vapt

vapt is a skill for Claude Code from bhuvangupta/vapt-claude. It costs 60 tokens per session (2,482 once invoked), scanned A, original, MIT.

A web application security testing workflow that checks an authorised website for weaknesses. It covers areas such as network exposure, encryption, login and sessions, permissions, APIs, headers, business rules, and GraphQL.

In plain words
What is it for?
Use it to assess a web application, API, or GraphQL service and produce findings about vulnerabilities and security gaps. It offers focused checks as well as a full assessment.
Why use it?
It brings reconnaissance, security scans, attack simulations, and report writing into one process instead of requiring separate checks. An authorisation gate helps ensure active testing is approved first.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vapt scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
