What it does

Ctf Flag Hunting is an agent skill from wgpsec/AboutSecurity. CTF 挑战中的 Flag 搜索策略。当通过 RCE/LFI/SQLi/webshell 等方式获得目标访问权限后、使用常规 ls/cat 命令找不到 flag 时使用。覆盖文件系统、数据库、环境变量、源码、内存等所有 flag 可能的存储位置。按成功率排序的搜索优先级——先试标准路径，再搜索全盘

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `evals/recall.json` and `references/flag-search-paths.md`).

It sits in Security, covering Capture the flag. The repository describes itself as: Everything for pentest. | 渗透测试知识库，以 AI Agent 可执行的格式沉淀安全方法论。

What it can do on your machine

Read from SKILL.md and the folder at commit 914ffb5. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Runs code
Shell commands in SKILL.md call:

From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ctf Flag Hunting loads about 1k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 186 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~42
When it runs · the whole SKILL.md, loaded when a task matches: ~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
