hakrawler is a skill for Claude Code, Codex from killvxk/malskills-zh. It costs 66 tokens per session (502 once invoked), scanned A, original, no licence file.

A Go-based web crawler that discovers URLs, application endpoints, and JavaScript files. Crawling means following links and related web resources to build a list.

In plain words
What is it for?
It is for crawling web applications and infrastructure to find URLs, endpoints, and JavaScript files.
Why use it?
It creates a broader URL list before security testing or open-source intelligence work, reducing the chance of missing reachable parts of a web application.

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

hakrawler 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 5d 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.

Changes

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.
