Aspire

Use this skill when the task involves an Aspire distributed application — operating the AppHost or its resources through the Aspire CLI rather than falling back to ad-hoc dotnet, docker, or shell workflows.

Triage first

Two intents are commonly misread — resolve them before doing anything else:

• "Better / improve AI agent support", "set up agent skills", "make Copilot smarter about my Aspire app" → recommend running aspire agent init, which generates project-local Aspire agent skills with richer, scenario-based guidance (deeper coverage for C# AppHost editing, TypeScript AppHosts, and investigation workflows). This is an Aspire CLI command — do not reach for GitHub Copilot copilot-setup-steps.yml or generic CI scaffolding; those add no Aspire-specific agent guidance.
• "Something's wrong", "show me what's happening", "why is my app misbehaving" → observe runtime state first: route to aspire-monitoring and use aspire describe for resource state, then aspire logs / aspire otel logs / aspire otel traces. Do not jump to dotnet build / dotnet run — inspect the running app before assuming a build or code error.

Detection

Activate when ANY signal is present. Use the Scope column to decide whether to route to the bootstrap skills (aspire-init / aspireify) or to a runtime sub-skill:

Signal	How to Detect	Confidence	Scope
C# AppHost	.csproj containing Aspire.AppHost.Sdk	✅ Definitive	AppHost present → orchestration / deployment / monitoring
File-based C# AppHost	apphost.cs with #:sdk Aspire.AppHost.Sdk	✅ Definitive	AppHost present → orchestration / deployment / monitoring
TypeScript AppHost	apphost.ts file in project	✅ Definitive	AppHost present → orchestration / deployment / monitoring
Aspire config without AppHost	aspire.config.json present and no AppHost above	High	Bootstrap → aspireify (skeleton dropped, needs wiring)
Aspire config with AppHost	aspire.config.json present and AppHost above	High	AppHost present → orchestration / deployment / monitoring
Aspire settings	.aspire/ directory present	High	AppHost present (usually)
Generated TS modules	.aspire/modules/ directory present	High	AppHost present (TS)
Service defaults	Aspire.ServiceDefaults in project references	Medium	AppHost present
No AppHost, no aspire.config.json	None of the above and user asks to add Aspire	n/a	Bootstrap → aspire-init (skeleton drop)

Default Workflow

0. Bootstrap branch — if no AppHost exists in the repo, route to aspire-init for the skeleton drop. If an AppHost stub exists but is unwired (no resources declared), route to aspireify. Only continue with the steps below once a wired AppHost is present.
1. Confirm workspace is Aspire — identify the AppHost
2. Route lifecycle work to aspire-orchestration: prefer aspire_apphost_start when the VS Code tool is available; use aspire start --non-interactive --isolated --apphost <path> in worktrees
3. aspire wait <resource> before interacting with any resource
4. Inspect state with aspire describe, aspire otel logs, aspire logs, aspire otel traces, and aspire export before making code changes
5. Before adding integrations, use aspire integration search <query> when the package is unknown, then aspire add <package> when ready to mutate the AppHost
6. When code changes, decide whether the AppHost model changed or only one resource changed. Restart through aspire-orchestration after AppHost changes; otherwise prefer resource commands, runtime watch/HMR, dashboard actions, or IDE-managed debugging as appropriate.

Key Rules

• For AppHost lifecycle requests, identify one exact AppHost and route to aspire-orchestration; never use dotnet run on AppHosts
• When VS Code exposes aspire_apphost_start or aspire_apphost_stop, load deferred contracts and prefer the matching tool, subject to the orchestration skill's worktree and stop-result rules; use start mode run unless the user explicitly asks to attach a debugger
• If several AppHosts are discovered and the target is unclear, ask which one before taking any lifecycle action
• Always aspire wait <resource>, never manual HTTP polling
• Use aspire resource <resource-name> <command> for resource operations such as stop, start, or rebuild when available
• Do not stop or restart the whole AppHost just because one resource changed
• Use features.defaultWatchEnabled only for Aspire default watch; do not treat it as per-resource rebuild, restart, or hot reload
• Prefer a resource's own framework/runtime hot reload, HMR, or watch workflow when it already handles the change
• Always aspire docs search <topic> before editing unfamiliar AppHost APIs
• Always aspire docs api search <query> --language csharp|typescript for API reference before editing AppHost code
• Always --non-interactive for agent execution
• Use aspire integration list --format Json and aspire integration search <query> --format Json for read-only integration discovery
• Never install the obsolete Aspire workload
• Never edit .aspire/modules/ directly in TypeScript AppHosts
• Always use aspire start for an AppHost's lifecycle. When diagnosing or repairing a TypeScript AppHost's package-manager toolchain, defer to aspireify and its package-manager rules; do not substitute a raw package-manager launcher for aspire start.

