What it does
Explorer Contract Verification is an agent skill from sablier-labs/evm-monorepo. Verify smart contracts on Etherscan, Routescan, and Blockscout block explorers. This skill should be used when the user asks to "verify contract", "verify on etherscan", "verify on blockscout", "verify on routescan", "verify on chain scan". Handles standard verification, Etherscan V2 API, Routescan, Blockscout verification, proxy patterns, and factory-created contracts.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/examples.md` and `references/special-cases.md`).
It sits in Backend & APIs, covering Smart contracts. It works with Ethereum. 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
- Asks to verify contract
- Verify on etherscan
- Verify on blockscout
- Verify on routescan
Example prompts
- “verify contract”
- “verify on etherscan”
- “verify on blockscout”
- “/explorer-contract-verification”
Requirements
- A credential in ETHERSCAN_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit f317dc2. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.routescan.iophoenix.lightlink.ioexplorer.mode.networkexplorer-api.morphl2.iocontracts.conduit.xyzapi.etherscan.io
Also links to:
docs.etherscan.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ETHERSCAN_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Explorer Contract Verification loads about 1.9k tokens when it runs, and up to ~6.3k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 559 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 559 words (~1,925 tokens).
“This skill is coordination-exempt: skip the ai-coord gate for its declared work.”
