What it does

When this skill is active, the agent treats a long security-testing checklist as its working method. It covers reconnaissance, finding origin servers behind CDNs or WAFs, and testing authentication, sessions, and access control, and it tracks which items are done and suggests next steps. It is a structured guide for security testers, not an automated scanner: the agent reasons through the steps and can suggest commands, but this file itself contains no executable scripts.

Great for

  • Security testers running time-limited or CTF-style web application assessments
  • Developers who want a structured self-review checklist of common authentication and access control weaknesses
  • Anyone planning an initial rapid surface map of an application they are authorised to test

Skip it if

  • Testing systems you do not own or have explicit written permission to assess, because the checklist describes active attack techniques and could be misused or be unlawful
  • Non-technical users looking for a plain security audit report, since the output assumes security knowledge and terms like CSRF, JWT and DPoP
  • Complete or compliance-grade assessments, because the checklist is a fast triage aid and skips depth on many items

Try asking

  • “Use the fast checking checklist to run a quick recon pass on this web app I am authorised to test”
  • “Give me a time-boxed 60-minute checklist for assessing the login and session handling of our staging site”
  • “Walk through the access control section with me and track which items I have completed”
  • “What quick wins should I check first for a CTF web challenge?”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • State the scope and written authorisation up front so the agent keeps its suggestions within the engagement rules
  • Ask the agent to prioritise items for your time budget, since the checklist is long and not all items are quick
  • Run the suggested commands yourself and paste results back, so the agent can track findings and recommend next steps
