What it does

Alchemy Install Auth is an agent skill from jeremylongshore/tons-of-skills-marketplace. Select and prove the current Alchemy client, key type, network, and authentication boundary before integration work. Use when creating or repairing Alchemy connectivity. Trigger with "set up Alchemy", "configure an Alchemy API key", or "choose viem or Wallet APIs".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; live Alchemy access requires network access, an appropriate credential, account capacity, and explicit approval

It sits in Backend & APIs, covering Authentication. It works with viem and wagmi and Solana. 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. The licence is MIT.

When your agent uses it

  • Repairing Alchemy connectivity
  • With set up Alchemy
  • Configure an Alchemy API key

Example prompts

  • “set up Alchemy”
  • “configure an Alchemy API key”
  • “choose viem or Wallet APIs”
  • “/alchemy-install-auth”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code; live Alchemy access requires network access, an appropriate credential, account capacity, and explicit approval
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Classify the requested capability as Node RPC, Data API, Portfolio, Wallet APIs, Notify management, webhook receipt, Admin usage, or Solana.
  2. Confirm the required chain and feature in the live supported-chain and feature-support matrices; do not infer feature parity from RPC…
  3. Select viem, direct HTTP, @alchemy/wallet-apis, or Solana Web3.js from the capability—not from the archived SDK examples.
  4. Create or identify a non-production application and a least-privilege key; separately identify any Admin access key or Notify token…
  5. Configure the credential through the repository's established secret mechanism and document whether requests use a server header, server…
  6. Run one read-only chain-specific proof, record the redacted request shape and response, then document rotation, revocation, owner…

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code; live Alchemy access requires network access, an appropriate credential, account capacity, and explicit approval

    From compatibility in the SKILL.md frontmatter.

Context cost

Alchemy Install Auth loads about 1.3k tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 609 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Alchemy Installation and Authentication Intake

Overview

Select and prove the current Alchemy client, key type, network, and authentication boundary before integration work. This workflow produces a reviewable artifact and negative-path evidence before any live side effect.

Prerequisites

  • Current first-party Alchemy documentation for the selected product, chain, feature, client, authentication method, limit, and lifecycle.
  • Named product, application, security, data/privacy, budget, release, and operations owners appropriate to the requested scope.
  • Synthetic or approved non-production fixtures, a credential canary, explicit success criteria, and a tested rollback boundary.

Current Contract

The legacy alchemy-sdk JavaScript repository is archived and deprecated. New EVM reads use viem or direct documented HTTP APIs; transacting applications and Portfolio support use @alchemy/wallet-apis; Solana work uses Solana Web3.js. An application API key, an Admin access key, a Notify auth token, and a webhook signing key are different credentials and are not interchangeable.

Authentication

Prefer server-side request-header authentication for confidential workloads. A browser key is acceptable only when the current Alchemy guidance, explicit domain allowlists, least privilege, and the product threat model allow it; short-lived JWTs are the stronger frontend option. Store Admin, Notify, webhook, and signing credentials only in approved secret storage.

Instructions

  1. Classify the requested capability as Node RPC, Data API, Portfolio, Wallet APIs, Notify management, webhook receipt, Admin usage, or Solana.
  2. Confirm the required chain and feature in the live supported-chain and feature-support matrices; do not infer feature parity from RPC support.
  3. Select viem, direct HTTP, @alchemy/wallet-apis, or Solana Web3.js from the capability—not from the archived SDK examples.
  4. Create or identify a non-production application and a least-privilege key; separately identify any Admin access key or Notify token actually required.
  5. Configure the credential through the repository's established secret mechanism and document whether requests use a server header, server URL, or approved restricted browser boundary.
  6. Run one read-only chain-specific proof, record the redacted request shape and response, then document rotation, revocation, owner transfer, and environment separation.

Tool Discipline

Use Read, Glob, and Grep to inspect current documentation, configuration, code, fixtures, and evidence. Use Write and Edit only for approved repository artifacts. Skill invocation alone does not authorize network access, credentials, wallet addresses, customer data, plan changes, spend, key creation or rotation, webhook changes, deployment, replay, transaction construction, signing, broadcast, or deletion.

Approval Boundaries

The application owner selects the product and chain. Security approves any browser credential boundary and production secret store. Creating, rotating, revoking, or deleting a live key requires explicit approval from its owner.

Error Handling

  • A valid key on an unsupported feature or chain is not a successful setup.
  • Do not substitute an application API key for an Admin access key, Notify token, or webhook signing key.
  • If a secret appears in source, logs, or artifacts, stop, revoke or rotate it, remove the exposure, and preserve a redacted incident receipt.

Output

Return the capability-to-client decision, chain/feature proof, credential-class matrix, redacted connectivity result, secret lifecycle, owners, evidence date, and unresolved gaps. Mark assumptions, observations, source dates, environment-specific behavior, owners, and unresolved gaps explicitly.

Examples

  • For a server-rendered Ethereum balance view, select viem, prove one read with a development app key, and keep the production key in the server secret boundary.
  • For a transacting smart-wallet application, select Wallet APIs v5 and reject an archived alchemy-sdk bootstrap even if an old repository still imports it.

Validation

Exercise and record expected and observed results for:

  • wrong chain
  • unsupported feature on a supported chain
  • missing or invalid key
  • application key supplied to an Admin endpoint
  • revoked key
  • secret-canary scan

Resources

  • Current first-party evidence map — recheck dated Alchemy sources before execution.
  • Treat observed account, application, network, indexer, chain, or provider behavior as environment-specific evidence, never a universal guarantee.
