# provider-upgrade

Walks an agent through bumping a Pulumi provider version and reconciling preview diffs so nothing gets recreated in the cloud.

## What it does

The skill runs a loop: bump the provider dependency, run a preview, sort every resource that isn't `same` into categories, then fix what broke. The framing is that a provider upgrade is a translation, not a change request. Your infrastructure intent stays put; only the API that expresses it moves. A correct translation shows zero diff.

After each preview comes the diff checkpoint. A resource you edited should still read `same` — if it reads `update`, your rename or restructure changed meaning, not just syntax. A new resource block showing `create` usually means the cloud object already exists and needs an import, not a fresh build. A removed block showing `delete` is real destruction through the provider API, so the path is `pulumi state delete '<urn>'` first, then import the replacement.

It covers all providers, aws, azure-native, gcp, kubernetes, aws-native, cloudflare and datadog among them. Cross-stack audits of which package versions are in use are out of scope — that's the `package-usage` skill. Worth installing if a past SDK bump handed you unexpected replacements.

## Requirements
- Works with: AWS, Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pulumi/agent-skills --skill provider-upgrade -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/provider-upgrade/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/provider-upgrade/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pulumi/agent-skills --skill provider-upgrade -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/provider-upgrade/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pulumi/agent-skills --skill provider-upgrade -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/provider-upgrade/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pulumi/agent-skills provider-upgrade
```

2. **Manually: put the files in place**
- File: `.github/skills/provider-upgrade/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add pulumi/agent-skills --skill provider-upgrade -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pulumi/agent-skills --path pulumi/skills/provider-upgrade
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/provider-upgrade/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add pulumi/agent-skills --skill provider-upgrade -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/pulumi/agent-skills/tree/HEAD/pulumi/skills/provider-upgrade/SKILL.md

## When to use it
- bump a Pulumi provider version without breaking the stack
- find out why a resource flipped to `update` after a property rename
- swap a `create` for an import of an existing cloud object
- tell real resource destruction apart from state cleanup
- fix pulumi-gcp v10 errors such as a missing `gcp.notebooks` type

## Example prompts
- upgrade the aws provider to the latest version and show me what changes in the preview
- after the gcp upgrade a resource wants to replace — figure out why
- the preview shows a create for something already in the cloud, help me import it

description: >
  Upgrade any Pulumi provider to a newer version and reconcile the resulting diff. Use when
  users want to upgrade or update a provider (including editing package.json, requirements.txt,
  pyproject.toml, go.mod, or Pulumi.yaml to bump a provider SDK), check for breaking changes
  before or during an upgrade, fix resources that broke after a provider upgrade, or resolve
  unexpected replacements, creates, or deletes in a post-upgrade preview, including
  pulumi-gcp v10 errors such as a missing gcp.notebooks or gcp.iap.Brand type or a required
  secretDataWoVersion. Applies to all
  providers (aws, azure-native, gcp, kubernetes, aws-native, cloudflare, datadog, etc.) — not
  just Tier 1. Do NOT use for querying which stacks use what package versions; use skill
  `package-usage` for cross-stack audits. Do NOT use for general infrastructure tasks.

# Upgrading Pulumi Providers

## The Principle

A provider upgrade is a translation, not a change request.

The user's infrastructure intent hasn't changed - they still want the same bucket, the
same function, the same cluster. What changed is how the provider's API expresses that
intent. Your job is to translate their existing code into the new API so that Pulumi sees
no difference between what the code says and what already exists.

There are four layers to keep in mind:

1. **User intent** - what the user wants in the cloud (unchanged during an upgrade)
2. **Code** - how the program expresses that intent using the provider API (may need updating)
3. **Pulumi state** - Pulumi's stored representation of what exists (may need reconciliation)
4. **Real cloud** - the actual infrastructure (should not change during an upgrade)

During an upgrade, layers 2 and 3 may need to change so that they continue to correctly
represent the unchanged layers 1 and 4.

A correct translation produces zero diff. The Pulumi engine doesn't have a concept of
"upgrade" - it just compares goal state (your code) against actual state (the state file)
and reconciles. If the translation is correct, those two states match and nothing happens.
If you see a diff, either your translation is wrong, or something beyond a code change is
needed (import, alias, manual step). In all cases, the diff is a problem to solve, not a
consequence to accept.
