Individual skill
stackblitz-rate-limits
Establish evidence-based WebContainer capacity budgets for boot concurrency, mounted files, dependency installs, processes, previews, memory symptoms, and browser support. Use when a StackBlitz experience is slow, unstable, or being prepared for wider rollout. Trigger with "WebContainer limits", "StackBlitz capacity", or "WebContainer performance budget".

# WebContainer Capacity and Constraints
## Overview
This skill replaces unsupported universal quota tables with measured application budgets. WebContainer capacity depends on the browser, device, project, dependency graph, concurrent embeds, and hosted runtime; the output records local thresholds and graceful degradation rather than claiming a fixed vendor limit.
## Prerequisites
- A named user journey, supported browser/device matrix, and representative synthetic project
- Existing performance or browser-test tooling, or permission to define a measurement plan
- Product thresholds for startup, interaction, failure recovery, and fallback
## Tool Discipline
Use `Read`, `Glob`, and `Grep` to inspect mounted inputs, lockfiles, process creation, embeds, cleanup, and existing performance budgets. Use `WebFetch` only for current official StackBlitz or WebContainers documentation. Use `Write` or `Edit` only for an approved measurement harness or bounded optimization.
