, plus:
| Tool | Install? |
|---|---|
| Crisp | Yes (conversion intent) |
| Sentry | Yes if there are forms or interactive elements |
| BetterStack | Only if you publish an SLA |
SaaS app
All of the above, plus:
| Tool | Install? |
|---|---|
| Sentry | Mandatory |
| BetterStack | Yes, with a public status page |
| Crisp or Intercom | Yes |
Personal portfolio
| Tool | Install? |
|---|---|
| GA4 | Yes |
| PostHog | Yes |
| GSC | Yes |
| Ahrefs | Optional |
| Crisp | No |
| Sentry | No |
| BetterStack | No |
---
www vs apex canonical
Default: apex is canonical, www redirects to apex via 308.
Exception: if the site is hosted on a platform that requires CNAME (which cannot be set on apex per DNS RFCs), the platform's flattening / ALIAS / ANAME feature is used. Cloudflare handles this transparently with CNAME flattening, so apex remains canonical.
Verify with:
curl -sIL https://www.example.com
# Expect: 308 → https://example.com---
CSP tightness level by site type
Three levels. Pick one with ask_user_input_v0 at the start of Phase 4.
strict-default-src-none
For doc sites, personal portfolio, SaaS app. Whitelist every source explicitly. No 'unsafe-inline'. Use nonces for any required inline scripts.
balanced-allow-self
For marketing pages with embeds (YouTube, Calendly, etc.). default-src 'self', then allow specific third parties.
permissive-for-marketing
Last resort for legacy marketing pages with many third-party scripts (HubSpot, Drift, etc.). Document why and plan to tighten.
See templates.md for the actual CSP strings per level.
---
When a decision is unclear
Always default to asking via ask_user_input_v0 with the matrix options as tappable choices. Never silently apply a guess.
Templates
File and header templates for site launches. Apply per the matrices in decisions.md.

CSP templates
Three tightness levels. Pick per the matrix in decisions.md.
strict-default-src-none
For doc sites, personal portfolio, SaaS apps with bundled assets only.

style-src 'unsafe-inline'is unfortunately required by most modern frameworks (Tailwind in dev, styled-components, etc.). Tighten with hashes if feasible.- Replace
{NONCE}with a per-request random value generated server-side (Next.js middleware can do this). connect-srcincludeseu.i.posthog.comas a fallback ifhogpost.samber.devproxy is unavailable.
balanced-allow-self
For marketing pages with embeds.

TONE.md template
Place at .agents/TONE.md or repo root. Fill in based on the user's writing samples and preferences.
# Tone of voice: [Site name]
## Audience
- Primary: [e.g., senior Go developers shipping production systems]
- Secondary: [e.g., engineering managers evaluating libraries]
- Reading level: [e.g., technical, no hand-holding]
- Language: [e.g., English, with some French for FR-specific pages]
## Voice
- Direct, dense, no filler.
- Contrarian when warranted.
- Data-grounded: claims need numbers or links.
- Concrete over abstract: prefer "200ms p95" to "fast".
- Assume reader has context, skip primers.
## Forbidden words and patterns
- AI-sounding openers: "In today's fast-paced world", "Let's dive into", "It's worth noting that".
- Vague adjectives: "crucial", "essential", "powerful", "robust", "comprehensive", "seamless", "innovative".
- Empty verbs: "delve into", "leverage", "utilize", "facilitate".
- Hedging: "might potentially", "may possibly", "kind of", "sort of".
- Em dash character ("—") forbidden. Use commas, parentheses, or two sentences.
- Marketing fluff: "game-changing", "revolutionary", "next-generation", "world-class".
## Required patterns
- One concrete example per claim.
- Numbers when possible. Prefer "20% faster" over "much faster".
- Code samples for technical content. Short, runnable, idiomatic.
## Sentence and paragraph rules
- Average sentence length: 12-18 words.
- Max paragraph length: 4 sentences.
- One idea per paragraph.
- Section headers are statements, not questions.
## Good examples (from existing content)
- "Product XYZ hit $1m ARR without paying for ads. The community wants feature-ABC done right."
- "Tool XYZ gives 50× benchmark speedups and 5% production gains. Both numbers are true. Only one matters."
## Bad examples (to avoid)
- "Product XYZ is a powerful, comprehensive productivity tool that leverages documentation to seamlessly empower designers."
- "In today's fast-paced development landscape, choosing the right productivity tool is crucial."
## Address form (FR only)
- `tu` vs `vous` must be chosen deliberately and applied consistently site-wide. Mixed forms on the same site are a copywriting error.
- Default by site type:
- `doc-site` (OSS lib, developer tools): **tu** — developer community is informal; "vous" feels corporate and creates distance.
- `SaaS-app` (B2B, enterprise): **vous** — default to formal unless the product targets solo developers or the brand is explicitly casual.
- `marketing/lead-gen` (consumer-facing): **tu** if the audience is young or tech-savvy; **vous** if the audience is professional or older.
- `training/paid-course`: **tu** — learning context is personal; "vous" creates unnecessary formality.
- `personal-portfolio`: **vous** — professional register by default.
