## What it does

The skill spells out how an agent should drive `@alchemy/cli`, Alchemy's command line for live blockchain queries, transaction signing and local automation. Commands are grouped by chain (`evm`, `solana`, `xchain`) and by product area (`wallet`, `app`, `webhook`, `auth`, `config`), and every one returns structured JSON. It is meant for work happening now in the session, not for code you ship: for application code the skill hands off to `alchemy-api` or `agentic-gateway`.

Before the first command, run `alchemy --json --no-interactive doctor` and `alchemy --json --no-interactive evm gas`. Skipping the second one is a mistake. There is a known false positive where `doctor` says the session is configured but RPC calls still fail with `AUTH_REQUIRED`, because no API key has been derived from the auth token yet. `evm gas` is the cheap smoke test that catches it. On that error, run `alchemy auth login` or `alchemy config set api-key <key>`, then repeat the check.

For onchain actions (`evm send`, `evm swap`, `xchain bridge`, `solana send`) the skill tells the agent to confirm the session with `alchemy --json --no-interactive wallet status --verify` first, and to prefer `--dry-run` before broadcasting. Sponsorship policies (`--gas-policy-id`, `--fee-policy-id`) are treated as fee controls, not as wallet spend limits. In headless setups such as SSH or CI, login goes through `alchemy auth login --device-code`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-cli -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-cli -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-cli -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install alchemyplatform/skills alchemy-cli
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-cli -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/alchemyplatform/skills --path skills/alchemy-cli
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add alchemyplatform/skills --skill alchemy-cli -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/alchemyplatform/skills/tree/HEAD/skills/alchemy-cli/SKILL.md

## When to use it
- check an address balance and transaction history without opening an explorer
- pull NFT and token holdings for a wallet
- simulate a contract call before it goes onchain
- trace a failed transaction to find the revert
- set up a webhook for onchain events

## Example prompts
- Check that the CLI is configured: run doctor and evm gas, and fix it if you get AUTH_REQUIRED
- Show the latest transactions for this address and trace the one that failed
- Simulate this contract call and show me the result, don't broadcast it

name: alchemy-cli
description: Use the Alchemy CLI (`@alchemy/cli`) for live blockchain data, transaction lookups, NFT/token/portfolio queries, simulation, tracing/debugging, contract reads/writes, wallet-signed sends, swaps and cross-chain bridges, Solana RPC/DAS plus wallet sends, webhook management, and Alchemy app administration. Preferred runtime path for live agent work (querying, admin, local automation) when the CLI is installed locally — or when both CLI and MCP are available. If neither is installed, install the CLI with `npm i -g @alchemy/cli`. Use for live agent work in this session, not for building application code that ships to production. For application code, use the `alchemy-api` skill (with API key) or `agentic-gateway` skill (without).
license: MIT
compatibility: Requires `@alchemy/cli` (`npm i -g @alchemy/cli`) and shell access. Works across Claude Code, Cursor, Codex, and any agent with shell access.

# Alchemy CLI

Use the [Alchemy CLI](https://www.npmjs.com/package/@alchemy/cli) (`@alchemy/cli`) for live blockchain queries, admin work, transaction signing, and local automation from the terminal. The CLI groups commands by chain (`evm`, `solana`, `xchain`) and by product area (`wallet`, `app`, `webhook`, `auth`, `config`), each with structured JSON output.

## When to use this skill

Use `alchemy-cli` when **all** of the following are true:

- The user wants **live agent work** — live querying, analysis, admin work, or local automation that the agent runs now in this session
- `@alchemy/cli` is installed locally, **or** both the CLI and an MCP server are available, **or** neither is available (in which case install the CLI — see [Install](#install))

The CLI is the **preferred local fallback runtime path** for live agent work. When in doubt about CLI vs MCP, prefer the CLI.

## When to use a different skill

| Situation | Use this skill instead |
| --- | --- |
| MCP is already wired into your client and the CLI is **not** installed locally | `alchemy-mcp` |
| Building application code that runs outside this agent session, with an Alchemy API key | `alchemy-api` |
| Building application code without an API key, or as an autonomous agent that needs to pay for itself, or you explicitly want x402/MPP | `agentic-gateway` |
```
