What Alchemy Pack is

Alchemy Pack is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”

A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.

Installing Alchemy Pack adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.

How to install Alchemy Pack

Claude Code

Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
Install the plugin: claude plugin install alchemy-pack@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
Restart the session if the new skills or commands don't appear straight away.

Claude Cowork

Open Customize → Plugins and choose Add marketplace.
Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).

Inside the source file

An excerpt from plugins/saas-packs/alchemy-pack/.claude-plugin/plugin.json, shared under the repository's MIT license. Read the full file on GitHub.

Eighteen evidence-backed Claude Code workflows for operating Alchemy Node, Data, Portfolio, NFT, Wallet, Notify, and Admin surfaces across current supported chains.

Every skill includes a dated first-party evidence map, explicit credential and approval boundaries, negative-path validation, and a rollback-aware output contract. The pack no longer teaches the deprecated and archived alchemy-sdk, Polygon Mumbai, fixed plan or method-cost tables, an undocumented dashboard stats endpoint, or blanket claims that every application key must stay out of browser code.

Installation

/plugin install alchemy-pack@claude-code-plugins-plus

Operator lanes

Current non-negotiables

The alchemy-sdk JavaScript repository is archived and deprecated. Use viem for JavaScript EVM reads, current Data API adapters for product endpoints, @alchemy/wallet-apis for transacting applications and Portfolio support, and Solana Web3.js for Solana.
An application API key, Admin access key, Notify management token, per-webhook signing key, and wallet signing authority are distinct credentials.
RPC support on a chain does not prove feature support for NFT, Portfolio, Wallet, Simulation, or Notify surfaces.
Portfolio fanout can return HTTP 200 with top-level error.partialErrors; HTTP success is not proof of a complete multi-chain result.
Throughput is account-level over a rolling ten-second token-bucket window. Pricing, method costs, included capacity, and elastic behavior must be checked against current account evidence.
Notify authenticity uses HMAC-SHA256 over the exact raw body and the per-webhook signing key in X-Alchemy-Signature.
Restricted browser application-key patterns require an explicit threat model and current Alchemy controls such as allowlists or short-lived JWTs; confidential, Admin, Notify, webhook, and signing credentials remain isolated.

Quality contract

All eighteen skills target marketplace Grade A and Tier-2 GREEN with zero warnings and errors. Each skill uses only Read, Glob, Grep, Write, and Edit; invoking a skill never authorizes network access, credentials, address or customer data, plan changes, spend, key or webhook lifecycle changes, deployment, replay, transaction construction, signing, broadcast, or deletion.

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
