What it does

Security Webshells is an agent skill from Eyadkelleh/awesome-skills-security. Web shell samples for detection and analysis: PHP, ASP, ASPX, JSP, Python, Perl shells. Use for security research and detection system testing.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 89 other files, including reference files (for example `references/Web-Shells/FuzzDB/cmd.sh`, `references/Web-Shells/FuzzDB/list.sh` and `references/Web-Shells/FuzzDB/up.sh`).

It sits in Security. It works with PHP and Python. The repository describes itself as: Security testing toolkit for AI Agent: curated SecLists wordlists, injection payloads, and expert agents for authorized pentesting, CTFs, and bug bounties.

When your agent uses it

  • Security research and detection system testing

Example prompts

  • “/security-webshells”

Requirements

  • Python 3
  • A Bash shell

What it can do on your machine

Read from SKILL.md and the folder at commit ae26985. 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.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (PHP and Shell, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • php
    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    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

Security Webshells loads about 636 tokens when it runs, and up to ~60k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 197 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~636
With references · SKILL.md plus every file in references/, read only if the agent opens them
~60k

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.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 197 words (~636 tokens).
