  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Alchemy Core Workflow A is an agent skill from jeremylongshore/tons-of-skills-marketplace. Design a multi-chain holdings workflow on Alchemy Portfolio APIs with explicit pagination, partial-failure, privacy, and reconciliation contracts. Use when building wallet portfolio views. Trigger with "Alchemy portfolio", "multi-chain token balances", or "wallet holdings dashboard".

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 Business, Finance & HR, covering Accounting and bookkeeping. 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

  • Building wallet portfolio views
  • With Alchemy portfolio
  • Multi-chain token balances
  • Wallet holdings dashboard

Example prompts

  • “Alchemy portfolio”
  • “multi-chain token balances”
  • “wallet holdings dashboard”
  • “/alchemy-core-workflow-a”

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. Define the supported network set, address source, freshness SLO, display currency, pagination limit, and completeness status shown to users.
  2. Confirm every requested Portfolio network in current documentation and validate each address before provider access.
  3. Call the appropriate Portfolio token or NFT endpoint through a response-validating adapter; retain the request's network set with the…
  4. Persist successful network pages and surface top-level error.partialErrors as named unavailable networks rather than dropping them.
  5. Continue cursors only for successful result sets; retry each failed network as a fresh request within a bounded budget and reconcile…
  6. Prove empty, partial, paginated, stale, and total-provider-failure states in the UI/API, then document cache invalidation and data deletion.

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 Core Workflow A loads about 1.3k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 554 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
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
~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 Multi-Chain Portfolio Workflow

Overview

Design a multi-chain holdings workflow on Alchemy Portfolio APIs with explicit pagination, partial-failure, privacy, and reconciliation contracts. 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

Portfolio APIs aggregate fungible tokens and NFTs across requested networks. Multi-network fanout can return HTTP 200 while reporting error.partialErrors; failed networks can be absent from pagination. Therefore HTTP success is not completeness, and retries for failed networks begin as fresh bounded requests rather than continuing the successful-network cursor.

Authentication

Use an application API key appropriate to Portfolio APIs and keep it in the approved server boundary. Wallet addresses are personal or customer-linked data when the product context makes them identifiable; apply the declared notice, consent, retention, and logging policy.

Instructions

  1. Define the supported network set, address source, freshness SLO, display currency, pagination limit, and completeness status shown to users.
  2. Confirm every requested Portfolio network in current documentation and validate each address before provider access.
  3. Call the appropriate Portfolio token or NFT endpoint through a response-validating adapter; retain the request's network set with the result.
  4. Persist successful network pages and surface top-level error.partialErrors as named unavailable networks rather than dropping them.
  5. Continue cursors only for successful result sets; retry each failed network as a fresh request within a bounded budget and reconcile without duplicating holdings.
  6. Prove empty, partial, paginated, stale, and total-provider-failure states in the UI/API, then document cache invalidation and data deletion.

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

Product and privacy owners approve address collection and retention. Operations approves freshness and degraded-mode semantics. Exporting addresses or holdings, increasing retention, or adding networks requires explicit approval.

Error Handling

  • Never label an HTTP 200 response complete until partialErrors, requested networks, and pagination have been reconciled.
  • Do not continue a successful-network page key for a network that failed out of the original response.
  • Do not convert missing price or metadata into a zero-valued asset.

Output

Return the network/address contract, validated adapter schema, pagination and partial-error state machine, cache policy, privacy controls, degraded UX, reconciliation evidence, and rollback. Mark assumptions, observations, source dates, environment-specific behavior, owners, and unresolved gaps explicitly.

Examples

  • Render Ethereum and Base holdings while explicitly marking a failed Arbitrum query unavailable, then retry Arbitrum as a fresh bounded request.
  • Show an empty portfolio as a valid complete result only when every requested network completed and pagination is exhausted.

Validation

Exercise and record expected and observed results for:

  • empty complete wallet
  • multi-page success
  • HTTP 200 with partialErrors
  • one failed network retry
  • duplicate reconciliation
  • data-deletion request

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.
