SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audits applications for runtime stability, resilience, and attack-surface weaknesses to prevent incidents like runaway logs, memory bloat, unbounded resources, crash loops, and DoS exposure.

Core Features & Use Cases

  • Phase 1 — Profile the application: classify its deployment profile and scope for targeted hardening.
  • Phase 2 — Run the audit: apply seven-category hardening across the entire app or a user-specified feature/path.
  • Phase 3 — Report and guidance: generate a structured findings report with prioritized fixes and rationale for production-readiness.

Quick Start

Provide the application scope and run the hardening audit to generate a findings report.

Frequently Asked Questions about app-harden

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I audit my application for runtime stability and security weaknesses?

To audit application runtime stability and security, this Skill profiles your deployment scope and applies a seven-category hardening process to enforce resource bounds, timeouts, and input validation. It generates a structured findings report with prioritized fixes.

What causes memory bloat and crash loops in production applications?

Memory bloat and crash loops in production applications stem from unbounded resources, runaway logs, and failure handling gaps. This Skill audits your app to identify these specific attack-surface weaknesses and runtime stability risks before they cause incidents.

Can I run a security and resilience audit on just one feature path?

Yes, you can run security and resilience audits on a user-specified feature path. The Skill profiles your application deployment scope in Phase 1, then applies targeted hardening checks across that specific path or the whole app.

How do I prevent DoS vectors and unbounded resource consumption in my app?

To prevent DoS vectors and unbounded resource consumption, this Skill enforces resource bounds and timeouts during its hardening audit. It checks failure handling and attack-surface reduction to ensure your application remains resilient under runtime stress.

Does the hardening audit cover secrets hygiene and supply-chain checks?

Yes, the hardening audit covers secrets hygiene and supply-chain checks. It applies a seven-category assessment framework that includes failure handling, input validation, and attack-surface reduction to evaluate overall production-readiness.

What is the best way to prepare an application for production-readiness?

The best way to prepare an application for production-readiness is to run a structured hardening audit. This Skill profiles your app, enforces resource bounds and timeouts, validates inputs, and generates a prioritized findings report with rationale for fixes.
