What it does

Aspire is an agent skill from SSWConsulting/SSW.VerticalSliceArchitecture. 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…

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `references/agent-workflows.md`, `references/app-commands.md` and `references/csharp-apphosts.md`).

It sits in Testing & QA, covering Browser testing. It works with TypeScript, Playwright, C# and .NET. The repository describes itself as: An enterprise ready solution template for Vertical Slice Architecture. This template is just one way to apply the Vertical Slice Architecture. The licence is MIT.

When your agent uses it

  • The user is working with an Aspire distributed application and needs to operate the AppHost
  • Its resources through the Aspire CLI: start
  • Wait on the app
  • Inspect resources

Example prompts

  • “/aspire”

Requirements

  • Docker

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Confirm that the workspace is an Aspire app and identify the AppHost.
  2. Start the app with aspire start. Use --isolated in git worktrees or whenever shared local state would be risky.
  3. Use aspire wait before interacting with a resource that needs to be healthy.
  4. Inspect state with aspire describe, then use aspire otel logs, aspire logs, aspire otel traces, and aspire export before making code…
  5. Before adding an integration, introducing a custom dashboard/resource command, or using an unfamiliar AppHost API, use aspire docs search…
  6. Re-run aspire start after AppHost changes. In git worktrees, re-run aspire start --isolated instead of switching to aspire run.

What it can do on your machine

Read from SKILL.md and the folder at commit 42e7a70. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • dotnet

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Aspire loads about 2k tokens when it runs, and up to ~7.2k if it reads all its reference files. Until then it costs about 245 tokens; SKILL.md has 942 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~245
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
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.

Aspire Skill

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

Resources are typically defined in an AppHost such as, AppHost.cs, apphost.ts, or AppHost/AppHost.csproj (Program.cs).

Use this skill for

  • Starting, restarting, and stopping AppHosts with aspire start and aspire stop
  • Initializing Aspire in an existing app with aspire init (drops skeleton files; use the aspireify skill to complete wiring)
  • Inspecting resources, logs, traces, and docs
  • Adding integrations with aspire add
  • Recovering missing TypeScript AppHost support files with aspire restore
  • Discovering the correct frontend URL before a Playwright handoff
  • Understanding unfamiliar Aspire AppHost APIs before editing C# or TypeScript AppHosts
  • Managing AppHost secrets and CLI config
  • Publishing and deploying Aspire apps, including single named steps with aspire do
  • Adding custom dashboard or resource commands with docs-backed AppHost patterns

Do not use this skill for

  • Non-Aspire .NET applications
  • Container-only workflows that do not involve an Aspire AppHost
  • Replacing normal build and test commands when the task is just compiling code or running unit tests

Default workflow

  1. Confirm that the workspace is an Aspire app and identify the AppHost.
  2. Start the app with aspire start. Use --isolated in git worktrees or whenever shared local state would be risky.
  3. Use aspire wait <resource> before interacting with a resource that needs to be healthy.
  4. Inspect state with aspire describe, then use aspire otel logs, aspire logs, aspire otel traces, and aspire export before making code changes. Display returned data using the formatting rules in references/monitoring.md.
  5. Before adding an integration, introducing a custom dashboard/resource command, or using an unfamiliar AppHost API, use aspire docs search <topic> and aspire docs get <slug> for workflow guidance, then use aspire docs api search <query> --language csharp|typescript and aspire docs api get <id> when you need the API reference entry itself.
  6. Re-run aspire start after AppHost changes. In git worktrees, re-run aspire start --isolated instead of switching to aspire run.

C# AppHosts

When the AppHost is implemented in C# such as AppHost.cs, apphost.cs, or a Program.cs-based AppHost, use Aspire docs for workflow guidance and Aspire API docs for the reference entry before editing.

  • Use aspire docs search <topic> and aspire docs get <slug> when you need the documented workflow or pattern.
  • Use aspire docs api search <query> --language csharp and aspire docs api get <id> when you need the C# API reference entry for a resource builder, extension method, or member.
  • If the dotnet-inspect skill is available, use it to inspect local C# APIs, overloads, and builder chains when you need help understanding how the API surface is exposed in code.
  • Keep dotnet-inspect scoped to understanding APIs and symbols; use Aspire docs for the documented workflow and recommended pattern.

TypeScript AppHosts

When the AppHost is apphost.ts, the .modules/ folder at the project root contains generated TypeScript modules that expose the Aspire APIs available to the AppHost. Common files include .modules/aspire.ts, base.ts, and transport.ts.

  • Do not edit .modules/ directly.
  • Use aspire add <package> to add integrations and regenerate the available APIs.
  • Inspect .modules/aspire.ts after aspire add to see the refreshed API surface.
  • The local tsconfig.json often includes .modules/**/*.ts in its compilation scope.

Key rules

  • Prefer aspire start over dotnet run for AppHosts. aspire run blocks the terminal and is a poor fit for agent workflows.
  • Re-running aspire start is the restart path. In git worktrees, aspire start --isolated is both the start and restart command. Do not combine aspire stop and aspire run.
  • Use --apphost <path> when the workspace has multiple AppHosts or discovery is ambiguous.
  • Use --format Json when another tool or script needs machine-readable output.
  • Do not guess the integration or command shape for unfamiliar AppHost changes. Use aspire docs search and aspire docs get for the documented pattern, then use aspire docs api search and aspire docs api get when you need the specific reference entry.
  • For unfamiliar C# AppHost APIs, use Aspire API docs as the primary reference and, if available, use dotnet-inspect only to inspect local symbols, overloads, and builder chains.
  • Never install the obsolete Aspire workload.
  • When a TypeScript AppHost uses .modules/, do not edit generated files directly. Use aspire add to regenerate APIs and inspect .modules/aspire.ts afterward.
  • Prefer official docs from aspire.dev.

Common capabilities

  • Use aspire ps when you need to discover running AppHosts before targeting one.
  • Use aspire update when the task is to refresh AppHost package references through the supported CLI workflow.
  • Use aspire doctor as an early diagnostics step when the local Aspire environment looks unhealthy.
  • Use aspire resource, aspire secret, aspire config, aspire publish, aspire deploy, and aspire do when the objective is resource operations, secrets/config management, or deployment.
  • Use aspire restore, aspire cache clear, aspire certs trust, and aspire certs clean when the task is local environment maintenance or recovery.

Playwright CLI

If Playwright CLI is already configured in the environment, use Aspire first to discover the running app and its endpoints, especially when multiple frontends exist. Prefer aspire describe --format Json when the handoff needs to be scriptable or you need to disambiguate which frontend URL Playwright should use, then hand browser testing off to Playwright CLI.
