What it does

Kleros Ipfs Upload is an agent skill from aiskillstore/marketplace. Upload files to IPFS through the Kleros x402 payment gateway for $0.01 USDC on Base mainnet. Use specifically for Kleros ecosystem content such as dispute evidence, meta-evidence JSON, court, dispute, or arbitrator policies, Curate item metadata, juror justifications, and artifacts referenced by Kleros contracts or subgraphs through an IPFS CID. Trigger on Kleros, court, arbitrator, dispute, juror, Curate, Proof of Humanity, evidence, meta-evidence, or justification context. Do not use for generic IPFS uploads or…

Its SKILL.md is about 4.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `scripts/package.json`, `scripts/pay-and-upload-cdp.ts` and `scripts/pay-and-upload.ts`).

It sits in Testing & QA. It works with x402, Circle USDC and Netlify. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Proof of Humanity
  • Justification context
  • Generic IPFS uploads
  • CID requests without Kleros context

Example prompts

  • “/kleros-ipfs-upload”

Requirements

  • Node.js
  • A credential in EVM_PRIVATE_KEY
  • A credential in CDP_API_KEY_SECRET

Workflow steps

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

  1. Generate a key — any EVM-compatible keypair works. Run this to print a fresh one
  2. Fund it — send USDC on Base to the derived address. Any centralised exchange that supports Base withdrawals works.
  3. Store the key in EVM_PRIVATE_KEY.

What it can do on your machine

Read from SKILL.md and the folder at commit 44923f3. 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

    Ships 3 files in scripts/ (TypeScript), which the agent can run.

    Shell commands in SKILL.md call:

    • npx
    • npm
    • curl
    • jq
    • node

    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:

    • kleros-ipfs-gateway.fly.dev
    • cdn.kleros.link

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • EVM_PRIVATE_KEY
    • CDP_API_KEY_ID
    • CDP_API_KEY_SECRET
    • CDP_WALLET_SECRET
    • API_KEY_ID
    • API_KEY_SECRET
    • WALLET_SECRET

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

Context cost

Kleros Ipfs Upload loads about 4.4k tokens when it runs. Until then it costs about 193 tokens; SKILL.md has 1,970 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~193
When it runs · the whole SKILL.md, loaded when a task matches
~4.4k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:139
    mmand line, point `CDP_CREDS_PATH` at a `.env`-style file containing `CDP_API_KEY_ID`, `CDP_API_KEY_SECRET`, `CDP_WALLET

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,970 words (~4,371 tokens).

“Upload Kleros-ecosystem files to IPFS via https://kleros-ipfs-gateway.fly.dev/upload-to-ipfs, an x402-protected gateway that charges $0.01 USDC per upload on Base mainnet. The returned IPFS CID is content-addressable and dereferenceable through any IPFS gateway, and indexed by Kleros's Graph Node for subgraph discoverability.”
