What it does
Setup Verdaccio Env is an agent skill from NomicFoundation/edr. Set up a local Verdaccio environment to test EDR + Hardhat 3 + a third-party repo (e.g. openzeppelin-contracts). Builds EDR with a chosen Rust profile, publishes EDR and Hardhat packages to a local Verdaccio registry, and installs them in the target repo. Use when you need to test local EDR changes in a realistic npm-installed setup.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with npm, OpenZeppelin and Rust. The repository describes itself as: An Ethereum development runtime implementation that can be reused to build new developer tools.
When your agent uses it
- You need to test local EDR changes in a realistic npm-installed setup
Example prompts
- “/setup-verdaccio-env”
Requirements
- Node.js
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Build EDR
- Start Verdaccio
- Publish the local EDR build to Verdaccio
- Bump and publish Hardhat packages to Verdaccio
- Install in the target repo
- Validate
- Cleanup reminder
What it can do on your machine
Read from SKILL.md and the folder at commit 2c0accf. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pnpmgitnpmyarn
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, git, npm and yarn, which can reach the network depending on how they are called.
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.
Context cost
Setup Verdaccio Env loads about 1.6k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 606 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: warnings
The automated check found patterns that need a careful read before installing.

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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 606 words (~1,584 tokens).
“This skill sets up a local Verdaccio npm registry and publishes locally-built EDR and Hardhat packages to it, then installs them in a third-party target repo. This avoids situations where pnpm link is not sufficient and ensures the target repo…”
