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.
