_dns-cloudflare

_dns-cloudflare is a skill for Claude Code from flavien-ia/hypervibe-harness. It costs 51 tokens per session (1,313 once invoked), scanned A, original, Apache-2.0.

A special instruction for domains registered through Cloudflare. Cloudflare Registrar is the service where the domain name was bought, while Cloudflare DNS manages its settings.

In plain words
What is it for?
Handling the Cloudflare-registrar case during an add-domain setup.
Why use it?
It prevents an unnecessary nameserver change when the domain is already registered with Cloudflare; the setup only needs to check that the domain's zone exists through Cloudflare's web API.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

_dns-cloudflare scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

_dns-cloudflare - Special case: domain already at Cloudflare Registrar

Communication

  • Detect the user's language from the conversation (the user's own messages, anywhere in the session - not just this invocation: a bare slash command like /bootstrap carries no language signal by itself). If nothing in the conversation gives a signal, fall back to the OS locale (node -e "console.log(Intl.DateTimeFormat().resolvedOptions().locale)") before defaulting to English. ALWAYS reply in that language for every user-facing message: questions, progress, confirmations, summaries, errors - including any example text quoted in this skill, which is illustrative and must be translated, never sent verbatim.
  • Use plain, non-technical business language. Never expose internal script names (*.mjs) or jargon; describe actions in human terms.
  • When generating user-facing content for the scaffolded project (UI labels, emails, copy), write it in the user's language too.
  • Show progress as a short natural-language checklist (in-progress and done states).

You receive as input: <domain>. If the domain's registrar is Cloudflare itself, there is no nameserver to change - Cloudflare already manages the domain's DNS. You just verify that the zone exists and hand control back.

Cloudflare architecture in hypervibe: all DNS operations go through the Cloudflare REST API via curl + the token from the vault (CLOUDFLARE.api_token). No flarectl CLI, no Cloudflare MCP - just curl and the token. wrangler is used separately for Workers / R2 / D1 / KV.

Preamble - token from the vault

CFTOK=$(node "${CLAUDE_SKILL_DIR}/../../scripts/vault/vault.mjs" get CLOUDFLARE api_token); RC=$?

Apply the _get-secret pattern: RC 2/3 -> unlock then retry; RC 4 -> the key is not in the vault, suggest launch.mjs add --name CLOUDFLARE --service Cloudflare --fields "api_token:secret". Never display $CFTOK.

Step 1 - Preflight: is the Cloudflare token valid?

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
