SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Assess sandbox host resources (memory, swap, disk, CPU, Docker usage) and readiness to start or build a stack. Ranks reclaim levers by safety×yield, runs the zero-risk ones, and confirms before any destructive removal.

Core Features & Use Cases

  • Snapshot host resources and identify headroom to safely start a stack or perform builds.
  • Provide a Docker resource breakdown and guided reclaim ladder order with explicit user confirmation.
  • Propose non-destructive adjustments first and guide memory reclaim when binding constraints are memory, with clear safety gates.

Quick Start

Run health-check to assess current host resources and confirm readiness for starting or building a stack.

Frequently Asked Questions about health-check

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

FAQPage Schema
How do I check available memory and disk space before starting a Docker build?▼

Run a system health-check to snapshot RAM, swap, disk, and CPU status, which determines safe headroom and readiness before starting or rebuilding your Docker stack.

What is the safest way to free up memory for resource-constrained dev stacks?▼

Use a guided reclaim ladder that ranks reclaim levers by safety and yield, automatically runs zero-risk adjustments first, and requires explicit user confirmation before any destructive removal.

Can I assess Docker resource usage without risking accidental data removal?▼

Yes, you can assess Docker usage safely by generating a Docker resource breakdown and executing only non-destructive adjustments, with safety gates enforcing user confirmation before destructive actions.

How do I triage system resources for a resource-constrained build environment?▼

Triage system resources by assessing host readiness through deterministic steps that report RAM, swap, disk, and CPU status, then applying tier-based reclaim guidance to identify safe headroom.

Does the health-check skill require any dependencies to analyze sandbox host resources?▼

No, the health-check skill requires no external dependencies to analyze sandbox host resources, directly assessing memory, swap, disk, CPU, and Docker usage to determine stack readiness.

When should I run a sandbox health assessment before rebuilding a stack?▼

Run a sandbox health assessment before rebuilding a stack whenever you need to verify host headroom, identify reclaim levers, and ensure resource constraints will not cause build failures.
