Web server vulnerability scanner for identifying security issues, misconfigurations, and outdated software versions.

  • Works in 6 steps: Authorization Verification → Basic Scanning → Advanced Scanning Options → …
  • Conducting authorized web server security assessments
  • SKILL.md covers Overview, Quick Start, Core Workflow and Security Considerations, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Webapp Nikto is an agent skill from AgentSecOps/SecOpsAgentKit. Web server vulnerability scanner for identifying security issues, misconfigurations, and outdated software versions. Use when: (1) Conducting authorized web server security assessments, (2) Identifying common web vulnerabilities and misconfigurations, (3) Detecting outdated server software and known vulnerabilities, (4) Performing compliance scans for web server hardening, (5) Enumerating web server information and enabled features, (6) Validating security controls and patch levels.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files and assets (for example `assets/ci-config-template.yml`, `assets/rule-template.yaml` and `references/EXAMPLE.md`).

It sits in Security, covering Security review, Vulnerability scanning and Web application vulnerabilities. The repository describes itself as: Security operations toolkit for AI coding agents. Give Claude Code 25+ skills to catch vulnerabilities, scan containers, detect secrets, and enforce policies automatically.

When your agent uses it

  • Conducting authorized web server security assessments
  • Identifying common web vulnerabilities and misconfigurations
  • Detecting outdated server software and known vulnerabilities
  • Performing compliance scans for web server hardening

Example prompts

  • “/webapp-nikto”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Authorization Verification
  2. Basic Scanning
  3. Advanced Scanning Options
  4. Output and Reporting
  5. Performance Tuning
  6. Evasion and Stealth

What it can do on your machine

Read from SKILL.md and the folder at commit 6e25a4b. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    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):

    • cirt.net
    • github.com
    • owasp.org
    • csrc.nist.gov
    • cisecurity.org

    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

Webapp Nikto loads about 2.8k tokens when it runs, and up to ~8.8k if it reads all its reference files. Until then it costs about 125 tokens; SKILL.md has 663 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~125
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.8k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 663 words (~2,812 tokens).

“Nikto is an open-source web server scanner that performs comprehensive tests against web servers for multiple security issues including dangerous files, outdated software versions, and server misconfigurations. This skill covers authorized security assessments of web servers and applications.”
