What it does

Hosting Integration Authoring is an agent skill from microsoft/aspire, published by the product's own GitHub organization. Guides authoring and reviewing Aspire.Hosting integration APIs. Classifies integration archetypes, then applies self-contained best practices for naming, resource shape, run/publish/deploy behavior, eventing, connection properties, security, endpoint semantics, polyglot exports, READMEs, and tests.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 32 other files (for example `resources/api-naming-and-shape.md`, `resources/app-model-fundamentals.md` and `resources/archetype-admin-and-tool-container.md`).

It sits in Development, covering Technical documentation. The repository describes itself as: Aspire is the tool for code-first, extensible, observable dev and deploy. The licence is MIT.

When your agent uses it

  • Tasks that involve Technical documentation

Example prompts

  • “Use the hosting-integration-authoring skill to guide authoring and reviewing Aspire.Hosting integration APIs”
  • “/hosting-integration-authoring”

Requirements

  • Docker

Workflow steps

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

  1. Resource shape.
  2. Lifecycle mode.
  3. Integration role.
  4. Structure.

What it can do on your machine

Read from SKILL.md and the folder at commit 809a672. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Hosting Integration Authoring loads about 1.6k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 556 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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.

Guides authoring and reviewing Aspire.Hosting integration APIs. Classifies integration archetypes, then applies self-contained best practices for naming, resource shape, run/publish/deploy behavior, eventing, connection properties, security, endpoint semantics, polyglot exports, READMEs, and tests.

Aspire hosting integration authoring

Use this skill when creating, modifying, or reviewing Aspire.Hosting.* integration APIs.

This skill is self-contained. The resource files in this skill are the authoritative guidance, and repository paths are examples of existing patterns only.

First step: classify the integration

Read resources/selector-matrix.md first. Then read resources/app-model-fundamentals.md for the app model rules that apply to every hosting integration. Classify the work across all four axes:

  1. Resource shape.
  2. Lifecycle mode.
  3. Integration role.
  4. Structure.

Do not force the integration into a single bucket. Most integrations compose several patterns. For example, PostgreSQL is a container-backed service, has parent-child database resources, exposes connection properties, creates databases during resource readiness, and has admin UI companion helpers.

Then read the matching resources

Always read the relevant archetype resource and the cross-cutting resources that apply to the change.

Authoring workflow

  1. State the classification briefly before changing or reviewing code.
  2. Apply the archetype-specific DO/DON'T list.
  3. Apply every relevant cross-cutting checklist.
  4. Validate both run-mode and publish/deploy behavior when the integration changes those surfaces.
  5. Keep generated API baseline files under */api/*.cs untouched unless the task explicitly asks for API baseline regeneration.

Review workflow

When reviewing an integration PR, look for concrete violations that can cause wrong runtime behavior, wrong generated manifests, broken deployment output, bad public API, missing connection properties, or bad polyglot projection. Do not spend review budget on style-only comments.
