What it does

Solidity Coding is an agent skill from sablier-labs/evm-monorepo. Write production-quality Solidity contracts. Trigger phrases - write contract, implement function, add feature, add error, gas optimization, event design, contract architecture, or when working in src/ directories.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `agents/openai.yaml`, `references/coding-patterns.md` and `references/event-design.md`).

It sits in Backend & APIs, covering Smart contracts. It works with Solidity. The repository describes itself as: Monorepo for Sablier's EVM smart contracts including Lockup, Flow, Airdrops, Bob and Utils protocols.

When your agent uses it

  • Phrases - write contract
  • Implement function
  • Gas optimization
  • Contract architecture

Example prompts

  • “/solidity-coding”

Workflow steps

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

  1. Named imports only: import { IERC20 } from "...".
  2. Two groups separated by a blank line: package imports (including @sablier/*), then relative local imports.
  3. Sort each group alphabetically by import path.

What it can do on your machine

Read from SKILL.md and the folder at commit 1934445. 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:

    • just

    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.

Context cost

Solidity Coding loads about 2k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 621 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~10k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 621 words (~2,011 tokens).

“This skill provides expertise for writing production-quality Solidity contracts following industry best practices.”

Questions about Solidity Coding

What does Solidity Coding do?

When should I use Solidity Coding?

Solidity Coding fits situations like: phrases - write contract; implement function; gas optimization; contract architecture.

How do I install Solidity Coding in Claude Code?

Run `npx skills add sablier-labs/evm-monorepo --skill solidity-coding -a claude-code`. Or copy the skill folder (.agents/skills/solidity-coding in sablier-labs/evm-monorepo) into .claude/skills/solidity-coding in your project. Claude Code loads it when a task matches its description.

How do I install Solidity Coding in Codex?

Run `npx skills add sablier-labs/evm-monorepo --skill solidity-coding -a codex`. Or copy the skill folder (.agents/skills/solidity-coding in sablier-labs/evm-monorepo) into .agents/skills/solidity-coding in your project. Codex loads it when a task matches its description.

Can I use Solidity Coding in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add sablier-labs/evm-monorepo --skill solidity-coding -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/solidity-coding, .gemini/skills/solidity-coding, .github/skills/solidity-coding and .opencode/skills/solidity-coding in your project.

What does Solidity Coding need to run?

Going by SKILL.md and its folder, Solidity Coding needs the command-line tools its instructions call (just).

Does Solidity Coding access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Solidity Coding safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Solidity Coding use?

Solidity Coding has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Solidity Coding use?

About 2k tokens (SKILL.md is roughly 8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 8.4k tokens, read only when the agent opens those files.

What are the alternatives to Solidity Coding?

Skills that share tags, products or a category with Solidity Coding: Fizz Convert (pashov/skills, 1.2k stars), Feynman Auditor (0xiehnnkta/nemesis-auditor, 244 stars), Smart Contract Audit (greatpie/smart-contract-audit-skill, 101 stars) and Radar (Auditware/radar, 154 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
