ctf-automation

ctf-automation is a skill for Claude Code from MateoBogo/CLEAVE. It costs 0 tokens per session (1,517 once invoked), scanned A, original, no licence file.

A coordinator for capture-the-flag (CTF) security challenges. It examines challenge files, identifies likely challenge types and project files, then creates JSON and Markdown instructions for choosing tools.

In plain words
What is it for?
Use it to classify CTF binaries and project files, detect cryptography, forensics, web, or AI-related material, and prepare dispatch notes for further analysis.
Why use it?
It reduces the manual work of sorting unfamiliar challenge files and deciding which analysis workflow to use. It can also connect triage with a CTFd competition server for syncing and submissions.

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

ctf-automation 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 8d ago.

The scan reads SKILL.md. This mod also ships 12 executable files (aiprobe.py, coordinator.py, cryptosetup.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
