lookup-abuseipdb is a skill for Claude Code, Codex from Liberty91LTD/cti-skills. It costs 49 tokens per session (1,100 once invoked), scanned A, original, MIT.

A retrieval tool for checking whether an IPv4 or IPv6 address has been reported for abuse on AbuseIPDB, including its confidence score and report history.

In plain words
What is it for?
It helps investigate suspicious IP addresses, review recent abuse reports, inspect individual reports, and check IP blocks or blacklists.
Why use it?
It gathers community-reported information about an IP address without requiring manual website checks or interpretation during retrieval.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node tools/clis/abuseipdb.js ip <ip>.

Good fit It helps investigate suspicious IP addresses, review recent abuse reports, inspect individual reports, and check IP blocks or blacklists.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

lookup-abuseipdb scanned grade A with 0 findings 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

lookup-abuseipdb

Queries AbuseIPDB for IP reputation data. IP addresses only (v4 and v6). Retrieval only — do not interpret.

When to invoke

  • User asks about abuse reports for an IP
  • Investigation skill needs community-reported abuse context
  • Triaging whether an IP has a history of malicious behavior

How to invoke

Two CLIs are provided. Pick by capability needed:

Basic check — Node CLI (zero deps)

node tools/clis/abuseipdb.js ip <ip>

Hits the /check endpoint with a 90-day window. Best for fast retrieval inside an investigation chain.

Full read-only suite — Python CLI (stdlib only)

python3 tools/clis/abuseipdb.py check <ip> [--max-age-in-days N] [--verbose]
python3 tools/clis/abuseipdb.py reports <ip> [--per-page N] [--page N]
python3 tools/clis/abuseipdb.py check-block <cidr> [--max-age-in-days N]
python3 tools/clis/abuseipdb.py blacklist [--confidence-min N] [--limit N]
                                          [--ip-version 4|6]
                                          [--only-countries CC,CC]
                                          [--except-country CC,CC]

No external deps — Python 3 stdlib only, no venv needed.

Capabilities the Node CLI doesn't have:

  • Verbose check (check --verbose) — full per-report list including category, comment, reporter ID, country.
  • Reports endpoint — paginated raw report history (uses zero check-quota).
  • CIDR-block check (check-block) — reputation summary across an entire network range. Useful for triaging suspicious /24s, hosting providers, ASN sub-ranges.
  • Blacklist download — bulk pull of high-confidence abuse IPs filtered by country / IP version / confidence threshold. Useful for ingesting into block lists.

Examples:

# Detailed report list for a suspect IP
python3 tools/clis/abuseipdb.py check 185.220.101.45 --verbose

# What's been reported in this /24 in the last 30 days?
python3 tools/clis/abuseipdb.py check-block 185.220.101.0/24

# Pull RU-only IPs with 90%+ confidence, max 500
python3 tools/clis/abuseipdb.py blacklist --only-countries RU --confidence-min 90 --limit 500

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.
