pentest-toolkit-pro-html — Claude Code skill

A skill that tells the agent how to drive an offline pentest toolkit: OWASP WSTG checklists, finding tracking, CVSS scoring and a printable report. Handy when results must live in one file.

What pentest-toolkit-pro-html does

The toolkit itself is a single HTML file you open in a browser. No build step, no dependencies. Its tabs cover rules of engagement, contract templates, mission timeline, the OWASP WSTG checklist, a findings database, a CVSS calculator, a remediation plan, report output, plus web and infrastructure cheat sheets. The skill gives the agent the map of those tabs.

Records live in browser localStorage under keys such as pentestToolkit_owaspChecklist and pentestToolkit_vulnerabilities. That keeps everything local and works without a network. It also means the data belongs to one browser profile — move it by moving the profile, and an agent in another window won't see your entries.

From the skill the agent learns how to wire a new panel through data-tab, how to extend the WSTG list with your own tests, and how to push a finding template with severity, cvss, impact and remediation fields. No API key, no server: open the file and start.

What it helps with

  • run a web app through the OWASP WSTG checklist without losing track of progress
  • score a finding with CVSS while the test is still running
  • keep findings in a database with impact and fix notes
  • produce a printable report at the end of an engagement
  • extend the toolkit with a custom test or panel

Example prompts for the agent

  • Open the pentesting toolkit web interface and list the OWASP WSTG items I haven't checked yet
  • Add this finding to the vulnerability tracker and work out its CVSS score
  • Generate a pentest report from what's currently saved in the toolkit