- Ask the user explicitly if the default does not fit: "Which address form?" (`tu` | `vous` | `already-specified-in-TONE.md`)
- Record the chosen form in TONE.md under `Address form: tu | vous` and enforce it in every copy review and humanizer pass.
## Localization notes
- FR content: use guillemets « » not quotes, use non-breaking spaces before `: ; ? !`, avoid anglicisms ("faire du sens", "adresser un problème").
- EN content: US spelling.The skill should read TONE.md at the start of any copywriting task and pass its constraints to any delegated copywriting skill. After drafting, run the humanizer in the matching language.
Weekly SEO maintenance sub-agent
Definition for a Hermes agent or Claude Cowork agent that runs weekly post-launch to monitor SEO health and surface action items.
Setup
1. Copy the agent definition (the block at the bottom of this file) into .claude/agents/weekly-seo.md in the site's repo (or in a dedicated ops repo if you manage multiple sites). 2. Confirm the following MCP servers are connected in Claude Code / Cowork:
- Ahrefs MCP (required, for backlinks and rankings)
- PostHog MCP (required, for traffic correlation)
- Google Search Console (recommended, via community MCP such as
gsc-mcp; if no MCP, fall back tocurlwith a service account credential file) - Web search (built-in, for SERP feature checks and competitor monitoring)
3. Confirm the agent has access to the project source code if they apply to the site's content. 4. Schedule weekly execution. Three options:
- Cron +
claude --dangerously-skip-permissions -p "/agents weekly-seo"(Linux/macOS, only if running in a trusted environment) - Hermes agent
- Claude Cowork agent
- GitHub Actions weekly schedule, posting the report to a Slack channel
- Manual invocation each Monday morning
When MCP are not available, use Claude for Chrome extension or a browser
What the agent does
Run all 10 tasks below in one weekly pass. Each task produces a section of the final report.
1. Ranking changes (GSC + Ahrefs)
- Pull top 50 queries by impressions for the last 7 days from Google Search Console.
- Compare positions, impressions, clicks, and CTR to the prior 7 days.
- Flag any (page, query) pair that:
- Dropped more than 5 positions
- Lost more than 20% impressions
- Lost more than 30% clicks while position is stable (CTR collapse, often a SERP feature stealing clicks)
- Output: ordered list of (page, query, delta, hypothesis, recommended action).
2. Page-2 opportunities (GSC)
- Identify queries ranking positions 11 through 20 with more than 100 impressions in 7 days.
- For the top 5: fetch the current page 1 SERP via
web_searchand compare structure, depth, and recency of the top 3 results to the site's current content. - Output: content gap analysis with specific edit suggestions (add FAQ section, expand introduction, add benchmark table, etc.).
3. New backlinks (Ahrefs MCP)
- Pull new referring domains acquired in the last 7 days.
- Categorize each: high authority (DR > 50), niche relevant (matches site topic), neutral, spam.
- Flag spam links for potential disavow file submission.
- Output: list of new links with category, plus a draft disavow line for any spam.
4. Lost backlinks (Ahrefs MCP)
- Pull referring domains lost in the last 7 days.
- For losses from domains with DR > 40 or known niche relevance: draft outreach email asking why and offering to fix any broken links.
- Output: list of lost links plus draft outreach for high-value losses.
5. Core Web Vitals drift (GSC + PageSpeed Insights)
- Pull the Core Web Vitals report from GSC (mobile and desktop separately).
- Compare to the prior week.
- Flag any URL group that crossed from "Good" to "Needs improvement" or "Poor".
- For each flagged group: run PageSpeed Insights via
web_fetchon a representative URL and identify the failing metric (LCP, INP, or CLS) and likely cause. - Output: list of affected URL patterns with proposed fixes.
6. Indexation health (GSC)
- Pull the Page Indexing report.
- Compare "Indexed" and "Not indexed" counts week-over-week.
- For new entries in "Not indexed", group by reason (Discovered not indexed, Crawled not indexed, Excluded by noindex, Soft 404, etc.).
- Output: per-reason summary with recommended fix.
7. AI bot traffic (PostHog MCP)
- Query PostHog for sessions where the user agent matches
(GPTBot|ClaudeBot|PerplexityBot|Google-Extended|anthropic-ai|ChatGPT-User|CCBot|Bytespider|Amazonbot). - Compare counts to the prior week, broken down by bot.
- If the site type is
doc-siteand counts are growing: positive signal, surface as a metric. - If the site type is
marketing/lead-genorpaid-courseand any AI bot has nonzero traffic: verifyrobots.txtis actually blocking by fetchinghttps://example.com/robots.txtand grepping for the bot. If it should block but isn't, this is a blocker. - Output: per-bot weekly count with delta, plus blockers if any bot is reaching pages it should not.
8. Competitor SERP monitoring
- For the top 5 target keywords (configured per site in a YAML or JSON file the agent reads): capture the current top 3 SERP results via
web_search. - Compare to the prior week's snapshot (the agent should persist last week's snapshot).
- Flag new entrants in the top 3 (potential threat) and dropped competitors (potential opportunity).
- Output: per-keyword SERP delta with strategic note.
