## What it does

The skill runs as a sequence of steps, and each step writes its own file before the next one starts. First the agent gathers context on your application and works out which projects to update, recording them in `AG_UPDATE_SCOPE.md`. Then it collects the full set of changes between your current and target versions into `AG_UPDATE_CHANGES.md`.

Behaviour changes get their own pass. The agent lists them and asks, one by one, whether to accept the new behaviour or restore the old one. Whatever you accept stays in the file as a change to apply, since tests and typechecking may not fail when it is missed.

Migration only works from major version 25 for grid, 8 for charts and 1 for studio. Older versions stop the skill, because it carries no change information going back further. It also compares its own version against `VERSION.md` in the repository: a differing major version means you should run `npx skills update ag-grid/skills` and start again.

Check the current directory for leftover `AG_UPDATE_*.md` files before you run it. The agent will ask whether to start fresh or resume from where those files left off.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ag-grid/skills --skill ag-update -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ag-grid/skills --skill ag-update -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ag-grid/skills --skill ag-update -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ag-grid/skills ag-update
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ag-grid/skills --skill ag-update -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ag-grid/skills --path skills/ag-update
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ag-grid/skills --skill ag-update -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/ag-grid/skills/tree/HEAD/skills/ag-update/SKILL.md

## When to use it
- list the projects and AG Grid dependencies that need updating
- collect the changes between your current and target versions
- decide per behaviour change whether to accept it or restore the old behaviour
- save the migration plan to a file for a fresh agent session
- verify that accepted behaviour changes were actually applied

## Example prompts
- Update AG Grid in this project to the latest version
- Run ag-update and show me which projects can be updated
- Build the change plan for AG Charts into AG_UPDATE_CHANGES.md

## Rules

- Follow the process documented below exactly
- If you are instructed "Tell the user X" then show the message to the user and **continue**.
- If you are instructed "Ask the user X" then show the question to the user and **stop**. Do not continue until you receive a response. If you have a tool available designed to ask the user a question you may use it.
- This skill consists of a set of sequential steps, each of which writes a file with results. Ensure that the file is written before moving on to the next step. DO NOT combine steps, or refer to information in future steps while handling a previous step.

## Explain process to user

Tell the user "Welcome to the AG Update skill. Let's start by gathering some context on your application"

## Version check

- Read `VERSION.md` in this skill folder. Fetch the latest: `https://raw.githubusercontent.com/ag-grid/skills/main/skills/ag-update/VERSION.md`.
- Compare as semver:
  - If the local version is the same as, or newer than, the fetched version: continue silently.
  - If the local version is older and only the patch or minor differs: Prominently tell the user that a new version has been released, show the new and currently installed version, suggest quitting the harness and running `npx skills update ag-grid/skills`. Ask the user if they'd like to continue with this old skill version, suggesting they type "continue" to do so.
  - If the local version is older and the major differs: Prominently tell the user that their current skill version is incompatible and will not work, show the new and currently installed version, tell them to quit the harness and run `npx skills update ag-grid/skills` before resuming. Stop. The skill invocation is now finished. Regardless of the user response, do not follow any of the other instructions in this file.

## Check for existing plan

- Look for files matching `AG_UPDATE_*.md` in the current directory
- If any exist, then ask the user whether they'd like to start fresh and delete these files or resume.
  - If they select start fresh, delete the `AG_UPDATE_*.md` files
  - If they select resume, continue with the skill and skip the stages for which the files have already been generated

## Determine scope

This section populates the AG_UPDATE_SCOPE.md file

1. Determine the full set of potential projects to update. There are instructions in the file `references/determine-scope.md`. If you have access to sub-agents, give that file path to a sub-agent and ask it to report the results to you. Otherwise follow the steps yourself. If this skill was invoked with instructions to upgrade specific projects, pass that to the sub agent.
