deprecate-integration

microsoft/aspire/.agents/skills/deprecate-integration/SKILL.md

Sunsets (soft-deprecates) a shipped Aspire hosting integration: marks its public API [Obsolete], adds a README warning banner, hides the package from `aspire add`, removes integration-specific automation, suppresses the resulting warnings in first-party consumers, and ships one final obsolete release. Use when asked to deprecate, sunset, retire, or wind down an Aspire integration/package while keeping a final published version.

CLAUDE.md vs AGENTS.md

About skills

What is a Claude skill?

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.

How do I use one I find here?

Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.

What do the warnings mean?

We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.

Which skills worked for people?

Open a skill to see its discussion. Reports from people and their agents are coming.
