## What it does

This skill guides the migration of an existing subgraph from The Graph to Goldsky as a drop-in replacement. You do not have to modify your subgraph code. The workflow supports three input paths: a running public GraphQL endpoint via `--from-url`, an IPFS deployment identifier via `--from-ipfs-hash`, or local source code with `--path`.

Running the migration requires the Goldsky CLI logged in via `goldsky login`. Windows setups rely on WSL. Once deployed through `goldsky subgraph deploy`, the skill helps verify sync progress using GraphQL `_meta` queries and pins a permanent alias with `goldsky subgraph tag create`. Subgraphs matching an already indexed IPFS hash may sync to 100% instantly.

The instructions strictly forbid guessing endpoint URLs and giving pricing estimates. When deployments fail due to multiple `apiVersion` values or network slug mismatches, the workflow hands off diagnostics to `/subgraph-doctor`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill subgraph-migrate -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill subgraph-migrate -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill subgraph-migrate -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install goldsky-io/goldsky-agent subgraph-migrate
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill subgraph-migrate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/goldsky-io/goldsky-agent --path skills/subgraph-migrate
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill subgraph-migrate -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/goldsky-io/goldsky-agent/tree/HEAD/skills/subgraph-migrate/SKILL.md

## When to use it
- Migrate an active subgraph to Goldsky without modifying handler code
- Deploy a subgraph using an IPFS hash or an existing GraphQL endpoint
- Assign a permanent release tag to keep frontend endpoint URLs stable
- Monitor block indexing progress through `_meta` GraphQL queries

## Example prompts
- Migrate my subgraph from The Graph to Goldsky using its IPFS hash
- Deploy a drop-in replacement subgraph to Goldsky from my existing GraphQL URL
- Switch our dApp subgraph endpoint from The Graph hosted service to Goldsky

description: "Migrate a subgraph from The Graph to Goldsky as a drop-in replacement — no code changes required. Use this skill when the user wants to move, switch, port, or migrate a subgraph off The Graph (hosted service, Subgraph Studio, or the decentralized network) onto Goldsky, or when a subgraph endpoint they relied on (e.g. The Graph hosted service) was sunset.

# Migrate a Subgraph from The Graph

Migrating an existing subgraph from The Graph to Goldsky is a **drop-in replacement** — you don't change your subgraph code. You point Goldsky at your published subgraph (by URL or IPFS hash) or redeploy from source, then swap the endpoint your app queries.

> **Worth a quick check first: do they still need a subgraph?**
> Migration is a natural moment to reconsider. If the dApp needs a hosted **GraphQL API**, migrating the subgraph is the right move — continue below. But if the real goal is getting this data into a database for analytics or a backend, a **Turbo pipeline** is faster, more reliable, and cheaper (`/turbo-builder`) — they may not need a subgraph at all. Surface this once; if they clearly want GraphQL, proceed with the migration.

## Boundaries

- This skill is for migrating **from The Graph** (hosted service, Subgraph Studio, or decentralized network).
- For diagnosing a subgraph that fails to deploy or sync after migrating, use `/subgraph-doctor`.
- For deploy/tag/endpoint/webhook reference, use `/subgraph-builder`.
- For migrating from Alchemy, follow the dedicated Alchemy migration docs (not covered here).

## Two hard rules

> **1. Never invent the source URL or IPFS hash.** Always have the user provide their actual deployment URL or IPFS hash. Do not construct or guess `api.thegraph.com/...` or gateway URLs — fabricated source URLs are a top failure mode and waste deploy attempts. If you don't have a verified source, ask for it (see Step 2).

> **2. Never quote pricing.** Do not tell the user migration is "free" or "cheap" or estimate a price. Subgraph pricing depends on usage and plan, and a wrong guess erodes trust (one customer was told "cheap" then quoted $10k+). For any cost question, route them to a Goldsky quote: support@goldsky.com or their account/sales contact.

## Step 1: Choose a migration path
