Aspire Startup Performance Measurement
This skill provides patterns and practices for measuring .NET Aspire application startup performance using the Measure-StartupPerformance.ps1 (Windows/PowerShell) or measure-startup-performance.sh (macOS/Linux) script and the companion TraceAnalyzer tool.
Overview
The startup performance tooling collects dotnet-trace traces from an Aspire AppHost application and computes the startup duration from AspireEventSource events. Specifically, it measures the time between the DcpModelCreationStart (event ID 17) and DcpModelCreationStop (event ID 18) events emitted by the Microsoft-Aspire-Hosting EventSource provider.
PowerShell Script (Windows): tools/perf/Measure-StartupPerformance.ps1
Bash Script (macOS/Linux): tools/perf/measure-startup-performance.sh
TraceAnalyzer Location: tools/perf/TraceAnalyzer/

Prerequisites

aspire
Use this skill when the user is working with an Aspire distributed application and needs to operate the AppHost or its resources through the Aspire CLI: start, restart, stop, or wait on the app; inspect resources, logs, traces, docs, or health; add integrations; manage secrets or config; publish, deploy, or rerun a named pipeline step; initialize Aspire in an existing app; recover missing `.modules` files in a TypeScript AppHost; discover the right frontend URL for Playwright from Aspire state; expose custom dashboard/resource commands; or understand unfamiliar Aspire AppHost APIs in C# or TypeScript. Use it even if they describe the task in terms of an AppHost, resources, dashboard, existing app bootstrap, missing generated modules, Playwright URL discovery, C# API understanding, or local distributed app workflow without explicitly naming Aspire. Do not use it for non-Aspire .NET apps, container-only repos with no AppHost, or ordinary build and test tasks.
4aspireify
One-time skill for completing Aspire initialization in an existing app after `aspire init` has dropped the skeleton AppHost. Use this skill when an `aspire.config.json` exists but the AppHost has not yet been wired up.
2hex1b
CLI tool for automating any terminal application — TUI apps, shells, CLI tools, REPLs, and more. Use when you need to launch a process in a virtual terminal, capture its screen output, inject keystrokes or mouse input, take screenshots, record sessions, or assert on what's visible.
1api-review
Reviews .NET API surface area PRs for design guideline violations. Analyzes api/*.cs file diffs, applies review rules from .NET Framework Design Guidelines and Aspire conventions, and attributes findings to the developer who introduced each API (via git blame). Use this when asked to review API surface area changes.
1create-pr
Create a pull request using the repository PR template. Use when asked to: create PR, open PR, push and create PR, submit PR, open pull request, send changes for review.
1pr-testing
Downloads and tests Aspire CLI from a PR build, preferably in the repo-local container runner under eng/scripts, verifies version, and runs test scenarios based on PR changes. Use this when asked to test a pull request.
