What it does
Alchemy Security Basics is an agent skill from jeremylongshore/tons-of-skills-marketplace. Analyze and secure Alchemy credentials, browser access, wallet authority, webhook verification, and untrusted chain data. Use when securing an Alchemy-backed application. Trigger with "secure Alchemy", "Alchemy API key exposure", or "verify an Alchemy webhook".
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 Webhooks. 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
- Securing an Alchemy-backed application
- With secure Alchemy
- Alchemy API key exposure
- Verify an Alchemy webhook
Example prompts
- “secure Alchemy”
- “Alchemy API key exposure”
- “verify an Alchemy webhook”
- “/alchemy-security-basics”
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.

- Verify Notify payloads against the raw body using HMAC-SHA256 and the per-webhook signing key before parsing or side effects.
- Run source, artifact, log, browser-bundle, and configuration secret scans; exercise rotation and incident response before production.
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:
ReadGlobGrepWriteEdit
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.

Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.

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

From compatibility in the SKILL.md frontmatter.
Context cost
Alchemy Security Basics loads about 1.3k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 549 words of instructions outside code blocks.
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 Credential and Trust-Boundary Security
Overview
Analyze and secure Alchemy credentials, browser access, wallet authority, webhook verification, and untrusted chain data. 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
An Alchemy application key identifies and limits provider access but is not a wallet private key. Frontend use is not categorically forbidden: current guidance supports explicit allowlists and recommends short-lived JWTs where appropriate. Admin keys, Notify tokens, webhook signing keys, and transaction signing authority remain server-side and separately controlled.
Authentication
Create a credential matrix covering application keys, access keys, Admin access, Notify management, webhook verification, and wallet signers. Assign owner, storage, runtime, scopes/allowlists, rotation, revocation, monitoring, and incident procedure to each.
Instructions
- Map browser, edge, server, CI, webhook, admin, and wallet trust boundaries and the data crossing each boundary.
- Choose server header auth for confidential workloads; if browser access is justified, apply exact allowlists or short-lived JWTs and test bypass conditions.
- Validate chain IDs, addresses, block selectors, contract ABIs, method allowlists, response sizes, and remote NFT metadata before use.
- Keep read clients separate from signers; require explicit transaction simulation, user intent, policy checks, and approval in a distinct workflow.
- Verify Notify payloads against the raw body using HMAC-SHA256 and the per-webhook signing key before parsing or side effects.
- Run source, artifact, log, browser-bundle, and configuration secret scans; exercise rotation and incident response before production.
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.
Show full SKILL.md (209 more words)Show less
Approval Boundaries
Security approves browser keys, JWT issuers, secret stores, signing boundaries, and incident response. Wallet transactions, new allowlists, credential rotation, or revocation require the named owner.
Error Handling
- Do not compare webhook signatures with ordinary string equality or after reserializing JSON.
- Do not let an application API key or read client imply transaction-signing permission.
- If credential material is exposed, fail closed, rotate or revoke it, inspect downstream use, and preserve a redacted receipt.
Output
Return the threat model, credential matrix, browser/server decision, input and response controls, signer separation, webhook verification contract, scan evidence, rotation exercise, and open risks. Mark assumptions, observations, source dates, environment-specific behavior, owners, and unresolved gaps explicitly.
Examples
- Approve a restricted browser read only after proving the configured origin allowlist rejects an unlisted origin and the bundle contains no broader credential.
- Reject a webhook whose signature is valid only after JSON reserialization because verification must cover the exact raw body.
Validation
Exercise and record expected and observed results for:
- unlisted browser origin
- expired short-lived JWT
- wrong chain
- oversized response
- bad webhook signature
- secret canary in build artifact
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.