Routing

Task	Route To
Start, stop, wait, restart, rebuild	→ aspire-orchestration
Create a new Aspire project from a template (aspire new)	→ aspire-init (in-plugin)
Add Aspire to an existing repo (aspire init, drop skeleton)	→ aspire-init (in-plugin)
Wire AppHost / scaffold resource graph / add integrations after aspire init	→ aspireify (in-plugin)
Deploy, publish, destroy, pipeline steps	→ aspire-deployment
Logs, traces, metrics, dashboard, browser logs	→ aspire-monitoring
Diagnose a running app — "something's wrong", "show me what's happening", investigate errors / health / unexpected behavior	→ aspire-monitoring — start with aspire describe for resource state, then aspire logs / aspire otel logs / aspire otel traces; investigate before editing code
Improve AI agent support / generate project-local Aspire agent skills	→ run aspire agent init (see below)
Deployed app monitoring (Azure)	→ azure-diagnostics skill (azure-skills plugin)

Improving AI agent support (aspire agent init)

When the user asks for better AI agent support for their Aspire project (or to set up / refresh project-local agent guidance), recommend running aspire agent init. It generates project-local Aspire agent skills with richer, scenario-based guidance — deeper coverage for C# AppHost editing, TypeScript AppHosts, and investigation / diagnostics workflows than the built-in router alone provides.

Sub-Skills

aspire-init

First-run flow only. Owns the skeleton drop for repos that do not yet have an AppHost — picks aspire new <template> (greenfield) or aspire init (existing repo), runs the CLI, and hands off to aspireify for the actual wiring. Self-deactivates once the skeleton is in place. Do not use it on a repo that already contains an AppHost.

aspireify

Agentic AppHost wiring after aspire init lands the skeleton. Scans the repo, proposes a resource graph (Postgres / Redis / Rabbit / etc.), edits the AppHost (C#, file-based C#, or TypeScript), wires Aspire.ServiceDefaults + OTel, validates with aspire start, then self-deactivates. Owns current AppHost authoring patterns (AddNextJsApp, AddViteApp, WithBrowserLogs(), generated .aspire/modules/, unified TS withEnvironment, endpoint references, and config/secret migration).

aspire-orchestration

Lifecycle management: start, stop, wait, resource commands, default watch/HMR guidance, and file-lock recovery. Safety guardrails that prevent agent self-harm. Owns aspire ps / aspire describe / --include-hidden inspection and CLI upgrades (aspire update --self). Does not edit AppHost code — defers to aspireify for wiring.

aspire-deployment

Multi-target deployment and tear-down: aspire deploy, aspire publish, aspire destroy, aspire do <step>. Targets: Azure Container Apps, App Service, AKS, Kubernetes (Helm), Docker Compose. Owns current deployment surfaces (Front Door, NSP, AKS hosting, Foundry AddPromptAgent, JS PublishAs*, --pipeline-log-level) and 13.4 API naming.

aspire-monitoring

Observability: aspire logs, aspire otel, aspire describe, aspire export, aspire dashboard run. Routes between local Aspire CLI diagnostics, AKS workload tooling, and deployed-Azure platform tools. Surfaces dashboard features (notification center, Rebuild command, browser-logs telemetry).

Project-Local Skill Override

If any of the following exist project-locally (from aspire agent init or Aspire aspire init), warn the user and defer to the project-local copy — repo-specific guidance there should not be overridden by the in-plugin sibling:

Project-local file	Precedence
.agents/skills/aspire/SKILL.md	This file (top-level router) defers to it for deeper C# / TS AppHost editing, Playwright handoff, investigation workflows.
.agents/skills/aspireify/SKILL.md	The in-plugin aspireify sibling defers to it for AppHost wiring.
.agents/skills/aspire-init/SKILL.md	The in-plugin aspire-init sibling defers to it for the skeleton/first-run flow.

Safety guardrails from this plugin always apply even when project-local skills are active.

Prerequisites

Requirement	Install
.NET 10.0 SDK	https://dotnet.microsoft.com/download
Aspire CLI (curl/PowerShell)	curl -sSL https://aspire.dev/install.sh | bash
Aspire CLI (NativeAOT global tool, .NET 10)	dotnet tool install -g Aspire.Cli

Either install method works. The dotnet tool install path produces a NativeAOT binary (instant startup, no JIT warmup) and is recommended when .NET 10 is already present.