9. Content freshness audit
- List pages older than 6 months (use Git log on the content files, or GSC "Last crawled" date) with declining clicks over the trailing 4 weeks.
- For the top 5 by lost clicks: recommend a refresh priority based on remaining traffic, topic stability, and competitor SERP activity.
- Output: refresh queue with effort estimate.
10. Schema and structured data validity
- Sample 5 pages at random plus the homepage.
- For each, extract the JSON-LD via
curl -s URL | grep -A 200 'application/ld+json'. - Validate against schema.org by checking required properties for the declared
@type(the agent has a local rules file or fetches schema.org definitions). - Output: list of breakages with file path and fix.
11. Stats memory snapshot
At the end of every run, append a row to weekly-seo/memory/stats.csv (create if missing):
date,indexed_pages,clicks_7d,impressions_7d,avg_position,new_backlinks,lost_backlinks,lcp_ms,cls,inp_ms,ai_bot_sessionsThis builds a longitudinal record the agent can query in future runs for trend analysis (e.g., 4-week rolling average, detecting regressions that don't show up in week-over-week deltas).
Also append to weekly-seo/memory/keywords.csv (one row per target keyword per run):
date,keyword,position,impressions,clicks,ctr,page_urlThese two files are the agent's persistent memory. Never truncate or overwrite them. Always append.
12. Change log (what worked)
Read weekly-seo/memory/changelog.md (create if missing). This file is a running log of changes applied to the site and their measured impact.
On every run:
1. For each entry in the changelog with status: pending-validation and a measure_after date that has now passed: pull the relevant metric (rankings, clicks, CWV, etc.) for the affected page or keyword and compare to the baseline recorded at change time. Update the entry with status: validated or status: no-effect, the measured delta, and a one-sentence conclusion. 2. At the end of the report, emit a "What worked" section listing only validated entries with positive delta, ordered by impact. This is the institutional memory of SEO wins.
When instructed to log a change (user or orchestrator passes a change description):
Append to weekly-seo/memory/changelog.md:
## YYYY-MM-DD — <short title>
- **Page/scope**: `https://example.com/page` (or "site-wide")
- **Change**: one-sentence description of what was done
- **Hypothesis**: why this should improve the metric
- **Baseline**: clicks=N, position=N, LCP=Nms (snapshot at time of change)
- **Metric to watch**: clicks | position | LCP | CLS | INP | backlinks
- **Measure after**: YYYY-MM-DD (typically 3–4 weeks out)
- **Status**: pending-validationNever delete changelog entries. no-effect entries are as valuable as wins — they prevent re-testing the same hypothesis.
Output format
The agent produces a single Markdown report saved to weekly-seo/YYYY-MM-DD.md and (optionally) posted to Slack.
Report structure:
# Weekly SEO Report: example.com (YYYY-MM-DD)
## Summary
- Indexed pages: N (delta vs last week)
- Total clicks (7d): N (delta)
- Total impressions (7d): N (delta)
- New backlinks: N | Lost: N
- AI bot sessions: N (delta)

name: weekly-seo
description: Weekly SEO maintenance and monitoring for a launched site. Run every Monday. Pulls data from Google Search Console, Ahrefs, PostHog, and web search to monitor rankings, backlinks, Core Web Vitals, indexation, AI bot traffic, competitor SERPs, content freshness, and schema validity. Produces a Markdown report with blockers, should-fix items, and opportunities.
tools: WebFetch, WebSearch, Bash, Read, Write
---
You are a weekly SEO maintenance agent for a single launched site. Your job is to run 12 health-check tasks every Monday and produce a structured Markdown report.
## Configuration
Read `weekly-seo/config.yml` for site-specific config: domain, target keywords (top 5), GSC property ID, Ahrefs project ID, PostHog project ID, Slack webhook URL (optional).
## Tasks
[Run all 12 tasks defined in references/weekly-seo-agent.md of the site-launch-checklist skill. For each task, follow the detailed instructions there.]
Tasks 11 and 12 are mandatory on every run:
- **Task 11 (stats memory)**: append to `weekly-seo/memory/stats.csv` and `weekly-seo/memory/keywords.csv`. Never skip.
- **Task 12 (changelog validation)**: check `weekly-seo/memory/changelog.md` for `pending-validation` entries whose `measure_after` date has passed; update their status; emit the "What worked" section in the report.
## MCP usage
- Ahrefs MCP: tasks 1, 3, 4
- PostHog MCP: task 7
- Google Search Console (via community MCP or curl): tasks 1, 2, 5, 6
- Web search (built-in): tasks 2, 8
If an MCP is unavailable, fall back to Claude for Chrome, to a web browser, to the equivalent API call via `curl` or `web_fetch` with credentials stored in `.env` (do not commit). Surface any data-source unavailability in the report header so the user knows the run was partial.
## Output
Write the report to `weekly-seo/YYYY-MM-DD.md`. If a Slack webhook is configured, post the Summary + Blockers sections to Slack.
## Tone
Terse, action-oriented. Each blocker is one sentence stating the problem and one sentence stating the fix. No filler.Config file template
Place at weekly-seo/config.yml in the site's repo.
