Stop shipping AI-generated vulnerabilities. AI Code Security Sentinel is a dual-engine security system engineered for developers building with Cursor, Claude Code, and Antigravity. It pairs a portable multi-client agent skill that prevents vulnerable patterns at prompt-time with a zero-dependency, 100% offline Node.js CLI scanner that intercepts secret leaks, prompt injections, and OWASP flaws in under 2 seconds before commits or pull requests.
A dual-engine security suite combining a prompt-time AI agent skill and a zero-dependency offline CLI scanner to detect secrets, OWASP LLM vulnerabilities, and classical injection vectors.
Solo developers, AI engineers, indie hackers, and software development agencies building with Cursor, Claude Code, or Antigravity.
Dual-engine enforcement: prompt-time AST and schema interception via portable SKILL.md plus deterministic regex and structural code analysis in scripts/scan.mjs running 100% offline.
Scans codebases and diffs in under 2 seconds across 30+ production rules, blocking critical leaks before commits reach GitHub with zero cloud telemetry.
Why this architecture wins
Swipe to compare ↔| Without this skill (Manual & Flawed) | With this skill (Deterministic & Gated) |
|---|---|
| Without this skill ✕ Cursor or Claude Code pastes a live Stripe or OpenAI API key into a test file, which gets committed to a public repo and drained within 90 seconds. | With this skill ✓ Local pre-commit hook scans your git diff in 80ms, halts the commit, and displays the exact line with a drop-in safe environment variable patch. |
| Without this skill ✕ Concatenating untrusted user inputs directly into AI agent prompts, leaving your application wide open to prompt injection (OWASP LLM01) and tool RCE. | With this skill ✓ Prompt-time agent instructions automatically enforce XML boundary delimiters and strict Zod schema validation across all agent tools. |
| Without this skill ✕ Paying $99–$499/month per seat for enterprise scanners that slow your build to a crawl and upload proprietary source code to external servers. | With this skill ✓ One-time ₹1,999 / $69 lifetime ownership with 100% offline execution, zero dependencies, zero network requests, and zero telemetry. |

Before you buy
Will it work with my stack?
It ships as ZIP · Skill + Local Node Scanner and is built with Node.js, OWASP Top 10 for LLMs, AI Agent Skills, JavaScript, TypeScript, Git Hooks, Claude Code, Cursor. You run it in your own workspace — there is no hosted account or platform lock-in on my side.
Is this a subscription?
No. It is a one-time payment. Lifetime free updates and a commercial license are included.
How fast do I get the files?
Immediately after payment. Razorpay confirms the order and the download link appears on the confirmation screen and in your receipt email.
What if it does not fit my workflow?
Email the order number within 30 days for a refund — no form to fill in.
Questions
Does the scanner send my code or API keys to any cloud servers?
No. AI Code Security Sentinel is 100% offline. It makes zero network calls, requires zero external npm packages, and has zero telemetry. Your code and secrets never leave your local machine.
How is this different from Snyk, SonarQube, or TruffleHog?
Snyk and SonarQube cost $99–$499/seat/month, take minutes to run in the cloud, and lack specific rules for AI prompt injection (OWASP LLM01), tool SSRF, or AI package hallucinations. TruffleHog only checks secrets. Sentinel provides both prompt-time AI guidance and an instant (<2s) offline local scanner for both secrets and AI-specific vulnerabilities.
Does it require npm install or node_modules?
No. The scanner is written in pure vanilla Node.js using standard ES modules. It runs instantly on any machine with Node.js 18+ installed with zero npm installs.
Which AI assistants and IDEs are supported?
The SKILL.md agent works natively in Anthropic Claude Code, Cursor IDE, Google Antigravity, Windsurf, and OpenAI Codex CLI. The CLI scanner works across any editor, terminal, or CI/CD runner on macOS, Linux, and Windows WSL.
Can I use this for client deliverables?
Yes. The commercial license includes rights to use the scanner and agent across client projects and produce white-label Markdown audit reports to prove your deliverables are secure.
Is the ₹1,999 price GST inclusive?
Yes. The ₹1,999 price is GST-inclusive with instant UPI QR checkout (PhonePe, Google Pay, Paytm, CRED) and automated GST tax invoices for business expense ITC claims.
