A command guide for managing Domain Name System records, which connect website names such as example.com to internet services.

Use it to inspect a domain's DNS records, create or remove records, export them, and safely pass record names, zones, and values to the command-line tool.

It provides the right actions for listing, adding, deleting, or exporting records while requiring unsafe input to be rejected before running commands.

dns — Command for Claude Code by ThrownLemon/claude-code-plugins

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/ThrownLemon/claude-code-plugins

Made for: Claude Code.

Or install cloudflare, the plugin that ships this one along with the rest of its 1 skill, 6 commands, 1 agent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00011	$0.00878
Opus 5.5	$0.00004	$0.00351
Sonnet 5.5	$0.00002	$0.00176
Haiku 4.5	$0.00001	$0.00088

Security

Grade C, and why

dns scanned grade C 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 1mo 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

What it actually says

Input Safety — apply before any Bash invocation

Treat every $ARGUMENTS.* value as untrusted input. Before passing any value to the Bash tool:

Reject dangerous tokens. If a value contains $(, backticks, ;, |, &, >, <, or starts with - (could be mistaken for a flag), refuse and ask the user to rephrase. Double-quoting does NOT block command substitution — "$(rm -rf /)" still executes inside double quotes.
Prefer the Bash tool's argv contract over constructed shell strings. When you must use a shell string, single-quote the value and escape embedded single quotes ('\''), or build the command via printf %q.
Any "$ARGUMENTS.foo" patterns shown below are illustrative. Sanitize the value first; never blindly substitute.

You are managing Cloudflare DNS records using the cf CLI. Based on the provided arguments, execute the appropriate command.

Quote every user-supplied value when shelling out (e.g. "$ARGUMENTS.zone"). Unquoted values would let shell metacharacters in zone names, record names, or content execute. This applies to every cf call below.

For action=list:

If $ARGUMENTS.zone is provided, run cf dns list "$ARGUMENTS.zone" --json
Display the results in a readable table format
If no zone provided, first list zones with cf zones list --json and ask which one to query

For action=add:

Verify required parameters: zone, record-type, name, content
Build the command (quote every value): cf dns create "$ARGUMENTS.zone" --type "$ARGUMENTS.record-type" --name "$ARGUMENTS.name" --content "$ARGUMENTS.content" --json
Proxied behavior: the default is true. If $ARGUMENTS.proxied is omitted or equals "true", append --proxied. If it explicitly equals "false", omit the flag.
If $ARGUMENTS.ttl is provided, append --ttl "$ARGUMENTS.ttl"
Display the created record details

For action=delete:

Verify required parameters: zone, record-id
ALWAYS confirm with the user before deleting: "Are you sure you want to delete DNS record $ARGUMENTS.record-id from zone $ARGUMENTS.zone? (yes/no)"
Only proceed if user confirms with "yes" or "y"
Run cf dns delete "$ARGUMENTS.zone" "$ARGUMENTS.record-id" --json
Display deletion confirmation

For action=export:

Verify $ARGUMENTS.zone is provided
Run cf dns export "$ARGUMENTS.zone"
Display the bind-format output

If any required parameters are missing for the specified action, prompt the user to provide them.

What this file has done since we first saw it

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.

dns is a command published in the GitHub repository ThrownLemon/claude-code-plugins (2 stars, last pushed 4mo ago), licensed MIT. It adds 11 tokens to every session and 878 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
