Eriklieben Agentic Dev Workflow Aspire

version: 1.0.0 name: aspire description: "Orchestrates Aspire distributed applications using the Aspire CLI for running, debugging, and managing distributed apps. USE FOR: aspire start, aspire stop, start aspire app, aspire describe, list aspire integrations, debug aspire issues, view aspire logs, add aspire resource, aspire dashboard, update aspire apphost. DO NOT USE FOR: non-Aspire .NET apps (use dotnet CLI), container-only deployments (use docker/podman), Azure deployment after local testing (use azure-deploy skill). INVOKES: Aspire CLI commands (aspire start, aspire describe, aspire otel logs, aspire docs search, aspire add), bash. FOR SINGLE OPERATIONS: Use Aspire CLI commands directly for quick resource status or doc lookups."

Aspire Skill

This repository uses Aspire to orchestrate its distributed application. Resources are defined in the AppHost project (apphost.cs or apphost.ts).

CLI command reference

Most commands support --format Json for machine-readable output. Use --apphost <path> to target a specific AppHost.

Important: Use ~/.dotnet/tools/aspire explicitly — Aspire 13.1.1 at ~/.aspire/bin/aspire may shadow the 13.2 version on PATH.

Key workflows

Running in agent environments

Use aspire start to run the AppHost in the background. When working in a git worktree, use --isolated to avoid port conflicts and to prevent sharing user secrets or other local state with other running instances:

~/.dotnet/tools/aspire start --isolated

Use aspire wait <resource> to block until a resource is healthy before interacting with it:

~/.dotnet/tools/aspire start --isolated
~/.dotnet/tools/aspire wait myapi

Relaunching is safe — aspire start automatically stops any previous instance. Re-run aspire start whenever changes are made to the AppHost project.

Debugging issues

Before making code changes, inspect the app state:

1. ~/.dotnet/tools/aspire describe — check resource status
2. ~/.dotnet/tools/aspire otel logs <resource> — view structured logs
3. ~/.dotnet/tools/aspire logs <resource> — view console output
4. ~/.dotnet/tools/aspire otel traces <resource> — view distributed traces

Adding integrations

Use aspire docs search to find integration documentation, then aspire docs get to read the full guide. Use aspire add to add the integration package to the AppHost.

After adding an integration, restart the app with aspire start for the new resource to take effect.

Using resource MCP tools

Some resources expose MCP tools (e.g. WithPostgresMcp() adds SQL query tools). Discover and call them via CLI:

~/.dotnet/tools/aspire mcp tools
~/.dotnet/tools/aspire mcp tools --format Json
~/.dotnet/tools/aspire mcp call <resource> <tool> --input '{"key":"value"}'

Important rules

• Always start the app first (aspire start) before making changes to verify the starting state.
• To restart, just run aspire start again — it automatically stops the previous instance. NEVER use aspire stop then aspire run. NEVER use aspire run at all.
• Use --isolated when working in a worktree.
• Avoid persistent containers early in development to prevent state management issues.
• Never install the Aspire workload — it is obsolete.
• Prefer aspire.dev and learn.microsoft.com/microsoft/aspire for official documentation.

Playwright CLI

If configured, use Playwright CLI for functional testing of resources. Get endpoints via aspire describe. Run playwright-cli --help for available commands.
