  • Calls dotnet

What it does

Aspire Restart is an agent skill from platformplatform/PlatformPlatform. Start or restart the .NET Aspire AppHost via the developer CLI. Always use this, never the developer CLI's run command, aspire run, or aspire restart.

Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with .NET. The repository describes itself as: A platform designed for building enterprise-grade, multi-tenant products using Azure, .NET, React, TypeScript, Infrastructure as Code, etc. The licence is MIT.

Example prompts

  • “/aspire-restart”

What it can do on your machine

Read from SKILL.md and the folder at commit 269de1c. 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 Restart loads about 415 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 212 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~415

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
Start or restart the .NET Aspire AppHost via the developer CLI. Always use this, never the developer CLI's `run` command, `aspire run`, or `aspire restart`.

Restart Aspire

bash
dotnet run --project developer-cli -- restart

Use developer-cli exactly as written - do not expand to an absolute worktree path.

Stops any running Aspire AppHost and starts a fresh instance. Detached by default - the CLI returns immediately while Aspire keeps running.

Always use restart, even when nothing is running yet. It is a no-op when Aspire is not up, and the safe default in every other case. Never use the developer CLI's run command, aspire run, or aspire restart.

  • --public-url <url> - set PUBLIC_URL (e.g. an ngrok URL)

When to use

  • After backend or frontend changes - restart is the safe default; it works whether Aspire is up or not.
  • To run database migrations.
  • When hot reload breaks or stops picking up changes.
  • Before running e2e tests on a fresh stack.

Port allocation

Fully automatic. On a fresh checkout the developer CLI bootstraps .workspace/port.txt: the root gets the default base port; worktrees scan a fixed list of candidates and pick the first one whose ports are all free. Once written, the file is the authoritative allocation for the lifetime of the checkout.

Output is fire-and-forget

The CLI prints Aspire is restarting on https://app.dev.localhost:<port> and exits before Aspire is fully ready.

Stopping Aspire

To stop without restarting, run dotnet run --project developer-cli -- stop. Rarely needed - prefer restart for everyday use.
