  • SKILL.md covers Overview, Prerequisites, Instructions and Tool Discipline, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Quicknode Core Workflow A is an agent skill from jeremylongshore/tons-of-skills-marketplace. Design a safe EVM transaction-submission path over QuickNode with simulation, fee and nonce policy, signer isolation, broadcast identity, and confirmation rules. Use when moving a read-only integration into transaction writes. Trigger with: "send transactions through QuickNode", "build an EVM write path", "harden QuickNode transaction submission".

Its SKILL.md is about 970 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: EVM method availability, fee fields, and finality rules vary by chain and network

It sits in Backend & APIs, covering Smart contracts. 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

  • Moving a read-only integration into transaction writes
  • With: send transactions through QuickNode
  • Build an EVM write path
  • Harden QuickNode transaction submission

Example prompts

  • “send transactions through QuickNode”
  • “build an EVM write path”
  • “harden QuickNode transaction submission”
  • “/quicknode-core-workflow-a”

Requirements

  • Compatibility (from SKILL.md): EVM method availability, fee fields, and finality rules vary by chain and network
  • Pre-approved tools (allowed-tools): Read, Grep, Write, Edit

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Inspect the existing path
  2. Define transaction intent
  3. Simulate and estimate
  4. Coordinate nonce and fees
  5. Sign and broadcast once
  6. Confirm by policy

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
    • 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

    Links to these hosts (documentation or services it may open):

    • quicknode.com

    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

    EVM method availability, fee fields, and finality rules vary by chain and network

    From compatibility in the SKILL.md frontmatter.

Context cost

Quicknode Core Workflow A loads about 970 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 94 tokens; SKILL.md has 404 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~94
When it runs · the whole SKILL.md, loaded when a task matches
~970
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

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.

QuickNode EVM Transaction Safety

Overview

Build a write path that treats signing, submission, and confirmation as separate state transitions. QuickNode transports the signed transaction; the application remains responsible for intent, signer custody, nonce coordination, chain identity, and reorganization policy.

Prerequisites

  • A verified QuickNode endpoint and expected EVM chain ID
  • A testnet signer held outside source code
  • Contract ABI, write intent, value ceiling, and confirmation policy

Instructions

Step 1: Inspect the existing path

Use Read and Grep to find signers, private-key variables, nonce overrides, fee logic, retries, and receipt assumptions. Stop if secrets or signed raw transactions are logged.

Step 2: Define transaction intent

Use Write or Edit to express destination, calldata, value, chain ID, and caller policy as validated inputs. Reject unexpected networks and unbounded value before reaching the signer.

Step 3: Simulate and estimate

Run the equivalent read call and gas estimate at an explicit block tag when supported. Treat a revert as an application or chain-state result, not a transient provider failure.

Step 4: Coordinate nonce and fees

Assign one nonce owner per signer. Read pending nonce state, define replacement rules, and use chain-appropriate fee fields. Do not blindly overwrite a nonce or double fees on each timeout.

Step 5: Sign and broadcast once

Keep signing in a wallet, HSM, or approved remote signer. Persist the signed transaction hash before submission. On an ambiguous timeout, query by hash before broadcasting again.

Show full SKILL.md (171 more words)Show less
Step 6: Confirm by policy

Track inclusion, receipt status, block hash, and the required chain-specific confirmation depth. Reconcile dropped or reorganized receipts and expose a durable business-operation idempotency key.

Tool Discipline

Use Read and Grep for transaction-path discovery and Write/Edit for validation, state-machine, and tests. This skill never asks the agent to hold a private key or execute a funded transaction.

Output

  • Validated transaction-intent schema
  • Signer, nonce, fee, and broadcast ownership contract
  • Ambiguous-submission reconciliation path
  • Chain-specific confirmation and reorg policy

Examples

A payment request is recorded before signing. If broadcast times out, the worker searches for the known transaction hash and never manufactures a second payment from the same business request.

Error Handling

FailureResponse
Simulation revertsDecode against ABI and state; do not retry automatically
Nonce too lowReconcile pending and mined transactions for the signer
Broadcast timeoutQuery the persisted hash before deciding whether to resubmit
Receipt disappearsReturn to pending and apply the documented reorg policy
